Air pollution is a grave issue in India. It is considered even more serious than the malnutrition in the country! The WHO study reveals that at least 14 crore people in India breathe air which is at least 10 times over the safe limit set by the organisation. Out of the 20 most polluted cities in the world, 13 are in India. Air pollution is also the cause behind the death of around 20 lakh people each year in India.
The major cause of pollution in the urban areas is emission from industry and vehicles. In rural areas, biomass burning is the main source of pollution. The air quality is degrading day by day. The diseases caused due to severe pollution, such as stroke, heart diseases, and lung cancer, have reached an alarming level. Needless to say, pollution has a direct effect on our health, and needs to be tackled on a war footing.
