The Yangtze

The Yangtze River runs almost 4,000 miles through China, making it the longest river in the country and the third longest river in the world. Considered a tremendous source of hydroelectric power, the river also contains the world’s most “notorious” dam. Construction began in 1995 on the Three Gorges Dam, which has displaces more than 1.2 million people and flooded hundreds of mines, factories and waste dumps. This has created a mass of pollution and waste flooding down the river, causing a chain of landslides threatening China’s largest fishery. China officially acknowledged the problems in 2011.
