A mini-doc I shot and co-directed with Ellen Xu on the efforts to save the Yangtze Finless Porpoise, a critically endangered species of dolphin that lives in China's Yangtze river. Overfishing, industrial pollution, river traffic and rampant sand dredging along Asia's second longest river has brought the number believed alive in the wild to just 1,000. Our trip with presenter Di To took us to Wuhan city, the heavily polluted Dongting Lake and Tianezhou, an oxbow lake once connected to the Yangtze that has become a safe haven for the porpoise. We focus on the efforts of inspiring individuals like senior researcher Wang Ding to stop the porpoise going the same way as its cousin the Baiji dolphin, which once swam the same waters but was declared functionally extinct in 2006. It's not just a story about one species. This beautiful creature is an 'indicator species' for the Yangtze, so its decline should send a sharp warning about the threat to river's entire ecosystem.
