Dolphin feared extinct in polluted Yangtze

Overfishing and boat noise are killing aquatic mammals in Chinese river.

Human activity in China's Yangtze river is causing the region's dolphins to go extinct — and more species will follow if fishing is not regulated, conservationists have warned.

Scientists on an expedition in China claimed this week that the freshwater baiji (Lipotes vexillifer), also called the river dolphin, should be declared 'functionally extinct' in the river.
