Air pollution is an insidious problem that doesn’t recognize borders and travels thousands of miles. In fact, Americans are producing less pollution but experiencing greater amounts of smog on the West Coast, the result of pollutants originating in Asian countries.1 In 1991, the U.S. and Canada entered into an agreement to address transboundary air pollution that led to a reduction in the production of acid rain.2
A collaboration of more than 40 researchers looking at data from 130 countries has called air pollution the “largest environmental cause of disease and premature death in the world today.”3 Nine million premature deaths were attributed to air pollution in 2015 — 16 percent of all deaths worldwide and three times more than AIDS, tuberculosis and malaria combined. Fine particulate matter is the most studied type of air pollution and refers to particles smaller than 2.5 micrometers in diameter.
