Our Planet's Pollution

Pollution kills more people each year than wars, disasters and hunger, also causing huge economic damage, a study says. 

Almost half the total deaths occur in just two countries.

One in every six of the 9 million premature deaths worldwide in 2015 could be attributed to diseases caused by toxins in air or water, the study says. It says air pollution was the main cause of deaths, responsible for 6.5 million of the fatalities, followed by water pollution, which killed 1.8 million.

The estimate of 9 million premature deaths, considered conservative by the authors, is one and a half times higher than the number of people killed by smoking, and three times the death toll from AIDS, turberculosis and malaria combined. It is also 15 times the number of people killed in war or other forms of violence.

Ninety-two percent of pollution-related deaths occurred in low- or middle-income developing countries, with India topping the list at 2.5 million, followed by China at 1.8 million.

The Lancet editors Pamela Das and Richard Horton said the report came at a "worrisome time, when the US government's Environmental Protection Agency, headed by Scott Pruitt, is undermining established environmental regulations." Pruitt announced this month that the US, a major producer of air pollution and greenhouse gases, would be pulling out of former President Barack Obama's Clean Power Plan. The plan, which aimed to cut carbon dioxide emissions from electricity production, was expected by the EPA to also reduce smog and soot in the air by 25 percent and thus avoid thousands of premature deaths through asthma and other lung conditions.
