Environment of Qinghai-Tibet Plateau under threat

From Xinhua:

The Qinghai-Tibet Plateau in southwest China, long known as the “roof of the world,” faces serious ecological threat that may ruin the already fragile environment which has fostered numerous rare animals, plants and medicine herbs, Chinese scientists say.

A group of scientists with the Qinghai-Tibet Plateau Study Institute of the Chinese Academy of Scientists who have carried out a decades-long study of the geography of the plateau warned that its environment will continue to deteriorate because of climate changes, overgrazing and increasing human activities.
