Earlier, the air that we used to breathe was fresh and pure, but these days that air had got contaminated by toxic pollutants. And this is what is air pollution. Due to the increase in factories and industrialization, the concentration of poisonous gases has increased in the atmosphere. In addition to this, the burning of fossil fuels and deforestation also adds to the toxic substances in the air.

There are many causes of air pollution. The burning of fossil fuels, smoke released from factories, volcanic eruptions, forest fires, CFCs, carbon oxides are all the major reasons behind our air getting contaminated. Apart from these reasons, industrial waste, agricultural waste have also added up to air pollution.

The fossil fuels that are burned in the environment produce oxides of carbon that are harmful to the environment. Earlier, there used to be many trees which man has cut down now for their selfish reasons. People cut down trees for building factories, houses, and using the land for different reasons. Trees filter the air that we breathe in. Now, since the number of trees has been reduced to a larger extent, so the filtering process does not take place much often. Also, for the past few years, fossil fuels are burning at a higher pace which has increased the number of pollutants in the air.

As responsible citizens, we should avoid doing such things that increase air pollution. We should indulge in reforestation. Planting more trees would result in a decrease in air pollution. Also, after the installation of industries, the gases that are sent out by the factories should be refined which would help minimize the toxic gases in the atmosphere. We can also start using eco-friendly fuels like CNG, LPG, etc. In this way, the harmful toxic gases would be minimized in the atmosphere.
