Extinction: 'Time is running out' to save sharks and rays 拯救瀕危物種鯊魚和鰩魚 “時不我待”
科學(xué)家們表示，鯊魚和鰩魚正以 “驚人” 的速度從世界海洋中消失。一項(xiàng)新研究表明，半個多世紀(jì)以來，公海海域的鯊魚數(shù)量減少了71% ，導(dǎo)致這個現(xiàn)象的主要原因是過度捕撈。在所有被研究的物種中，有四分之三正面臨滅絕的威脅。
The study found a dramatic decline in sharks and rays found in the open oceans, including hammerheads, mako sharks, and the giant manta ray.
研究發(fā)現(xiàn)，在公海海域發(fā)現(xiàn)的鯊魚和鰩魚數(shù)量急劇下降，其中包括雙髻鯊、灰鯖鯊和雙吻前口蝠鲼。
Since 1970, shark and ray catches have tripled, pushing many species to the brink of extinction.
自1970年以來，鯊魚和鰩魚的捕捉量增加了兩倍，這將許多物種推向了滅絕的邊緣。
The scientists say overfishing of sharks and rays jeopardises the health of entire ocean ecosystems, as well as food security for some of the world's poorest countries.
科學(xué)家們說，過度捕撈鯊魚和鰩魚危害整個海洋生態(tài)系統(tǒng)的健康，同時危及世界上一些最貧窮國家的糧食安全。
They're calling on governments to set science-based fishing limits to secure a brighter future for these extraordinary animals.
科學(xué)家們呼吁政府制定有科學(xué)依據(jù)的捕撈上限，以確保這些神奇非凡的動物能有一個更光明美好的未來。
