Three Gorges Dam

Three Gorges Dam gives a lot of advantages to economic and environment to China. This is what i read from the articles online. To think of it, it may help to gain the economic of China but it does not help to protect environment.Why i am saying this? Of course Three Gorges Dam solves the flood problem in China but on the other hand it creates environment problem such as water pollution and climate change. When the water start to fill for generate electricity, the water start to become toxic and it causes death for the sea life. We all know that, when building Three Gorges Dam, people has lose their homeland because the water level will fill their homeland. Three Gorges Dam seem to be solve the environment problems in China but it creates new problems as well..Therefore i think that the negative effect is more than positive effect to build Three Gorges Dam.
