Air pollution is now the single biggest global health hazard, according to a new report from the World Health Organization. Seven million people died worldwide from dirty air in 2012. About half of those deaths came from indoor pollution - from cooking on coal stoves - and most of the deaths from outdoor pollution were in Asia. But air isn’t stagnant... We have some of that dirty air from China here. Plus our own homegrown smog.
