长江白鳍豚昨日已宣布绝迹 & 三峡工程掠影

新华社讯昨天，为期38天的寻找白鳍豚之旅到达终点站武汉。科考队遗憾地宣布，来回3336千米的考察未发现一头白鳍豚。覆盖白鳍豚历史分布江段的长江科考未寻找到最后的白鳍豚，科学家们称这个结果证明白鳍豚种群状况极度濒危，可能成为世界上第一个被人类消灭的鲸类动物。
白鳍豚处于长江水生生物食物链的顶端，在长江水域中没有任何天敌，因此其灭绝不可能是自然原因造成，它所面临的所有威胁都来自人类。

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."

2个月前在今日雨果的博客里，我读了他的童话《小白豚找爷爷奶奶 》，以及《白豚，不该消失的长江女神 》。感到了震惊，因为我的家就在长江的边上。而今早我看到了这个消息。用悲哀也许难以形容。也许只有我们可以生存在钢筋和水泥的世界里. 去年在三峡的大坝的顶上，曾感慨人类的雄伟！但我们的代价呢！
