China's emperors built the Great Wall to keep their kingdom safe from the hostile barbarians to the north. This is a land of warrior tribes, bizarre wildlife and extreme weather, but also of vast and breathtaking evergreen forests, grassy plains and sweeping desert dunes, rich with history. The legendary Silk Road drew traders and their camels across the deserts in search of fabulous wealth, and fierce Mongolian horsemen conquered the known world. Today, nomadic tribesmen still race horses and hunt with golden eagles, while tiny hamsters and Asia's last wild horses struggle to survive in the world's most northerly desert.

Hidden beneath billowing clouds, in China's remote south west, are perhaps the richest natural treasures in all China. Immense rivers carve their way south below towering peaks. The wind-swept slopes are home to the highest-living primates in the world and hidden in the valleys below are jungles with a diversity of wildlife comparable to those around the Amazon.

From the eastern end of the Great Wall, China's coast spans 14,500km and more than 5,000 years of history. This is a place of huge contrasts: futuristic modern cities jostling with traditional seaweed-thatched villages, ancient tea terraces and wild wetlands where rare animals still survive. Here Chinese white dolphins, red-crowned cranes, deadly vipers, giant sturgeon and sabre-wielding monkeys struggle to eke out a living faced by competition from 700 million people, widespread pollution and over-fishing. How China is managing such conflicting pressures has lessons for us all.

China's heartland with its Han people is the centre of a 5,000-year-old civilization. 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.
