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.

How Long Does It Last? Different materials decompose at different rates. How long does it take for these common types of trash to break down?

• Paper: 2-4 weeks
• Orange peel: 6 months
• Milk carton: 5 years
• Plastic bag: 15 years
• Tin can: 100 years
• Plastic bottle: 450 years
• Glass bottle: 500 years
• Styrofoam: Never

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.

Environmental Pollution: Causes and Consequences Essay

Environmental pollution is the unwarranted discharge of mass or energy into the planet’s natural resource pools, such as land, air, or water, which detriments the environment’s ecological stability and the health of the living things that inhabit it. There is an intensified health risk and pollution in middle and low-income countries due to the increased use of pesticides, industrialization, the introduction of nitrogen-based fertilizers, forest fires, urbanization, and inadequate waste management (Appannagari, 2017). Air pollution, lead and chemicals exposure, hazardous waste exposure, and inappropriate e-waste disposal all result in unfavorable living conditions, fatal illnesses, and ecosystem destruction. The essay will provide an overview of pollution and proffer solutions to combating pollution for a sustainable environment and health.

In addition to hindering economic development and considerably accelerating climate change, pollution exacerbates poverty and inequality in urban and rural areas. The most pain is always experienced by the poor, who cannot afford to protect themselves against pollution’s harmful effects. The main environmental factor contributing to sickness and early mortality is pollution due to premature deaths resulting from pollution (Appannagari, 2017). Due to the unacceptably high cost to human capital and health, as well as the resulting GDP losses, pollution must be addressed. Through initiatives like reducing black carbon and methane emissions, which are responsible for air pollution and climate change, pollution management can also significantly contribute to climate change mitigation (Appannagari, 2017). Additionally, pollution control can promote competitiveness through, for instance, job growth, increased energy efficiency, better transportation, and sustainable urban and rural development. Below are the various approaches for solutions to health and pollution problems.

First, governments should evaluate pollution as a national and international priority and integrate it into the city and country planning process. Pollution affects the health and well-being of societies and, as such, cannot be solely viewed as an environmental issue (The Lancet Commission on Pollution and Health, 2017). All levels of government should give pollution prevention a high priority, incorporate it into development planning, and tie it to commitments regarding climate change, SDGs, and the prevention of non-communicable diseases. Some options are both affordable and offer good returns on investment.

Secondly, governments should increase funding for pollution control and prioritize it by health impacts. There should be a significant increase in the financing for pollution management in low- and middle-income nations, both from national budgets and international development organizations (The Lancet Commission on Pollution and Health, 2017). The most effective international support for pollution reduction is when it mobilizes additional actions and funding from others. Examples include helping towns and nations that are quickly industrializing concerning technical capacity building, regulatory and enforcement support, and support for direct actions to save lives. Monitoring financing initiatives are necessary to determine their cost-effectiveness and to raise accountability.

Thirdly, organizations should work to build multicultural partnerships for pollution control. Public-private partnerships and interagency cooperation can be powerful tools in creating clean technology and energy sources that will ultimately prevent pollution at its source (The Lancet Commission on Pollution and Health, 2017). Collaborations between ministries that include the ministries of finance, energy, development, agriculture, and transport, as well as the ministries of health and the environment, are crucial in pollution control. Governments should promote monitoring systems that could identify and apportion pollution sources, measure pollution levels, guide enforcement, and assess progress toward goals. The use of new technology in pollution monitoring, such as data mining and satellite images, can boost effectiveness, broaden the monitoring area, and cut costs.

One of the main issues facing the world in the current period is pollution. Natural resources are depleting daily due to car emissions, new technologies, factories, and chemicals added to food. All of these factors seriously harm the world. However, the problems caused by pollution can be prevented by building multicultural partnerships, increasing funding for pollution control, integrating it into the country’s planning process, and adopting new technology for monitoring pollution. Preventing pollution lowers the cost to the environment and the economy.

Long Essay On Environmental Pollution

Environmental pollution is one of the biggest threats to our planet today. It affects both the environment and human health, and it’s becoming more and more pervasive in our daily lives. In this essay, we’ll explore what environmental pollution is, how it affects us, and what the most effective solutions are to reduce its impact on people and the planet.

Introduction

There are many different types of environmental pollution. Some of the most common include air pollution, water pollution, and soil contamination. Each type of pollution has different causes and effects. Air pollution is typically caused by emissions from factories and automobiles. These emissions can contain harmful chemicals that can cause respiratory problems, heart disease, and cancer. Water pollution is often caused by sewage or agricultural runoff. This pollution can contaminate drinking water supplies and make people sick. Soil contamination can be caused by hazardous waste disposal or mining operations. This contamination can make crops unsafe to eat and cause health problems in people who come into contact with it.

Causes of Environmental Pollution

There are many causes of environmental pollution. The most common cause is the release of harmful chemicals into the environment. These chemicals can come from factories, power plants, cars, and other sources. They can pollute the air, water, and soil. They can also cause health problems for people and animals.

Other causes of environmental pollution include sewage, agricultural runoff, and mining. Sewage can contain harmful bacteria and viruses that can pollute water supplies. Agricultural runoff can contain pesticides and fertilizers that can pollute rivers and lakes. Mining can release harmful metals and minerals into the environment.

Types of Pollutants and Their Impact on the Environment

There are many different types of pollutants that can have an adverse impact on the environment. Some of the most common pollutants include:

• Air pollution – This is one of the most visible forms of pollution and can cause a range of health problems, including respiratory illnesses.

• Water pollution – This can lead to contamination of drinking water supplies and also harm marine life.

• Soil pollution – This can contaminate crops and lead to soil erosion.

• Light pollution – This can disrupt the natural circadian rhythms of animals and cause light-sensitive species to suffer.

All of these pollutants can have a serious impact on the environment, both in terms of the immediate damage they cause and also the long-term effects. It is therefore important to be aware of the different types of pollutants and their potential impacts.

Effects Of Environmental Pollution

There are many effects of environmental pollution. Some of the most common include air pollution, water pollution, and soil contamination.

Air pollution is one of the most harmful forms of environmental pollution. It is a major contributor to respiratory problems, heart disease, and cancer. Air pollution is also a leading cause of climate change.

Water pollution is another major problem caused by environmental pollution. It can contaminate drinking water supplies, damage aquatic ecosystems, and make recreation in waterways unsafe.

Soil contamination can occur when pollutants such as chemicals or oil spills enter the ground. This can make crops difficult to grow and can contaminate food supplies. Soil contamination can also cause health problems if people come into contact with contaminated soil or eat contaminated food.

Prevention and Control Measures

There are a number of things that individuals can do to help prevent and reduce environmental pollution. One of the most important things is to educate yourself and others about the issue and its causes. This can help raise awareness and create a demand for change. Another key prevention measure is to support businesses and industries that are working to reduce their pollution output. This includes voting with your wallet by patronizing companies that have green policies in place, and investing in cleaner energy sources. Finally, you can take action in your own life to reduce your impact on the environment. This includes conserving energy, recycling, driving less, and composting.

In conclusion, environmental pollution has become a major global concern and it is important for us to take proactive steps to reduce the amount of pollutants that are entering our environment. We can start by reducing our consumption of single-use products, switching to renewable energy sources such as solar or wind power, and engaging in conscientious recycling habits. By taking these actions we can help protect our planet from further harm caused by environmental pollution.

Essay on Pollution

An essay on pollution is an essential concept for students as it reveals the consequences of human activities on the environment. Read on to explore how to write an intriguing and engaging essay on pollution.

Essay on Pollution – Important Guidelines

Please consider adopting the following suggestions when writing an essay on pollution. Moreover, these suggestions will be helpful for most other essays as well.

• Begin with an introductory paragraph, preferably highlighting the history or insight of the topic.
• Try to avoid jargon unless the topic demands so.
• Use bulleted points to present content wherever possible
• Incorporate factual data, such as dates, names and places wherever possible.
• Avoid writing a large monotonous block of text. Always break up the content into easily digestible chunks
• Try to conclude the essay with a closing paragraph.

Essay on Pollution – Sample 1

Pollution had existed long before humans evolved. For instance, volcanic eruptions commonly pumped massive amounts of sulphur dioxide into the atmosphere, causing acid rain. The greenhouse gas, ozone, forms from natural, photochemical reactions in the atmosphere. 

However, significant levels of pollution occurred only after the Industrial Revolution, when untreated exhausts and toxic waste products were released into the environment. Air pollution was rampant, with thick, toxic smog covering most towns and cities. Water pollution affected many water bodies. Toxic substances leached into the soil, hampering the soil quality.

Today, there have been many measures to curb the effects of pollution, but its repercussions can still be observed. For instance, the land and sea ice near the poles have been decreasing at an alarming rate. This has led to the debate regarding climatic factors and their impact on our environment. There was a time when lead used to be added to motor fuel. This substance, combined with the world’s increasing demand for motor vehicles, caused a spike in air pollution. What made this air pollution more dangerous is the fact that the air had high levels of lead.

Lead is toxic and can cause a vast array of health problems. The most common illnesses are neurological in nature. Lead can also travel through the placenta, between a mother and her unborn child. Moreover, young children and infants are even more sensitive to lead. They can develop learning deficits, behavioural problems and also a low IQ.

Furthermore, some studies have arrived at a “lead-crime postulate”, where children who were exposed to high levels of lead were more likely to indulge in criminal activities. This correlation was made as to the crime rates during the 1980s, and early 1990s were rather high. Lead can also cause neurological effects on vertebrates and impair the reproductive capabilities of plants. More ominously, lead can be absorbed into the tissues of such organisms, and they can pass it on to us when we consume them.

Technological progress also brings newer forms of pollution. Radioactive pollution is one of the rarer types of pollution. This type of pollution occurs naturally as well – elements such as uranium and thorium are present in rocks and soil. Carbon-14 is a radioactive isotope of carbon naturally present in all living organisms. It is created by cosmic rays. However, these natural sources of radiation are of little concern. Only anthropogenic sources of radioactivity are considered lethal sources of pollution. For instance, the Chernobyl nuclear disaster is the most publicised nuclear disaster ever to occur. The total death count was documented to be at 16,000. However, unofficial reports indicated that the death toll was much higher. Most deaths occurred due to acute radiation poisoning and many other deaths were caused due to radioactivity-induced cancer. Though it has been more than a few decades, radioactivity still persists around the site of the nuclear reactor. Efforts to contain the radioactivity included building the Shelter Structure, more popularly known as the “sarcophagus”. It was built in December 1986 and enclosed the reactor, preventing radiation from leaking through the building. 

Though the levels of pollution have dropped down since the industrial revolution, we still see many repercussions to this day. Following are some extreme cases of pollution caused by anthropological activities.

The Great Smog of London was a severe case of air pollution that occurred in 1952. The event caused massive disruption by severely affecting visibility. It also caused a variety of respiratory illnesses in 1,00,000 individuals and the death of over 4,000 as a direct result of the smog. 

In India, pollution is even more rampant. Delhi has recorded one of the worst cases of air pollution, with the air rated as “hazardous” in November 2017.

Environmental Pollution Essay

Pollution is the presence and inclusion of unwanted items in the environment. The state of the environment is altered when it has become contaminated with potentially dangerous compounds as a result of human activity. Water, air, and land are dangerously affected by the pollution. Here are a few sample essays on environmental pollution:

100 Words Essay on Environmental Pollution

200 words essay on environmental pollution, 500 words essay on environmental pollution.

When it comes to protecting the environment, awareness is the key. As more and more people become aware of the causes, types, and impacts of environmental pollution, they are more likely to take steps to prevent it. Air pollution is created as a result of burning fossil fuels, such as coal, oil, and natural gas. Water pollution results from industrial activities, such as the dumping of chemicals into rivers and lakes, as well as from agricultural runoff. Land pollution is caused by the misuse of land and improper disposal of waste. The causes of environmental pollution are numerous and varied. Some of the main culprits are industrial activities, burning of fossil fuels, use of pesticides, and deforestation.

Awareness and taking necessary resolving steps is essential when it comes to protecting the environment from the impacts of environmental pollution. By teaching people the importance of taking steps to prevent environmental pollution, we can ensure a brighter future for our planet. We must understand the causes of environmental pollution, the types of pollution, the impact it has on the environment, and how we can prevent it.

Causes | Environmental pollution is the contamination of the environment through the emissions of pollutants including harmful gases, chemicals, and particulate matter. It is caused by human activities such as burning of fossil fuels, deforestation, and industrial pollution. These activities have caused global warming, acid rain, and water and air pollution, leading to global environmental degradation.

Types | There are different types of environmental pollution. The most common type is air pollution, which is caused by burning of fuels and other industrial activities. Water pollution is another common type of pollution which is caused by sewage and industrial waste. Soil pollution is caused by overuse of pesticides and other chemicals. Noise pollution is caused by traffic, construction activities, and industrial noise. Light pollution is caused by the emission of artificial light.

Impact | The impact of environmental pollution is far-reaching and devastating. Air pollution can lead to respiratory diseases, while water pollution can contaminate drinking water and cause health issues. Land pollution causes reduction in soil fertility and even destruction of natural habitats for animals. In addition, it can lead to the destruction of ecosystems, which in turn leads to a decrease in biodiversity.

Environmental pollution has serious impacts on both humans and the environment. It affects air quality, water quality, soil fertility, and public health. Poor air quality affects the respiratory system, leading to respiratory illnesses like asthma and bronchitis. Water pollution can lead to the spread of diseases like cholera, typhoid, and dysentery. Soil pollution can reduce crop yields, leading to food insecurity.

Types of Environmental Pollution

Air | Air pollution is the introduction of dangerous compounds into the atmosphere, which has a negative influence on the environment and humanity. Air pollution simply makes the air impure or contaminated. It happens when noxious gases, scents, dust, or fumes are discharged into the air in concentrations that endanger human and animal comfort or health or even kill plant life.

Water | The act of contaminating water bodies, such as rivers, oceans, lakes, streams, aquifers, and groundwater, is known as water pollution. It happens when foreign, dangerous substances—such as chemicals, garbage, or polluted materials are released into bodies of water, either directly or indirectly.

Land | When the quality of the earth's land surfaces in terms of use, landscape, and capacity to support life forms is compromised or destroyed, this is referred to as land pollution. It is frequently brought on by human activity and the misuse of land resources, both directly and indirectly.

Soil | Chemical pollutants can pollute soil or cause it to degrade through activities like mining, clearing vegetation, or topsoil erosion. Typically, it occurs when human activities bring harmful chemicals, substances, or items into the soil.

Noise | Noise pollution is an unpleasant sound or a sound that causes excruciating ear pain. Noise pollution is described as unpleasant and unwanted sound levels that cause significant distress to all living beings. It is measured in decibels (dB).

Factors Responsible For Environmental Pollution

Environmental pollution has a variety of causes. One of the most prominent is the burning of fossil fuels, such as coal, oil and gas by power plants, factories and automobiles. This produces large amounts of carbon dioxide, which is a major contributor to global climate change. Other sources of environmental pollution include agricultural practices, such as over-fertilization and the use of pesticides, and industrial processes, such as mining, manufacturing and waste disposal.

What Can We Do

To prevent environmental pollution, we must reduce the emissions of various pollutants. We can do this by switching to renewable sources of energy like solar, wind, and hydroelectric power. We should reduce our reliance on fossil fuels and use more efficient transportation methods. We should also reduce the emissions of harmful industrial chemicals and practise sustainable agriculture. Additionally, we should increase public awareness of environmental pollution and its impacts, and promote eco-friendly lifestyles.

By understanding the causes and effects of environmental pollution, we can work towards preventing it and ensuring a cleaner, healthier environment for all. Awarness and knowledge is essential in this regard, as it helps us to become more conscious and informed citizens. It helps us understand the importance of protecting and preserving the environment and make us more responsible citizens.

The world is facing an ever-growing threat from pollution, which if left unchecked will have catastrophic consequences. Education and taking conscious action plan can play a key role in helping to reduce environmental pollution.

• Air Pollution Essay

Essay on Air Pollution

Environmental changes are caused by the natural or artificial content of harmful pollutants and can cause instability, disturbance, or adverse effects on the ecosystem. Earth and its environment pose a more serious threat due to the increasing pollution of air, water, and soil. Environmental damage is caused by improper resource management or careless human activities. Therefore, any activity that violates the original nature of the environment and leads to degradation is called pollution. We need to understand the origin of these pollutants and find ways to control pollution. This can also be done by raising awareness of the effects of pollutants.

Air pollution is any physical, chemical, or biological change in the air. A certain percentage of the gas is present in the atmosphere. Increasing or decreasing the composition of these gasses is detrimental to survival. This imbalance in gas composition causes an increase in global temperature which is called global warming.

Introduction to air pollution 

The Earth and its environment are facing a serious threat by the increasing pollution of the air, water, and soil—the vital life support systems of the Earth. The damage to the environment is caused by improper management of resources or by careless human activity. Hence any activity that violates the original character of nature and leads to its degradation is called pollution. We need to understand the sources of these pollutants and find ways to control pollution. This can be also done by making people aware of the effects of pollutants. 

Air with 78% Nitrogen, 21% Oxygen, and 1% of all other gasses support life on Earth. Various processes take place to sustain the regular percentage of gasses and their composition in general. 

Atmospheric pollution can have natural sources, for example, volcanic eruptions. The gaseous by-products of man-made processes such as energy production, waste incineration, transport, deforestation and agriculture, are the major air pollutants.

Although air is made up of mostly Oxygen and Nitrogen, mankind, through pollution, has increased the levels of many trace gasses, and in some cases, released completely new gasses to the atmosphere. 

Air pollution can result in poor air quality, both in cities and in the countryside. Some air pollutants make people sick, causing breathing problems and increasing the likelihood of cancer. 

Some air pollutants are harmful to plants, animals, and the ecosystems in which they live. Statues, monuments, and buildings are being corroded by the air pollutants in the form of acid rain. It also damages crops and forests, and makes lakes and streams unsuitable for fish and other plant and animal life. 

Air pollution created by man-made resources is also changing the Earth’s atmosphere. It is causing the depletion of the ozone layer and letting in more harmful radiation from the Sun. The greenhouse gasses released into the atmosphere prevents heat from escaping back into space and leads to a rise in global average temperatures. Global warming affects the average sea-level and increases the spread of tropical diseases.

Air pollution occurs when large amounts of gas and tiny particles are released into the air and the ecological balance is disturbed. Each year millions of tons of gasses and particulate matter are emitted into the air. 

Primary air pollutants are pollutants, which are directly released into the air. They are called SPM, i.e., Suspended Particulate Matter. For example, smoke, dust, ash, sulfur oxide, nitrogen oxide, and radioactive compounds, etc.

Secondary Pollutants are pollutants, which are formed due to chemical interactions between the atmospheric components and primary pollutants. For example, Smog (i.e. Smoke and fog), ozone, etc.

Major gaseous air pollutants include Carbon Dioxide, Hydrogen Sulfide, Sulfur Dioxide and Nitrogen Oxide, etc.

Natural sources are volcanic eruptions, forest fires, dust storms, etc. 

Man-made sources include gasses released from the automobiles, industries, burning of garbage and bricks kilns, etc.

Effects of Air Pollution on Human Health

Air pollution has adverse effects on human health. 

Breathing polluted air puts you at higher risk of asthma.

When exposed to ground ozone for 6 to 7 hours, people suffer from respiratory inflammation.

Damages the immune system, endocrine, and reproductive systems.

A high level of air pollution has been associated with higher incidents of heart problems.

The toxic chemicals released into the air are affecting the flora and fauna immensely.

Preventive Measures to Reduce Air Pollution

We can prevent pollution by utilizing raw materials, water energy, and other resources more efficiently. When less harmful substances are substituted for hazardous ones, and when toxic substances are eliminated from the production process, human health can be protected and economic wellbeing can be strengthened. 

There are several measures that can be adopted by people to reduce pollution and to save the environment.

Carpooling.

Promotion of public transport.

No smoking zone.

Restricted use of fossil fuels.

Saving energy.

Encouraging organic farming.

The government has put restrictions on the amount of fossil fuels that can be used as well as restrictions on how much carbon dioxide and other pollutants can be emitted. Although the government is attempting to save our environment from these harmful gasses, it is not sufficient. We as a society need to keep the environment clean by controlling the pollution of air.

FAQs on Air Pollution Essay

1. State the Causes of Air Pollution ?

The following are the causes of air pollution.

Vehicular pollution consisting of Carbon Monoxide causes pollution.

Emission of Nitrogen oxide by a large number of supersonic transport airplanes causes deterioration of the Ozone layer and also causes serious damage to the flora and fauna.

The release of Chlorofluorocarbons into the Stratosphere causes depletion of Ozone, which is a serious concern to animals, microscopic, and aquatic organisms.

Burning garbage causes smoke, which pollutes the atmosphere. This smoke contains harmful gases such as Carbon dioxide and Nitrogen oxides.

In India, brick kilns are used for many purposes and coal is used to burn the bricks. They give out huge quantities of Carbon dioxide and particulate matter such as smoke, dust that are very harmful to people working there and the areas surrounding it. 

Many cleansing agents release poisonous gases such as Ammonia and Chlorine into the atmosphere. 

Radioactive elements emit harmful rays into the air.

Decomposed animals and plants emit Methane and Ammonia gas into the air.

2. What Does Global Warming Mean?

Global warming is the gradual rising average temperature of the Earth's atmosphere due to the concentration of methane in certain toxic gasses such as carbon dioxide. This has a major impact on the world climate. The world is warming. The land and the sea are now warmer than they were at the beginning and temperatures are still rising. This rise in temperature is, in short, global warming. This temperature rise is man-made. The burning of fossil fuels releases greenhouse gasses into the atmosphere which capture solar heat and raise surface and air temperatures.

3. Name the Alternative Modes of Transport. In What Way Does it Help to Reduce Air Pollution?

Public transport could be an alternative mode of transport. Public transport like trains, buses and trams, can relieve traffic congestion and reduce air pollution from road transport. The use of public transport must be encouraged in order to develop a sustainable transport policy.

4. Mention other means of transportation! How can I help reduce air pollution?

Public transportation can be another mode of transportation. Public transport such as trains, buses and trams can reduce traffic congestion and reduce air pollution from road transport. The use of public transport and to develop sustainable transport policies should be encouraged. While one passenger vehicle has the convenience factor, other modes of transportation reduce travel costs, spend less time, reduce stress, improve health, and reduce energy consumption and parking. Other trips for work include walking/cycling, public transport, hybrid travel and transport.

5. What are the effects of pollution?

Excessive air pollution can increase the risk of heart attack, wheezing, coughing and difficulty breathing, as well as irritation of the eyes, nose and throat. Air pollution can also cause heart problems, asthma, and other lung problems. Due to the emission of greenhouse gases, the composition of the air in the air is disturbed. This causes an increase in global temperature. The damaging ozone layer due to air pollution does not prevent harmful ultraviolet rays from the sun, which cause skin and eye problems in individuals. Air pollution has caused a number of respiratory and heart diseases among people. The incidence of lung cancer has increased in recent decades. Children living in contaminated areas are more likely to develop pneumonia and asthma. Many people die every year due to the direct or indirect effects of air pollution. When burning fossil fuels, harmful gases such as nitrogen oxides and sulfur oxides are released into the air. Water droplets combine with these pollutants and become acidic and fall as acid rain, which harms human, animal and plant life.

6. What is the solution to air pollution?

Production of renewable fuels and clean energy. The basic solution to air pollution is to get away from fossil fuels and replace them with other energies such as solar, wind and geothermal. The government limits the amount of fossil fuel that can be used and how much carbon dioxide and other pollutants it can emit. While the government is trying to save our environment from this harmful gas, it is not enough. We as a society need to keep the environment clean by controlling air pollution.

Introduction

Pollution has significant impacts on human health , the environment, and even on how some of the Earth’s systems, such as the climate, are functioning. Pollution touches all parts of the planet. It is affecting our health through the food we eat, the water we drink and the air we breathe. Approximately 19 million premature deaths are estimated to occur annually as a result of the way we use natural resources to support global production and consumption and which impact the environment.

Pollution touches all parts of the planet. It is affecting our health through the food we eat, the water we drink and the air we breathe. Approximately 19 million premature deaths are estimated to occur annually as a result of the way we use natural resources and impact the environment to support global production and consumption.

The 2030 Agenda for Sustainable Development adopted by the United Nations in 2015 commits to “ensure that all human beings can enjoy prosperous and fulfilling lives and that economic, social and technological progress occurs in harmony with nature”. How does pollution fit in that picture?

What are the sources of pollution?

Pollution can take many forms, ranging from organic compounds and other chemical substances to different types of energy. Some types of pollution are easily noticed, such as certain forms of contaminated water, poor air quality, industrial waste, litter , light, heat and noise. Others are less visible, for example pesticides in food, mercury in fish, excess nutrients in the sea and lakes, endocrine-disrupting chemicals in drinking water, and other micro- pollutants in fresh and marine water. Some, such as those coming from abandoned industrial sites, armed conflict zones, nuclear power stations, pesticide stockpiles and waste landfills , form part of a longer-term legacy.

The sources and types of pollution are highly diverse, as are the solutions to deal with them. For example, hazardous chemicals in paints, cleaning compounds, dyes, electronic products, and many other household substances can become pollutants if not managed correctly. Ecosystem functions are put at risk as well. There are also many emerging and novel products, such as some therapeutic drugs and nanomaterials , for which data on potential pollution effects are sparse.

On the other hand, food waste globally has been estimated to be as high as one third of all food produced for human consumption – nearly 1.3 billion tons.

Figure 3: Major sources of today's pollution

Market demand on one side of the planet is often satisfied by labour, production and natural resources originating from halfway across the globe. Fossil fuels now account for 50 per cent of the global trade volume. Research finds that trade leads to a redistribution of environmental burden towards countries that extract and produce resources. As such, the environmental impacts and pollution generated by global consumption habits are disassociated from those most impacted locally. Trade patterns, policies and agreements can play a crucial role in internalizing some of the environmental and social costs of production in order to minimize pollution at a global scale .

Air pollution

One important source of air pollution is indoor air pollution produced by the use of solid fuels for cooking in the house. The other major source of air pollution is outdoor pollution resulting from the burning of fossil fuels . Wildfires, the burning of waste, and tobacco smoke, all also contribute to air pollution. It is estimated that nine out of ten people in the world are breathing air that is polluted beyond the World Health Organisation (WHO) acceptable standards.

Land and soil pollution

Land and soil pollution is largely due to agricultural practices, to improper irrigation, to solid waste management problems such as landfills , and to a range of industrial, military and extractive activities. Globally, estimates indicate that at least 1 million people are unintentionally poisoned every year by excessive exposure and inappropriate use of pesticides , with health effects on all.

The waste products of industrial processes or mining activities are another source of pollution as they may contain heavy metals , pharmaceuticals and microorganisms , which can be difficult to remove once they find their way into the environment. Former industrial or military sites that are no longer in use can also be the sources of pollutants if they are not decontaminated properly. While some high-income countries have programs and regulations to deal with soil pollution, many poorer nations lack such programs, and are at risk to form ‘pollution hotspots’.

Freshwater pollution

Rivers and lakes are heavily affected by pollution, especially by the excess nutrients that come from the use of fertilisers in agriculture, one of the most pervasive water quality issues on a global scale , interfering with many human water uses and causing major shifts of species in ecosystems and loss of biodiversity .

Over 80 per cent of the world's wastewater is released to the environment without treatment creating a pollution from pathogens as well as from chemicals such as heavy metals from mining and industrial waste. These lead to a loss of biodiversity and to water that is improper for human consumption.

Marine and coastal pollution

Oceans receive most of their pollutants from land through rivers in the form of nutrients , waste, heavy metals and plastic debris which fragment into pieces of less than 5 mm but do not biodegrade in the marine environment. The rest comes from the fishing, shipping, and energy industries. The impacts of ocean acidification, which are for a large part associated with the dissolution of carbon dioxide emissions, are most visible on marine species with calcareous skeletons, such as corals and plankton which form the base of many marine food webs.

What are the impacts of pollution?

The severity of a pollutant for human health and ecosystems is dependent on its chemical nature and intrinsic toxicity, quantities emitted, exposure concentrations and persistence. Highly hazardous chemicals, such as mercury , ammonium, ozone, and some organic compounds used in a range of industries have the potential to cause cancer , birth defects , induce genetic damage, cause miscarriage, injury or death from relatively small exposures , if released into the environment. The specific harm caused by different pollutants depends not only on the environment where it is emitted (air, water or soil) but also possibly on the mix of pollutants that are present and the actual level of exposure. For example, about 125 million people in the world are exposed to asbestos at the workplace with over 100,000 still dying annually from such exposure.

Pollution poses a direct threat to respecting, protecting and promoting human rights and gender equality, international human rights obligations related to health, life, food and water. Due to their general health status, potential higher exposures and reduced resilience to social, environmental and economic risks, pollution can have a particularly disproportionate and negative effect on the poor, the disadvantaged, the marginalized, indigenous peoples, the disabled and the vulnerable . For instance, children poisoned by mercury and lead develop problems
in their nervous and digestive systems and kidney damage. In addition, many toxic dumpsites are located in poor areas, leading to environmental injustice.

Pollution has also significant economic costs from the point of view of health, productivity losses, health-care costs and ecosystem damages. If consumption and production patterns continue as they are, the linear economic model of “take-make-dispose” will seriously burden an already polluted planet, affecting current and future generations.

For instance, in 2013 it was estimated that the cost of air pollution was more than 5 000 billion USD, which is more than the annual budget of the United States. These substantial costs, are expected to rise over time, not only because of the direct effect of pollution on health, but also because of the impact of weakened livelihoods, as well as the longer-term impact on ecosystem services , that in turn affect local communities , societies and economies. With a better understanding of the economic costs of pollution, the human costs of pollution are critical information for decision-making and to support more effective policies.

If consumption and production patterns continue as they are, the linear economic model of “take-make-dispose” will seriously burden an already- polluted planet, affecting current and future generations.

What is currently being done to address pollution?

Pollution is not a new phenomenon; it is largely controllable and often avoidable, but still considerably neglected. Thanks to better knowledge, alternative consumption and production models, as well as innovative technological solutions, many countries, cities, and businesses can now successfully tackling serious pollution issues.

Today, a majority of UN Member States recognize environmental rights. The first Principles of both the 1972 Stockholm and 1992 Rio Declarations focused on the human right to a safe and clean environment. The Stockholm Declaration describes “the fundamental right to freedom, equality and adequate conditions of life, in an environment of a quality that permits a life of dignity and well-being...”, while the Rio Declaration states that humans “are entitled to a healthy and productive life in harmony with nature”. These declarations have, together with other principles, informed many national constitutions over the past three decades.

At the same time, voluntary environmental initiatives have supported more formal environmental agreements, resulting in progress in some areas. But even more robust governance frameworks are required to bring us closer to a pollution-free planet. In particular, the 17 Sustainable Development Goals of the United Nations 1 provide an opportunity to accelerate the implementation of targeted and time-bound actions on pollution, which have been hitherto limited and inadequate.

With regards to chemicals and waste, legally binding approaches at the global level are essential to addressing the most critical and complex pollution challenges.

Existing multilateral environmental agreements already enable actions. This was notably in relation to the ban and substitution of ozone-depleting substances achieved in 2015, to the elimination of persistent organic pollutants and of most hazardous industrial chemicals and pesticides in international trade, as well as to hazardous and household waste and in particular to mercury with the entry into force of the Minamata Convention in 2017. Several of the multilateral environmental agreements were ratified worldwide or nearly worldwide.

The Convention on Biological Diversity’s Aichi Biodiversity Targets 2 also calls for a decrease in pollution and demands specific actions on excess nutrients . Today, a majority of UN Member States recognizes environmental rights. As of 2015, over 100 countries guaranteed their citizens a right to a healthy environment, with the majority of countries building this into their national constitutions. Although no international agreement explicitly recognizes the right to a healthy environment, national constitutions have played a vital role at the forefront of human rights and environmental protection . The majority of constitutional environmental rights include substantive, procedural, and emerging rights, such as the right to health and food, while others refer to policy-based, reciprocal-duty, and miscellaneous provisions.

Encouragingly, more governments, industries and citizens are moving towards sustainable materials management, greater resource efficiency, less environmentally damaging chemistry, clean technologies, and circular economies, as part of a more comprehensive transformation towards a sustainable economy. Trade can lead to greater environmental burdens in countries that extract and produce resources, as such activities generate waste and emissions. But trade can also provide solutions in terms of improved environmental goods and services . However, the capacity to adequately tackle pollution varies hugely across regions, social groups and genders.

At the same time, responses by governments, business and citizens to pollution remain sometimes limited in scope and scale and to date, there are no legally binding agreements that systematically address pollution in all its forms. If global and regional environmental agreements provide a partial framework, there are many gaps. For example, some agreements are only target-based, some are time-bound, while others cover also compliance-related actions, monitoring and reporting. For example, voluntary initiatives and global alliances – on topics such as fuel efficiency improvements, cleaner air and lead in paint – have addressed some of the more urgent issues, yet much more remains to be done to control and prevent pollution.

What are the benefits of addressing pollution?

It is obvious from many case studies that tackling pollution has already brought multiple benefits even if current responses may still be limited and inadequate. Projections indicate that further actions have the potential to enhance both health, well-being, and the economy. Two success stories show what can be achieved: the healing of the ozone layer and the phasing out of lead in fuel.

• The Montreal Protocol ensured that to date more than 99 per cent of the historic baseline levels of consumption and production of harmful ozone-depleting substances have been phased out and its Multilateral Fund provided roughly $3.7 billion to more than 140 countries to phase out ozone-depleting substances, with lasting influence on innovation, technology transfer, strengthening of environmental governance , and training of customs officers and technicians. As a result, the ozone layer is healing and is expected to be restored by the middle of the century. Consequently, up to two million cases of skin cancer may be prevented each year by 2030, decreases in agricultural and fisheries yields will be avoided and up to 0.5°C of global warming will be avoided by the end of the century as ozone-depleting susbstances were also responsible of about 20% of the greenhouse gas emissions.
• For lead additives in fuels the phase out is now almost complete, with only three countries still using some lead in fuel, all of which are set to stop by the end of 2017. Governments, the oil and auto industries, and civil society have worked together to support a global shift to unleaded fuels. This massive shift prevents an estimated 1.2 million premature deaths every year, and it also has a positive impact on children’s intellectual ability as lead is known to affect children’s IQ (United Nations Environment Programme 2016a).

Traditional pollution control that relies on “end-of-pipe” technologies has been shown to reduce polluting substances, such as in the case of sulphur dioxide (SO 2 ) and nitrogen oxides (NO x ) emissions from heating and energy production units. However, these technologies also require materials and energy upfront to produce the equipment, and as a consequence, may increase environmental impacts.

What actions can be taken to make the world truly pollution-free?

Solutions to help remove pollutants and detoxify our environment exist around the world. These need to be expanded, shared, and scaled up in order to avoid risking further exposure of humans and ecosystems to current and future pollution as well as increasing the costs of clean up. Improved risk assessment of new pollution sources is also urgently needed. Transitioning to a pollution-free world can drive innovation and social equity throughout the economy, by seeing pollution prevention and regulation compliance as an opportunity to clean up everyone’s environment, create new jobs, improve economic productivity and protect the rights of this and future generations.

Resource efficiency over the whole production -consumption system in particular can generate products which are identical or have the same functionality as when using traditional technologies and processes, while also reducing critical emissions and mitigating resource requirements and environmental impacts in the upstream processes.

Moving to less-polluting and nature-based technologies also offers economic and employment opportunities. Renewable energy provided jobs for 9.8 million people worldwide in 2016, compared to 5.7 million in 2012. Waste recycling and reuse also offers the chance to convert waste into economic opportunities, including jobs. As secondary materials replace virgin materials (for example phosphate from fertilizer nutrient recovery), they reduce the resource and environmental footprint of growth, but they can also have income and job impacts on primary exporting countries. Thus, careful and inclusive transition planning is required for those affected by these transformations. It is estimated that the global market for environmental goods and services reached $866 billion in 2011, and is expected to rise to $1.9 trillion by 2020.

However, challenges and gaps still limit the effectiveness of current actions. The key gaps are:

• implementation,
• infrastructure,
• limited financial and industry leadership,
• pricing and fiscal, and
• behavioural.

Implementation gaps are in particular due to a lack of resources; inadequate administrative, financial, institutional and technical capacity, and the absence of inter-ministerial coordination and political will. Absence of inter-ministerial coordination being a key reason why action does not happen.

There is also insufficient recognition by different actors that producer and consumer choices have pollution consequences. Such choices – even in the presence of pollution policies and regulations – can be made out of habit, a feeling that one person or firm cannot make a difference.

This report “Towards a pollution-free planet” is about encouraging a synergetic mix of actions and a whole-system, multi-beneficial policymaking approach that builds directly on existing internationally agreed environmental goals, including those relating to climate change , disaster and risk reduction and the 2030 Agenda for Sustainable Development , with its numerous pollution-reducing targets. As already underlined, existing international environmental agreements and the 2030 Agenda for Sustainable Development present significant opportunities to accelerate actions to tackle pollution and improve the well-being of humans and ecosystems . The international framework for the Sustainable Development Goals encourages synergies between the Goal 3 and its associated target to “substantially reduce the number of deaths and illnesses from hazardous chemicals and air, water and soil pollution and contamination”, and others such as the targets for climate change, air quality, nutrient pollution and marine debris. These links are detailed in the appendices of the report.

A pollution-free planet is by far and away the best insurance for the survival and well-being of current and future generations of humans and ecosystems . To advance this goal, this report has the following five overarching messages

• A global compact on pollution would make prevention a priority for all. It would also encourage policymakers to integrate prevention into national and local planning, development processes, poverty reduction strategies and national accounts;
• Environmental governance needs to be strengthened at all levels – with targeted action on “hard-hitting” pollutants through risk assessments and enhanced implementation of environmental legislation (including multilateral environmental agreements) and other measures;
• Sustainable consumption and production should be promoted through improved resource efficiency and lifestyle changes, waste reduction and management being prioritized;
• Investment in cleaner production and consumption will help to counter pollution , alongside increased funding for pollution monitoring , infrastructure, management and control;
• Multi- stakeholder partnerships and collaboration are vital for the innovation, knowledge-sharing and transdisciplinary research needed to develop technological and ecosystem -based solutions.

To reach these objectives, this report suggests a dual track of actions as framework for actions on pollution that UN Member States and other stakeholders may wish to consider to curb pollution around the world. This dual framework consists in the following combination:

• Targeted interventions , based on risk assessments and scientific evidence of impacts, to address “hard-hitting” pollutants as well as areas of pollution (air, water, marine and coastal, land/soil), including cross-cutting categories (chemicals, waste);
• System-wide transformations to shift the economy toward greater resource efficiency and equity , circularity and sustainable consumption and production , and improved ecosystem resilience to support cleaner and more sustainable development .

This dual track of actions is guided and underpinned by the two other elements of the framework:

• The five principles drawn from the Rio Declaration and the 2030 Agenda for Sustainable Development : universality, sustainability , integration, precaution and inclusiveness.
• Enablers, or broader supporting actions, to shift incentives, correct market and policy failures and address some of the gaps and issues that make pollution so pervasive and persistent .

The report then present in more details the actions that should be undertaken to tackle the challenges in the various areas and lead to a “pollution-free planet”.

250 Words Essay on Environmental Pollution

Environmental pollution, a global menace, has been escalating at an alarming rate, posing a significant threat to our planet’s biodiversity and human health. The reckless exploitation of natural resources and relentless industrialization have been the primary contributors to this predicament.

Types of Environmental Pollution

Environmental pollution is primarily classified into air, water, and soil pollution. Air pollution, caused by the release of harmful gases and particulates, leads to respiratory diseases and global warming. Water pollution, on the other hand, is the result of dumping untreated waste and chemicals into water bodies, causing harm to aquatic life and contaminating drinking water. Soil pollution, caused by the excessive use of fertilizers and pesticides, affects plant growth and can lead to food contamination.

Impacts of Environmental Pollution

The impacts of environmental pollution are far-reaching and devastating. It not only disrupts ecosystems but also contributes to biodiversity loss, climate change, and human health issues. The increase in the Earth’s average temperature, melting ice caps, and rising sea levels are all consequences of pollution-induced global warming.

In conclusion, environmental pollution is a pressing issue that requires immediate attention and action. It is crucial for us, as responsible inhabitants of this planet, to adopt sustainable practices and encourage others to do the same. The future of our planet rests in our hands, and every step taken towards its preservation counts.

500 Words Essay on Environmental Pollution

Introduction to environmental pollution.

Environmental pollution, a global concern, is the introduction of contaminants into the natural environment causing adverse changes. These pollutants, usually generated by human activities, upset the balance of ecosystems, affecting their inhabitants and the environment itself.

The Different Types of Environmental Pollution

Environmental pollution manifests in various forms. Air pollution, caused by industrial emissions and vehicle exhaust, leads to global warming and respiratory illnesses. Water pollution, resulting from industrial waste, oil spills, and plastic waste, has devastating effects on aquatic life and water quality. Soil pollution, due to agricultural chemicals and waste disposal, impairs plant growth and can contaminate food sources. Noise pollution, often overlooked, can cause stress and hearing loss in both humans and animals.

The Impact of Environmental Pollution on Biodiversity

Environmental pollution severely affects biodiversity. Pollutants can cause immediate harm to organisms or subtly alter habitats over time, leading to reduced species diversity. For instance, oil spills can kill marine life instantly, while acid rain, a byproduct of air pollution, slowly makes lakes uninhabitable for many species. Such changes can disrupt ecosystems, as species interdependencies are complex and often poorly understood until a key species is lost.

Human Health and Environmental Pollution

Environmental pollution also poses significant risks to human health. Air pollution can lead to respiratory diseases and cancer, while contaminated water can cause gastrointestinal illnesses and other diseases. Prolonged exposure to noise pollution can result in hearing impairment and stress-related conditions. Furthermore, pollution-induced changes in the environment can lead to resource scarcity, contributing to conflicts and migration.

The Role of Legislation and Public Awareness

Effective legislation and public awareness are crucial in combating environmental pollution. Strict laws can regulate pollutant emissions, waste disposal, and resource use. However, laws alone are not enough. Public awareness and education about the harmful effects of pollution are necessary to stimulate behavioral changes. When individuals understand the impact of their actions, they are more likely to adopt sustainable practices.

Conclusion: The Urgency of Addressing Environmental Pollution

Environmental pollution is a complex issue that requires immediate attention. Its impacts are far-reaching, affecting biodiversity, human health, and social stability. While legislation can provide a framework for action, public awareness and individual responsibility are key to achieving a sustainable future. By understanding and addressing environmental pollution, we can help ensure the health and longevity of our planet.

Essay on Air Pollution for Students and Children

500+ words essay on air pollution.

Essay on Air Pollution – Earlier the air we breathe in use to be pure and fresh. But, due to increasing industrialization and concentration of poisonous gases in the environment the air is getting more and more toxic day by day. Also, these gases are the cause of many respiratory and other diseases . Moreover, the rapidly increasing human activities like the burning of fossil fuels, deforestation is the major cause of air pollution.

How Air Gets Polluted?

The fossil fuel , firewood, and other things that we burn produce oxides of carbons which got released into the atmosphere. Earlier there happens to be a large number of trees which can easily filter the air we breathe in. But with the increase in demand for land, the people started cutting down of trees which caused deforestation. That ultimately reduced the filtering capacity of the tree.

Moreover, during the last few decades, the numbers of fossil fuel burning vehicle increased rapidly which increased the number of pollutants in the air .

Causes Of Air Pollution

Its causes include burning of fossil fuel and firewood, smoke released from factories , volcanic eruptions, forest fires, bombardment, asteroids, CFCs (Chlorofluorocarbons), carbon oxides and many more.

Besides, there are some other air pollutants like industrial waste, agricultural waste, power plants, thermal nuclear plants, etc.

Greenhouse Effect

The greenhouse effect is also the cause of air pollution because air pollution produces the gases that greenhouse involves. Besides, it increases the temperature of earth surface so much that the polar caps are melting and most of the UV rays are easily penetrating the surface of the earth.

Effects Of Air Pollution On Health

Moreover, it increases the rate of aging of lungs, decreases lungs function, damage cells in the respiratory system.

Ways To Reduce Air Pollution

Although the level of air pollution has reached a critical point. But, there are still ways by which we can reduce the number of air pollutants from the air.

Reforestation- The quality of air can be improved by planting more and more trees as they clean and filter the air.

Policy for industries- Strict policy for industries related to the filter of gases should be introduced in the countries. So, we can minimize the toxins released from factories.

Use of eco-friendly fuel-  We have to adopt the usage of Eco-friendly fuels such as LPG (Liquefied Petroleum Gas), CNG (Compressed Natural Gas), bio-gas, and other eco-friendly fuels. So, we can reduce the amount of harmful toxic gases.

To sum it up, we can say that the air we breathe is getting more and more polluted day by day. The biggest contribution to the increase in air pollution is of fossil fuels which produce nitric and sulphuric oxides. But, humans have taken this problem seriously and are devotedly working to eradicate the problem that they have created.

Above all, many initiatives like plant trees, use of eco-friendly fuel are promoted worldwide.

Water pollution: an introduction

by Chris Woodford . Last updated: October 1, 2023.

O ver two thirds of Earth's surface is covered by water ; less than a third is taken up by land. As Earth's population continues to grow, people are putting ever-increasing pressure on the planet's water resources. In a sense, our oceans, rivers , and other inland waters are being "squeezed" by human activities—not so they take up less room, but so their quality is reduced. Poorer water quality means water pollution .

We know that pollution is a human problem because it is a relatively recent development in the planet's history: before the 19th century Industrial Revolution, people lived more in harmony with their immediate environment. As industrialization has spread around the globe, so the problem of pollution has spread with it. When Earth's population was much smaller, no one believed pollution would ever present a serious problem. It was once popularly believed that the oceans were far too big to pollute. Today, with around 7 billion people on the planet, it has become apparent that there are limits. Pollution is one of the signs that humans have exceeded those limits.

What is water pollution?

Water pollution can be defined in many ways. Usually, it means one or more substances have built up in water to such an extent that they cause problems for animals or people. Oceans, lakes, rivers, and other inland waters can naturally clean up a certain amount of pollution by dispersing it harmlessly. If you poured a cup of black ink into a river, the ink would quickly disappear into the river's much larger volume of clean water. The ink would still be there in the river, but in such a low concentration that you would not be able to see it. At such low levels, the chemicals in the ink probably would not present any real problem. However, if you poured gallons of ink into a river every few seconds through a pipe, the river would quickly turn black. The chemicals in the ink could very quickly have an effect on the quality of the water. This, in turn, could affect the health of all the plants, animals, and humans whose lives depend on the river.

Photo: Pollution means adding substances to the environment that don't belong there—like the air pollution from this smokestack. Pollution is not always as obvious as this, however.

Thus, water pollution is all about quantities : how much of a polluting substance is released and how big a volume of water it is released into. A small quantity of a toxic chemical may have little impact if it is spilled into the ocean from a ship. But the same amount of the same chemical can have a much bigger impact pumped into a lake or river, where there is less clean water to disperse it.

"The introduction by man, directly or indirectly, of substances or energy into the marine environment (including estuaries) resulting in such deleterious effects as harm to living resources, hazards to human health, hindrance to marine activities, including fishing, impairment of quality for use of sea water and reduction of amenities." [1]

What are the main types of water pollution?

When we think of Earth's water resources, we think of huge oceans, lakes, and rivers. Water resources like these are called surface waters . The most obvious type of water pollution affects surface waters. For example, a spill from an oil tanker creates an oil slick that can affect a vast area of the ocean.

Photo: Detergent pollution entering a river—an example of surface water pollution. Photo courtesy of US Fish & Wildlife Service Photo Library.

Not all of Earth's water sits on its surface, however. A great deal of water is held in underground rock structures known as aquifers, which we cannot see and seldom think about. Water stored underground in aquifers is known as groundwater . Aquifers feed our rivers and supply much of our drinking water. They too can become polluted, for example, when weed killers used in people's gardens drain into the ground. Groundwater pollution is much less obvious than surface-water pollution, but is no less of a problem. In 1996, a study in Iowa in the United States found that over half the state's groundwater wells were contaminated with weed killers. You might think things would have improved since then, but, two decades on, all that's really changed is the name of the chemicals we're using. Today, numerous scientific studies are still finding weed killers in groundwater in worrying quantities: a 2012 study discovered glyphosate in 41 percent of 140 groundwater samples from Catalonia, Spain; scientific opinion differs on whether this is safe or not. [2]

Surface waters and groundwater are the two types of water resources that pollution affects. There are also two different ways in which pollution can occur. If pollution comes from a single location, such as a discharge pipe attached to a factory, it is known as point-source pollution . Other examples of point source pollution include an oil spill from a tanker, a discharge from a smoke stack (factory chimney), or someone pouring oil from their car down a drain. A great deal of water pollution happens not from one single source but from many different scattered sources. This is called nonpoint-source pollution .

When point-source pollution enters the environment, the place most affected is usually the area immediately around the source. For example, when a tanker accident occurs, the oil slick is concentrated around the tanker itself and, in the right ocean conditions, the pollution disperses the further away from the tanker you go. This is less likely to happen with nonpoint source pollution which, by definition, enters the environment from many different places at once.

Sometimes pollution that enters the environment in one place has an effect hundreds or even thousands of miles away. This is known as transboundary pollution . One example is the way radioactive waste travels through the oceans from nuclear reprocessing plants in England and France to nearby countries such as Ireland and Norway.

How do we know when water is polluted?

Some forms of water pollution are very obvious: everyone has seen TV news footage of oil slicks filmed from helicopters flying overhead. Water pollution is usually less obvious and much harder to detect than this. But how can we measure water pollution when we cannot see it? How do we even know it's there?

There are two main ways of measuring the quality of water. One is to take samples of the water and measure the concentrations of different chemicals that it contains. If the chemicals are dangerous or the concentrations are too great, we can regard the water as polluted. Measurements like this are known as chemical indicators of water quality. Another way to measure water quality involves examining the fish, insects, and other invertebrates that the water will support. If many different types of creatures can live in a river, the quality is likely to be very good; if the river supports no fish life at all, the quality is obviously much poorer. Measurements like this are called biological indicators of water quality.

What are the causes of water pollution?

Most water pollution doesn't begin in the water itself. Take the oceans: around 80 percent of ocean pollution enters our seas from the land. [16] Virtually any human activity can have an effect on the quality of our water environment. When farmers fertilize the fields, the chemicals they use are gradually washed by rain into the groundwater or surface waters nearby. Sometimes the causes of water pollution are quite surprising. Chemicals released by smokestacks (chimneys) can enter the atmosphere and then fall back to earth as rain, entering seas, rivers, and lakes and causing water pollution. That's called atmospheric deposition . Water pollution has many different causes and this is one of the reasons why it is such a difficult problem to solve.

With billions of people on the planet, disposing of sewage waste is a major problem. According to 2017 figures from the World Health Organization, some 2 billion people (about a quarter of the world's population) don't have access to safe drinking water or the most basic sanitation, 3.4 billion (60 people of the population) lack "safely managed" sanitation (unshared, with waste properly treated). Although there have been great improvements in securing access to clean water, relatively little, genuine progress has been made on improving global sanitation in the last decade. [20] Sewage disposal affects people's immediate environments and leads to water-related illnesses such as diarrhea that kills 525,000 children under five each year. [3] (Back in 2002, the World Health Organization estimated that water-related diseases could kill as many as 135 million people by 2020; in 2019, the WHO was still estimating the annual death toll from poor water and sanitation at over 800,000 people a year.) In developed countries, most people have flush toilets that take sewage waste quickly and hygienically away from their homes.

Yet the problem of sewage disposal does not end there. When you flush the toilet, the waste has to go somewhere and, even after it leaves the sewage treatment works, there is still waste to dispose of. Sometimes sewage waste is pumped untreated into the sea. Until the early 1990s, around 5 million tons of sewage was dumped by barge from New York City each year. [4] According to 2002 figures from the UK government's Department for the Environment, Food, and Rural Affairs (DEFRA), the sewers of Britain collect around 11 billion liters of waste water every day; there are still 31,000 sewage overflow pipes through which, in certain circumstances, such as heavy storms, raw sewage is pumped untreated into the sea. [5] The New River that crosses the border from Mexico into California once carried with it 20–25 million gallons (76–95 million liters) of raw sewage each day; a new waste water plant on the US-Mexico border, completed in 2007, substantially solved that problem. [6] Unfortunately, even in some of the richest nations, the practice of dumping sewage into the sea continues. In early 2012, it was reported that the tiny island of Guernsey (between Britain and France) has decided to continue dumping 16,000 tons of raw sewage into the sea each day.

In theory, sewage is a completely natural substance that should be broken down harmlessly in the environment: 90 percent of sewage is water. [7] In practice, sewage contains all kinds of other chemicals, from the pharmaceutical drugs people take to the paper , plastic , and other wastes they flush down their toilets. When people are sick with viruses, the sewage they produce carries those viruses into the environment. It is possible to catch illnesses such as hepatitis, typhoid, and cholera from river and sea water.

Suitably treated and used in moderate quantities, sewage can be a fertilizer: it returns important nutrients to the environment, such as nitrogen and phosphorus, which plants and animals need for growth. The trouble is, sewage is often released in much greater quantities than the natural environment can cope with. Chemical fertilizers used by farmers also add nutrients to the soil, which drain into rivers and seas and add to the fertilizing effect of the sewage. Together, sewage and fertilizers can cause a massive increase in the growth of algae or plankton that overwhelms huge areas of oceans, lakes, or rivers. This is known as a harmful algal bloom (also known as an HAB or red tide, because it can turn the water red). It is harmful because it removes oxygen from the water that kills other forms of life, leading to what is known as a dead zone . The Gulf of Mexico has one of the world's most spectacular dead zones. Each summer, according to studies by the NOAA , it typically grows to an area of around 5500–6500 square miles (14,000–16,800 square kilometers), which is about the same size as the state of Connecticut. [21]

Waste water

A few statistics illustrate the scale of the problem that waste water (chemicals washed down drains and discharged from factories) can cause. Around half of all ocean pollution is caused by sewage and waste water. Each year, the world generates perhaps 5–10 billion tons of industrial waste, much of which is pumped untreated into rivers, oceans, and other waterways. [8] In the United States alone, around 400,000 factories take clean water from rivers, and many pump polluted waters back in their place. However, there have been major improvements in waste water treatment recently. Since 1970, in the United States, the Environmental Protection Agency (EPA) has invested about $70 billion in improving water treatment plants that, as of 2021, serve around 90 percent of the US population (compared to just 69 percent in 1972). However, another $271 billion is still needed to update and upgrade the system. [15]

Factories are point sources of water pollution, but quite a lot of water is polluted by ordinary people from nonpoint sources; this is how ordinary water becomes waste water in the first place. Virtually everyone pours chemicals of one sort or another down their drains or toilets. Even detergents used in washing machines and dishwashers eventually end up in our rivers and oceans. So do the pesticides we use on our gardens. A lot of toxic pollution also enters waste water from highway runoff . Highways are typically covered with a cocktail of toxic chemicals—everything from spilled fuel and brake fluids to bits of worn tires (themselves made from chemical additives) and exhaust emissions. When it rains, these chemicals wash into drains and rivers. It is not unusual for heavy summer rainstorms to wash toxic chemicals into rivers in such concentrations that they kill large numbers of fish overnight. It has been estimated that, in one year, the highway runoff from a single large city leaks as much oil into our water environment as a typical tanker spill. Some highway runoff runs away into drains; others can pollute groundwater or accumulate in the land next to a road, making it increasingly toxic as the years go by.

Chemical waste

Detergents are relatively mild substances. At the opposite end of the spectrum are highly toxic chemicals such as polychlorinated biphenyls (PCBs) . They were once widely used to manufacture electronic circuit boards , but their harmful effects have now been recognized and their use is highly restricted in many countries. Nevertheless, an estimated half million tons of PCBs were discharged into the environment during the 20th century. [9] In a classic example of transboundary pollution, traces of PCBs have even been found in birds and fish in the Arctic. They were carried there through the oceans, thousands of miles from where they originally entered the environment. Although PCBs are widely banned, their effects will be felt for many decades because they last a long time in the environment without breaking down.

Another kind of toxic pollution comes from heavy metals , such as lead, cadmium, and mercury. Lead was once commonly used in gasoline (petrol), though its use is now restricted in some countries. Mercury and cadmium are still used in batteries (though some brands now use other metals instead). Until recently, a highly toxic chemical called tributyltin (TBT) was used in paints to protect boats from the ravaging effects of the oceans. Ironically, however, TBT was gradually recognized as a pollutant: boats painted with it were doing as much damage to the oceans as the oceans were doing to the boats.

The best known example of heavy metal pollution in the oceans took place in 1938 when a Japanese factory discharged a significant amount of mercury metal into Minamata Bay, contaminating the fish stocks there. It took a decade for the problem to come to light. By that time, many local people had eaten the fish and around 2000 were poisoned. Hundreds of people were left dead or disabled. [10]

Radioactive waste

People view radioactive waste with great alarm—and for good reason. At high enough concentrations it can kill; in lower concentrations it can cause cancers and other illnesses. The biggest sources of radioactive pollution in Europe are two factories that reprocess waste fuel from nuclear power plants : Sellafield on the north-west coast of Britain and Cap La Hague on the north coast of France. Both discharge radioactive waste water into the sea, which ocean currents then carry around the world. Countries such as Norway, which lie downstream from Britain, receive significant doses of radioactive pollution from Sellafield. [19] The Norwegian government has repeatedly complained that Sellafield has increased radiation levels along its coast by 6–10 times. Both the Irish and Norwegian governments continue to press for the plant's closure. [11]

Oil pollution

Photo: Oil-tanker spills are the most spectacular forms of pollution and the ones that catch public attention, but only a fraction of all water pollution happens this way. Photo by Lamar Gore courtesy of US Fish & Wildlife Service Photo Library and US National Archive .

When we think of ocean pollution, huge black oil slicks often spring to mind, yet these spectacular accidents represent only a tiny fraction of all the pollution entering our oceans. Even considering oil by itself, tanker spills are not as significant as they might seem: only 12 percent of the oil that enters the oceans comes from tanker accidents; over 70 percent of oil pollution at sea comes from routine shipping and from the oil people pour down drains on land. [12] However, what makes tanker spills so destructive is the sheer quantity of oil they release at once — in other words, the concentration of oil they produce in one very localized part of the marine environment. The biggest oil spill in recent years (and the biggest ever spill in US waters) occurred when the tanker Exxon Valdez broke up in Prince William Sound in Alaska in 1989. Around 12 million gallons (44 million liters) of oil were released into the pristine wilderness—enough to fill your living room 800 times over! Estimates of the marine animals killed in the spill vary from approximately 1000 sea otters and 34,000 birds to as many as 2800 sea otters and 250,000 sea birds. Several billion salmon and herring eggs are also believed to have been destroyed. [13]

If you've ever taken part in a community beach clean, you'll know that plastic is far and away the most common substance that washes up with the waves. There are three reasons for this: plastic is one of the most common materials, used for making virtually every kind of manufactured object from clothing to automobile parts; plastic is light and floats easily so it can travel enormous distances across the oceans; most plastics are not biodegradable (they do not break down naturally in the environment), which means that things like plastic bottle tops can survive in the marine environment for a long time. (A plastic bottle can survive an estimated 450 years in the ocean and plastic fishing line can last up to 600 years.)

While plastics are not toxic in quite the same way as poisonous chemicals, they nevertheless present a major hazard to seabirds, fish, and other marine creatures. For example, plastic fishing lines and other debris can strangle or choke fish. (This is sometimes called ghost fishing .) About half of all the world's seabird species are known to have eaten plastic residues. In one study of 450 shearwaters in the North Pacific, over 80 percent of the birds were found to contain plastic residues in their stomachs. In the early 1990s, marine scientist Tim Benton collected debris from a 2km (1.5 mile) length of beach in the remote Pitcairn islands in the South Pacific. His study recorded approximately a thousand pieces of garbage including 268 pieces of plastic, 71 plastic bottles, and two dolls heads. [14]

Alien species

Most people's idea of water pollution involves things like sewage, toxic metals, or oil slicks, but pollution can be biological as well as chemical. In some parts of the world, alien species are a major problem. Alien species (sometimes known as invasive species ) are animals or plants from one region that have been introduced into a different ecosystem where they do not belong. Outside their normal environment, they have no natural predators, so they rapidly run wild, crowding out the usual animals or plants that thrive there. Common examples of alien species include zebra mussels in the Great Lakes of the USA, which were carried there from Europe by ballast water (waste water flushed from ships ). The Mediterranean Sea has been invaded by a kind of alien algae called Caulerpa taxifolia . In the Black Sea, an alien jellyfish called Mnemiopsis leidyi reduced fish stocks by 90 percent after arriving in ballast water. In San Francisco Bay, Asian clams called Potamocorbula amurensis, also introduced by ballast water, have dramatically altered the ecosystem. In 1999, Cornell University's David Pimentel estimated that alien invaders like this cost the US economy $123 billion a year; in 2014, the European Commission put the cost to Europe at €12 billion a year and "growing all the time. [18]

Other forms of pollution

These are the most common forms of pollution—but by no means the only ones. Heat or thermal pollution from factories and power plants also causes problems in rivers. By raising the temperature, it reduces the amount of oxygen dissolved in the water, thus also reducing the level of aquatic life that the river can support. Another type of pollution involves the disruption of sediments (fine-grained powders) that flow from rivers into the sea. Dams built for hydroelectric power or water reservoirs can reduce the sediment flow. This reduces the formation of beaches, increases coastal erosion (the natural destruction of cliffs by the sea), and reduces the flow of nutrients from rivers into seas (potentially reducing coastal fish stocks). Increased sediments can also present a problem. During construction work, soil, rock, and other fine powders sometimes enters nearby rivers in large quantities, causing it to become turbid (muddy or silted). The extra sediment can block the gills of fish, effectively suffocating them. Construction firms often now take precautions to prevent this kind of pollution from happening.

What are the effects of water pollution?

Some people believe pollution is an inescapable result of human activity: they argue that if we want to have factories, cities, ships, cars, oil, and coastal resorts, some degree of pollution is almost certain to result. In other words, pollution is a necessary evil that people must put up with if they want to make progress. Fortunately, not everyone agrees with this view. One reason people have woken up to the problem of pollution is that it brings costs of its own that undermine any economic benefits that come about by polluting.

Take oil spills, for example. They can happen if tankers are too poorly built to survive accidents at sea. But the economic benefit of compromising on tanker quality brings an economic cost when an oil spill occurs. The oil can wash up on nearby beaches, devastate the ecosystem, and severely affect tourism. The main problem is that the people who bear the cost of the spill (typically a small coastal community) are not the people who caused the problem in the first place (the people who operate the tanker). Yet, arguably, everyone who puts gasoline (petrol) into their car—or uses almost any kind of petroleum-fueled transport—contributes to the problem in some way. So oil spills are a problem for everyone, not just people who live by the coast and tanker operates.

Sewage is another good example of how pollution can affect us all. Sewage discharged into coastal waters can wash up on beaches and cause a health hazard. People who bathe or surf in the water can fall ill if they swallow polluted water—yet sewage can have other harmful effects too: it can poison shellfish (such as cockles and mussels) that grow near the shore. People who eat poisoned shellfish risk suffering from an acute—and sometimes fatal—illness called paralytic shellfish poisoning. Shellfish is no longer caught along many shores because it is simply too polluted with sewage or toxic chemical wastes that have discharged from the land nearby.

Pollution matters because it harms the environment on which people depend. The environment is not something distant and separate from our lives. It's not a pretty shoreline hundreds of miles from our homes or a wilderness landscape that we see only on TV. The environment is everything that surrounds us that gives us life and health. Destroying the environment ultimately reduces the quality of our own lives—and that, most selfishly, is why pollution should matter to all of us.

How can we stop water pollution?

There is no easy way to solve water pollution; if there were, it wouldn't be so much of a problem. Broadly speaking, there are three different things that can help to tackle the problem—education, laws, and economics—and they work together as a team.

Making people aware of the problem is the first step to solving it. In the early 1990s, when surfers in Britain grew tired of catching illnesses from water polluted with sewage, they formed a group called Surfers Against Sewage to force governments and water companies to clean up their act. People who've grown tired of walking the world's polluted beaches often band together to organize community beach-cleaning sessions. Anglers who no longer catch so many fish have campaigned for tougher penalties against factories that pour pollution into our rivers. Greater public awareness can make a positive difference.

One of the biggest problems with water pollution is its transboundary nature. Many rivers cross countries, while seas span whole continents. Pollution discharged by factories in one country with poor environmental standards can cause problems in neighboring nations, even when they have tougher laws and higher standards. Environmental laws can make it tougher for people to pollute, but to be really effective they have to operate across national and international borders. This is why we have international laws governing the oceans, such as the 1982 UN Convention on the Law of the Sea (signed by over 120 nations), the 1972 London (Dumping) Convention , the 1978 MARPOL International Convention for the Prevention of Pollution from Ships , and the 1998 OSPAR Convention for the Protection of the Marine Environment of the North East Atlantic . The European Union has water-protection laws (known as directives) that apply to all of its member states. They include the 1976 Bathing Water Directive (updated 2006), which seeks to ensure the quality of the waters that people use for recreation. Most countries also have their own water pollution laws. In the United States, for example, there is the 1972 Clean Water Act and the 1974 Safe Drinking Water Act .

Most environmental experts agree that the best way to tackle pollution is through something called the polluter pays principle . This means that whoever causes pollution should have to pay to clean it up, one way or another. Polluter pays can operate in all kinds of ways. It could mean that tanker owners should have to take out insurance that covers the cost of oil spill cleanups, for example. It could also mean that shoppers should have to pay for their plastic grocery bags, as is now common in Ireland, to encourage recycling and minimize waste. Or it could mean that factories that use rivers must have their water inlet pipes downstream of their effluent outflow pipes, so if they cause pollution they themselves are the first people to suffer. Ultimately, the polluter pays principle is designed to deter people from polluting by making it less expensive for them to behave in an environmentally responsible way.

Our clean future

Life is ultimately about choices—and so is pollution. We can live with sewage-strewn beaches, dead rivers, and fish that are too poisonous to eat. Or we can work together to keep the environment clean so the plants, animals, and people who depend on it remain healthy. We can take individual action to help reduce water pollution, for example, by using environmentally friendly detergents , not pouring oil down drains, reducing pesticides, and so on. We can take community action too, by helping out on beach cleans or litter picks to keep our rivers and seas that little bit cleaner. And we can take action as countries and continents to pass laws that will make pollution harder and the world less polluted. Working together, we can make pollution less of a problem—and the world a better place.

What is Environmental Pollution?

The phenomenon of undesirable changes in the surroundings that are harmful to animals and plants, and leads to environmental degradation is known as environmental pollution. These changes can occur because of the solid, liquid or gaseous pollutants. For example, DDT, plastic, and heavy materials take more time to degrade and are known as notable pollutants. For the determination of risk assessment of public health, concentration of pollutants is measured.

Essay on Environmental Pollution – 100 Words 

The presence of contaminants in the environment is referred to as pollution. Gases like Carbon Dioxide (CO2) and Carbon Monoxide (CO), among others; solid pollutants like plastic, sewage, etc.; and chemicals like fertilisers, as well as those produced as byproducts in manufacturing, transportation, etc., are a few examples of polluting substances.

The immediate result of pollution is that it makes the world’s natural resources useless or toxic to use, as well as leads to the extinction of species and ecological imbalance. To stop more harm from occurring to the earth and its inhabitants due to environmental pollution, it is imperative to take proactive precautions.

Essay on Environmental Pollution – 250 Words 

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.

Essay on Environmental Pollution – 500 Words 

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.

Essay on Pollution in 100 Words

Pollution is a grave issue as harmful substances and pollutants contaminate the environment, causing harm to living organisms and ecosystems. It exists in various forms, including air, water, soil, and noise pollution.

Air pollution occurs due to the release of harmful gases and particles into the atmosphere from industrial activities and vehicles. Water pollution happens when industrial waste, sewage, and chemicals enter water bodies. Soil pollution results from the infiltration of toxins into the soil, affecting plant growth and the food chain. Noise pollution refers to excessive noise levels that disrupt human well-being.

To address pollution, stricter regulations and sustainable practices are necessary. Individuals must conserve resources, manage waste responsibly, and adopt eco-friendly habits.

Essay on Pollution in 200 Words

Pollution has become a critical issue in today’s world as harmful substances and pollutants are introduced into the environment, causing detrimental effects on living organisms and ecosystems. Various forms of pollution exist, including air pollution, water pollution, soil pollution, and noise pollution.

Air pollution occurs when harmful gases and particulate matter are released into the atmosphere, primarily from industrial activities and vehicular emissions. These pollutants degrade air quality and pose risks to human health, leading to respiratory problems and allergies.

Water pollution is the contamination of water bodies such as rivers, lakes, and oceans due to the discharge of industrial waste, sewage, and chemicals. It affects aquatic life and poses significant risks to human health, as consuming or using polluted water can lead to various waterborne diseases.

Soil pollution arises when harmful chemicals or toxins seep into the soil, affecting plant growth and the overall health of the ecosystem. Contaminated soil also has adverse effects on the food chain, as plants and crops absorb these pollutants, which can then transfer to animals and humans upon consumption.

Noise pollution refers to excessive noise levels that disrupt the peace and well-being of human beings and wildlife. Sources include construction activities, transportation, industrial machinery, and loud music. Prolonged exposure to high levels of noise can lead to stress, hearing loss, and other health issues.

Environmental Changes Are Fueling Human, Animal and Plant Diseases, Study Finds

Biodiversity loss, global warming, pollution and the spread of invasive species are making infectious diseases more dangerous to organisms around the world.

By Emily Anthes

Several large-scale, human-driven changes to the planet — including climate change, the loss of biodiversity and the spread of invasive species — are making infectious diseases more dangerous to people, animals and plants, according to a new study.

Scientists have documented these effects before in more targeted studies that have focused on specific diseases and ecosystems. For instance, they have found that a warming climate may be helping malaria expand in Africa and that a decline in wildlife diversity may be boosting Lyme disease cases in North America.

But the new research, a meta-analysis of nearly 1,000 previous studies, suggests that these patterns are relatively consistent around the globe and across the tree of life.

“It’s a big step forward in the science,” said Colin Carlson, a biologist at Georgetown University, who was not an author of the new analysis. “This paper is one of the strongest pieces of evidence that I think has been published that shows how important it is health systems start getting ready to exist in a world with climate change, with biodiversity loss.”

In what is likely to come as a more surprising finding, the researchers also found that urbanization decreased the risk of infectious disease.

The new analysis, which was published in Nature on Wednesday, focused on five “global change drivers” that are altering ecosystems across the planet: biodiversity change, climate change, chemical pollution, the introduction of nonnative species and habitat loss or change.

The researchers compiled data from scientific papers that examined how at least one of these factors affected various infectious-disease outcomes, such as severity or prevalence. The final data set included nearly 3,000 observations on disease risks for humans, animals and plants on every continent except for Antarctica.

The researchers found that, across the board, four of the five trends they studied — biodiversity change, the introduction of new species, climate change and chemical pollution — tended to increase disease risk.

“It means that we’re likely picking up general biological patterns,” said Jason Rohr, an infectious disease ecologist at the University of Notre Dame and senior author of the study. “It suggests that there are similar sorts of mechanisms and processes that are likely occurring in plants, animals and humans.”

The loss of biodiversity played an especially large role in driving up disease risk, the researchers found. Many scientists have posited that biodiversity can protect against disease through a phenomenon known as the dilution effect.

The theory holds that parasites and pathogens, which rely on having abundant hosts in order to survive, will evolve to favor species that are common, rather than those that are rare, Dr. Rohr said. And as biodiversity declines, rare species tend to disappear first. “That means that the species that remain are the competent ones, the ones that are really good at transmitting disease,” he said.

Lyme disease is one oft-cited example. White-footed mice, which are the primary reservoir for the disease, have become more dominant on the landscape, as other rarer mammals have disappeared, Dr. Rohr said. That shift may partly explain why Lyme disease rates have risen in the United States. (The extent to which the dilution effect contributes to Lyme disease risk has been the subject of debate, and other factors, including climate change, are likely to be at play as well.)

Other environmental changes could amplify disease risks in a wide variety of ways. For instance, introduced species can bring new pathogens with them, and chemical pollution can stress organisms’ immune systems. Climate change can alter animal movements and habitats, bringing new species into contact and allowing them to swap pathogens .

Notably, the fifth global environmental change that the researchers studied — habitat loss or change — appeared to reduce disease risk. At first glance, the findings might appear to be at odds with previous studies, which have shown that deforestation can increase the risk of diseases ranging from malaria to Ebola. But the overall trend toward reduced risk was driven by one specific type of habitat change: increasing urbanization.

The reason may be that urban areas often have better sanitation and public health infrastructure than rural ones — or simply because there are fewer plants and animals to serve as disease hosts in urban areas. The lack of plant and animal life is “not a good thing,” Dr. Carlson said. “And it also doesn’t mean that the animals that are in the cities are healthier.”

And the new study does not negate the idea that forest loss can fuel disease; instead, deforestation increases risk in some circumstances and reduces it in others, Dr. Rohr said.

Indeed, although this kind of meta-analysis is valuable for revealing broad patterns, it can obscure some of the nuances and exceptions that are important for managing specific diseases and ecosystems, Dr. Carlson noted.

Moreover, most of the studies included in the analysis examined just a single global change drive. But, in the real world, organisms are contending with many of these stressors simultaneously. “The next step is to better understand the connections among them,” Dr. Rohr said.

Migraine shame is real. My pain is not ‘just’ a headache.

My migraine attacks are chronic and cause me debilitating pain. Why am I so embarrassed to tell people about them?

About 40 million Americans get migraines. They can be so debilitating that sufferers miss work for days. There is no cure.

But many migraine patients like me are embarrassed to tell friends, co-workers and even relatives when they experience an attack. Why do I feel ashamed of having inherited a common neurological disorder?

Some of us fear that if we complain of a migraine, we’ll be suspected of feigning impairment to get out of work or some social obligation. I grew up with a well-worn stereotype: a woman avoiding sex with her husband, by pleading, “Not tonight, dear. I have a headache.”

I’d bet most of us who suffer from migraine attacks don’t fake being ill. We fake being well.

Three out of 4 migraine sufferers are women. For most of the last century, migraine was considered psychosomatic, a complaint of overwhelmed and neurotic women who couldn’t cope with life.

In her 1968 essay “In Bed,” Joan Didion put words to the humiliation of migraine, calling it her “shameful secret.” She spent “one or two days a week almost unconscious with pain, … evidence not merely of some chemical inferiority but of all my bad attitudes, unpleasant tempers, wrongthink.”

I learned as a child that even people who love you can have trouble mustering sympathy. My grandmother lived with us when I was growing up. When she complained of headaches, my mother rolled her eyes, never believing Grandma’s pain was real.

Although my migraine attacks are chronic, I almost never let one keep me from a social event or work. I may be pale, inarticulate and unfocused, but too embarrassed to let on why. I fear the reaction would be, “It’s just a headache!”

Migraine is, in fact, not just a headache. It can consist of a panoply of symptoms — and sometimes no headache at all.

Living with migraines

My most severe migraine struck me nine years ago on a trip my husband and I took to India. I knew I was in trouble when I saw the vision-distorting “aura” of squiggly lines that forewarns searing head pain. Soon I was vomiting every few minutes and felt like the light from my bedside lamp was piercing my eyes. By the time the hotel doctor arrived, I was clutching a pillow and howling.

The doctor gave me dexamethasone, a corticosteroid my American doctors had occasionally prescribed for intractable migraines, the ones that colonized my brain for up to three days. It enabled me to fall asleep. I woke up the next morning giddy at feeling pain free.

Still, some “migraineurs” feel disbelieved. As a young doctor, Michael Cutrer, a neurologist at Mayo Clinic in Rochester, Minn., who specializes in headaches, said he saw some of his colleagues downplay the severity of migraine attacks. “The impact of a lot of head disorders is underestimated by everyone except the person having it,” he said.

While no one knows for sure what causes migraines, there are seemingly endless possible triggers. Some — like heat, cold, weather changes, fluctuating hormones and stress — are unavoidable.

Each migraine patient has their own unique list. Mine includes dehydration, too little sleep, missed meals, alcohol and chocolate, hot stuffy rooms, strobe lights and certain smells, mainly perfume.

When I wake up with a headache, I review a mental checklist of ways I can blame myself for my throbbing brain. Did I eat something I shouldn’t have, a potential trigger I didn’t know was on my list, say tomatoes, potato chips or peanuts? Did I stay up too late or not drink enough water?

Migraine avoidance precludes spontaneity. I have to stick to a regular meal schedule, sleep enough, but not too much, abstain from alcohol and have just the right amount of caffeine (not too much or too little) and skip plays or concerts with strobe lights or loud sound effects.

After puberty, my migraines were often triggered by hormone fluctuations, so I hoped I would be one of the many women whose attacks end at menopause.

Unfortunately, mine got a lot worse when I turned 50. I woke up with nausea and stabbing head pain several times a week.

Few treatment options for migraines

When I first started seeing headache specialists in about 1990, I was astonished to learn there were no drugs developed to prevent migraine. Over-the-counter pain relievers offered no relief. So for about 20 years, I was prescribed off-label drugs created to treat everything from seizures to an irregular heartbeat. Most had side effects. None prevented my migraines.

The introduction of triptans (such as Imitrex, Maxalt and Zomig) as a treatment in the 1990s was a breakthrough for me. But there was a catch — the risk of “medication overuse.” If taken more than two days a week, triptans can trigger rebound headaches. Even though I was getting three to four migraines a week, my insurance company would only dispense nine pills every 28 days, leaving me with nothing to take when I invariably ran out.

When I asked my then-neurologist what to do, she simply shrugged. Stunned, I felt abandoned by the one person who was supposed to understand what I was going through.

In 2010, Botox was approved by the Food and Drug Administration for preventing chronic migraines, and I was lucky to have a neurologist who prescribed it and an insurance plan that paid for it. Since then, I submit to 31 Botox injections in my forehead, neck and skull every 10 weeks or so. Botox has actually reduced the frequency and intensity of my migraines, but my skeptical friends are convinced I’ve figured out a scam to get free wrinkle treatments.

In 2018, the first treatment invented to prevent migraine, Aimovig, was approved by the FDA.

It took about two years to get my insurance company to cover a similar formulation, Emgality, which costs more than $800 per injection out of pocket. Now I suffer from about two migraine attacks a week, which may not seem like much progress, but it feels as life-changing to me as winning the lottery.

There are now several new medications on the market, endorsed by celebrities such as Serena Williams, Aly Raisman, Khloe Kardashian and Lady Gaga.

I wonder if celebrities going public about migraines will help erode the stigma, but I suspect progress will come slowly.
