Air pollution is the contamination of air with the mingling of unwanted, harmful pollutants things like carbon dioxide, carbon monoxide, nitrogen oxides, sulphur oxides, mineral ash or fly ash in air many a times leading to global warming. Some of these pollutants mix with water vapour present in air to form droplets of sulphuric acid and nitric acid which fall on the earth in form of a rain called acid rain.
