Question

about pollution in 2021? (200 words max)

Answer 1

Answer:

Twenty-one of the world’s 30 cities with the worst levels of air pollution are in India, according to data compiled in IQAir AirVisual’s 2019 World Air Quality Report; six Indian cities are in the top ten.[1] Indeed, air pollution is pervasive in many parts of India, causing massive public health and environmental crises. The economic cost of fossil fuel air pollution alone is estimated at INR 10,700 billion, or 5.4 percent of the country’s annual GDP. An estimated one million deaths each year, and 980,000 pre-term births, are attributed to air pollution from fossil fuel in India.[2]

Among all the cities in India, some of the worst levels of air pollution are seen in its capital territory, Delhi. The impacts are devastating, including in the degree of particulate matter concentrations in the air (environmental), reduction in life expectancy (health), and high costs that the state is incurring to resolve the crisis (economic). The main sources of air pollution in Delhi include vehicle exhaust, heavy industry such as power generation, small-scale industries like brick kilns, suspended dust on the roads due to vehicle movement and construction activities, open waste burning, combustion of fuels for cooking, lighting, and heating, and in-situ power generation via diesel generator sets.[3] Compounding the problem are seasonal emissions from dust storms, forest fires, and open field fires during harvest season. Extreme air pollution from these sources affects millions of people in densely populated regions who are exposed to thick, toxic smog for long periods of time.[4]
