Overview: The Tibetan plateau covers a quarter of China – an area the size of Western Europe. This vast, windswept wilderness is one of the world's most remote places, defined by the glacier-strewn Himalayas. It's also home to some incredible wildlife such as the rare chiru, brown bears, wild yaks and the highest-living predators on Earth. There are more large creatures here than anywhere else in China. Defined by over a thousand years of Buddhism, Tibet has a unique culture that has nurtured remarkable beliefs. The programme discovers why this landscape and ancient culture is the life support system for much of the planet.
