Essay on Air Pollution

When impurities generated due to human activities, get mixed with the air we breathe so as to cause health issues, it is termed as air pollution. The effects of air pollution on humans and on the environment are various, just as the causes of air pollution are. Air pollution occurs mainly due to anthropogenic sources, which is due to human activities.

Effects of Air Pollution - Essay 1 (250 Words)


Air Pollution refers to the introduction of unwanted and hazardous substances into the environmental air; thereby, making the air unhealthy to breathe. These pollutants could be in the form of gases or vary fine solid particles.

Air Pollution Effects

There are several effects of air pollution on the environment. Some of these prominent effects are listed below.

  • Smog

Smog is a term used to refer to the combined state of smoke and fog. It is a common occurrence in cities with heavy vehicular traffic, during winter months. Thick smoke emanated from the vehicles gets mixed with already existing fog, to give a dense mixture called smog. It has a tendency to persist in the atmosphere for days. Smog is also very harmful to health and causes respiratory ailments in humans.

  • Greenhouse Effect

Greenhouse effect is caused by the greenhouse gases produced mainly by the combustion of fossil fuel. Some greenhouse gases like Carbon dioxide (CO2) and Sulphur dioxide (SO2), etc, form a kind of blanket over the earth’s atmosphere, preventing the surface heat to escape. This automatically results in heating up of the earth's surface, termed as ‘Global Warming’.


How severe the effects of air pollution may be, there is always a solution to deal with the problem right where it is generated. That is, air pollution should be controlled by effectively preventing the production of potential pollutants due to anthropogenic or human activities. Reducing the use of fossil fuel, saving electricity, managing waste are some of the noble steps that could be taken to prevent air pollution.

Prevention of Air Pollution - Essay 2 (400 Words)


Air Pollution has become a global concern that must be immediately addressed. There are many measures that could be taken at local and higher levels to prevent any further pollution of the air. In this essay, we will go through the preventive measures to be taken to prevent air pollution.

Prevention of Air Pollution

As ‘Charity begins from home’; the effort to prevent air pollution can also be initiated from home. The methods to prevent air pollution are listed below.

  • Save Energy

Energy conservation is the least you can do to clean the air surrounding you. When you switch off an unnecessary bulb or other electric equipment, you contribute in lowering down the demand for electricity. With reduced demand, the electricity production units will naturally decrease their fossil fuel consumption, thereby, making the air cleaner.

  • Use Public Transport

Transport industry is a major contributor to air pollution. Many metropolitan cities around the world have to face emergency like situation, due to a large number of transport vehicles oozing out tons of gases from the exhaust. If you chose to take public transport, you would not be only easing out the roads but also making the air cleaner.

  • Reduce the Burning of Wood

You might be burning wood or other fuels in your house for heating water, cooking food or other purposes. This domestic burning of fossil fuel emits harmful toxic gases directly into the atmosphere. Avoiding using wood, coal and other fuel will considerably reduce air pollution.

  • Waste Management

Proper waste management must be put in force to tackle air pollution. Improper and large scale dumping of garbage results in small and large landfills, which emit hazardous gases upon degradation of waste. If the waste is effectively collected from the source and disposed of properly, landfills wouldn’t be formed and the air would be cleaner.

  • Keep Your Vehicle Toned

Vehicles that are poorly maintained emit more quantities of exhaust gases than the vehicles that are serviced from time to time. It is therefore advisable to service your vehicle from time to time so that it did not pollute the air and degrades the environment.


Air pollution is though widespread, could still be prevented, if only we take simple measures in the right direction. Some simple decisions like reducing electricity use, better waste disposal can bring wonderful changes in the environment.

Causes and Effects of Air Pollution - Essay 3 (600 Words)


‘Air Pollution’ refers to the contamination of environmental air by various kinds of pollutants. These pollutants are mainly generated due to human activities; though, there are also some natural sources.

Causes of Air Pollution

The main cause of air pollution is the burning of fossil fuel by humans. Burning of fossil fuel releases hazardous gases like Carbon Monoxide (CO) or Sulphur Dioxide (SO2), etc. Some of the main sources of air pollution are listed below:

  • Industries

Modern industries like manufacturing industries, coal industries, or any other type of industry that uses or produces fossil fuel are the main source of air pollution. Burning of fossil fuel releases hazardous gases like Carbon Dioxide (CO2), Methane (CH4) and Nitrous Oxide (N2O), etc. These gases are directly released into the atmosphere, thereby polluting the air.

  • Transportation

Transportation industry relies mainly on fossil fuel. Irrespective of land, air or water transport, fuel is the main source of power behind the vehicles. Trucks, cars, bikes, buses, aircrafts, and sea liners, etc. burn fossil fuel to power their movement; thereby, generating gases like Carbon dioxide (CO2), Nitrous Oxide (N2O) and Methane (CH4).

  • Agriculture Industry

Sometimes, the agricultural industry follows the practice of controlled burning to clear an area from crop residue and to get it ready for the next crop season. It is also termed as stubble burning to clear off the straw stubble that remains after harvest. Sometimes, this activity is carried out on such a large scale that it fills a large part of the atmosphere with smoke, making the air harmful to breathe.

  • Landfills

Landfills are also the main source of air pollution. Huge garbage dumps, when decomposing slowly releases Methane (CH4) into the atmosphere, which is an asphyxiant. It reduces the concentration of oxygen in the atmosphere, thereby, increasing the chances of suffocation.

  • Wildfires

Sometimes, naturally occurring wildfires can also be a potent source of air pollution. Uncontrolled and large scale forest fires can release a large amount of smoke and gases like Carbon Monoxide (CO) and others.

  • Volcanic Activities

Volcanoes are also a potent source of air pollution; though their effect is only limited to a particular area. Volcanic activities throw dust from the mouth of the volcano to thousands of feet in the atmosphere. This dust gets mixed with the air and pollutes it. Sulfur and chlorine also get released during the volcanic activities.

Effects of Air Pollution

  • Health Effects

Air pollution has a significant effect on the health of those who are exposed to it. Several types of respiratory infections and heart diseases are linked to air pollution. Children, who are exposed to polluted air from an early age, possess the risk of developing asthma at a comparatively young age.

  • Reduced Crop Yield

Air pollution has also been studied for its effect on crop yield over a particular area. It was found that the crop yield in the area affected by air pollution is considerably reduced.

  • Economical Loss

Every year air pollution results in millions of premature deaths throughout the world. According to a study, one in ten deaths in the developing countries is caused due to air pollution-related effects. These deaths are nothing but loss of productivity, which puts the nation’s growth on the back foot.


Air pollution is one of the major issues that the world needs to collectively deal with. Unless the required policy measures are taken to clean the air for ourselves as well as for the future generation, it wouldn’t be possible to grow and prosper. Apart from taking policy measures, there is also a need to raise awareness of the general public on the matter of air pollution.
