In case things were not bad enough already in China, there is a serious situation rapidly turning into the risk of a catastrophe with the Three Gorges Dam. In brief, its structural integrity appears to be compromised. Combined with very high rainfall in the catchment area of the Yangtze River, the Dam is buckling and the authorities are releasing as much water as is possible to take the pressure off. But it might not be enough. Should the dam fail, it would cause a catastrophe in China.
The first impact would be humanitarian. Millions of people live and work downstream of the dam. Casualties would be large in number. The second impact would be local economic wipe out. The third would be international economic consequences. The fourth impact would be political reprisal. This is not looking good.
