Smog in China

Yahoo NewsJanuary 23, 2015

The skies of China's notoriously smog-filled cities saw a marginal improvement last year, according to figures released by Greenpeace Thursday, but pollution remained far above national and international standards.

China's cities are often hit by heavy pollution, blamed on coal-burning by power stations and industry, as well as vehicle use, and it has become a major source of discontent with the ruling Communist Party.

Retired senior officials have acknowledged that it may kill as many as half a million people a year. (AFP)
