Junior high school geography composition: "Advantages and disadvantages of the Three Gorges Project" I want disadvantages
At the beginning of the construction of the Three Gorges Project, there were many problems such as ecology and cultural relics protection.

Baiji dolphin is an endangered mammal endemic to China. One of the disadvantages brought by the navigation capacity of the Three Gorges Project of tens of millions of tons is that the incidents of baiji being killed by propellers have increased, and the Chinese sturgeon agreed to cherish baiji has also become a victim. When the Three Gorges Project stores water every year, the natural water in the downstream will decrease, which may interfere with the habitat and spawning of Chinese sturgeon. Terrestrial organisms other than aquatic organisms, such as Chuanminshen, are damaged by being in flooded areas or building other facilities. ...

China is an ancient civilization, the Three Gorges area is rich in local characteristics, and the cultural relics are immeasurable. However, due to the large submerged area of the Three Gorges Project, there are many underground cultural relics and sites. Although there are some protection plans, some cultural relics have fallen below the submerged line, and there are few opportunities for excavation.

Looking at the pros and cons, I personally think that the advantages of the Three Gorges Project outweigh the disadvantages. Because many measures have been taken, its disadvantages have been scaled up, which is still less than its benefits-the safety of tens of millions of people. But when we look at its advantages, we should also see its disadvantages.
