The Qinghai-Tibet Plateau is located in the southwest of China, with an area of around 2.3millions square kilometers and an average elevation of more than 4000 meters. It is known as the Roof of the World. The plateau has abundant natural resources, the beautiful scenery and a variety of rare wild animals. The Qinghai-Tibet Plateau is covered by vast areas of glaciers because of its extremely low temperatures. It is the birthplace of many famous rivers in Asia and the main source of water supply in China and southeast Asia. It is vital to the global ecosystem. The glaciers of Qinghai-Tibet Plateau are melting at an accelerating rate due to the effect of climate change. China has been making great efforts to protect the plateau's ecosystem. The grass coverage rate has been increasing and many endangered species have been better protected.
