BEIJING - A rare, nearly blind white dolphin that survived for millions of years is effectively extinct, an international expedition declared Wednesday after ending a fruitless six-week search of its Yangtze River habitat.
The baiji would be the first large aquatic mammal driven to extinction since hunting and overfishing killed off the Caribbean monk seal in the 1950s.
For the baiji, the culprit was a degraded habitat — busy ship traffic, which confounds the sonar the dolphin uses to find food, and overfishing and pollution in the Yangtze waters of eastern China, the expedition said.
"The loss of a large animal like a river dolphin is often a harbinger for what's going on in the larger system as whole. It's not only the loss of a beautiful animal but an indication that the way its habitat is being managed, the way we're interacting with the natural environment of the river is deeply flawed ... if a species like this can't survive."
