What are the pros and cons of building the Three Gorges Dam?

If you want to obtain huge benefits, you must pay a huge price. The damage caused by the dam is also quite serious: more than 1 million people must be relocated, fertile riverside land will be submerged; rare and endangered species may face the threat of extinction; some important historical places and monuments will be submerged, some of which It can even be traced back to more than 2,000 years ago.

Other impacts include: irreversible changes to the hydrological characteristics of thousands of kilometers of rivers, damage to fisheries and aquaculture, complex changes to downstream floodplains, and the It will increase the possibility of some kind of flood, etc.

Because of immigration and large-scale relocation, the plants in the Ku area of ??the Three Gorges have suffered a devastating disaster. As for whether Fuling mustard will be called mustard in the future, no one knows, and due to soil erosion, the flowing river has become stagnant water , How can environmental protection in the reservoir area eliminate white pollution? Which area will the floodwaters be discharged to during the flood season?

In particular, the project will seriously affect the fish living in the middle reaches of the Yangtze River, and this water area is precisely It is the main habitat for thousands of species of rare fish unique to China, among which the Chinese sturgeon and white-tip dolphin, which only live in the middle and lower reaches of the Yangtze River, are even more concerning. The construction of Gezhouba Dam may have seriously affected the breeding of Chinese sturgeons, and the number of white-finned dolphins has also dropped to only a few hundred. In addition, another wild species worthy of attention is the endangered Siberian crane.

Yangtze River The main disadvantages of the Three Gorges Project in the middle and lower reaches are the threat of war, induced earthquakes, and damage to the environment and biosphere.

Their overwintering habitat will undoubtedly be affected by the dam.
