根据 IUCN(世界自然保护联盟)的一份最新报告,一度濒临灭绝的几种金枪鱼的数量开始回升。在法国马赛召开的  IUCN  世界自然保护大会上,该组织更新了它们的 “濒危物种红色名录”。

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,金枪鱼的所有七个品种都被认为严重濒临灭绝。有赖于限制捕鱼的配额制度,其中四个品种的数量在部分海洋区域开始出现回升,包括黄鳍金枪鱼、蓝鳍金枪鱼和长鳍金枪鱼。

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(世界自然保护联盟)的全球主管简·斯马特博士指出,这表明保护工作可以起作用。但与此同时,如鲨鱼等其它一些海洋生物则正进一步走向灭绝。如今37% 的鲨鱼和鳐受到过度捕捞、气候变化和污染的威胁。

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.

在陆地上,世界上体型最大的蜥蜴——科莫多巨蜥正面临灭绝的危险,海平面的上升预计将缩小它们在印度尼西亚为数不多的岛屿上的栖息地范围。
