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 conct 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.

⑷ 用英文介紹北極熊
The polar bear (Ursus maritimus) is a bear native to the Arctic Ocean and its surrounding seas. The world's largest predator found on land, an alt male weighs around 400– kg (880–1,500 lb), while an alt female is about half that size. Although it is closely related to the brown bear, it has evolved to occupy a narrow ecological niche, with many body characteristics adapted for cold temperatures, for moving across snow, ice, and open water, and for hunting the seals which make up most of its diet. As it can hunt consistently only from sea ice, the polar bear spends much of the year on the frozen sea, although most polar bears are born on land.
The polar bear is classified as a vulnerable species. Of the 19 recognized polar bear subpopulations, 5 are declining, 5 are stable, 2 are increasing, and 7 have insufficient data. For decades, unrestricted hunting raised international concern for the future of the species; populations have rebounded after controls and quotas began to take effect. For thousands of years, the polar bear has been a key figure in the material, spiritual, and cultural life of Arctic indigenous peoples, and the hunting of polar bears remains important in their cultures.
The IUCN now lists global warming as the most significant threat to the polar bear, primarily because the melting of its sea ice habitat reces its ability to find sufficient food. Sea ice melting will also cause changes in their mating, and traveling patterns. The IUCN states, "If climatic trends continue polar bears may become extirpated from most of their range within 100 years." On May 14, 2008, the United States Department of the Interior listed the polar bear as a threatened species under the Endangered Species Act.

The polar bear is the largest animal in the bear family, body length of up to 2.5 meters, 1.6 meters high, weighing 500 kg. Polar bearsare not only good at swimming in cold water, but also good at quick jump on the ice, the maximum can reach a height of 1.8 metres. As the "king of the Arctic Circle", except for humans, bears almost no natural enemies。希望採納！來自
北極熊是熊科動物中最大的，體長可達2.5米，高1.6米，重500公斤。北極熊不僅善於在冰冷的海水中游泳，還擅長在冰面上快速跳躍，最高可以達到1.8米的高度。作為「北極圈之王」，除去人類，北極熊幾乎沒有天敵
⑹ 用英語介紹北極熊是瀕危動物〔200單詞〕
A polar bear carcass found on the Arctic island of Svalbard, the northernmost part of Norway, has shocked experts who say climate change may be to blame for the animal's death.
在挪威最北端北極圈Svalbard群島，人們發現了一隻北極熊的屍體，研究人員認為它的死因是氣候變化所造成的。
The starved polar bear in Norway was said to be in good health in April when the Norwegian Polar Institute examined and tagged it. However, the animal was reced to skin and bones by the time a group of explorers happened upon its body in July.
四月份挪威極地研究所在幫它檢查做標記時，這只北極熊的健康狀況還很不錯。但是，當一隊探險者7月偶然發現它時，早已瘦成了皮包骨。
"From his lying position in death the bear appears to simply have starved and died where he dropped," polar bear expert Dr. Ian Stirling, an adjunct professor at the University of Alberta, told The Guardian. "He had no external suggestion of any remaining fat, having been reced to little more than skin and bone."
「從它的卧姿來看，這只北極熊餓得倒了下來，最後死在了這里。」阿爾伯塔大學的兼職教授，同時也是北極熊專家的伊恩·斯特林博士告訴《衛報》記者，「外部跡象顯示它的身體已沒有任何脂肪，只剩下一具皮包骨。」
Stirling believes the bear starved to death as a result of a lack of sea ice, which the animals use as a platform for hunting seals. That may also explain why the 16-year-old male bear was found about 155 miles north of where it was seen in April.
斯特林博士堅信這只熊餓死是由於海冰的融化造成的，北極熊靠這些海冰來捕食海豹。這也解釋了為什麼這只16歲的雄性北極熊死在了離4月的所在地155英里的地方。
Arctic sea ice reached a record low in 2012, according a report released this week by the National Oceanic and Atmospheric Administration that pointed to continued signs of climate change.
2012年，北極的海冰達到了歷史最低，根據美國國家海洋和大氣管理局這周發布的報告顯示，氣候變化還將繼續。
The International Union for Conservation of Nature currently classifies polar bears as vulnerable on its Red List of Threatened Species

⑻ 給一段描述北極熊的英文
The polar bear is a bear native to the Arctic. Polar bears and Kodiak bears are the world's largest land carnivores, with most alt males weighing 300-600 kg ; alt females are about half the size of males. Its fur is hollow and translucent, but usually appears as white or cream colored, thus providing the animal with effective camouflage. Its skin is actually black in color. Its thick blubber and fur insulate it against the cold. The bear has a short tail and small ears that help rece heat loss, as well as a relatively small head and long, tapered body to streamline it for swimming.
A semi-aquatic marine mammal, the polar bear has adapted for life on a combination of land, sea, and ice, and is the apex predator within its range. It feeds mainly on seals, young walruses, and whales, although it will eat anything it can kill. It is the bear species most likely to prey on humans.
The polar bear is a vulnerable species at high risk of extinction. Scientists and climatologists believe that the projected decreases in the polar sea ice e to global warming will rece their population by two thirds by mid-century. Local long-term studies show that 7 out of 19 subpopulations are declining or already severely reced. In the USA, the Center for Biological Diversity petitioned to up-list the legal conservation status of polar bears to threatened species in 2005. This petition is still under review.
⑼ 英文的介紹北極熊英文
The polar bear (Ursus maritimus) is a bear native largely within the Arctic circle encompassing the Arctic Ocean, its surrounding seas and surrounding land masses. It is the world's largest carnivore species found on land. It is also the largest bear, together with the omnivore Kodiak bear which is approximately the same size.[3] An alt male weighs around 350– kg (770–1,500 lb),[4] while an alt female is about half that size. Although it is closely related to the brown bear, it has evolved to occupy a narrow ecological niche, with many body characteristics adapted for cold temperatures, for moving across snow, ice, and open water, and for hunting the seals which make up most of its diet.[5] Although most polar bears are born on land, it spends most of its time at sea, hence its name meaning "maritime bear", and can hunt consistently only from sea ice, spending much of the year on the frozen sea.
