What is the fate of Tibet? To explore that question, FRONTLINE asked Orville Schell, an author and longtime observer of China, to make the journey to the Roof of the World. Forty years of Chinese occupation have left tens of thousands of Tibetans dead and six thousand Tibetan monasteries and temples destroyed. Today, the Dalai Lama is in exile, Lhasa, the capital, is predominantly Chinese, and one of Tibet’s most sacred lakes is being developed for Chinese hydroelectric power. Schell vividly chronicles the history and culture of Tibet, explores the Chinese view of Tibet, and looks at why the survival of Tibet’s people and culture has become an international issue.
