Study: North China lives cut 5 years by coal burning
People in northern China may be dying five years sooner than expected because of diseases caused by air pollution, an unintended result of a decades-old policy providing free coal for heat, a study found. Coal burning leading to heart disease, stroke, lung cancer and respiratory illnesses may cause the 500 million Chinese living north of the Huai River — a rough line dividing the country's north and south — to lose an aggregate 2.5 billion years of life expectancy, according to the research published in the Proceedings of the National Academy of Sciences.
