Finless Porpoise
The polluted Yangtze River in China supports millions of people in poverty who are dependent on the river for all their washing, drinking and nutritional needs.
Barely surviving is also the critically endangered Baiji River Dolphin and Finless Porpoise.
Over-fishing using unsustainable methods such as dynamite has degraded the river and reduced fish stocks to the detriment of both wildlife and the people who fish the river system.
