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.
Pollutants
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.
Conclusion
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.
