Answer:
Air pollution in India is a serious health issue.[1] Of the 30 most polluted cities in the world, 21 were in India in 2019.[2][3] As per a study based on 2016 data, at least 140 million people in India breathe air that is 10 times or more over the WHO safe limit[4] and 13 of the world's 20 cities with the highest annual levels of air pollution are in India.[5] 51% of the pollution is caused by industrial pollution, 27 % by vehicles, 17% by crop burning and 5% by other sources.[6] Air pollution contributes to the premature deaths of 2 million Indians every year. Emissions come from vehicles and industry, whereas in rural areas, much of the pollution stems from biomass burning for cooking and keeping warm. In autumn and spring months, large scale crop residue burning in agriculture fields – a cheaper alternative to mechanical tilling – is a major source of smoke, smog and particulate pollution.[7][8][9] India has a low per capita emissions of greenhouse gases but the country as a whole is the third largest greenhouse gas producer after China and the United States.[10] A 2013 study on non-smokers has found that Indians have 30% weaker lung function than Europeans.[11]
