What problem has china tried to solve by building hydropower dams, such as the three gorges dam? a. scarcity of water b. lack of arable land c. production of greenhouse gases d. damage from earthquakes and tsunamis

C. production of greenhouse gases

Explanation:

The Chinese government opted to build megausin "Three Gorges Dam" in the early 1990s (in operation since 2006) on the grounds that it would generate green energy, reduce carbon dioxide emissions, and help control the floods of the Yangtze River.

According to official figures, the dam is capable of reducing carbon dioxide emissions in the country by 100 million tons per year, which helps prevent global warming.

On the other hand, project critics have long warned of the side effects of the work.

In addition to causing ecological damage now recognized by the authorities, the plant also contributes to the destruction of the historical heritage of the cities that have been flooded, as well as causing misery for populations displaced by the project.

The impact of the dam on wildlife in the region is another sensitive issue raised by critics.
