Essay on Pollution for Students and Children

500+ words essay on pollution.

Pollution is a term which even kids are aware of these days. It has become so common that almost everyone acknowledges the fact that pollution is rising continuously. The term ‘pollution’ means the manifestation of any unsolicited foreign substance in something. When we talk about pollution on earth, we refer to the contamination that is happening of the natural resources by various pollutants . All this is mainly caused by human activities which harm the environment in ways more than one. Therefore, an urgent need has arisen to tackle this issue straightaway. That is to say, pollution is damaging our earth severely and we need to realize its effects and prevent this damage. In this essay on pollution, we will see what are the effects of pollution and how to reduce it.

Effects of Pollution

Pollution affects the quality of life more than one can imagine. It works in mysterious ways, sometimes which cannot be seen by the naked eye. However, it is very much present in the environment. For instance, you might not be able to see the natural gases present in the air, but they are still there. Similarly, the pollutants which are messing up the air and increasing the levels of carbon dioxide is very dangerous for humans. Increased level of carbon dioxide will lead to global warming .

Further, the water is polluted in the name of industrial development, religious practices and more will cause a shortage of drinking water. Without water, human life is not possible. Moreover, the way waste is dumped on the land eventually ends up in the soil and turns toxic. If land pollution keeps on happening at this rate, we won’t have fertile soil to grow our crops on. Therefore, serious measures must be taken to reduce pollution to the core.

How to Reduce Pollution?

After learning the harmful effects of pollution, one must get on the task of preventing or reducing pollution as soon as possible. To reduce air pollution, people should take public transport or carpool to reduce vehicular smoke. While it may be hard, avoiding firecrackers at festivals and celebrations can also cut down on air and noise pollution. Above all, we must adopt the habit of recycling. All the used plastic ends up in the oceans and land, which pollutes them.

So, remember to not dispose of them off after use, rather reuse them as long as you can. We must also encourage everyone to plant more trees which will absorb the harmful gases and make the air cleaner. When talking on a bigger level, the government must limit the usage of fertilizers to maintain the soil’s fertility. In addition, industries must be banned from dumping their waste into oceans and rivers, causing water pollution.

To sum it up, all types of pollution is hazardous and comes with grave consequences. Everyone must take a step towards change ranging from individuals to the industries. As tackling this problem calls for a joint effort, so we must join hands now. Moreover, the innocent lives of animals are being lost because of such human activities. So, all of us must take a stand and become a voice for the unheard in order to make this earth pollution-free.

Pollution is the introduction of harmful materials into the environment . These harmful materials are called pollutants . Pollutants can be natural, such as volcanic ash . They can also be created by human activity, such as trash or runoff produced by factories. Pollutants damage the quality of air, water, and land. Many things that are useful to people produce pollution. Cars spew pollutants from their exhaust pipes. Burning coal to create electricity pollutes the air. Industries and homes generate garbage and sewage that can pollute the land and water. Pesticides —chemical poisons used to kill weeds and insects— seep into waterways and harm wildlife . All living things—from one-celled microbes to blue whales—depend on Earth ’s supply of air and water. When these resources are polluted, all forms of life are threatened. Pollution is a global problem. Although urban areas are usually more polluted than the countryside, pollution can spread to remote places where no people live. For example, pesticides and other chemicals have been found in the Antarctic ice sheet . In the middle of the northern Pacific Ocean, a huge collection of microscopic plastic particles forms what is known as the Great Pacific Garbage Patch . Air and water currents carry pollution. Ocean currents and migrating fish carry marine pollutants far and wide. Winds can pick up radioactive material accidentally released from a nuclear reactor and scatter it around the world. Smoke from a factory in one country drifts into another country. In the past, visitors to Big Bend National Park in the U.S. state of Texas could see 290 kilometers (180 miles) across the vast landscape . Now, coal-burning power plants in Texas and the neighboring state of Chihuahua, Mexico have spewed so much pollution into the air that visitors to Big Bend can sometimes see only 50 kilometers (30 miles). The three major types of pollution are air pollution , water pollution , and land pollution . Air Pollution Sometimes, air pollution is visible . A person can see dark smoke pour from the exhaust pipes of large trucks or factories, for example. More often, however, air pollution is invisible . Polluted air can be dangerous, even if the pollutants are invisible. It can make people’s eyes burn and make them have difficulty breathing. It can also increase the risk of lung cancer . Sometimes, air pollution kills quickly. In 1984, an accident at a pesticide plant in Bhopal, India, released a deadly gas into the air. At least 8,000 people died within days. Hundreds of thou sands more were permanently injured. Natural disasters can also cause air pollution to increase quickly. When volcanoes erupt , they eject volcanic ash and gases into the atmosphere . Volcanic ash can discolor the sky for months. After the eruption of the Indonesian volcano of Krakatoa in 1883, ash darkened the sky around the world. The dimmer sky caused fewer crops to be harvested as far away as Europe and North America. For years, meteorologists tracked what was known as the “equatorial smoke stream .” In fact, this smoke stream was a jet stream , a wind high in Earth’s atmosphere that Krakatoa’s air pollution made visible. Volcanic gases , such as sulfur dioxide , can kill nearby residents and make the soil infertile for years. Mount Vesuvius, a volcano in Italy, famously erupted in 79, killing hundreds of residents of the nearby towns of Pompeii and Herculaneum. Most victims of Vesuvius were not killed by lava or landslides caused by the eruption. They were choked, or asphyxiated , by deadly volcanic gases. In 1986, a toxic cloud developed over Lake Nyos, Cameroon. Lake Nyos sits in the crater of a volcano. Though the volcano did not erupt, it did eject volcanic gases into the lake. The heated gases passed through the water of the lake and collected as a cloud that descended the slopes of the volcano and into nearby valleys . As the toxic cloud moved across the landscape, it killed birds and other organisms in their natural habitat . This air pollution also killed thousands of cattle and as many as 1,700 people. Most air pollution is not natural, however. It comes from burning fossil fuels —coal, oil , and natural gas . When gasoline is burned to power cars and trucks, it produces carbon monoxide , a colorless, odorless gas. The gas is harmful in high concentrations , or amounts. City traffic produces highly concentrated carbon monoxide. Cars and factories produce other common pollutants, including nitrogen oxide , sulfur dioxide, and hydrocarbons . These chemicals react with sunlight to produce smog , a thick fog or haze of air pollution. The smog is so thick in Linfen, China, that people can seldom see the sun. Smog can be brown or grayish blue, depending on which pollutants are in it. Smog makes breathing difficult, especially for children and older adults. Some cities that suffer from extreme smog issue air pollution warnings. The government of Hong Kong, for example, will warn people not to go outside or engage in strenuous physical activity (such as running or swimming) when smog is very thick.

When air pollutants such as nitrogen oxide and sulfur dioxide mix with moisture, they change into acids . They then fall back to earth as acid rain . Wind often carries acid rain far from the pollution source. Pollutants produced by factories and power plants in Spain can fall as acid rain in Norway. Acid rain can kill all the trees in a forest . It can also devastate lakes, streams, and other waterways. When lakes become acidic, fish can’t survive . In Sweden, acid rain created thousands of “ dead lakes ,” where fish no longer live. Acid rain also wears away marble and other kinds of stone . It has erased the words on gravestones and damaged many historic buildings and monuments . The Taj Mahal , in Agra, India, was once gleaming white. Years of exposure to acid rain has left it pale. Governments have tried to prevent acid rain by limiting the amount of pollutants released into the air. In Europe and North America, they have had some success, but acid rain remains a major problem in the developing world , especially Asia. Greenhouse gases are another source of air pollution. Greenhouse gases such as carbon dioxide and methane occur naturally in the atmosphere. In fact, they are necessary for life on Earth. They absorb sunlight reflected from Earth, preventing it from escaping into space. By trapping heat in the atmosphere, they keep Earth warm enough for people to live. This is called the greenhouse effect . But human activities such as burning fossil fuels and destroying forests have increased the amount of greenhouse gases in the atmosphere. This has increased the greenhouse effect, and average temperatures across the globe are rising. The decade that began in the year 2000 was the warmest on record. This increase in worldwide average temperatures, caused in part by human activity, is called global warming . Global warming is causing ice sheets and glaciers to melt. The melting ice is causing sea levels to rise at a rate of two millimeters (0.09 inches) per year. The rising seas will eventually flood low-lying coastal regions . Entire nations, such as the islands of Maldives, are threatened by this climate change . Global warming also contributes to the phenomenon of ocean acidification . Ocean acidification is the process of ocean waters absorbing more carbon dioxide from the atmosphere. Fewer organisms can survive in warmer, less salty waters. The ocean food web is threatened as plants and animals such as coral fail to adapt to more acidic oceans. Scientists have predicted that global warming will cause an increase in severe storms . It will also cause more droughts in some regions and more flooding in others. The change in average temperatures is already shrinking some habitats, the regions where plants and animals naturally live. Polar bears hunt seals from sea ice in the Arctic. The melting ice is forcing polar bears to travel farther to find food , and their numbers are shrinking. People and governments can respond quickly and effectively to reduce air pollution. Chemicals called chlorofluorocarbons (CFCs) are a dangerous form of air pollution that governments worked to reduce in the 1980s and 1990s. CFCs are found in gases that cool refrigerators, in foam products, and in aerosol cans . CFCs damage the ozone layer , a region in Earth’s upper atmosphere. The ozone layer protects Earth by absorbing much of the sun’s harmful ultraviolet radiation . When people are exposed to more ultraviolet radiation, they are more likely to develop skin cancer, eye diseases, and other illnesses. In the 1980s, scientists noticed that the ozone layer over Antarctica was thinning. This is often called the “ ozone hole .” No one lives permanently in Antarctica. But Australia, the home of more than 22 million people, lies at the edge of the hole. In the 1990s, the Australian government began an effort to warn people of the dangers of too much sun. Many countries, including the United States, now severely limit the production of CFCs. Water Pollution Some polluted water looks muddy, smells bad, and has garbage floating in it. Some polluted water looks clean, but is filled with harmful chemicals you can’t see or smell. Polluted water is unsafe for drinking and swimming. Some people who drink polluted water are exposed to hazardous chemicals that may make them sick years later. Others consume bacteria and other tiny aquatic organisms that cause disease. The United Nations estimates that 4,000 children die every day from drinking dirty water. Sometimes, polluted water harms people indirectly. They get sick because the fish that live in polluted water are unsafe to eat. They have too many pollutants in their flesh. There are some natural sources of water pollution. Oil and natural gas, for example, can leak into oceans and lakes from natural underground sources. These sites are called petroleum seeps . The world’s largest petroleum seep is the Coal Oil Point Seep, off the coast of the U.S. state of California. The Coal Oil Point Seep releases so much oil that tar balls wash up on nearby beaches . Tar balls are small, sticky pieces of pollution that eventually decompose in the ocean.

Human activity also contributes to water pollution. Chemicals and oils from factories are sometimes dumped or seep into waterways. These chemicals are called runoff. Chemicals in runoff can create a toxic environment for aquatic life. Runoff can also help create a fertile environment for cyanobacteria , also called blue-green algae . Cyanobacteria reproduce rapidly, creating a harmful algal bloom (HAB) . Harmful algal blooms prevent organisms such as plants and fish from living in the ocean. They are associated with “ dead zones ” in the world’s lakes and rivers, places where little life exists below surface water. Mining and drilling can also contribute to water pollution. Acid mine drainage (AMD) is a major contributor to pollution of rivers and streams near coal mines . Acid helps miners remove coal from the surrounding rocks . The acid is washed into streams and rivers, where it reacts with rocks and sand. It releases chemical sulfur from the rocks and sand, creating a river rich in sulfuric acid . Sulfuric acid is toxic to plants, fish, and other aquatic organisms. Sulfuric acid is also toxic to people, making rivers polluted by AMD dangerous sources of water for drinking and hygiene . Oil spills are another source of water pollution. In April 2010, the Deepwater Horizon oil rig exploded in the Gulf of Mexico, causing oil to gush from the ocean floor. In the following months, hundreds of millions of gallons of oil spewed into the gulf waters. The spill produced large plumes of oil under the sea and an oil slick on the surface as large as 24,000 square kilometers (9,100 square miles). The oil slick coated wetlands in the U.S. states of Louisiana and Mississippi, killing marsh plants and aquatic organisms such as crabs and fish. Birds, such as pelicans , became coated in oil and were unable to fly or access food. More than two million animals died as a result of the Deepwater Horizon oil spill. Buried chemical waste can also pollute water supplies. For many years, people disposed of chemical wastes carelessly, not realizing its dangers. In the 1970s, people living in the Love Canal area in Niagara Falls, New York, suffered from extremely high rates of cancer and birth defects . It was discovered that a chemical waste dump had poisoned the area’s water. In 1978, 800 families living in Love Canal had to a bandon their homes. If not disposed of properly, radioactive waste from nuclear power plants can escape into the environment. Radioactive waste can harm living things and pollute the water. Sewage that has not been properly treated is a common source of water pollution. Many cities around the world have poor sewage systems and sewage treatment plants. Delhi, the capital of India, is home to more than 21 million people. More than half the sewage and other waste produced in the city are dumped into the Yamuna River. This pollution makes the river dangerous to use as a source of water for drinking or hygiene. It also reduces the river’s fishery , resulting in less food for the local community. A major source of water pollution is fertilizer used in agriculture . Fertilizer is material added to soil to make plants grow larger and faster. Fertilizers usually contain large amounts of the elements nitrogen and phosphorus , which help plants grow. Rainwater washes fertilizer into streams and lakes. There, the nitrogen and phosphorus cause cyanobacteria to form harmful algal blooms. Rain washes other pollutants into streams and lakes. It picks up animal waste from cattle ranches. Cars drip oil onto the street, and rain carries it into storm drains , which lead to waterways such as rivers and seas. Rain sometimes washes chemical pesticides off of plants and into streams. Pesticides can also seep into groundwater , the water beneath the surface of the Earth. Heat can pollute water. Power plants, for example, produce a huge amount of heat. Power plants are often located on rivers so they can use the water as a coolant . Cool water circulates through the plant, absorbing heat. The heated water is then returned to the river. Aquatic creatures are sensitive to changes in temperature. Some fish, for example, can only live in cold water. Warmer river temperatures prevent fish eggs from hatching. Warmer river water also contributes to harmful algal blooms. Another type of water pollution is simple garbage. The Citarum River in Indonesia, for example, has so much garbage floating in it that you cannot see the water. Floating trash makes the river difficult to fish in. Aquatic animals such as fish and turtles mistake trash, such as plastic bags, for food. Plastic bags and twine can kill many ocean creatures. Chemical pollutants in trash can also pollute the water, making it toxic for fish and people who use the river as a source of drinking water. The fish that are caught in a polluted river often have high levels of chemical toxins in their flesh. People absorb these toxins as they eat the fish. Garbage also fouls the ocean. Many plastic bottles and other pieces of trash are thrown overboard from boats. The wind blows trash out to sea. Ocean currents carry plastics and other floating trash to certain places on the globe, where it cannot escape. The largest of these areas, called the Great Pacific Garbage Patch, is in a remote part of the Pacific Ocean. According to some estimates, this garbage patch is the size of Texas. The trash is a threat to fish and seabirds, which mistake the plastic for food. Many of the plastics are covered with chemical pollutants. Land Pollution Many of the same pollutants that foul the water also harm the land. Mining sometimes leaves the soil contaminated with dangerous chemicals. Pesticides and fertilizers from agricultural fields are blown by the wind. They can harm plants, animals, and sometimes people. Some fruits and vegetables absorb the pesticides that help them grow. When people consume the fruits and vegetables, the pesticides enter their bodies. Some pesticides can cause cancer and other diseases. A pesticide called DDT (dichlorodiphenyltrichloroethane) was once commonly used to kill insects, especially mosquitoes. In many parts of the world, mosquitoes carry a disease called malaria , which kills a million people every year. Swiss chemist Paul Hermann Muller was awarded the Nobel Prize for his understanding of how DDT can control insects and other pests. DDT is responsible for reducing malaria in places such as Taiwan and Sri Lanka. In 1962, American biologist Rachel Carson wrote a book called Silent Spring , which discussed the dangers of DDT. She argued that it could contribute to cancer in humans. She also explained how it was destroying bird eggs, which caused the number of bald eagles, brown pelicans, and ospreys to drop. In 1972, the United States banned the use of DDT. Many other countries also banned it. But DDT didn’t disappear entirely. Today, many governments support the use of DDT because it remains the most effective way to combat malaria. Trash is another form of land pollution. Around the world, paper, cans, glass jars, plastic products, and junked cars and appliances mar the landscape. Litter makes it difficult for plants and other producers in the food web to create nutrients . Animals can die if they mistakenly eat plastic. Garbage often contains dangerous pollutants such as oils, chemicals, and ink. These pollutants can leech into the soil and harm plants, animals, and people. Inefficient garbage collection systems contribute to land pollution. Often, the garbage is picked up and brought to a dump, or landfill . Garbage is buried in landfills. Sometimes, communities produce so much garbage that their landfills are filling up. They are running out of places to dump their trash. A massive landfill near Quezon City, Philippines, was the site of a land pollution tragedy in 2000. Hundreds of people lived on the slopes of the Quezon City landfill. These people made their living from recycling and selling items found in the landfill. However, the landfill was not secure. Heavy rains caused a trash landslide, killing 218 people. Sometimes, landfills are not completely sealed off from the land around them. Pollutants from the landfill leak into the earth in which they are buried. Plants that grow in the earth may be contaminated, and the herbivores that eat the plants also become contaminated. So do the predators that consume the herbivores. This process, where a chemical builds up in each level of the food web, is called bioaccumulation . Pollutants leaked from landfills also leak into local groundwater supplies. There, the aquatic food web (from microscopic algae to fish to predators such as sharks or eagles) can suffer from bioaccumulation of toxic chemicals. Some communities do not have adequate garbage collection systems, and trash lines the side of roads. In other places, garbage washes up on beaches. Kamilo Beach, in the U.S. state of Hawai'i, is littered with plastic bags and bottles carried in by the tide . The trash is dangerous to ocean life and reduces economic activity in the area. Tourism is Hawai'i’s largest industry . Polluted beaches discourage tourists from investing in the area’s hotels, restaurants, and recreational activities. Some cities incinerate , or burn, their garbage. Incinerating trash gets rid of it, but it can release dangerous heavy metals and chemicals into the air. So while trash incinerators can help with the problem of land pollution, they sometimes add to the problem of air pollution. Reducing Pollution Around the world, people and governments are making efforts to combat pollution. Recycling, for instance, is becoming more common. In recycling, trash is processed so its useful materials can be used again. Glass, aluminum cans, and many types of plastic can be melted and reused . Paper can be broken down and turned into new paper. Recycling reduces the amount of garbage that ends up in landfills, incinerators, and waterways. Austria and Switzerland have the highest recycling rates. These nations recycle between 50 and 60 percent of their garbage. The United States recycles about 30 percent of its garbage. Governments can combat pollution by passing laws that limit the amount and types of chemicals factories and agribusinesses are allowed to use. The smoke from coal-burning power plants can be filtered. People and businesses that illegally dump pollutants into the land, water, and air can be fined for millions of dollars. Some government programs, such as the Superfund program in the United States, can force polluters to clean up the sites they polluted. International agreements can also reduce pollution. The Kyoto Protocol , a United Nations agreement to limit the emission of greenhouse gases, has been signed by 191 countries. The United States, the world’s second-largest producer of greenhouse gases, did not sign the agreement. Other countries, such as China, the world’s largest producer of greenhouse gases, have not met their goals. Still, many gains have been made. In 1969, the Cuyahoga River, in the U.S. state of Ohio, was so clogged with oil and trash that it caught on fire. The fire helped spur the Clean Water Act of 1972. This law limited what pollutants could be released into water and set standards for how clean water should be. Today, the Cuyahoga River is much cleaner. Fish have returned to regions of the river where they once could not survive. But even as some rivers are becoming cleaner, others are becoming more polluted. As countries around the world become wealthier, some forms of pollution increase. Countries with growing economies usually need more power plants, which produce more pollutants. Reducing pollution requires environmental, political, and economic leadership. Developed nations must work to reduce and recycle their materials, while developing nations must work to strengthen their economies without destroying the environment. Developed and developing countries must work together toward the common goal of protecting the environment for future use.

Indoor Air Pollution The air inside your house can be polluted. Air and carpet cleaners, insect sprays, and cigarettes are all sources of indoor air pollution.

Light Pollution Light pollution is the excess amount of light in the night sky. Light pollution, also called photopollution, is almost always found in urban areas. Light pollution can disrupt ecosystems by confusing the distinction between night and day. Nocturnal animals, those that are active at night, may venture out during the day, while diurnal animals, which are active during daylight hours, may remain active well into the night. Feeding and sleep patterns may be confused. Light pollution also indicates an excess use of energy. The dark-sky movement is a campaign by people to reduce light pollution. This would reduce energy use, allow ecosystems to function more normally, and allow scientists and stargazers to observe the atmosphere.

Noise Pollution Noise pollution is the constant presence of loud, disruptive noises in an area. Usually, noise pollution is caused by construction or nearby transportation facilities, such as airports. Noise pollution is unpleasant, and can be dangerous. Some songbirds, such as robins, are unable to communicate or find food in the presence of heavy noise pollution. The sound waves produced by some noise pollutants can disrupt the sonar used by marine animals to communicate or locate food.

Essay on Problem of Pollution

Pollution is a grave problem that poses a significant threat to our environment, health, and the future of our planet. It occurs when harmful substances enter the air, water, or soil, causing damage to ecosystems and endangering all forms of life. In this essay, we will delve into the critical issue of pollution, examining its causes and effects and the urgent need for action to combat it.

Types of Pollution

There are several types of pollution, each with its own set of causes and consequences. Air pollution, for example, results from the release of harmful gases and particles into the atmosphere, often from vehicles and industrial activities. Water pollution occurs when pollutants contaminate rivers, lakes, and oceans, harming aquatic life and making water unsafe for human consumption. Soil pollution, on the other hand, affects the quality of the soil, making it less fertile and endangering our food supply.

Causes of Pollution

The causes of pollution are diverse, but many can be traced back to human activities. The burning of fossil fuels for energy production and transportation is a major contributor to air pollution, releasing harmful gases like carbon dioxide and sulfur dioxide. Irresponsible waste disposal and industrial discharges contaminate our water bodies, leading to water pollution. Additionally, the use of pesticides and chemicals in agriculture can result in soil pollution.

Effects on Health

Pollution has dire consequences for human health. Breathing in polluted air can lead to respiratory problems like asthma and bronchitis. Water pollution can cause waterborne diseases, affecting millions of people worldwide. Moreover, soil pollution can lead to contaminated crops, posing health risks when consumed. The health effects of pollution are particularly harmful to vulnerable populations, including children and the elderly.

Environmental Impact

The impact of pollution on the environment is extensive and devastating. Air pollution, for instance, contributes to global warming and climate change, leading to more extreme weather events. Water pollution harms aquatic ecosystems, leading to the decline of fish populations and the destruction of coral reefs. Soil pollution reduces soil fertility, affecting agricultural productivity and biodiversity.

Wildlife and Ecosystems

Pollution does not discriminate—it affects both humans and wildlife. Many animal species suffer due to habitat destruction caused by pollution. Additionally, toxic substances in water bodies can lead to the death of aquatic animals, disrupting food chains and ecosystems. Pollution also poses a threat to endangered species, pushing them closer to extinction.

Urgent Need for Action

The problem of pollution is urgent and requires immediate action. Governments, industries, and individuals must work together to reduce pollution levels and mitigate their effects. Transitioning to clean energy sources, implementing stricter environmental regulations, and promoting sustainable practices are crucial steps in combating pollution.

Education and Awareness

Education plays a vital role in addressing the problem of pollution. By raising awareness about the causes and consequences of pollution, we can empower individuals to make eco-friendly choices in their daily lives. Schools, communities, and organizations can organize campaigns and initiatives to educate people about pollution prevention and sustainable living.

Individual Responsibility

While governments and industries have a significant role to play, individual responsibility is also paramount. Simple actions like reducing energy consumption, recycling, and properly disposing of waste can make a difference. Each person can contribute to the reduction of pollution by making mindful choices that minimize their environmental footprint.

Conclusion of Essay on Problem of Pollution

In conclusion, the problem of pollution is a pressing issue that affects our health, the environment, and the well-being of future generations. We must acknowledge the causes and consequences of pollution and take immediate action to combat it. Through collective efforts, education, and individual responsibility, we can reduce pollution levels, preserve our planet’s natural beauty, and ensure a healthier, cleaner, and more sustainable future for all. The time to act is now, and together, we can make a difference in the fight against pollution.

Problem of Pollution Essay

Pollution is a global threat whose effects are currently being faced by all humankind as well as wildlife. The threat to wildlife is due to the pollution caused by humans. Here are a few sample essays on the “Problem of Pollution”.

100-Word Essay on the Problem of Pollution

The rise of pollution is a direct result of human greed only. The use of harmful pesticides and fertilisers to increase plant yield in the short term leads to barren and toxic land in the longer run. Huge industries dump their waste in rivers and oceans instead of recycling them to save the cost. People are reluctant to use public transport and thus millions of private vehicles are responsible for the huge amount of rise in air pollution as well as noise pollution. It is high time that we start taking action against the problem of pollution before it makes our whole earth unsafe to live in and a threat to mankind itself.

200-Word Essay on the Problem of Pollution

500-word essay on the problem of pollution, types of pollution.

Pollution is defined as the introduction of contamination, either a substance (solid, liquid, or gas) or any form of energy (heat, sound, or radioactivity) that causes an adverse change in the environment. The major kinds of pollution are air pollution, water pollution, land pollution, noise pollution, and light pollution. Pollution of all kinds has a negative and disastrous result on the environment, and human & animal life forms.

Harmful effects of Pollution

The issue of pollution has disturbed the smooth and continuous flow of nature, and now its adverse effects are causing catastrophe for us. Global warming and climate change are two direct results of air pollution that are responsible for floods, increases in Earth’s temperature, melting of glaciers, and even forest fires. The exploitation of natural resources by humans such as coal and petroleum and then the excessive use of them in producing electricity and vehicles are also contributing to it.

The government and institutions from all over the world should come together to fight against this problem of pollution. People should be made aware on an individual level of the basic rules of the 3Rs – Reduce, Reuse, and Recycle. This huge problem of pollution can only be tackled with the combined efforts of the government as well as individuals.

Pollution is a global threat, so our approach should be global too. If we all act together as global citizens, we have a huge chance of winning this battle against pollution. The problem of pollution needs a serious and well-planned step-by-step approach from the topmost global level to the individual.

Pollution has been broadly divided into five major categories. They are -

Air Pollution | The release of chemicals into the atmosphere, from the huge factories to the refrigerators installed in our homes, is defined as air pollution.

Common gaseous pollutants include carbon monoxide, sulphur dioxide, CFCs, and nitrogen oxides. The major causes of air pollution are burning fossil fuels, mining, and the release of harmful greenhouse gases into the atmosphere by industries and factories.

The effects of air pollution are quite disastrous and a threat to our survival -

Global warming

Increase in skin diseases, respiratory diseases, and even cancer.

Water Pollution | When toxic pollutants and chemicals are released into the water bodies such as lakes, rivers, and seas, it is called water pollution. It can be natural too, such as eutrophication, but the major culprits of water pollution are human activities only. Activities such as oil spills, dumping of inorganic waste, and disposal of effluents such as dye, and paint in water bodies are major causes of water pollution.

Land Pollution | Any undesirable change in natural, physical, or biological components in the land, especially the soil, is termed land pollution. The use of pesticides, plastics, and radioactive material is the leading cause of land pollution.

Land Pollution leads to a decrease in fertility in the soil and microbial population. It destroys soil and the flora and fauna depend on the soil.

Noise Pollution | Unwanted sound released in the atmosphere may create adverse effects and can cause damage to the environment, resulting in noise pollution. It can be caused by a variety of indoor and outdoor sources of high intensity such as loudspeakers, aerodromes, old vehicles, etc. Noise Pollution can lead to profound deafness, anxiety, tension, and heart problems.

Light Pollution | It is the presence of unwanted and excessive artificial light during the day or night. An estimated 80 percent of Earth’s population is affected by light pollution. Light pollution can result in sleep deprivation, headaches, and stress.

In India, The Environment (Protection) Act was passed in 1986 to provide a framework for the central government to execute a nationwide program for combating environmental pollution.

My Experience

I live in New Delhi. This city is considered as one of the most polluted cities in the world. The problem of air pollution is directly faced by me and millions of other residents. I was diagnosed with asthma and breathing problems a few years ago. Since then, air purifiers have been a must for living in my city. It saddens me to see how humanity is moving towards its own death by polluting nature.

To completely bring pollution on the back foot, apart from all the government and global programs, individual participation and awareness are most required. We, as human beings, should play our role against the problem of pollution by making small changes in our lives such as not using plastic bags, recycling bottles, turning off electrical appliances when not in use, etc.

When undesired elements, or pollutants, are present in the environment, it is said to be polluted. The environment is severely harmed by pollution, which poses a direct threat to it. Although the world has begun to understand the importance of addressing pollution if the planet and its biodiversity are to be conserved there is still a long way to go.

Everything that makes up the environment, including the air, water bodies, flora, and wildlife, is impacted by pollution in one way or another. There are four main types of pollution – Air Pollution, Water Pollution, Noise Pollution and Soil or Land Pollution . Additionally, pollution contributes to global issues including acid rain, global warming, and greenhouse gas consequences. A rise in the planet’s average surface temperature is referred to as global warming, and it causes starvation, floods, and droughts.

Environmental pollution has a wide-ranging impact. In addition to the current effects of pollution, a lack of effective pollution prevention measures also imperils the future of various species. The pollution is causing harm at a far faster rate than it can be healed. Reversing the environmental harm we have caused could take generations, and even then, it won’t be simple. It will require tight discipline and commitment to stop pollution.

The best ways feasible are being used by various nations to respond to these catastrophes. More efforts are being launched to raise public awareness about the dangers of pollution and the importance of preserving our ecosystem. Greener lifestyles are gaining popularity; examples include using wind and solar energy, new climate-friendly cars, and energy-efficient lighting.

Pollution is the term used to describe the entry of pollutants into the environment. Noise, water, and air pollution are only a few of the several types of pollution. There is a direct relationship between the rise of pollution levels and illnesses among people. Therefore, it is important for everyone to be knowledgeable about pollution, its impacts, and effective ways to eliminate it. Our environment needs a balanced combination of all components, just like our body requires a balanced diet. The environment is polluted by any substance that is present above that limit for example rise in the levels of nitrogen oxides and carbon dioxide in the atmosphere causes harm to human health due to poor air quality.

All forms of pollution, whether in the air, water, soil, or noise, have a negative impact on living things. Deadly diseases that are brought on by the contamination of soil, water, air, or sound affect organisms.

Among the most common disorders brought on by air pollution are acute lower respiratory infections in children, ischemic heart disease, stroke, lung cancer, chronic obstructive pulmonary disease (COPD), and lung cancer. Air pollution is a major contributor to a number of ailments in India, including strokes, bronchitis, heart attacks, lung diseases, cancer, and early mortality from heart disorders. The most pressing issue in the world now is global warming, which is caused by air pollution.

Around the world, poor drinking water quality is the reason behind 50% of child deaths and 80% of illnesses, including more than 50 different diseases. Water pollution causes diarrhoea, skin diseases, malnutrition, and even cancer, as well as other issues that are related to it.

Every day, noise pollution has an effect on millions of people. The most frequent result of this is noise-induced hearing loss (NIHL). Loud noises have the potential to cause stress, high blood pressure, heart disease, and sleep difficulties. Children in particular are prone to these health issues across the board in terms of age groups. Noise pollution is extremely harmful, and it’s especially deadlier for people with heart issues.

Use of the 3Rs, or reduce, reuse, and recycle, is the first step in reducing pollution. People should use air conditioners less since they generate noxious gases, such as ozone-depleting chlorofluorocarbons, which will minimise air pollution.

Reducing the number of vehicles on the road will also help to clean up the planet’s air. The more often cars are used, the more dangerous chemicals like sulphur dioxide, nitrogen oxides, carbon monoxide, and hydrocarbons that contribute to major air pollution are released into the atmosphere.

Increasing public awareness is a further means of reducing pollution on Earth. Through programmes like the “Go Green” campaign, which urges people to plant more trees and use recyclable materials in their daily lives, awareness can be raised about the significance of eliminating pollution on Earth. The “Earth Hour” is another globally recognised event that calls for everyone to turn off all lights for one hour in order to raise awareness of the significance of reducing electricity usage in order to minimise pollution on Earth.

The government’s obligation to maintain national laws is one way to reduce pollution on Earth. Offenders should be subject to harsh penalties, such as increased fines and longer prison terms, which will force them to reconsider their influence on the environment and serve as a message to those who are not currently involved but who might be in the future.

Earth Is Drowning in Plastic. Can an International Treaty Help?

A marine scientist discusses the problem of plastic pollution and her hopes for an international treaty to tackle it

By Nicola Jones & Knowable Magazine

The problem of plastic pollution grows greater with each passing year.

Our world is increasingly plastic. Back in the 1950s, humanity produced just 5 million metric tons of plastic per year; today it’s 400 million metric tons. Since plastic can take hundreds or thousands of years to biodegrade, pretty much all of it is still around, except for the roughly 20 percent that’s been burned. By some estimates, there are now eight gigatons of accumulated plastic on Earth — twice as much as the weight of all animal life.

Much of this plastic is still in use, in products like cars and homes, but a lot is junk; 40 percent of plastic production goes toward packaging that’s typically tossed after being used once. Some of our plastic waste is recycled, responsibly incinerated or properly landfilled, but tens of millions of tons are mismanaged annually — burned in open pits or left to pollute the environment. Plastic pollution has been found at the poles and the bottom of the ocean , in our clouds and soils , in human blood and mothers’ milk . If things keep going as they are, it is predicted that annual rates of plastic flowing into the sea will triple from 2016 to 2040.

The impacts are manifold. Debris can choke and tangle wildlife; even zooplankton can fill up on microplastics instead of food, altering how much oxygen is in the ocean. And some of the chemicals used in plastics — including additives that make plastics flexible or fire-resistant — can leach out into water, soil or our bodies. Some of these are carcinogenic or endocrine disruptors, capable of interfering with development or reproduction. The net impacts of our lifelong exposure to this chemical soup are hard to tease out, but one recent study concluded that it cost the United States $249 billion in extra health care in 2018.

Delegates are working now on the world’s first plastic pollution treaty , which is due to be completed by the end of this year. That treaty might cap plastic production, phase out problem chemicals and regulate how waste is managed — but how ambitious this treaty will be is yet to be seen. (See box.)

Imogen Napper, a marine science postdoc at the University of Plymouth in the United Kingdom who specializes in plastic pollution, is one of many scientists whose research is informing the treaty process. Her detective work has documented plastic pollution in surprising places and pointed to solutions that have made their way into government regulations around the world. Knowable Magazine spoke with her about the plastic problem and what we can all do about it. This conversation has been edited for length and clarity.

Why did you decide to focus on plastic pollution as a researcher?

I was lucky to grow up in a small seaside town in the southwest of the UK. I don’t remember any discussion about plastic pollution or beach cleanups when I was younger. But now, going back home, plastic pollution is one of the most obvious environmental challenges that we have, because it’s so visible.

I’m hoping that plastic pollution can be used as a gateway issue to other environmental concerns. Climate change , I’d argue, is a far bigger beast than plastic pollution. But for plastic pollution, we’ve got all the tools that we need — we’ve got potential solutions, and discussion happening now through the plastics treaty. We have that burning fire of desire to make a change. We can fix it.

You and many other researchers spend a lot of time documenting where plastic is in the wild, and how it gets there. Why is this so hard?

When it comes to microscopic pieces in, say, a soil or water sample, it takes a lot of grunt work. I have spent a lot of time looking under the microscope trying to identify, just from the look of it, whether something is cellulosic — coming from plants, like cotton — or plastic. You get a good eye for it. But it can be really tricky.

Nor is it easy to document the accumulation and distribution of bigger, macro-sized chunks of plastic. There are so many sources, leakage points and places where plastic is building up. In one of our studies, led by Emily Duncan at the University of Exeter, we put GPS tags in plastic bottles and tracked them thousands of kilometers down the Ganges River. That sort of work helps to improve scientific models.

The commonly used estimate is that about 8 million metric tons of macroplastic enter the ocean each year. We know a lot less about the land. Technology is getting far better, with remote sensing, drones and satellite imagery . That will be very useful in the next few years to help us accurately identify how much plastic is going into the environment.

A lot of plastic litter is single-use products that have been tossed aside: In the UK, one survey showed that more than half of plastic litter was beverage-related, including cups, lids and straws. But some sources are more surprising, like tiny pieces of plastic thrown up by tire wear on highways.

That was also surprising to me. It’s so obvious — it’s right in front of you — but often we just don’t consider it. Research has only really focused on tire wear in the last few years, but it’s predicted to be one of the biggest single sources of microplastics — it has been estimated to make up five to 10 percent of the plastic entering the ocean.

In our lab, we have done a lot of research looking at clothing. I’d say about 60 percent of our wardrobe contains plastic, like polyester, acrylic or a natural-synthetic blend. A big part of my PhD research was centered around building a washing machine lab, and I tested for the first time different fabrics to see how many fibers would come off in a typical wash .

We found that for acrylic it was the most, at 700,000 fibers per wash. For polyester-cotton blend, it was a lot less, around 130,000 fibers. This started discussions about how we might make clothes differently or change our washing machines. In France, by 2025 all new washing machines will have to come with a filter, which is exciting. It’ll be really interesting to see how that develops. Ideally, the filter should be reusable, so we’re not just making more potential rubbish. There are a lot of different options ; independent testing will be important.

Where does all this plastic wind up?

You could argue that plastic really is everywhere. We did some research that found plastic fibers just below the summit of Mount Everest . In some regions, plastic microfibers can go down the drain into the sewage treatment plants; the collected solids, called sewage sludge, is then treated and then often applied on agricultural land as fertilizer. There’s evidence that the chemicals in those plastics can then be absorbed into plants .

There are some surprising ecological effects, too. I have read that some plastic pieces, because of their dark colors, absorb heat, which means they’re contributing to melting snow and ice .

Yes. Plastic can also increase sand temperature, and this has been found in turtle nesting sites . And turtle sex is dependent on the temperature of the sand. So we might end up with a lot more female turtles.

What’s the best thing to do with plastic at the end of its life?

Landfill isn’t great, but it does contain and control waste when done right. Incineration has pros and cons; it gets rid of the plastic and can be used to make energy. A lot of small island developing states may use incineration because they haven’t got the space for landfill, but then it’s often open burning, which is not good for the planet or your health.

People often think that recycling is a golden solution. But recycling is not fully circular — the recycled plastic is often made into a polymer of worsening quality. At some point, it will not be recyclable. Recycling can also generate problematic microplastics. And if there isn’t a market for the recycled material , it can end up in landfill.

None of this gets rid of the core issue. It’s just delaying it. I’m a big believer of tackling the problem at its source. My supervisor, Richard Thompson, says plastic pollution is like an overfilling bath. We’re very good at mopping up the floor, but the bath keeps overflowing. What we need to do is turn off the tap.

Are there good alternatives to conventional plastic, like biodegradable or compostable plastics, or bioplastics that are made from plants rather than from fossil fuels?

We did some research on this. We did a study looking at biodegradable carrier bags : We buried them in the soil, we submerged them in the ocean, and we left them hanging outside for three years. The ones outside completely fragmented into tiny bits — the plastic didn’t disappear, it just got smaller. The ones in the soil and in the ocean could still hold a full bag of shopping.

Biodegradable plastics that are marketed today need to go into a really specific waste management facility with high moisture, high heat, maybe a certain pH, to disappear.

Many bioplastics used today — such as bio-polyethylene — are chemically the same as other plastics, just made from a different source. They’re made from plant carbon instead of from fossil fuel carbon, but they may behave exactly like all other plastic. If they’re still single use, is that any better?

There’s a lot of work going into alternative products , but we need to be careful that they’re actually better for our health and the environment.

How is the plastics treaty (see box) coming along?

It’s going to take a lot of discussion, and I will be delighted if it happens this year, but realistically, I think it is going to take a little bit more time. It is difficult to get nations to agree to firm action, because a lot of it comes down to money — both the money to be made from manufacturing plastic, and the money it costs to deal with waste.

This is an amazing opportunity that we have, where globally we can have a unified decision on how to protect our planet. The treaty needs to be ambitious, it needs to be specific, and it needs to be binding.

Is it reasonable to think that some plastics might be banned?

Legislation has already banned some plastics and additives in some countries or regions. Our lab quantified microbeads in beauty products : We found that 3 million microbeads could be in a bottle of facial scrub. So there can be thousands in a squirt on your hand. We took this research, we published it, and then one day I came in to work and I had so many emails in my inbox from journalists. It was making quite a stir. And there were campaigns like “ Beat the microbead ,” because consumers didn’t want to wash their faces with plastic.

So the consumers started to boycott the products, then industry voluntarily removed microbeads and showcased that information in their own marketing. And then governments around the world started to ban microbeads in facial scrubs.

Research is all about providing information. And then, with that information, people can take it forward and make a change. I feel very privileged to be in a position that I can be part of that.

If you were in charge, would you ban specific plastics or chemicals?

I’d flip the question on its head and ask: What would I keep? We don’t need all the plastic we make. And instead of using a big chemical cocktail of additives that we don’t know anything about, let’s just have a list of the chemicals that we can use.

When I started my PhD, I wrongly thought that plastic was evil. Plastics are incredibly useful and can solve other environmental and health problems. Plastic can keep our food fresh, and food waste is a huge problem. During the pandemic, it helped to keep people safe. It is lightweight, so products need less energy for transport.

But let’s think, right from when we’re designing it, how can we make sure it’s sustainable? Often, we’re not thinking about that right at the beginning, we’re thinking about it far down at the end of its life.

Treaty timeline

In 2022, 175 nations at the United Nations Environment Assembly agreed to draft a legally binding treaty against plastic pollution by 2024. That work is now underway, but progress has been slow, leaving observers wondering if it will be completed as planned at the meeting in Busan, South Korea, this December — and, if so, how ambitious it will be.

In 2023, delegates released an updated, 70-page pre- draft outlining issues to be tackled, along with a handful of options for how to address them. The issues span the full lifecycle of plastics — from their creation, including the greenhouse gases emitted during their production, through to the uses of plastics (including as single-use products and microbeads), to recycling and waste management. Topics such as tax schemes and pots of money for capacity-building in poorer nations get their share of coverage too.

The options for each issue range from hard to soft: Even the options for the stated objective of the treaty, for example, span from “to end plastic pollution” to the much gentler “to protect human health and the environment from plastic pollution.”

Many observers at the treaty’s third meeting , in Nairobi in November 2023, said that agreement on firm solutions seemed far away, with delegates from some fossil fuel-rich nations, including Saudi Arabia, pushing against hard production caps. Analysts have noted that as the planet cracks down on burning fossil fuels for energy, the oil industry has increasingly focused on plastic production as a profitable market.

On the other hand, a group of nations led by Norway and Rwanda — called the “ high ambition coalition ” — is pressing for strong action. “It’s a bit of a roller coaster,” says marine biologist Richard Thompson, Imogen Napper’s PhD supervisor at the University of Plymouth; he attended the treaty meeting as one of the coordinators of the independent Scientists’ Coalition for an Effective Plastics Treaty . “There’s great support and traction in one direction — and half an hour later, things seem to turn.”

One scientific model shows that it will take an extremely ambitious bundle of policies to drive mismanaged waste down. By this model, for example, cutting mismanaged plastic waste by 85 percent by 2050 would require implementing a 90 percent reduction in single-use packaging, a cap on primary plastic production at 2025 levels, and a mandate that at least 40 percent of plastics be recycled and that more than 40 percent of new products be made from recycled content — along with heavy taxes and more than $200 billion of investments in global waste infrastructure.

Scientists are also thinking hard about the treaty’s proposed list of polymers and chemicals of concern , which could be used to guide bans by specific dates, or just to encourage regulation. Such a list could include, for example, polyvinyl chloride (PVC) and polystyrene — often called “the toxic two” by environmental groups — alongside additives including phthalates (which are often used to make PVC more flexible and some of which are endocrine disrupters).

Many analysts and concerned observers would like to see the plastic treaty modeled after the Montreal Protocol on Substances That Deplete the Ozone Layer, which in 1986 famously phased out specific chemicals like chlorofluorocarbons with hard, time-targeted commitments. But it might, alternatively, be modeled more like the Paris Agreement on Climate Change, which allows nations to determine their own targets for action. That might be easier to agree upon, but less ambitious.

“It’s difficult to get all these nations to agree on all the nuts and bolts,” says Thompson. It remains to be seen how things will pan out at the next meeting , scheduled for Ottawa, Canada, this April.

Thompson remains hopeful for a big change in how society uses plastic. “It’s so cheap we can use it for a few seconds before throwing it away. That’s the problem,” he says. But, he adds, “a problem we can solve.”

Air Pollution: Everything You Need to Know

How smog, soot, greenhouse gases, and other top air pollutants are affecting the planet—and your health.

What is air pollution?

What causes air pollution, effects of air pollution, air pollution in the united states, air pollution and environmental justice, controlling air pollution, how to help reduce air pollution, how to protect your health.

Air pollution refers to the release of pollutants into the air—pollutants that are detrimental to human health and the planet as a whole. According to the World Health Organization (WHO) , each year, indoor and outdoor air pollution is responsible for nearly seven million deaths around the globe. Ninety-nine percent of human beings currently breathe air that exceeds the WHO’s guideline limits for pollutants, with those living in low- and middle-income countries suffering the most. In the United States, the Clean Air Act , established in 1970, authorizes the U.S. Environmental Protection Agency (EPA) to safeguard public health by regulating the emissions of these harmful air pollutants.

“Most air pollution comes from energy use and production,” says John Walke , director of the Clean Air team at NRDC. Driving a car on gasoline, heating a home with oil, running a power plant on fracked gas : In each case, a fossil fuel is burned and harmful chemicals and gases are released into the air.

“We’ve made progress over the last 50 years in improving air quality in the United States, thanks to the Clean Air Act. But climate change will make it harder in the future to meet pollution standards, which are designed to protect health ,” says Walke.

Air pollution is now the world’s fourth-largest risk factor for early death. According to the 2020 State of Global Air report —which summarizes the latest scientific understanding of air pollution around the world—4.5 million deaths were linked to outdoor air pollution exposures in 2019, and another 2.2 million deaths were caused by indoor air pollution. The world’s most populous countries, China and India, continue to bear the highest burdens of disease.

“Despite improvements in reducing global average mortality rates from air pollution, this report also serves as a sobering reminder that the climate crisis threatens to worsen air pollution problems significantly,” explains Vijay Limaye , senior scientist in NRDC’s Science Office. Smog, for instance, is intensified by increased heat, forming when the weather is warmer and there’s more ultraviolet radiation. In addition, climate change increases the production of allergenic air pollutants, including mold (thanks to damp conditions caused by extreme weather and increased flooding) and pollen (due to a longer pollen season). “Climate change–fueled droughts and dry conditions are also setting the stage for dangerous wildfires,” adds Limaye. “ Wildfire smoke can linger for days and pollute the air with particulate matter hundreds of miles downwind.”

The effects of air pollution on the human body vary, depending on the type of pollutant, the length and level of exposure, and other factors, including a person’s individual health risks and the cumulative impacts of multiple pollutants or stressors.

Smog and soot

These are the two most prevalent types of air pollution. Smog (sometimes referred to as ground-level ozone) occurs when emissions from combusting fossil fuels react with sunlight. Soot—a type of particulate matter —is made up of tiny particles of chemicals, soil, smoke, dust, or allergens that are carried in the air. The sources of smog and soot are similar. “Both come from cars and trucks, factories, power plants, incinerators, engines, generally anything that combusts fossil fuels such as coal, gasoline, or natural gas,” Walke says.

Smog can irritate the eyes and throat and also damage the lungs, especially those of children, senior citizens, and people who work or exercise outdoors. It’s even worse for people who have asthma or allergies; these extra pollutants can intensify their symptoms and trigger asthma attacks. The tiniest airborne particles in soot are especially dangerous because they can penetrate the lungs and bloodstream and worsen bronchitis, lead to heart attacks, and even hasten death. In 2020, a report from Harvard’s T.H. Chan School of Public Health showed that COVID-19 mortality rates were higher in areas with more particulate matter pollution than in areas with even slightly less, showing a correlation between the virus’s deadliness and long-term exposure to air pollution.

These findings also illuminate an important environmental justice issue . Because highways and polluting facilities have historically been sited in or next to low-income neighborhoods and communities of color, the negative effects of this pollution have been disproportionately experienced by the people who live in these communities.

Hazardous air pollutants

A number of air pollutants pose severe health risks and can sometimes be fatal, even in small amounts. Almost 200 of them are regulated by law; some of the most common are mercury, lead , dioxins, and benzene. “These are also most often emitted during gas or coal combustion, incineration, or—in the case of benzene—found in gasoline,” Walke says. Benzene, classified as a carcinogen by the EPA, can cause eye, skin, and lung irritation in the short term and blood disorders in the long term. Dioxins, more typically found in food but also present in small amounts in the air, is another carcinogen that can affect the liver in the short term and harm the immune, nervous, and endocrine systems, as well as reproductive functions. Mercury attacks the central nervous system. In large amounts, lead can damage children’s brains and kidneys, and even minimal exposure can affect children’s IQ and ability to learn.

Another category of toxic compounds, polycyclic aromatic hydrocarbons (PAHs), are by-products of traffic exhaust and wildfire smoke. In large amounts, they have been linked to eye and lung irritation, blood and liver issues, and even cancer. In one study , the children of mothers exposed to PAHs during pregnancy showed slower brain-processing speeds and more pronounced symptoms of ADHD.

Greenhouse gases

While these climate pollutants don’t have the direct or immediate impacts on the human body associated with other air pollutants, like smog or hazardous chemicals, they are still harmful to our health. By trapping the earth’s heat in the atmosphere, greenhouse gases lead to warmer temperatures, which in turn lead to the hallmarks of climate change: rising sea levels, more extreme weather, heat-related deaths, and the increased transmission of infectious diseases. In 2021, carbon dioxide accounted for roughly 79 percent of the country’s total greenhouse gas emissions, and methane made up more than 11 percent. “Carbon dioxide comes from combusting fossil fuels, and methane comes from natural and industrial sources, including large amounts that are released during oil and gas drilling,” Walke says. “We emit far larger amounts of carbon dioxide, but methane is significantly more potent, so it’s also very destructive.”

Another class of greenhouse gases, hydrofluorocarbons (HFCs) , are thousands of times more powerful than carbon dioxide in their ability to trap heat. In October 2016, more than 140 countries signed the Kigali Agreement to reduce the use of these chemicals—which are found in air conditioners and refrigerators—and develop greener alternatives over time. (The United States officially signed onto the Kigali Agreement in 2022.)

Pollen and mold

Mold and allergens from trees, weeds, and grass are also carried in the air, are exacerbated by climate change, and can be hazardous to health. Though they aren’t regulated, they can be considered a form of air pollution. “When homes, schools, or businesses get water damage, mold can grow and produce allergenic airborne pollutants,” says Kim Knowlton, professor of environmental health sciences at Columbia University and a former NRDC scientist. “ Mold exposure can precipitate asthma attacks or an allergic response, and some molds can even produce toxins that would be dangerous for anyone to inhale.”

Pollen allergies are worsening because of climate change . “Lab and field studies are showing that pollen-producing plants—especially ragweed—grow larger and produce more pollen when you increase the amount of carbon dioxide that they grow in,” Knowlton says. “Climate change also extends the pollen production season, and some studies are beginning to suggest that ragweed pollen itself might be becoming a more potent allergen.” If so, more people will suffer runny noses, fevers, itchy eyes, and other symptoms. “And for people with allergies and asthma, pollen peaks can precipitate asthma attacks, which are far more serious and can be life-threatening.”

More than one in three U.S. residents—120 million people—live in counties with unhealthy levels of air pollution, according to the 2023 State of the Air report by the American Lung Association (ALA). Since the annual report was first published, in 2000, its findings have shown how the Clean Air Act has been able to reduce harmful emissions from transportation, power plants, and manufacturing.

Recent findings, however, reflect how climate change–fueled wildfires and extreme heat are adding to the challenges of protecting public health. The latest report—which focuses on ozone, year-round particle pollution, and short-term particle pollution—also finds that people of color are 61 percent more likely than white people to live in a county with a failing grade in at least one of those categories, and three times more likely to live in a county that fails in all three.

In rankings for each of the three pollution categories covered by the ALA report, California cities occupy the top three slots (i.e., were highest in pollution), despite progress that the Golden State has made in reducing air pollution emissions in the past half century. At the other end of the spectrum, these cities consistently rank among the country’s best for air quality: Burlington, Vermont; Honolulu; and Wilmington, North Carolina.

No one wants to live next door to an incinerator, oil refinery, port, toxic waste dump, or other polluting site. Yet millions of people around the world do, and this puts them at a much higher risk for respiratory disease, cardiovascular disease, neurological damage, cancer, and death. In the United States, people of color are 1.5 times more likely than whites to live in areas with poor air quality, according to the ALA.

Historically, racist zoning policies and discriminatory lending practices known as redlining have combined to keep polluting industries and car-choked highways away from white neighborhoods and have turned communities of color—especially low-income and working-class communities of color—into sacrifice zones, where residents are forced to breathe dirty air and suffer the many health problems associated with it. In addition to the increased health risks that come from living in such places, the polluted air can economically harm residents in the form of missed workdays and higher medical costs.

Environmental racism isn't limited to cities and industrial areas. Outdoor laborers, including the estimated three million migrant and seasonal farmworkers in the United States, are among the most vulnerable to air pollution—and they’re also among the least equipped, politically, to pressure employers and lawmakers to affirm their right to breathe clean air.

Recently, cumulative impact mapping , which uses data on environmental conditions and demographics, has been able to show how some communities are overburdened with layers of issues, like high levels of poverty, unemployment, and pollution. Tools like the Environmental Justice Screening Method and the EPA’s EJScreen provide evidence of what many environmental justice communities have been explaining for decades: that we need land use and public health reforms to ensure that vulnerable areas are not overburdened and that the people who need resources the most are receiving them.

In the United States, the Clean Air Act has been a crucial tool for reducing air pollution since its passage in 1970, although fossil fuel interests aided by industry-friendly lawmakers have frequently attempted to weaken its many protections. Ensuring that this bedrock environmental law remains intact and properly enforced will always be key to maintaining and improving our air quality.

But the best, most effective way to control air pollution is to speed up our transition to cleaner fuels and industrial processes. By switching over to renewable energy sources (such as wind and solar power), maximizing fuel efficiency in our vehicles, and replacing more and more of our gasoline-powered cars and trucks with electric versions, we'll be limiting air pollution at its source while also curbing the global warming that heightens so many of its worst health impacts.

And what about the economic costs of controlling air pollution? According to a report on the Clean Air Act commissioned by NRDC, the annual benefits of cleaner air are up to 32 times greater than the cost of clean air regulations. Those benefits include up to 370,000 avoided premature deaths, 189,000 fewer hospital admissions for cardiac and respiratory illnesses, and net economic benefits of up to $3.8 trillion for the U.S. economy every year.

“The less gasoline we burn, the better we’re doing to reduce air pollution and the harmful effects of climate change,” Walke explains. “Make good choices about transportation. When you can, ride a bike, walk, or take public transportation. For driving, choose a car that gets better miles per gallon of gas or buy an electric car .” You can also investigate your power provider options—you may be able to request that your electricity be supplied by wind or solar. Buying your food locally cuts down on the fossil fuels burned in trucking or flying food in from across the world. And most important: “Support leaders who push for clean air and water and responsible steps on climate change,” Walke says.

“When you see in the news or hear on the weather report that pollution levels are high, it may be useful to limit the time when children go outside or you go for a jog,” Walke says. Generally, ozone levels tend to be lower in the morning.
If you exercise outside, stay as far as you can from heavily trafficked roads. Then shower and wash your clothes to remove fine particles.
The air may look clear, but that doesn’t mean it’s pollution free. Utilize tools like the EPA’s air pollution monitor, AirNow , to get the latest conditions. If the air quality is bad, stay inside with the windows closed.
If you live or work in an area that’s prone to wildfires, stay away from the harmful smoke as much as you’re able. Consider keeping a small stock of masks to wear when conditions are poor. The most ideal masks for smoke particles will be labelled “NIOSH” (which stands for National Institute for Occupational Safety and Health) and have either “N95” or “P100” printed on it.
If you’re using an air conditioner while outdoor pollution conditions are bad, use the recirculating setting to limit the amount of polluted air that gets inside.

Long Essay on Pollution

Pollution is a complex and multifaceted environmental issue that poses a significant threat to the sustainability of our planet. It is the introduction of contaminants into the natural environment, resulting in adverse changes that affect ecosystems, biodiversity, and human health. Pollution can take various forms, including air pollution, water pollution, soil pollution, noise pollution, and light pollution, each with its unique set of challenges and consequences.

Sources of Pollution

The sources of pollution are diverse and often interconnected. Industrial activities, urbanization, transportation, agriculture, and improper waste management contribute significantly to the release of pollutants into the environment. Industrial processes emit a variety of pollutants, including greenhouse gases, particulate matter, and toxic chemicals, which can have detrimental effects on air quality and contribute to climate change.

Vehicle emissions, stemming from the burning of fossil fuels, release pollutants such as carbon monoxide, nitrogen oxides, and particulate matter into the atmosphere, contributing to air pollution and respiratory diseases. Improper disposal of waste, both solid and liquid, contaminates water bodies and soil, posing threats to aquatic life, plant health, and food safety.

Agricultural practices, including the use of pesticides and fertilizers, contribute to soil and water pollution, affecting both the environment and human health. Deforestation and urbanization disrupt natural ecosystems, leading to habitat loss and the displacement of wildlife. Noise pollution, resulting from human activities such as traffic, construction, and industrial processes, can have adverse effects on human health, causing stress, sleep disturbances, and hearing loss.

Consequences of Pollution

The consequences of pollution are severe and far-reaching. Air pollution is a major contributor to respiratory diseases, including asthma and chronic obstructive pulmonary disease (COPD). Long-term exposure to air pollutants such as particulate matter and nitrogen dioxide has been linked to cardiovascular diseases and adverse pregnancy outcomes.

Water pollution poses threats to aquatic life and human health. Contaminated water sources can lead to the spread of waterborne diseases, affecting millions of people globally. Soil pollution affects plant growth and food safety, as pollutants like pesticides and heavy metals accumulate in the soil and enter the food chain.

Noise pollution can have physiological and psychological effects, causing stress, sleep disturbances, and an increased risk of cardiovascular diseases. Light pollution disrupts natural ecosystems and interferes with the behavior of nocturnal animals, affecting their reproductive patterns and migration.

Global Impact

Pollution is not confined to local or regional boundaries; it has a global impact. Greenhouse gas emissions, primarily from the burning of fossil fuels, contribute to global warming and climate change. The rise in global temperatures leads to melting ice caps, rising sea levels, and extreme weather events, posing threats to unsafe ecosystems and communities.

The pollution of oceans with plastic waste has become a global crisis, with millions of tons of plastic entering the oceans annually. This not only harms marine life but also affects human health, as microplastics enter the food chain through seafood consumption.

Loss of biodiversity is another consequence of pollution, as ecosystems are disrupted and species face habitat destruction and pollution-induced stress. The decline of pollinators, such as bees, due to exposure to pesticides, has implications for agriculture and food security.

Addressing Pollution

Addressing pollution requires a comprehensive and collaborative approach at individual, community, and governmental levels. Individuals can contribute by adopting sustainable practices in their daily lives, such as reducing energy consumption, using eco-friendly products, and practicing responsible waste disposal.

Communities can organize clean-up initiatives, promote recycling programs, and raise awareness about the importance of environmental conservation. Educational institutions play a crucial role in fostering environmental awareness and sustainability practices among students.

Governments must enact and enforce stringent environmental regulations to curb pollution. Incentives for industries to adopt cleaner technologies, invest in renewable energy sources, and implement sustainable waste management practices are essential. International cooperation is crucial to address global environmental challenges, with countries working together to reduce greenhouse gas emissions, combat plastic pollution, and protect biodiversity.

Essay on Pollution in 800 Words

Pollution, the presence of unwanted substances known as pollutants in the environment, poses an immediate and severe threat to the delicate balance of our ecosystems. The recognition of the urgent need to address pollution is essential if we are to preserve the Earth and its biodiversity. This essay explores the various facets of pollution, its types, and the impact it has on major Indian cities such as Delhi, Noida, Ghaziabad, Lucknow, and Varanasi.

What is Pollution?

Pollution occurs when external compounds, primarily generated by human activities, enter the environment as unwanted entities known as pollutants. These pollutants cause significant harm to the environment, affecting water bodies, air, flora, and fauna. The consequences of pollution extend globally, contributing to phenomena like the greenhouse gas effect, global warming, and acid rain.

Effects of Pollution on Major Indian Cities

Imagine bustling cities in India, like Delhi or Varanasi, filled with life and energy. However, there’s a problem casting a shadow over this vibrancy – pollution. In this exploration, we’re going to look at how pollution affects the air, water, and soil in cities such as Delhi, Noida, Ghaziabad, Lucknow, and Varanasi. The goal is to understand the challenges these cities face and why it’s so important for everyone to work together to tackle pollution and ensure a healthier future.

Pollution Level in Delhi

Delhi, the National Capital Territory, faces a dire situation in terms of air quality index (AQI). According to the World Health Organization, Delhi ranks lowest among 1650 major cities worldwide. The air quality, especially during the winter months from October to December, rapidly deteriorates, reaching hazardous levels.

The AQI for Delhi remains moderate (101-200) from January to September but spikes during winter, often surpassing 500. Particulate Matter (PM2.5 and PM10) levels soar well beyond safe limits, primarily due to factors such as vehicular emissions, industrial activities, and the traditional practice of burning paddy crop roots in neighboring states.

Pollution Level in Noida

Noida, bordering Delhi in western Uttar Pradesh, faces similar challenges with poor air quality. Intensive construction activities, heavy vehicular pollution, and cold winter air contribute to the formation of a thick smog, impacting the Air Quality Index. The PM levels in Noida compete with Delhi, often reaching hazardous levels during the winter months.

Pollution Level in Ghaziabad

Ghaziabad frequently tops the list of North Indian cities with the worst AQI and pollution levels. Industrial pollution and waste burning are major contributors to Ghaziabad’s poor air quality. Located on the outskirts of the city, industries emit dense smoke, exacerbating pollution. The PM10 levels in Ghaziabad often surpass permissible limits, reaching alarming levels, especially during festivals like Diwali.

Pollution Level in Lucknow

Lucknow, the capital of Uttar Pradesh, experiences fluctuating AQI levels, ranging from moderate to poor. While not as severe as Delhi NCR, the air quality in Lucknow is still alarming, demanding concrete action. The quantity of suspended Particulate Matter has increased significantly in residential areas, posing health risks. The city’s air contains fine PM2.5 particles, reaching hazardous concentrations.

Pollution Level in Varanasi

Varanasi, the ancient pilgrimage city and the parliamentary constituency of Indian Prime Minister Narendra Modi, faces environmental challenges due to ongoing construction activities. Varanasi’s AQI is ranked third on the World Health Organization’s list of the fifteen most polluted cities globally. The ongoing construction work contributes to a decline in air quality, with AQI reaching up to 300, falling in the “Poor” category. Particulate Matter, especially PM2.5, poses health risks to the city’s residents.

The impacts of pollution are profound, impacting ecosystems, biodiversity, and the well-being of humans. Prolonged exposure to air pollutants is associated with cardiovascular diseases, while contaminated water sources contribute to the spread of waterborne diseases. Soil pollution poses risks to food safety, and noise pollution leads to stress and hearing loss. Additionally, light pollution disrupts wildlife behavior.

Importantly, pollution transcends local boundaries; its consequences are felt globally. Greenhouse gas emissions contribute significantly to global warming, causing adverse effects on climate patterns. The accumulation of plastic waste in oceans not only harms marine life but also infiltrates the food chain, posing threats to human health. Furthermore, pollution-induced stress and habitat destruction contribute to the loss of biodiversity, impacting ecosystems on a global scale.

Stringent environmental regulations need to be implemented and enforced by governments to combat pollution effectively. Offering incentives to industries for adopting cleaner technologies, investing in renewable energy sources, and practicing sustainable waste management is vital. International cooperation is essential to tackle global environmental challenges, with countries collaborating to decrease greenhouse gas emissions, combat plastic pollution, and safeguard biodiversity.

Pollution remains a pressing issue affecting major Indian cities, with severe implications for the environment and public health. The need for immediate and concerted efforts to address pollution is evident, as evidenced by the deteriorating air quality in cities like Delhi, Noida, Ghaziabad, Lucknow, and Varanasi. It is imperative that governments, industries, and individuals collaborate to adopt sustainable practices, enforce regulations, and invest in technologies that mitigate the environmental impact. Only through collective action can we hope to mitigate the menace of pollution and ensure a healthier and sustainable future for our planet.

Pollution is a critical environmental issue that demands urgent attention and concerted efforts at local, national, and global levels. The consequences of pollution are profound, affecting ecosystems, biodiversity, and human health. It is imperative that individuals, communities, industries, and governments work together to adopt sustainable practices, enforce regulations, and invest in technologies that minimize the environmental impact.

The battle against pollution requires a shift in mindset, where environmental sustainability becomes a priority in decision-making processes. By addressing pollution, we not only protect the health of our planet but also ensure a better quality of life for current and future generations. It is a collective responsibility to preserve the beauty and diversity of our natural environment and create a sustainable and harmonious coexistence between human activities and the ecosystems that support life on Earth.

Water Pollution and How it Harms the Environment

Global pollution is a problem. Pollution can spread to remote areas where no one lives, despite the fact that urban areas are typically more polluted than the countryside. Air pollution, water pollution, and land pollution are the three main categories of pollution. Some contaminated water has a terrible smell, a muddy appearance, and floating trash. Some contaminated water appears clean, but it contains dangerous substances that you can't see or smell.

Together, developed and developing nations must fight to conserve the environment for present and future generations. Today, we dig deep into the subject of Water Pollution. This article can be an introduction to water pollution for kids as we will read many things such as the causes of water pollution further in the article.

What is Water Pollution?

Water contamination occurs when pollutants pollute water sources and make the water unfit for use in drinking, cooking, cleaning, swimming, and other activities. Chemicals, garbage, bacteria, and parasites are examples of pollutants. Water is eventually damaged by all types of pollution. Lakes and oceans become contaminated by air pollution. Land contamination may contaminate an underground stream, a river, and ultimately the ocean. As a result, trash thrown on an empty lot can eventually contaminate a water source.

(Image will be uploaded soon)

Water Pollution

The water cycle, called the hydrological cycle, involves the following steps:

Evaporation- Because of the sun's heat, the water bodies such as oceans, lakes, seas etc., get heated up, and water evaporates in the air, forming water vapours.

Transpiration- Like evaporation, the plants and trees also lose water from them which goes to the atmosphere. This process is called transpiration.

Condensation- As the water evaporates, it starts to become cool because of the cold atmosphere in the air and because of this cooling down of water leads to the formation of clouds.

Precipitation- Because of the high movements of the wings, the clouds start to collide and then fall back to the earth’s surface in the form of rain. Sometimes they also fall back in the form of snow, hail, sleet etc., depending upon the temperature.

Runoff or Infiltration- After precipitation, the water either flows to the water bodies called runoff or is absorbed into the soil, called infiltration.

Causes of Water Pollution

There are many reasons for water pollution. Some of the reasons are directly affected by water pollution and some indirectly. Many factories and industries are dumping contaminated water, chemicals, and heavy metals into major waterways as a result of direct water pollution.

One more reason for water pollution is the use of modern techniques in farms. Farmers apply nutrients such as phosphorus, nitrogen, and potassium in the form of chemical fertilizers, manure, and sludge. It causes farms to discharge large quantities of agrochemicals, organic matter, and saline drainage into water bodies. It indirectly affects water pollution.

Pollutants can be of various types such as organic, inorganic, radioactive etc. Water pollutants are discharged either from one point from pipes, channels etc., which are called point sources or from various other sources. They can be agricultural areas, industries etc., called dispersed sources.

Some of the major forms of water pollutants are as follows:

Sewage- Domestic sewage from homes contains various forms of pathogens that threaten the human body. Sewage treatment reduces the risk of pathogens, but this risk is not eliminated.

Domestic sewage majorly contains nitrates and phosphates, and excess of these substances allows the algae to grow on the surface of water bodies. Due to this, the clean water bodies become nutrient-rich water body and then slowly, the oxygen level of water bodies reduces. This is called eutrophication or cultural eutrophication (if this step rapidly takes place by the activities of humans). This leads to the early death of water bodies.

Toxins- The industrial or factory wastes that are not disposed of properly and contain chemicals such as mercury and lead are disposed of in the water bodies making the bodies toxic, radioactive, explosive and cancerous.

Sediments- Sediments are the result of soil erosion that is formed in the water bodies. These sediments imbalances the water bodies ecologically. They also interfere in the reproductive cycle of various aquatic animals living in the water.

Thermal pollution- Water bodies get polluted because of heat, and excess heat reduces the oxygen level of the water bodies. Some of the species of fish cannot live in such water bodies with very low oxygen levels. The disposal of cold waters from the power plants leads to increased thermal pollution in the water bodies.

Petroleum oil pollution- The runoff of oil into the water bodies, either accidentally as happened in 2010 in the Gulf of Mexico, or intentionally, leads to an increase in water pollution.

As water is an important element of human health, polluted water directly affects the human body. Water pollution causes various diseases like typhoid, cholera, hepatitis, cancer, etc. Water pollution damages the plants and aquatic animals present in the river by reducing the oxygen content from the water. Polluted water washes the essential nutrients which plants need out of the soil and also leaves large amounts of aluminium in the soil, which can be harmful to plants.

Wastewater and sewage are a by-product of daily life and thus produced by each household through various activities like using soap, toilets, and detergents. Such sewage contains chemicals and bacteria which are harmful to human life and environmental health. Water pollution also leads to an imbalance in our ecosystem. Lastly, it also affects the food chain as the toxins in the water bodies are consumed by aquatic animals like fish, crabs etc., and then humans consume those animals forming turmoil.

Sometimes our tradition also becomes a cause for water pollution. Some people throw the statues of deities, flowers, pots, and ashes in rivers.

There are various standards to define water quality standards. Water meant for swimming may not be clean enough for drinking, or water meant for bathing may not be good for cooking. Therefore, there are different water standards for defined:

Stream standards- Standards that define streams, lakes, oceans or seas based on their maximum use.

Effluent standards- Define the specific standards for the level of contaminants or effluents allowed during the final discharge of those into the water bodies.

Drinking water standards- Define the level of contamination allowed in water that will be supplied for drinking or cooking in the domestic areas.

Different countries regulate their water quality standards through different acts and amendments.

While many of the solutions for water pollution need to be applied on a broader macro-level for that individual, companies, and communities can have a significant and responsible impact on the water quality. Companies, factories have to dispose of leftover chemicals and containers properly as per the product instructions. Farmers also have to reduce the use of nitrates and phosphates from fertilizers, pesticides, and contamination of groundwater.

The Swachh Bharat Mission of the government had led to reduced groundwater contamination. Under the Namami Ganga program, the government has initiated several major projects to clean Ganga. Along with all these steps, conservation of water is the very basic and important step towards water conservation and should be followed globally, treatment of sewage before their disposal in the water bodies and using environment-friendly products that do not form toxins when dissolved in water. These are some small steps that have to be taken into consideration by every human being.

As we all know, “Water is life’s matter and matrix, mother and medium. There is no life without water.” We have to save water. We must keep the water clean. If everyone will follow their responsibility against water to protect it from getting polluted then it will be easy to get clean and healthy drinking water. Clean water is a must for us and our kids' present, future, and healthy environment.

We cannot just live with contaminated waters filled with toxins and no oxygen. We cannot see our wildlife being destroyed and therefore, immediate steps have to be taken by groups of people to first clean the already contaminated water bodies and then keep a check on all the surrounding water bodies. Small steps by every individual can make a huge difference in controlling water pollution.

Water Pollution Prevention

Conserve Water

Our first priority should be to conserve water. Water wasting could be a big problem for the entire world, but we are just now becoming aware of it.

Sewage Treatment

Cleaning up waste materials before disposing of them in waterways reduces pollution on a large scale. By lowering its dangerous elements, this wastewater will be used in other sectors or in agriculture.

Usage of Eco-Friendly Materials

We will reduce the amount of pollution produced by choosing soluble products that do not alter to become pollutants.

Water contamination is the discharge of pollutants into the water body, where they dissolve, are suspended, are deposited on the bottom, and collect to the point where they hinder the aquatic ecosystem's ability to function. Water contamination is brought on by toxic compounds that easily dissolve and combine with it and come from factories, municipalities, and farms.

Healthy ecosystems depend on a complex network of organisms, including animals, plants, bacteria, and fungi, all of which interact with one another either directly or indirectly. In this article, we read about water pollution, its causes and prevention. With this, we have come to the end of our article, in case of any other doubts, feel free to ask in the comments.

FAQs on Water Pollution Essay

1. What are the effects of water pollution?

Water pollution has a great impact on human health. Water pollution kills. It's been recorded that in 2015 nearly 1.8 million people died because of water pollution. People with low income are exposed to contaminated water coming out from the industries. Presence of disease causing pathogens in drinking water are the major cause of illness which includes cholera, giardia, and typhoid. Water pollution not only affects human health but also our environment by causing algal bloom in a lake or marine environment. Water pollution also causes eutrophication which suffocates plants and animals and thus causes dead zones. Chemicals and heavy metals from industrial and municipal wastewater contaminate waterways and harm aquatic life.

2. What are the causes of Water pollution?

Water being a universal solvent is vulnerable to pollution as it dissolves more substances than any other liquid on earth. Therefore, water is easily polluted. Toxic substances from farms, towns, and factories readily dissolve into water and mix with it, resulting in water pollution. Agricultural pollution is one of the major causes of contamination in rivers and streams. The use of excessive fertilizers, pesticides, and animal waste from farms and livestock operations lets the rain wash the nutrients and pathogens—such as bacteria and viruses—into our waterways. The other major cause of water pollution is used water, termed as wastewater which comes from our sinks, showers, toilets and from commercial, industrial, and agricultural activities. It's been reported that the world's 80% wastewater flows back into the environment without being treated or reused. Oil spills and radioactive waste also cause water pollution to a great extent.

3. How to prevent water pollution?

It is important to keep our water bodies clean so we can take the following preventive measures to prevent from water pollution:

Chemicals like bleach, paint, paint thinner, ammonia, and many chemicals are becoming a serious problem. Dumping toxic chemicals down the drain or flushing them down the toilet can cause water pollution. Thus, proper disposal is important. Also, household chemicals need to be recycled.

Avoid buying products that contain persistent and dangerous chemicals. Buying non-toxic cleaners and biodegradable cleaners and pesticides cut down on water pollution.

Prevent from pouring fats or greasy substances down the drain as it might clog the drain resulting in the dumping of waste into yards or basement which can contaminate the local water bodies.

4. What is the role of medical institutions in polluting the water?

Pharmaceutical pollution affects aquatic life and thus there is a need to take preventive measures. Consumers are responsible for winding up pharmaceutical and personal care products in lakes, rivers, and streams. There's a lot of unused and expired medication that can potentially get into the water if not disposed of properly.

5. What are the major kinds of pollution?

The three main types of pollution are air pollution, water pollution or soil pollution. Some artificial pollution is also there, such as noise pollution. Factors leading to such pollution include:

Air Pollution: Industrial emissions, fires, traffic and transportation, burning of chemical waste, etc.

Water Pollution: No proper sewage disposal, pesticides in farms leaking into water bodies, industrial waste dumped into water bodies, etc.

Soil Pollution: Oil spills, acid rains, irresponsible disposal of trash, chemical waste, etc.

Noise Pollution: Honking of horns, construction activities, loud parties, etc.

Ocean floor a 'reservoir' of plastic pollution, study finds

Ocean floor a 'reservoir' of plastic pollution, world-first study finds

New research from CSIRO, Australia's national science agency, and the University of Toronto in Canada, estimates up to 11 million metric tons of plastic pollution is sitting on the ocean floor. The article, "Plastics in the deep sea—A global estimate of the ocean floor reservoir ," was published in Deep Sea Research Part I: Oceanographic Research Papers.

Every minute, a garbage truck's worth of plastic enters the ocean. With plastic use expected to double by 2040, understanding how and where it travels is crucial to protecting marine ecosystems and wildlife.

Dr. Denise Hardesty, Senior Research Scientist with CSIRO, said this is the first estimate of how much plastic waste ends up on the ocean floor , where it accumulates before being broken down into smaller pieces and mixed into ocean sediment.

"We know that millions of tons of plastic waste enter our oceans every year but what we didn't know is how much of this pollution ends up on our ocean floor," Dr. Hardesty said.

"We discovered that the ocean floor has become a resting place, or reservoir, for most plastic pollution, with between 3 to 11 million tons of plastic estimated to be sinking to the ocean floor.

"While there has been a previous estimate of microplastics on the seafloor, this research looks at larger items, from nets and cups to plastic bags and everything in between."

Alice Zhu, a Ph.D. Candidate from the University of Toronto who led the study, said the estimate of plastic pollution on the ocean floor could be up to 100 times more than the amount of plastic floating on the ocean's surface based on recent estimates.

"The ocean surface is a temporary resting place of plastic so it is expected that if we can stop plastic entering our oceans, the amount would be reduced," Zhu said.

"However, our research found that plastic will continue to end up in the deep ocean, which becomes a permanent resting place or sink for marine plastic pollution."

Scientific data was used to build two predictive models to estimate the amount and distribution of plastic on the ocean floor—one based on data from remote operated vehicles (ROVs) and the other from bottom trawls.

Using ROV data, 3 to 11 million metric tons of plastic pollution is estimated to reside on the ocean floor.

The ROV results also reveal that plastic mass clusters around continents—approximately half (46%) of the predicted plastic mass on the global ocean floor resides above 200 m depth. The ocean depths, from 200 m to as deep as 11,000 m contains the remainder of predicted plastic mass (54%).

Although inland and coastal seas cover much less surface area than oceans (11% vs. 56% out of the entire Earth's area), these areas are predicted to hold as much plastic mass as does the rest of the ocean floor.

"These findings help to fill a longstanding knowledge gap on the behavior of plastic in the marine environment ," Zhu said.

"Understanding the driving forces behind the transport and accumulation of plastic in the deep ocean will help to inform source reduction and environmental remediation efforts, thereby reducing the risks that plastic pollution may pose to marine life."

This research is part of CSIRO's Ending Plastic Waste Mission , which aims to change the way we make, use, recycle and dispose of plastic.

Climate change, pollution, and collapsing biodiversity are damaging our immune systems

Improving the environment offers effective and fast-acting protection

4 min. read ▪ Published April 4

The ecosystems we live in don’t work the way they used to — and that’s bad for our health. Climate change, pollution, and falling biodiversity are all damaging our immune systems. The lack of positive environmental exposures to build the strength of our immune systems, and the increasing negative exposures which attack those systems, are combining to cause a dramatic rise in immune-mediated diseases like asthma and cancer.

Measures to protect against this could have a very powerful return on investment: an estimated $1 spent on climate change mitigation saves $3 on healthcare costs. A global team of researchers—including John Balmes , professor emeritus of environmental health sciences—writing in Frontiers in Science call for urgent action to safeguard a healthy future.

“Increased emission of pollutants has led to fundamental changes in our environment,” said first author, Dr. Ioana Agache of the Transilvania University of Brașov, Romania, and co-chair of the European Academy of Allergy & Clinical Immunology’s Guidelines on Environmental Science for Allergy and Asthma. “From an evolutionary perspective, the immune system is constantly molded to respond to the environment and maintain health; however, the recent changes have been too rapid for our immune system to adequately adapt.”

Planetary health is preventive health

The effects of anthropogenic climate change and pollution on our bodies are complex, but a crucial factor is the damage they inflict on our immune systems. These develop over time in response to environmental factors—positive or negative.

Being exposed to toxic pollutants damages the epithelial barrier, leading to immune dysregulation, which leads to autoimmune disorders and cancer. Meanwhile, a lack of exposure to suitable biodiversity means that immune systems are not properly calibrated, driving up the rates of allergies and asthma. Rising temperatures alter pollen seasons, so that the season starts earlier and lasts longer, and that the pollen released provokes stronger allergic reactions, increasing the prevalence and severity of pollen allergies.

Climate change is increasing the frequency and severity of natural disasters, with significant secondary health impacts. Higher temperatures increase the probability of wildfires, which release air particulate matter and other pollutants. These pollutants can spread for hundreds of kilometers and linger long after the fire has been put out, contributing to immune dysregulation and worsening a range of health issues. They also contribute to global warming, increasing the probability of future wildfires.

“As a physician-scientist, I have seen first-hand how air pollution from wildfires affect respiratory health,” said Professor Kari Nadeau of Harvard University, senior author. “I have also seen the impact of lengthening pollen season and increased pollen allergenicity on allergies and asthma.”

These impacts fall most heavily on the most vulnerable members of society. An inadequate diet, a lack of access to the natural environment, and a lack of safe, clean housing all increase the chances of developing immune-mediated diseases. Measures to fight the health impacts of climate change must explicitly include equity, to ensure a global recovery from a global threat.

Adapt and mitigate

The scientists call for a two-pronged approach: adapt to climate change by improving diets, housing, access to nature and agricultural practices, and mitigate its impact by cutting emissions, improving air quality, and fostering environmental biodiversity. To take effective action, however, we need data to inform new measures and track the progress of existing ones.

Agache and colleagues focus on three key data initiatives: biomarkers, economic models, and data science techniques. Biomarkers will track immune-mediated diseases like cancer caused by air pollution, while new economic models can quantify the harm done by climate change and the cost benefits of remedial action. Meanwhile, data scientists are developing new approaches for unraveling the multifactorial influences of our altered environment on our immune systems.

“The impacts of climate change are complex, with multifaceted effects,” said author Dr. Vanitha Sampath of Harvard University. “AI can assist with the convergence and analysis of disparate datasets to identify threats and inform remediation.”

“It is clear that planetary health and human health are interconnected,” concluded Nadeau. “I hope by sharing current knowledge on how our actions adversely affect planetary and human health, and some of the actions we can take to adapt to and mitigate these changes, we can empower individual citizens as well as local, national, and international organizations to work towards a better future.”

Noise Pollution: Effects, Causes, and Potential Solutions Essay

Introduction, effects of noise pollution, causes of noise pollution, potential solutions, works cited.

Some people may frown upon it, while others might nod their heads with their whole-hearted smile on their faces – no matter which category you belong to, as a person, especially as a person who must live in a neighborhood, the quality of the neighborhood has always been an important issue to be concerned about when you are looking for a place to live. For most people, the quality of the neighborhood is at the center of attention even more than the quality of the living spaces. As much as a good neighborhood can positively affect our mental and physical health and improve the quality of our lives, a bad neighborhood can increase anxiety among neighbors and can decrease their lives’ efficiency. Although there exist lots of problems that need to be solved in every neighborhood, noise pollution, no matter whether this noise is made by your neighbors or the surrounding environment, is with no doubt the most important issue in almost all neighborhoods. First, it is essential to investigate the reasons why noise is an important issue in almost every neighborhood and then explore the main contributing causes of the noise problem.

The first and also foremost reason why noise is an important issue in neighborhoods lies in the inevitable fact that noise pollution can have negative effects on our physical health. Living in a noisy area can affect the quality of people’s sleep, daily activities, and even general physical health factors. According to the International Program on Chemical Safety, “an adverse effect of noise is defined as a change in the morphology and physiology of organism that results in an impairment of functional capacity, or an impairment of capacity to compensate for additional stress or increases the susceptibility of the organism to harmful effects of other environmental influences” (Siano). Environmental noise exposure is responsible for a range of health effects, including increased risk of ischemic heart disease as well as sleep disturbance, cognitive impairment among children, annoyance, stress-related mental health risks, and tinnitus. This noise pollution becomes more important when we look at the noise level in residential neighbors where people spend most of their time.

For instance, “the health risks caused by noise pollution in high income European countries account for a loss of 1-1.6 million disability adjusted life years (DALYs) – a standard measure of healthy years of life lost to illness, disability, or early death” (Siano). Also, according to the World Health Organization (WHO), “noise pollution is one of the most dangerous environmental threats to health” (IBERDROLA). Moreover, according to the European Environmental Agency (EEA), “noise is responsible for 16,600 premature deaths and more than 72,000 hospitalizations every year in Europe alone” (IBERDROLA). Not only noise pollution can cause health issues for human, but it has a devastating impact on animals as well. According to the National Park Services (NPS) in the United States, “noise pollution has an enormous environmental impact and does serious damages to wildlife” (IBERDROLA). Most of the experts say that noise pollution can interfere with breeding cycles and rearing, and it is even hastening the extinction of some animal species. Therefore, noise pollution can not only affect mental health, but it can also affect our physical health.

Another reason, which is as important as the preceding one, if not more, is that noisy neighborhoods can substantively affect the efficiency of people’s work and their daily life activities. In the present day, the amount of noise in a living neighborhood becomes even more important since most of the people are forced to work from home due to the rules that companies made for their employees during the pandemic. To elucidate, the noisier a neighborhood is, the harder it becomes to concentrate on the activities that neighbors do, especially for the employees who work from home. The lower efficiency of activities will result in the lower efficient people in society. Moreover, the lower efficient people in society become more anxious and depressed as they see their activity outputs. Based on the report of the IKO Community Management survey, “48 percent of all survey takers said noise is number one complaint among the people who live in a neighborhood in large cities, whether this noise is from raucous late-night parties or opposite sleep schedules that result in one neighbor waking up the other” (IKO Community Management). As an illustration of the effect of noise pollution in the community that I live in, we always see struggling between the people who work at home during the day and the teenagers who play loud music and have parties at their apartment. Once, our neighbor, Larry, who is a programmer, complained to the community management office about George, a young boy who invites his friend to their apartment any time of the day to play loud music and laugh loudly. Larry told me, “it is important that people like George be aware of the rights of other people who live in the same area with them” (Pileggi). Therefore, noise pollution can affect our mental concentration level and efficiency at work.

After understanding the effects of noise on the neighbors, it is highly essential to explore the main contributing causes of noise. In comparison with ancient times when there were not many sources causing noise, these days, multiple different causes of noise exist. These causes can range from natural environment causes to human-generated causes. Although nature can make noises caused by animals and natural effects, human-generated noises are usually more dangerous and annoying. From a personal perspective, the most important three causes of noise that are also generated by humans are traffic and transportation noise, construction sites, and nightlife, though noise can come from a variety of other places as well.

Among these three sources of noise, I believe that the first and the most important cause of the noise is traffic and transportation noise. Without a doubt, we all live in homes that are close to at least one street or one alley. Living close to streets or alleys will cause being affected by the noise that is generated by passing cars. Moreover, some homes are close to bus stations or railroads, which means that people who live in these apartments suffer from louder noises generated by these huge public transportation facilities. According to the IBERDROLA, “a car horn produces 90 dB of noise and a bus produces 100 dB of noise.” On the basis of the World Health Organization’s (WHO) definition of noise, if we consider noise above 65 dB as noise pollution, this generated transportation noise can have a negative effect on our health. To be precise, noise becomes harmful when it exceeds 75 dB, and it will become painful if it is above 120 dB.

According to WHO, “it is recommended that noise levels to be kept below 65 dB during the day and 30 dB during nighttime” (WHO). A worse case is living close to the rail yard, as neighbors of the rail yard suffer from a higher level of noise pollution. Based on the interview that has been done about pros and cons of living close to a major rail yard, the interviewees felt that despite the fact that “the rail yard had a positive reputation and was highly valued for the jobs and economic growth it provides, it was also perceived, however, as a major contributor to the surrounding air quality as well as the noise pollution” (Spencer-Hwang). Several participants believed that “living in such close proximity to the rail yard had caused ailments in family, friends, and neighbors, as well as themselves” (Spencer-Hwang). Moreover, transportation noise can cause health-related issues, as previously discussed ones. According to the National Institute of Environmental Health Sciences, Clark et al. 2017 found “an increasing risk of diabetes with increasing exposure to transportation noise, but not with increasing exposure to traffic-related air pollutions.” In their study, noise pollution was independently associated with the incidence of diabetes in adult residents of metropolitan Vancouver, British Columbia (Clark). Therefore, transportation noise is not only unacceptable for most of the neighbors, but it is also risky for our health.

As the second source of noise, which is not as common as the first resource, we can consider construction. You may have experienced construction noise, even in the early morning, that affected your sleep quality and caused you to wake up because of this construction noise. Although not all the neighbors are close to construction zones and construction noise is not a common cause of the noise, building, car park construction, and road and pavement resurfacing generate an even greater amount of noise, with noise level even higher than transportation. As an example, according to IBERDROLA, “a pneumatic drill produces 110 dB noise,” which is higher than the noise that is generated by car horns and buses. Whether self-inflicted or common, everyday living noise can cause temporary or permanent deafness. When one is around noise for long periods of time, the risk of deafness is increased. “Construction noise has become the second most serious acoustic pollution in many cities, which could cause significant health damage and social costs. In addition, housing renovation and construction noise, which has rarely been investigated before, is a significant covariate of a wide range of mental health symptoms” (Ma). Specifically, as big cities are experiencing rapid urbanization processes, there are numerous ongoing construction projects that have led to an increase in environmental complaints, and construction noise has become a serious problem in the majority of big cities. For example, among people at higher risk of health problems caused by construction noise, “construction workers are at increased risk for being hearing impaired” (Cunningham). Therefore, construction as the second cause of the noise can result in serious mental and physical health problems as well.

The third cause of the noise is related to the nightlife. Humans have been created to live in social groups naturally. That is why all of us spend most of our time and socialize with our friends and family. However, sometimes this socialization can affect other people, especially if gatherings and socialization are generating loud noise and we are not paying attention to the others living close to us. Especially, a person who lives close to bars, restaurants, and clubs will feel noise that is generated by socialization and gatherings much more. According to IBERDROLA, “bars, restaurants, and terraces that spill outside when the weather is good can produce more than 100 dB noise. This includes noise from pubs and clubs”. According to Peplow et al., “sustained exposure to noise in areas close to public places also has been correlated with cognitive impairment and behavioral problems in children, as well as the more obvious hearing damage and sleep deprivation”. The European Environment Agency (EAA) has blamed “900 thousand cases of high blood pressure (hypertension), 43 thousand hospital admissions and 10 thousand cases of premature deaths a year in Europe on noise”. As a real example, I talked to our neighbor, Mr. Smith, about the reason of his high blood pressure. He told me that “the doctor told me that the main reason of my high blood pressure is living in the busiest part of the Santa Monica area. To decrease my blood pressure, the doctor recommended my wife and me to move to a suburb area”. Therefore, living close to the places that are designed specifically for nightlife can increase the risk of being affected by noise pollution.

Having scrutinized the issue, although people’s ideas vary on different points of the spectrum regarding the noise pollution issue in a neighborhood, I strongly believe that noise pollution is the first and most important issue that should be solved because of its destructive effects on mental and physical health. Although there exist many causes for noise pollution, I believe that transportation noise as the first and the most important cause, construction, and night life are the three most important causes of noise pollution. Hence, I think the explanation that I have provided above in favor of the destructive effects and the main causes of noise pollution are much stronger.

After finding out that all types of noise in living areas have an immeasurably negative impact on people’s health, work efficiency, and daily life activities, I see that the potential solutions to the problem of noise pollution are to either control its level by the government or allow people to use various techniques in order to decrease the level of noise independently. However, as the government cannot apply effective measures to all areas where people live, citizens’ individual measures will be more efficient.

It goes without saying that noise pollution has already become an international problem as almost all big cities across the globe face it. In general, the most common measures aimed to reduce the level of noise include the limitation of noisy leisure activities, especially at night, the use of bicycles instead of cars, environmental education, and the insulation of houses with noise-absorbing materials (IBERDROLA). As a matter of fact, governmental policies may ensure noise control and correct control management by area protection and sustainable building construction. For instance, the United States Environmental Protection Agency established the Office of Noise Abatement and Control (ONAC) under the Clean Air Act to study noise pollution and investigate its impact on the public health and people’s welfare (EPA). Since 1972, ONAC had been operating “to coordinate federal monitoring and regulation of noise at its source and facilitate informed policy-making at the state and local levels” (APHA).

The Office’s scope was expanded in 1978 by Congress that passed the Quiet Communities Act, including research funding and public health education dedicated to noise pollution (APHA). In general, ONAC created model noise ordinances, issued standards for local governments, and promulgated guidance documents in accordance with recommended or already existing exposure levels. In general, the governmental response includes appropriate planning policies and the introduction of the standards of sustainable construction in order to reduce the level of noise from the external environment in living buildings. In addition, the level of noise in residential buildings should be reduced as well according to the Building Regulations Approved Document E (Simonsen).

At the same time, governmental control cannot be regarded as a highly efficient measure. First of all, in 1981, the Administration decided that all issues related to noise pollution should be monitored by state and local governments (EPA). That is why, due to funding limitations, ONAC was closed. As a result, since 1986, no standards, regulations, or rules have been promulgated to limit sources of noise in electronics, appliances, industry, recreational items, or machinery (APHA). In addition, contemporary measures are not fully efficient due to their limited scope. In other words, only such territories as city parks, areas of natural interest, and new parts of the city may be protected (IBERDROLA). As a result, the majority of districts, especially old ones with established infrastructure, will be left without any changes. In addition, the idea of the construction of houses with the use of noise-absorbing materials is relevant only for new buildings. Thus, old buildings will be unprotected, and the level of noise in them will remain the same. Consequently, people who live in old districts with established infrastructure will suffer from the same levels of noise until they solve this issue by themselves.

That is why private measures that aim to reduce noise pollution for individuals and families who apply them are more efficient in comparison with policies that cannot affect all people. In other words, citizens may apply multiple useful, cost-effective techniques in order to reduce noise pollution in their apartments by themselves. The measures include the installation of acoustic wall panels, window shutters, or noise-blocking doors, placing furniture strategically, and turning off electrical appliances that constantly produce noise as well (JosTec). Noise cancelling headphones or earplugs may serve as a short-term solution in the case of construction work. Due to them, people will have a good sleep at night. Moreover, such design elements as wall hangings and carpets or rugs help reduce the level of noise. In addition, planting bushes and trees around the house by community members will reduce noise pollution and improve air quality as well. All these techniques may be defined as an excellent alternative for all people living in big cities, especially for those ones who cannot afford to move to another area protected from noise pollution.

NC State professor Angela Allen is training students to conduct water quality testing and monitoring through the Environmental Resource Clinic Student Training Program.

Drinking water is essential to human health, from regulating the body’s temperature to eliminating toxins. But when water becomes polluted, it can cause serious problems — from gastrointestinal illnesses to cancer.

NC State professor Angela Allen launched the Environmental Resource Clinic Student Training Program to train undergraduate and graduate students to identify and address drinking water quality issues.

“Students are trained to engage with communities and provide technical support for real-world water quality challenges as part of their education,” said Allen, an assistant teaching professor in the Department of Forestry and Environmental Resources.

The Environmental Resource Clinic Student Training Program is open to all NC State students interested in learning about water quality monitoring and research. More than 20 students have participated in research, mentorship and community outreach opportunities so far.

All students complete online safety training before learning to use a variety of tools to determine water quality parameters and pollution. They also learn to communicate their findings with communities and other stakeholders.

“We work immediately with communities. They are the backbone of the work we do,” Allen said. “Students are introduced to these stakeholders so that they can get a sense of the importance of what we do and why we do it.”

Much of the work completed so far has focused on addressing ongoing water quality challenges in the Walnut Creek watershed, specifically in the historic neighborhoods of Rochester Heights and Biltmore Hills.

The predominantly African-American neighborhoods often experience flooding as polluted stormwater from downtown Raleigh and Interstate 40 flows into Little Rock Creek, a tributary of the Walnut Creek watershed.

Walnut Creek feeds into the Neuse River, which provides drinking water for thousands of North Carolinians. It has long been adversely affected by sedimentation and bacterial contamination.

Local organizations, government agencies and other stakeholders, including NC State researchers, have worked together over the past decade to mitigate flooding and pollution in southeast Raleigh.

Allen’s involvement began with a request from Stacie Hagwood, then manager of Walnut Creek Wetland Park, for water quality monitoring. Her program has since expanded to include collaborations with Partners for Environmental Justice, the North Carolina Department of Environmental Quality, among others.

“Working to characterize water quality in an area that has been disproportionately impacted by urban development gives our students an opportunity to positively contribute to the health and well-being of our community,” Allen said.

She added, “We are led by the needs of those in our community, and having knowledge about their concerns allows us to provide the needed resources to arrive at meaningful solutions.”

Allen and her students have not only monitored water quality, but they’ve also partnered with collaborators to develop funding proposals for Walnut Creek improvement projects and to participate in outreach activities.

Andrea Putri, a senior majoring in environmental technology and management at NC State, has participated in the Environmental Resource Clinic Student Training Program since summer 2023 as an undergraduate research assistant.

Putri said the program has provided her with valuable skills and knowledge that will contribute to future success. It has not only improved her ability to think critically and collaborate with others, but it has also improved her ability to manage her time appropriately and communicate science to the public.

“My participation in the program has been a rewarding experience,” Putri said. “I can say it has helped me gain insight into the topics of environmental justice, water quality, leadership skills, and how to become a lifelong learner.”

She added that her participation in the program has even helped her to further articulate her career goals. “My initial plan after graduation was to pursue a career in water and environmental management. But after this experience, I have also started thinking about continuing my academic studies by getting a master’s degree or doctorate degree.”

Recently, the North Carolina Source Water Collaborative awarded Allen the 2024 Source Water Protection Education Award for her contributions through the Environmental Resource Clinic Student Training Program.

The Source Water Protection Award acknowledges individuals and/or groups that demonstrate innovative, proactive, and collaborative solutions to protect North Carolina’s drinking water and the watersheds that support it.

Going forward, Allen is seeking funding to continue the program in order to meet increased demand. The program has seen exponential growth since its launch, with more and more students wanting to participate.

“Students yearn for more experiences outside the classroom and want to learn about research,” Allen said. “This program does just that.”

3. problems students are facing at public k-12 schools.

We asked teachers about how students are doing at their school. Overall, many teachers hold negative views about students’ academic performance and behavior.

48% say the academic performance of most students at their school is fair or poor; a third say it’s good and only 17% say it’s excellent or very good.
49% say students’ behavior at their school is fair or poor; 35% say it’s good and 13% rate it as excellent or very good.

Teachers in elementary, middle and high schools give similar answers when asked about students’ academic performance. But when it comes to students’ behavior, elementary and middle school teachers are more likely than high school teachers to say it’s fair or poor (51% and 54%, respectively, vs. 43%).

A horizontal stacked bar chart showing that many teachers hold negative views about students’ academic performance and behavior.

Teachers from high-poverty schools are more likely than those in medium- and low-poverty schools to say the academic performance and behavior of most students at their school are fair or poor.

The differences between high- and low-poverty schools are particularly striking. Most teachers from high-poverty schools say the academic performance (73%) and behavior (64%) of most students at their school are fair or poor. Much smaller shares of teachers from low-poverty schools say the same (27% for academic performance and 37% for behavior).

In turn, teachers from low-poverty schools are far more likely than those from high-poverty schools to say the academic performance and behavior of most students at their school are excellent or very good.

Lasting impact of the COVID-19 pandemic

A horizontal stacked bar chart showing that most teachers say the pandemic has had a lasting negative impact on students’ behavior, academic performance and emotional well-being.

Among those who have been teaching for at least a year, about eight-in-ten teachers say the lasting impact of the pandemic on students’ behavior, academic performance and emotional well-being has been very or somewhat negative. This includes about a third or more saying that the lasting impact has been very negative in each area.

Shares ranging from 11% to 15% of teachers say the pandemic has had no lasting impact on these aspects of students’ lives, or that the impact has been neither positive nor negative. Only about 5% say that the pandemic has had a positive lasting impact on these things.

A smaller majority of teachers (55%) say the pandemic has had a negative impact on the way parents interact with teachers, with 18% saying its lasting impact has been very negative.

These results are mostly consistent across teachers of different grade levels and school poverty levels.

Major problems at school

When we asked teachers about a range of problems that may affect students who attend their school, the following issues top the list:

Poverty (53% say this is a major problem at their school)
Chronic absenteeism – that is, students missing a substantial number of school days (49%)
Anxiety and depression (48%)

One-in-five say bullying is a major problem among students at their school. Smaller shares of teachers point to drug use (14%), school fights (12%), alcohol use (4%) and gangs (3%).

Differences by school level

A bar chart showing that high school teachers more likely to say chronic absenteeism, anxiety and depression are major problems.

Similar shares of teachers across grade levels say poverty is a major problem at their school, but other problems are more common in middle or high schools:

61% of high school teachers say chronic absenteeism is a major problem at their school, compared with 43% of elementary school teachers and 46% of middle school teachers.
69% of high school teachers and 57% of middle school teachers say anxiety and depression are a major problem, compared with 29% of elementary school teachers.
34% of middle school teachers say bullying is a major problem, compared with 13% of elementary school teachers and 21% of high school teachers.

Not surprisingly, drug use, school fights, alcohol use and gangs are more likely to be viewed as major problems by secondary school teachers than by those teaching in elementary schools.

Differences by poverty level

A dot plot showing that majorities of teachers in medium- and high-poverty schools say chronic absenteeism is a major problem.

Teachers’ views on problems students face at their school also vary by school poverty level.

Majorities of teachers in high- and medium-poverty schools say chronic absenteeism is a major problem where they teach (66% and 58%, respectively). A much smaller share of teachers in low-poverty schools say this (34%).

Bullying, school fights and gangs are viewed as major problems by larger shares of teachers in high-poverty schools than in medium- and low-poverty schools.

When it comes to anxiety and depression, a slightly larger share of teachers in low-poverty schools (51%) than in high-poverty schools (44%) say these are a major problem among students where they teach.

Discipline practices

About two-thirds of teachers (66%) say that the current discipline practices at their school are very or somewhat mild – including 27% who say they’re very mild. Only 2% say the discipline practices at their school are very or somewhat harsh, while 31% say they are neither harsh nor mild.

We also asked teachers about the amount of influence different groups have when it comes to determining discipline practices at their school.

67% say teachers themselves don’t have enough influence. Very few (2%) say teachers have too much influence, and 29% say their influence is about right.

A diverging bar chart showing that two-thirds of teachers say they don’t have enough influence over discipline practices at their school.

31% of teachers say school administrators don’t have enough influence, 22% say they have too much, and 45% say their influence is about right.
On balance, teachers are more likely to say parents, their state government and the local school board have too much influence rather than not enough influence in determining discipline practices at their school. Still, substantial shares say these groups have about the right amount of influence.

Teachers from low- and medium-poverty schools (46% each) are more likely than those in high-poverty schools (36%) to say parents have too much influence over discipline practices.

In turn, teachers from high-poverty schools (34%) are more likely than those from low- and medium-poverty schools (17% and 18%, respectively) to say that parents don’t have enough influence.

The Problem With Saying ‘Sex Assigned at Birth’

A black and white photo of newborns in bassinets in the hospital.

By Alex Byrne and Carole K. Hooven

Mr. Byrne is a philosopher and the author of “Trouble With Gender: Sex Facts, Gender Fictions.” Ms. Hooven is an evolutionary biologist and the author of “T: The Story of Testosterone, the Hormone That Dominates and Divides Us.”

As you may have noticed, “sex” is out, and “sex assigned at birth” is in. Instead of asking for a person’s sex, some medical and camp forms these days ask for “sex assigned at birth” or “assigned sex” (often in addition to gender identity). The American Medical Association and the American Psychological Association endorse this terminology; its use has also exploded in academic articles. The Cleveland Clinic’s online glossary of diseases and conditions tells us that the “inability to achieve or maintain an erection” is a symptom of sexual dysfunction, not in “males,” but in “people assigned male at birth.”

This trend began around a decade ago, part of an increasing emphasis in society on emotional comfort and insulation from offense — what some have called “ safetyism .” “Sex” is now often seen as a biased or insensitive word because it may fail to reflect how people identify themselves. One reason for the adoption of “assigned sex,” therefore, is that it supplies respectful euphemisms, softening what to some nonbinary and transgender people, among others, can feel like a harsh biological reality. Saying that someone was “assigned female at birth” is taken to be an indirect and more polite way of communicating that the person is biologically female. The terminology can also function to signal solidarity with trans and nonbinary people, as well as convey the radical idea that our traditional understanding of sex is outdated.

The shift to “sex assigned at birth” may be well intentioned, but it is not progress. We are not against politeness or expressions of solidarity, but “sex assigned at birth” can confuse people and creates doubt about a biological fact when there shouldn’t be any. Nor is the phrase called for because our traditional understanding of sex needs correcting — it doesn’t.

This matters because sex matters. Sex is a fundamental biological feature with significant consequences for our species, so there are costs to encouraging misconceptions about it.

Sex matters for health, safety and social policy and interacts in complicated ways with culture. Women are nearly twice as likely as men to experience harmful side effects from drugs, a problem that may be ameliorated by reducing drug doses for females. Males, meanwhile, are more likely to die from Covid-19 and cancer, and commit the vast majority of homicides and sexual assaults . We aren’t suggesting that “assigned sex” will increase the death toll. However, terminology about important matters should be as clear as possible.

More generally, the interaction between sex and human culture is crucial to understanding psychological and physical differences between boys and girls, men and women. We cannot have such understanding unless we know what sex is, which means having the linguistic tools necessary to discuss it. The Associated Press cautions journalists that describing women as “female” may be objectionable because “it can be seen as emphasizing biology,” but sometimes biology is highly relevant. The heated debate about transgender women participating in female sports is an example ; whatever view one takes on the matter, biologically driven athletic differences between the sexes are real.

When influential organizations and individuals promote “sex assigned at birth,” they are encouraging a culture in which citizens can be shamed for using words like “sex,” “male” and “female” that are familiar to everyone in society, as well as necessary to discuss the implications of sex. This is not the usual kind of censoriousness, which discourages the public endorsement of certain opinions. It is more subtle, repressing the very vocabulary needed to discuss the opinions in the first place.

A proponent of the new language may object, arguing that sex is not being avoided, but merely addressed and described with greater empathy. The introduction of euphemisms to ease uncomfortable associations with old words happens all the time — for instance “plus sized” as a replacement for “overweight.” Admittedly, the effects may be short-lived , because euphemisms themselves often become offensive, and indeed “larger-bodied” is now often preferred to “plus sized.” But what’s the harm? No one gets confused, and the euphemisms allow us to express extra sensitivity. Some see “sex assigned at birth” in the same positive light: It’s a way of talking about sex that is gender-affirming and inclusive .

The problem is that “sex assigned at birth”— unlike “larger-bodied”— is very misleading. Saying that someone was “assigned female at birth” suggests that the person’s sex is at best a matter of educated guesswork. “Assigned” can connote arbitrariness — as in “assigned classroom seating” — and so “sex assigned at birth” can also suggest that there is no objective reality behind “male” and “female,” no biological categories to which the words refer.

Contrary to what we might assume, avoiding “sex” doesn’t serve the cause of inclusivity: not speaking plainly about males and females is patronizing. We sometimes sugarcoat the biological facts for children, but competent adults deserve straight talk. Nor are circumlocutions needed to secure personal protections and rights, including transgender rights. In the Supreme Court’s Bostock v. Clayton County decision in 2020, which outlawed workplace discrimination against gay and transgender people, Justice Neil Gorsuch used “sex,” not “sex assigned at birth.”

A more radical proponent of “assigned sex” will object that the very idea of sex as a biological fact is suspect. According to this view — associated with the French philosopher Michel Foucault and, more recently, the American philosopher Judith Butler — sex is somehow a cultural production, the result of labeling babies male or female. “Sex assigned at birth” should therefore be preferred over “sex,” not because it is more polite, but because it is more accurate.

This position tacitly assumes that humans are exempt from the natural order. If only! Alas, we are animals. Sexed organisms were present on Earth at least a billion years ago, and males and females would have been around even if humans had never evolved. Sex is not in any sense the result of linguistic ceremonies in the delivery room or other cultural practices. Lonesome George, the long-lived Galápagos giant tortoise , was male. He was not assigned male at birth — or rather, in George’s case, at hatching. A baby abandoned at birth may not have been assigned male or female by anyone, yet the baby still has a sex. Despite the confusion sown by some scholars, we can be confident that the sex binary is not a human invention.

Another downside of “assigned sex” is that it biases the conversation away from established biological facts and infuses it with a sociopolitical agenda, which only serves to intensify social and political divisions. We need shared language that can help us clearly state opinions and develop the best policies on medical, social and legal issues. That shared language is the starting point for mutual understanding and democratic deliberation, even if strong disagreement remains.

What can be done? The ascendance of “sex assigned at birth” is not an example of unhurried and organic linguistic change. As recently as 2012 The New York Times reported on the new fashion for gender-reveal parties, “during which expectant parents share the moment they discover their baby’s sex.” In the intervening decade, sex has gone from being “discovered” to “assigned” because so many authorities insisted on the new usage. In the face of organic change, resistance is usually futile. Fortunately, a trend that is imposed top-down is often easier to reverse.

Admittedly, no one individual, or even a small group, can turn the lumbering ship of English around. But if professional organizations change their style guides and glossaries, we can expect that their members will largely follow suit. And organizations in turn respond to lobbying from their members. Journalists, medical professionals, academics and others have the collective power to restore language that more faithfully reflects reality. We will have to wait for them to do that.

Meanwhile, we can each apply Strunk and White’s famous advice in “The Elements of Style” to “sex assigned at birth”: omit needless words.

Alex Byrne is a professor of philosophy at M.I.T. and the author of “Trouble With Gender: Sex Facts, Gender Fictions.” Carole K. Hooven is an evolutionary biologist, a nonresident senior fellow at the American Enterprise Institute, an associate in the Harvard psychology department, and the author of “T: The Story of Testosterone, the Hormone That Dominates and Divides Us.”
