Linfen - The most polluted city on Earth

Northwest of Xian, the city which houses the Terracotta warriors, you will find a small city (4.3 million, which is small by Chinese standards) called Linfen. The Shanxi province is perhaps the energy capital of China. Like Niagara Falls for Ontario, Linfen produces much of North China's energy, typically using coal. The province has roughly 1/3 of all of the coal in China.

VBS recently made a documentary about this toxic city, and it's worth check it out. If you like it, you might also like their documentary about North Korea that I watched after visiting the DMZ.
