The Guardian:

China already counts more dams within its borders than any other country. It has paid a huge price for this development. Chinese dams have displaced an estimated 23 million people. Dam breaks in the country with the world's worst safety record have killed approximately 300,000 people. Scientific evidence suggests that one particular project, the Zipingpu Dam, may have triggered the devastating earthquake in Sichuan of 2008. Dams have also taken a huge toll on China's biodiversity, causing fisheries to suffer and driving charismatic species such as the Yangtze River Dolphin to extinction.

Can this be really true? That earthquake was huge (7.9) and killed 80,000 people. Human development caused the earth to move like that? Wow. If so, then humans have really arrived. In the way bacteria changed the composition of the atmosphere billions of years ago, we are able to change, impact, influence the lithosphere today.
