Air pollution, which kills an estimated 7 million people every year, is the biggest environmental health risk of our time.
Airborne pollutants are responsible for about one third of deaths from stroke, chronic respiratory disease, and lung cancer, as well as one quarter of deaths from heart attack. Air pollution is also fundamentally altering our climate, with profound impacts on the health of the planet.
Air pollution comes from many sources – from cookstoves and kerosene lamps to coal-fired power plants, vehicle emissions, industrial furnaces, wildfires, and sand and dust storms.
