The Yangtze River, or Chang Jiang, is the longest river in Asia and the third-longest in the world. It flows for 6,300 kilometers from the glaciers of the Qinghai-Tibet Plateau eastward into the East China Sea at Shanghai. The river basin is home to one-third of China's population and is crucial to the country's economy, history, and culture. It is the site of the Three Gorges Dam, the world's largest power station by installed capacity. The Yangtze is also a biodiversity hotspot, home to several endemic and endangered species, including the Chinese alligator, the narrow-ridged finless porpoise, and the now-extinct Baiji dolphin. However, industrialization and pollution have severely impacted the river's ecosystem, leading to massive conservation efforts by the Chinese government to restore its health and protect the species that remain.
