World Today

A recent study shows more than 50,000 premature deaths could be saved in the U.S. if one year of microscopic air pollution – mainly from fossil fuel emissions – was eliminated.

The World Health Organization says millions of people globally are affected by air pollution. Campaigns to raise awareness of the people most affected are underway.
