An incredibly rare dolphin is now functionally extinct in Laos, according to the World Wildlife Fund.
据世界野生动物基金会称，一种极为稀少的海豚在老挝功能性灭绝了。
The Irrawaddy dolphin's Laotian population shrunk from six down to just three individuals,too few to ensure the population will survive.
老挝短吻海豚的数量从六只缩减到三只，太少了以至于很难确定种群的生存。
Fishing nets,especially gill nets,are the main culprit behind this quick decline.
捕鱼网，特别是刺网，是数量下降的主要原因。
The nets are hard for the dolphins to see or find with echolocation. So they end up swimming into the nets and tangling themselves up, eventually drowning.
海豚很难看见或使用回声定位发现渔网。所以它们游向渔网并缠绕起来，最终溺亡。
The problem is called bycatch, and it doesn't just hurt the river dolphins. It threatens marine species all over the world.
问题叫做副捕获物，它不只是伤害河海豚，还威胁着世界各地的海洋物种。
Every year, more than 300,000 whales and dolphins die after getting caught in fishing gear.
每年，超过300,000头鲸鱼和海豚被渔具抓获后死亡。
There are still groups of the Irrawaddy dolphin in other parts of Southeast Asia. But in most of those groups, there are fewer than 100 dolphins left.
在东南亚的其它地方仍有成群的短吻海豚。但在大多数这些群体中，只剩下不到100只海豚。
