2、The proposal was triggered by rising temperatures in the Arctic that are reducing the sea ice polar bears need for hunting

这项提议的出台源于北极地区气候暖化。气温上升导致北极熊捕食的海冰融化。

5、Warmer temperatures have caused the ice cap to melt, shrinking the bears' hunting grounds and making it increasingly difficult for them to find food

气温上升导致冰冠融化,缩小了熊的捕食范围,以至于北极熊觅食越来越困难。

6、Identifying polar bears as threatened under the Endangered Species Act could force US industries to reduce their carbon dioxide output to protect the Arctic predators

根据《濒危物种法》,确定濒危北极熊的名单后可以迫使美国工业降低二氧化碳的排放量以保护熊的生命安全。

7、The United States is the world's biggest emitter of greenhouse gases, the byproduct of fossil fuels blamed for trapping heat from the Sun and altering Earth's delicate climate system

美国是世界上温室气体的最大制造者。温室气体吸收来自太阳的热量,改变地球脆弱的气候系统。

8、The polar bear (Ursus maritimus) is well-adapted to its habitat: thick blubber and fur insulate it against the cold and its translucent fur (which appears white or cream-coloured) camouflages it from its prey

北极熊能很好地适应环境——厚厚的脂肪和皮毛隔绝了它们被外界寒冷气候的侵袭,透明的皮毛(通常呈现出白色或乳白色)便于它们伪装不被敌人发现。

10、But the Polar Bear Specialist Group of the World Conservation Union, based in Gland, Switzerland, has estimated that the polar bear population in the Arctic has dwindled to 20,000 to 25,000.

然而,位于瑞士格兰特的世界自然保护联盟北极熊专组预测说,生活在北极圈的北极熊数量已经下降至2万至2.5万只。
