Another effect of air pollution is acid rain. The phenomenon occurs when sulphur dioxide and nitrogen
oxides from the burning of fossil fuels such as petrol, diesel, and coal combine with water vapour in the
atmosphere and fall as rain, snow or fog. These gases can also be emitted from natural sources like
volcanoes. Acid rain causes extensive damage to water,forest and even human health. Many lakes and
streams have been contaminated and this has led to the disappearance of some species of fish in Europe,
USA . Because the contaminants are carried long distances, the sources of acid rain are difficult to pinpoint
and hence difficult to control.
