When completed in 2009, the Three Gorges Dam will be the largest hydroelectric dam in the world. Stretching a mile across the Yangtze and rising six hundred feet, it will be visible from the moon!
It's purpose is to bring much needed power to inland China and to control the periodic desructive flooding of the Yangtze, but it will also displace more than a million people, submerge ancient temples and burial grounds, endanger or wipe out rare animnals like the Yangtze River dolphin, and cover some of the world's most magnificent scenery.
And Out With The Old
The city of Fengu will be covered by the rising waters and, like the other doomed cities, is being torn down so as not to be a menance to navigation. However, the Ghost City part atop Mt. Minshan (now reached via a ski lift) will survive at the new water level.
