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.

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.

What is air pollution?

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

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

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

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

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

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

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

Smog and soot

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

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

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

Hazardous air pollutants

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

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

Greenhouse gases

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

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

Pollen and mold

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

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

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

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

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

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

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

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

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

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

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

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

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

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

Air Pollution Sources, Effects and Ways of Minimizing Definition Essay

Introduction, air pollution, sources of air pollution, classification of air pollutants, works cited.

Generally, pollution is the process of introducing new materials, contaminants, into the natural environment leading to adverse effects. There are different types of pollution. These include air pollution, sound pollution, light pollution, littering, and soil contamination.

From the above definition of pollution, it is clear that pollutants are foreign substances and particles that contaminate the environment. This paper discusses the various sources of air pollution, the effects of air pollution, and ways of minimizing air pollution. The paper also discusses two classes of pollutants: indoor pollutants and outdoor pollutants.

Air pollution is the process of introducing pollutants into the atmosphere willingly or unwillingly. Human beings perform certain activities that lead to air pollution. For instance, the burning of bushes leads to air pollution. When pollutants enter the atmosphere, they pollute it. Examples of these pollutants include commercial chemicals, foreign particles, and biological substances. After entering the atmosphere, they become part of the atmosphere and they mix with air components.

These pollutants are dangerous especially if living organisms inhale them. They can cause diseases, death of living organisms such as plants and animals, deterioration of the natural environment, and uneasiness. In other words, the introduction of unwanted materials into the atmosphere is a dangerous phenomenon. Air pollutants can also cause other problems. For example, they can damage the built environment and ecosystems of living organisms (Gay 3-14).

According to scientists, the atmosphere is an intricate innate gaseous system that is so much beneficial to all living organisms—plants and animals. In fact, a clean atmosphere supports life on earth. This is the reason why all human beings should stop activities that lead to the contamination of the atmosphere.

Most importantly, scientists across the globe continue to warn people that the stratospheric ozone depletion is dangerous, and can cause health hazards. Undoubtedly, when air pollutants enter the atmosphere, they destroy the ozone layer. The depletion of the ozone layer means that earth’s ecosystems will suffer.

According to research, air pollution is common in urban areas due to many vehicles that emit fumes to the atmosphere. Moreover, in urban areas, many factories release dangerous gases to the atmosphere leading to air pollution.

In rural areas, the burning bushes and lighting of unnecessary fire also causes air pollution. In rural areas where farming is a common activity, farmers pollute the atmosphere by spraying chemicals to food crops. Notably, since the earth is the only planet that supports life, it is necessary to avoid activities that cause air pollution.

Therefore, all human beings should take into consideration the effects of their activities, especially those that cause air pollution. Moreover, people should understand that although economic activities are good for their welfare, they can survive for few days without food, but they cannot survive even a second minus oxygen. This is the main reason why people should avoid all activities that contaminate the atmosphere.

Many people do not understand the importance of keeping the environment clean and free from any contamination. Perhaps this is the main reason why many of them engage in activities that contaminate the environment. For instance, the exploitation of natural resources and industrialization can emit dangerous gases into the atmosphere.

Additionally, green house gases also emit dangerous gases to the atmosphere. For example, green house gases such as sulfur trioxide and carbon dioxide are some of the dangerous gases that enter the atmosphere. Definitely, the destruction of the atmosphere is a serious issue of concern to many people, as the contamination of the atmosphere causes serious health hazards. Undeniably, air pollution is one of the problems facing the world today.

The challenge of air pollution started during the industrial revolution age. During those times, many people did not understand the effects of contaminating the atmosphere. There is no doubt that industrial revolution brought significant developments such as improved means of transport, cheaper merchandise, and the improvement of life.

However, the development of technology came at a price. For example, the construction of many factories has increased the percentage of dangerous gases in the atmosphere. However, due to increase of knowledge, many people are now aware of the causes and dangers of air pollution.

For example, automobiles burn gasoline thus emitting dangerous gasses to the atmosphere. In addition, the incineration of products also emits dangerous gases to the atmosphere. Furthermore, smoke from factories also emits dangerous particles and gases into the atmosphere that is dangerous to the life of living organisms.

In fact, the main reason why air pollution is more dangerous than other forms of pollution is that it involves the depletion of the ozone layer, which supports life on earth. For instance, gaseous by-products from industries can cause death of organisms once they inhale contaminated air. Therefore, as the world becomes more industrialized, there will be continued air pollution and increased health hazards.

In some instances, air pollution can occur from natural sources, which are beyond the control of human beings. For example, the destruction of forest by fire causes leads to air pollution. The eruption of volcanoes and dust storms are also other examples of natural air pollutants. In some cases, the polluted air combines with raindrops to form acid rain, which is another form of air pollution.

The effects of acid rain are catastrophic and they include the annihilation of crops, erosion of buildings, and destruction of other assets. Moreover, acid rain can also cause global warming, which is one of the very many issues affecting the world today. According to scientists, air pollution leads to climate change, and that people will soon start noticing climate change patterns and alterations. If there is continued air pollution, the average global temperature will rise and this will increase health hazards and respiratory deaths.

Of course, the two major classes of causes of air pollutants are indoor and outdoor. In the former, we have a number of pollutants that emit dangerous gases to the atmosphere.

For example, furnishings and cleaners are examples of indoor pollutants. Mold is also another indoor air pollutant that is very dangerous. To start with, mold is a microscopic organism common on surfaces with high humidity percentages. For instance, on the body of human beings, mold can grow into the skin and cause health implications, asthma and allergic reactions.

Recently, scientists have also associated mold with chronic sinus infections that is not only dangerous, but can also cause death of organisms. Additionally, mold can cause breathing difficulties, breeding from the lungs. It can also cause memory loss and hearing impairments. Clearly, indoor pollutants are dangerous. However, as compared to outdoor pollutants, they are minimal (Farrah and Brook 1240-1241).

Ordinarily, outdoor pollutants are common in the atmosphere, which contains the air that living organisms inhale. Pollutants from industries, automobiles, airplanes, and other machines emit fissile fuels into the air. These are some of the examples of outdoor air pollutants. Different factories, depending on what they manufacture, emit different gases to the atmosphere. Moreover, some factories release sulfuric acid fumes to the atmosphere, which can cause respiratory difficulties.

When it is raining, the raindrops combine with these fumes to form acid rain that is dangerous to the life of living organisms, and destruction of property especially in the northern hemisphere region. In northern lakes, organisms living in water such as fish die due to acid rain. Ironically, the solution to this predicament is quite involving and expensive, as it is not easy to clear sulfur from coal due to burning. However, it is easier to clear carbon dioxide from the air as compared to other gases.

Statistics indicate that carbon dioxide is the most abundant air pollutant in the atmosphere compared to chlorofluorocarbons such as nitrogen oxide and sulfur oxide from green houses. This is due to rampant deforestation and release of fossil fuels into the atmosphere. Nevertheless, green plants help in clearing carbon dioxide from the atmosphere (Tyson 57-77).

Many countries have come together to enact laws that will protect the environment for future generations. From the Kyoto Protocol to the Clean Air Act, countries across the globe continue to adopt laws that will govern the protection of the environment.

However, adopting laws is not enough, as countries must commit themselves to protecting the environment. For example, the development of electric vehicles will reduce emission of fossil gases to the atmosphere. Factories should also use resources that emit fewer gases to the atmosphere.

For example, in the place of coal they can use natural gas, which emits les gas. Motorists should also turn-off their engines in order to reduce more gas emissions into the atmosphere. Although the world has made progressive advances towards a clean atmosphere, industrial development remains the biggest hindrance. Nevertheless, many countries have pledged to reduce gas emissions in order to protect the atmosphere from contamination for future generations.

Effects of Air Pollution

Air pollution affects all things. It is harmful to our health, and it impacts the environment by reducing visibility and blocking sunlight, causing acid rain, and harming forests, wildlife, and agriculture. Greenhouse gas pollution, the cause of climate change, affects the entire planet.

Harming Human Health

According to the World Health Organization , an estimated seven million people die each year from air pollution. More than 4,000 people died in just a few months due to a severe smog event that occurred in London in 1952. Ground-level ozone causes muscles in the lungs to contract, making it difficult to breathe. Exposure to high ozone levels can cause sore throat, coughing, lung inflammation, and permanent lung damage.

Symptoms from short-term exposure typically resolve quickly, but long term exposure is linked to serious illness and disease in multiple body systems. Children, the elderly, and people with ongoing illnesses are more vulnerable to air pollution than other groups. Urban populations are also at greater risk due to high concentrations of pollution within cities. Check the current air quality in your area to determine if you should take precautions such as reducing or avoiding outdoor activity.

Harming Animals and Plants

Wildlife can experience many of the same negative health effects of air pollution that humans do. Damage to respiratory systems is the most common effect on animals, but neurological problems and skin irritations are also common.

Plants and crops grow less when exposed to long-term air pollution. Ozone pollution harms plants by damaging structures called stomata, which are tiny pores on the underside of leaves that allow the plant to "breathe." Some types of plants can protect themselves by temporarily closing their stomata or producing antioxidants, but others are particularly sensitive to damage. Between 1980 and 2011, nine billion dollars-worth of soybeans and corn were lost in the US as a result of ozone pollution. When acid rain, lead toxicity, and exposure to nitrogen oxides change the chemical nature of the soil, plants are robbed of the nutrients that they need to grow and survive. This impacts agriculture, forests, and grasslands.

There are many other ways that air pollution affects living things, such as damaging the habitat, water, and food sources that plants and animals need to survive.

Causing Acid Rain

Burning fossil fuels releases sulfur and nitrogen oxides into the atmosphere. Acid rain forms when sulfur dioxide and nitrogen dioxide mix with water droplets in the atmosphere to make sulfuric acid and nitric acid. Winds can carry these pollutants for thousands of miles, until they fall to the Earth's surface as acid rain, which damages the leaves of vegetation, increases the acidity of soils and water, and is linked to over 500 deaths each year. Buildings and other structures are also impacted by acid rain, which causes an estimated five billion dollars of property damage each year. Acid rain dissolves mortar between bricks, causes stone foundations to become unstable, and is destroying ancient buildings and statues carved from marble and limestone.

Reducing Sunlight

High levels of particulate pollution from all types of burning reduces the amount of sunlight that reaches the surface and even changes  the appearance of the sky . When less sunlight is available for photosynthesis, forests grow at a slower rate and crops are less productive. Hazy skies not only reduce visibility, but also impact the weather and even the climate .

Making a Hole in the Ozone Layer

In 2019 the ozone hole over Antarctica (shown in blue) was the smallest it has been since the hole was discovered. Since the banning of CFCs, the ozone hole continues to shrink, but scientists warn that complete recovery is still uncertain.

The hole in the ozone layer is caused by air pollutants . Chemicals used as refrigerants, such as chlorofluorocarbons (CFCs), contain chlorine atoms. Releasing chlorine atoms into the atmosphere destroys ozone. A single chlorine atom can destroy thousands of ozone molecules. The ozone layer blocks harmful ultraviolet-C (UVC) and ultraviolet-B (UVB) radiation from the Sun — it protects us in a way that is similar to putting sunscreen on your skin to prevent sunburn. The ozone hole puts all living things at risk by increasing the amount of ultraviolet radiation that reaches the surface. Exposure to this radiation increases the risk of skin cancer in humans, restricts growth and development in plants, slows the development of fish and amphibians, and reduces the number of phytoplankton in marine ecosystems. It also causes natural and synthetic materials to breakdown at an accelerated rate.

Adding Too Much Nitrogen to the Land

Gaseous ammonia (NH3) from agriculture and nitrogen dioxide (NO2) from car, truck, and airplane emissions increase the amount of nitrogen in soils. Plants need nitrogen to grow, but too much nitrogen can limit the growth of some plants and increase the growth of others, disrupting the balance of species within an ecosystem. This disruption is negatively impacting grasslands and other fragile environments around the world.

Effects of Greenhouse Gas Pollution

Greenhouse gas pollution is causing climate change. As a result, ecosystems are changing faster than plants and animals can adapt, and many species are going extinct. Marine ecosystems are vulnerable to ocean acidification caused when carbon dioxide emitted into the atmosphere is dissolved in seawater. Ocean acidification makes it difficult for many marine species to grow shells and skeletons.

Melting ice sheets, warming oceans, and extreme weather conditions are examples of how climate changes caused by greenhouse gas pollution threaten ecosystems across the Earth. In many cases, the decline of one or a few species due to air pollution can topple the balance of entire ecosystems.
