Pollution kills nine million each year – the equivalent to one in six deaths, damning report finds (so, how many people does it kill in your country?)

Air pollution, water contamination and exposure to man-made chemicals claimed nine millions live last year, a major study concludes.

Researchers discovered at least one in six deaths across the world were caused by the three forms of deadly pollution.

The biggest killer was air pollution, which accounted for 6.5 million deaths on its own, a report published in the prestigious medical journal The Lancet found.

Scientists at the Icahn School of Medicine in New York City put the majority of the deaths down to heart disease, stroke, lung cancer and chronic obstructive pulmonary disorder (COPD).
