Another species is driven to extinction by human activity at the Yangtze River in China.The Yangtze, Asia’s longest waterway and thought to be akin to the Amazon long ago in its biological richness, now has a dominant species: the 400 million (and counting) people busily plying its waters and industrializing its banks.
For some 20 million years, the baiji, also called the white-flag dolphin, frequented the Yangtze’s sandy shallows, using sonar to catch fish in the silty flow.
In the last few decades, the dolphin’s numbers plunged as rapidly as the Chinese economy surged. The Yangtze’s sandy shallows, which the baiji frequented, have largely been dredged for shipping.
The baiji sought fish that have been netted or driven from the river by pollution. And its sonar may have been disrupted by the propeller noise from boats above.
