摘要
一项研究称,气候变化正在饿死北极熊并导致它们灭绝。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。有科学家在《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。
Climate change is starving polar bears into extinction,according to research 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.
