Air pollution kills millions

 SEVEN million people died as a result of air pollution in 2012, the World Health Organisation estimates.
Its findings suggest a link between air pollution and heart disease, respiratory problems and cancer.
One in eight global deaths were linked with air pollution, making it “the world’s largest single environmental health risk”, the WHO said.
Nearly six million of the deaths had been in South East Asia and the WHO’s Western Pacific region, it found. – BBC
The WHO said about 3.3 million people had died as a result of indoor air pollution and 2.6 million deaths were related to outdoor air pollution, mainly in low- and middle-income countries in those regions. – BBC
