Explanation:

A recent study estimated that upwards of nine million deaths were directly caused by pollution in 2015. Bangladesh had the highest portion of fatalities caused by pollution, with roughly 26%. This is followed closely by India with 24.5% and Pakistan with 21.9%. Although China and the US are the largest carbon dioxide emitters in the world, their rates were rather low, with China experiencing 117 deaths per 100,000 and the US experiencing 21. On the other hand, in 2016, 1.5766 million people died in China from air pollution, and 105,100 people died in the US.
