S1·E6 Tides of Change

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.
