Pros:
 * It produces 18 gigawatts of hydroelectric power with 26 generators and 32 turbines.
 * Reservoir lets 10,000 tons ocean freighters sail directly into the nation's interior for 6 months in 1 year.
 * It can block floods and give electricity. People claim that 1 million people lived in the last 100 years.
 * Dams can store rain water or water directly from the river itself. Just, in case of a drought, the dam will still have a relatively constant supply of water.
 * Producing Power.
 * Controls flooding & provides recreational activities such as boating fishing and swimming, if the lake is not being used for drinking water (Dam Society).
 * If needed, dams can be shut down instantly, where thermal plants take hours, and nuclear plants can take days! (Dam Society).
 * China has undertaken the greatest project since building the Great Wall of China and the Grand Canal.
 * It can generate electricity equal to about 40,000,000 tons of coal.
 * Hydroelectricity is better than coal burning because it doesn't cause more global warming.
 * Provides 18 new clear power-plant electricity.
 * If the next flood happens **//without//** the dam, the government officials will lose 30,000,000,000 yuan.

 * Hydroelectric power production require flooding of entire valleys and scenic areas.
 * Disrupts natural seasonal changes in he river, and ecosystems can be destroyed.
 * Ends flooding that help to clean out the silt in rivers, causing them to clog (Energy Laboratory).
 * The silt that usually flows down to the beaches and estuaries is block by the dam.
 * Dams can break in a massive flash flood.
 * More than 2 million people have to move if it is built.
