Severe Air Pollution Might Have Killed Millions Worldwide

Air pollution has become a major health issue worldwide, and now, new research suggests it's linked to 5.5 million premature deaths.

According to data from the Global Burden of Disease project, air pollution — both in the home and outside — ranked as the fourth highest contributor to death worldwide.

China and India topped the list of countries with the majority of deaths, with 1.6 million and 1.4 million respectively.

"One of the reasons we're focused particularly on China and India is that the sources that contribute to air pollution are also major sources contributing to climate change," said a professor at the University of British Columbia.

Those findings come from 2013, the most recent year that data is available. But Beijing's smog levels have made headlines for years. As pollution levels rose higher at the end of 2015, the government warned people to stay inside.

And this past November in India, New Delhi issued a severe air pollution warning of its own.

For both countries, estimates say pollution levels are expected to continue rising through 2030 despite commitments to curb the problem.
