The Atlantic has recently published a global map of air quality. Take a look at the interactive map to find out how the quality of the air you’re breathing compares with other countries and cities.The news isn’t good if you’re in China, India, Nepal, Pakistan, and Bangladesh.
The map overlays two sources of data on air pollution: for cities, the World Health Organization’s 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.
