科学家们表示,鲨鱼和鳐鱼正以 “惊人” 的速度从世界海洋中消失。一项新研究表明,半个多世纪以来,公海海域的鲨鱼数量减少了71% ,导致这个现象的主要原因是过度捕捞。在所有被研究的物种中,有四分之三正面临灭绝的威胁。
The study found a dramatic decline in sharks and rays found in the open oceans, including hammerheads, mako sharks, and the giant manta ray.

Since 1970, shark and ray catches have tripled, pushing many species to the
brink1 of
extinction2.
自1970年以来,鲨鱼和鳐鱼的捕捉量增加了两倍,这将许多物种推向了灭绝的边缘。
The scientists say overfishing of sharks and rays jeopardises the health of entire ocean
ecosystems3, as well as food security for some of the world's poorest countries.
科学家们说,过度捕捞鲨鱼和鳐鱼危害整个海洋生态系统的健康,同时危及世界上一些最贫穷国家的粮食安全。
They're calling on governments to set science-based fishing limits to secure a brighter future for these extraordinary animals.
