近几年我们经常从资讯上看到饿得皮包骨头的北极熊,因为气候变暖、海冰消融,靠浮冰捕食海豹为生的北极熊长期找不到食物,甚至沦落到去垃圾堆里翻找东西吃。然而更可悲的是,如今科学家的新研究发现,北极熊很可能撑不过这个世纪了。 Climate change is starving polar bears into extinction, according to research published Monday that predicts the apex carnivores could all but disappear within the span of a human lifetime. In some regions they are already caught in a vicious downward spiral, with shrinking sea ice cutting short the time bears have for hunting seals, scientists reported in Nature Climate Change. 周一发布的一项研究称,气候变化正在饿死北极熊并迫使它们灭绝。该研究预测,北极熊这一食物链顶端的食肉动物可能会在百年内几近灭绝。科学家在《自然气候变化》上发表的报告称,在部分地区,由于海冰消融缩短了北极熊捕食海豹的时间,北极熊已经陷入数量螺旋式下降的恶性循环。 all but: 几乎,差一点 |
