Air pollution in India is estimated to kill 1.5 million people every year. It is the fifth largest killer in India, after heart diseases, diarrhoes, road injuries and self-harm. India tops world in bad air quality: According to WHO global air pollution database, India has14 out of 15 most polluted cities worldwide. The air quality in Delhi, the capital of India, according to a WHO survey of 1600 world cities, is the worst of any major city in the world.
Air Pollution is no longer a problem with large cities. Smaller cities have also been facing this problem- mostly in North India. But Eastern India has also started facing this problem.
For example, Cuttack, the millennium city flanked by two big rivers Mahanadi and Kathajodi- is one of the six cities in Odisha who are among the 102 cities of the country that have failed to maintain the national ambient air quality standards fixed by the Central Pollution Control Board.
