This land contains the Great Wall, the Temple of Heaven, and Beijing's Olympic Stadium and is home to some of China's most charismatic creatures such as the giant panda, golden snub-nosed monkey, and golden takin. China has undergone significant development in the past 50 years, bringing many environmental problems. The programme explores the deep, complex and often extraordinary relationship between the Chinese peoples, their environment and its creatures, and finds out what it means for the future of China.
