Two out of every five species on th

Two out of every five species on the planet that have been estimated by scientists face extinction. This figure comes from the latest World Conservation Union Red List of Endangered Species, published this week.

In all, 16,119 animal and plant species are in danger of extinction. “From the poles(地球的两个极点) to the desert, species loss is increasing, not slowing down”, says IUCN director-general Achim Steiner. The main cause, as ever, is people, both directly and indirectly. While hunting and habitat(栖息地) loss continue to have a serious effect on species numbers, global warming is another threat.

In the polar regions (极地)，the summer sea ice that polar bears depend on is rapidly disappearing, and the latest estimates suggest that the ice will be reduced at least by fifty percent in area over the next century. Although polar bears are strong swimmers, yet large numbers of them will starve or drown as global warmingmelts the Arctic’s ice sheets. The world’s deserts may be expanding, but the animals that live in and around them are not faring well. It’s particularly difficult for the endangered species of the extreme habitat to recover their numbers. Meanwhile, our increasing demand for fish and water is placing the species in rivers and oceans in great danger. As shallow-water fish stocks get reduced, fishermen’s dropping nets and lines into deeper waters are taking their toll on species there.

“This trend can’t be stopped. Environmentalists alone can not save the world’s species in danger”, says Steiner, “but conservation (保护) can work. It must become the responsibility of everyone to act”.

科学家估计，在这个星球上的每五个物种中，有两个灭绝。这一数字来自于最新的世界自然保护联盟濒危物种名单，本周公布。在所有，16119种动物和植物物种有灭绝的危险。“从极点（地球的两个极点）到沙漠，物种损失增加，不会放慢，世界自然保护联盟总干事阿希姆Steiner说”。主要原因，如以往一样，是人，无论是直接或间接。而狩猎和栖息地（栖息地）损失继续在物种数量的严重影响，全球变暖是一个威胁。在极地地区（极地），夏季海冰，北极熊依靠迅速消失，最新的估计表明，冰就会减少了至少百分之五十的面积在下个世纪。虽然北极熊是强壮的游泳者，但大量的人会饿死或淹死在全球warmingmelts 北极的冰盖。世界上的沙漠可能会扩大，但动物生活在他们不好。这是特别困难的濒危物种的极端栖息地，以恢复他们的数字。同时，我们对鱼和水的需求越来越大，把该物种在河流和海洋中处于巨大的危险之中。由于浅水鱼类的库存减少，渔民的下降网和线进入更深的水域，他们的收费在那里的物种。“这一趋势不能停止。环保主义者不能单独在危险”，拯救世界的物种，”斯坦纳说，“但保护（保护）工作。它必须成为每个人的责任。
