How Clean is the Air Youre Breathing? Take a look at this interactive map published by the Atlantic to find out how the quality of the air youre breathing stacks up against other countries and cities. A word of warning: the news isnt good if youre in China, India, Nepal, Pakistan, and Bangladesh. The map overlays two sources of data on air pollution: for cities, the World Health Organizations ambient (outdoor) air pollution in cities database 2014; for countries, ground-level exposures to fine particulate matter (PM2.5) are derived from satellite measures used in the 2014 Environmental Performance Index, a biennial global ranking produced by Yale and Columbia researchers that compares countries on high-priority environmental issues.
