Question

Mention the human activities that lead to air pollution.

Answer 1

Hint: Air pollution refers to the release of pollutants into the air that are detrimental to human health and the planet as a whole. This is due to the air pollutants. Pollutants here mentioned, are those agents that bring about an undesirable change in the environment.

Complete Answer:
The human activities that leads to the release of air pollutants in the atmosphere causing air pollution are as follows:
1) Burning of fossil fuels in automobiles industries and households: Generally in all the industries you can see a black smoke coming out of the long pipes in the outer environment directly released into the air. It is causing the air pollution to a great extent. They release a large amount of carbon monoxide, hydrocarbons, organic compounds, and chemicals into the air thereby depleting the quality of air.
The automobiles that we use, also releases smoke due to the burning of petrol and diesel and hence we (the vehicle users) are also responsible for this harmful environment.
Sulphur dioxide is the name of that harmful gas released by the burning of fossil fuels like coal, petroleum which is one of the major causes of air pollution.
2) Smokestacks of thermal power plants smelters and Other industries release particulate and other gaseous pollutants together with harmless gases like nitrogen and oxygen.
3) Decomposition of garbage into open air also leads to air pollution.
4) Mining operations: Mining is a process in which the minerals present below the earth are extracted. During this process dust and chemicals are released in the air causing massive air pollution.

Note: Effect of this type of air pollution due to human activities is deadly.
It can cause internal injury to all the living organisms and affect the respiratory system. It can also reduce the growth rate and the yield of crops. Now, the effect of air pollution is such that it is causing the premature death of plants.
And thereby, after looking at all these consequences we should realize that we should stop the unnecessary causes of air pollution to bring out a healthy environment around us so that everybody could get pollution free fresh air to breathe in.
