根據(jù) IUCN（世界自然保護(hù)聯(lián)盟）的一份最新報(bào)告，一度瀕臨滅絕的幾種金槍魚的數(shù)量開始回升。在法國馬賽召開的  IUCN  世界自然保護(hù)大會(huì)上，該組織更新了它們的 “瀕危物種紅色名錄”。

A decade ago, all seven types of tuna were deemed at serious risk of extinction. Thanks to strict fishing quotas, four species are now starting to bounce back in some parts of the oceans, including yellowfin, bluefin and albacore.

十年前，金槍魚的所有七個(gè)品種都被認(rèn)為嚴(yán)重瀕臨滅絕。有賴于限制捕魚的配額制度，其中四個(gè)品種的數(shù)量在部分海洋區(qū)域開始出現(xiàn)回升，包括黃鰭金槍魚、藍(lán)鰭金槍魚和長鰭金槍魚。

The Global Director of the IUCN, Dr Jane Smart, says it's a message that conservation can work. But other marine creatures such as sharks are moving ever closer to extinction. 37% of sharks and rays are now threatened from overfishing, climate change and pollution.

IUCN（世界自然保護(hù)聯(lián)盟）的全球主管簡·斯馬特博士指出，這表明保護(hù)工作可以起作用。但與此同時(shí)，如鯊魚等其它一些海洋生物則正進(jìn)一步走向滅絕。如今37% 的鯊魚和鰩受到過度捕撈、氣候變化和污染的威脅。

And on land the world's largest lizard, the Komodo dragon, is in danger of extinction – with rising sea levels expected to shrink its habitat on a handful of Indonesian islands.

在陸地上，世界上體型最大的蜥蜴——科莫多巨蜥正面臨滅絕的危險(xiǎn)，海平面的上升預(yù)計(jì)將縮小它們在印度尼西亞為數(shù)不多的島嶼上的棲息地范圍。

3. What has helped to protect some species of tuna?
Strict fishing quotas have allowed some tuna species to bounce back.
