50 years ago there is no more air pollution because there are not more industries and factories which makes more pollution and their are not more availability of motorcycles and vehicles that's why the air pollution is under control 50 years ago.
today there is so great air pollution in Delhi it is so dangerous air pollution occurs because of release of carbon dioxide and harmful gases.
and also because of using great number of vehicles which also release carbon dioxide and harmful gases we are cutting plants and trees for our purpose that's why air pollution occurs
we get oxygen from plants by the process of photosynthesis that's why the plants and trees are useful for us and we are cutting them that's why it is so dangerous for us we are cutting our own lungs.
50 years ago there were many trees that's why there is a fresh air that's why air pollution does not occur a great.
that's why we have to plant trees and save trees.
