Air Pollution Crisis: NYC Records Worst Air Quality in the World.

Air-quality readings like the ones expected across parts of New York State on Wednesday would not be seen as particular cause for alarm in some parts of the world. Cities across Asia, Africa and Latin America have been so polluted for so long that air-quality readings like the ones expected across parts of New York State on Wednesday would not be seen as particular cause for alarm. The World Health Organization found that 99 percent of the world’s population lived in places that did not meet its guidelines for healthy air quality. The effects of outdoor and household air pollution are associated with about 6.7 million annual deaths worldwide, mostly in low- and middle-income countries.
