2.有关保护北极熊的英语作文100字

最近拍摄到的照片显示，由于全球变暖导致猎食地消失，北极熊开始捕食同类。北极熊通常在浮冰上抓捕海豹作为食物。浮冰融化，在海上猎食也越来越困难，北极熊的捕猎场所也不得不转移到陆地上。有更多的北极熊淹死在海里，因为它们被迫游向更远的海域去寻找食物。这些照片进一步证实了越来越多处于绝境之中的北极熊，开始捕杀自己的同伴。科学家们称本年度内已经发生八起这样的事件。美国地质调查局和世界自然保护联盟近日分析指出，由于全球变暖，极地浮冰融化，世界上仅存的20000到25000只北极熊还将减少三分之二。失去浮冰栖息地，北极熊将无法长期生存下去。包括原油和天然气钻探、海运及有毒物质污染，与气候剧变和浮冰融化相比都不值一提。

Polar Bears and Conservation Page 1 of 3 Click image to enlarge. Polar Bear Status Report Polar bears are a potentially threatened (not endangered) species living in the circumpolar north. They are animals which know no boundaries. They pad across the ice from Russia to Alaska, from Canada to Greenland and onto Norway's Svalbard archipelago. No adequate census exists on which to base a worldwide population estimate, but biologists use a working figure of perhaps 22,000 to 25,000 bears with about sixty percent of those living in Canada. In most sections of the Arctic where estimates are available, polar bear populations are thought to be stable at present. Counts have been decreasing in Baffin Bay and the Davis Strait, where about 3,600 bears are thought to live, but are increasing in the Beaufort Sea, where there are around 3,000 bears. In the 1960s and 1970s, polar bears were under such severe survival pressure that a landmark international accord was reached, despite the tensions and suspicions of the Cold War. The International Agreement on the Conservation of Polar Bears was signed in Oslo, November 15, 1973 by the five nations with polar bear populations (Canada, Denmark which governed Greenland at that time, Norway, the U.S., and the former U.S.S.R.). The polar bear nations agreed to prohibit random, unregulated sport hunting of polar bears and to outlaw hunting the bears from aircraft and icebreakers as had been common practice. The agreement also obliges each nation to protect polar bear denning areas and migration patterns and to conduct research relating to the conservation and management of polar bears. Finally, the nations must share their polar bear research findings with each other. Member scientists of the Polar Bear Specialist Group meet every three to four years under the auspices of the IUCN World Conservation Union to coordinate their research on polar bears throughout the Arctic. With the agreement in force, polar bear populations slowly recovered. The Oslo agreement is one of the first and most successful international conservation measures enacted in the 21st century.
