Answer 1

Answer:

Air Pollution :

The main sources of air pollution in India and elsewhere are mineral dust and gases, automobiles, thermal power plants and industries. Any contamination in the air may not only cause many diseases and loss of vision but can also disturb the whole atmospheric system. Air pollution can also cause acid rain which damages soil, vegetation and aquatic life of the region.

The heavy use of automobiles causes pollution and smog from automobile emissions. This has become a serious problem in almost all the countries—developed and developing.

The bad urban air bums the eyes, damages lung tissues and increases the levels of lead and other poisons in the human body and agricultural products. It is not known how many deaths occur nationally because of air pollution. Air pollution caused massive smog in London in 1952 killing some 4,000 people.

Water Pollution : All the Indian rivers, including the holy river Ganga, have become highly polluted today. Even, the Ganga Action Plan to control its water from pollution has not been proved successful. The impact of water pollution is widespread. It causes many severe water-borne diseases, such as diarrhea, trachoma, intestinal norms, hepatitis, jaundice, etc.

According to WHO, 21 per cent of all communi­cable diseases in India are water-borne diseases. Oil is the major pollutant of the sea water. Huge tankers routinely dump oil into the sea. This act of dumping poisons smothers or coats sea plants and animals and kills them.
