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.

our North Pole just got danger我们的北极也面临着危机how to protect it?怎样去保护
No one can say I can没有人能说，我能So Mother Nature is an exquisite and complex life-system. It\\\\'s charm appears in the trees, stream, soil, insects, moss and fungus, all the things on the earth in different shapes, which are interdependent. When you get close to nature, please remember, each tree, stone and species of animals here has lived harmoniously for hundreds, thousands or even millions of years. When we pass away, they will continue to live. They are the real masters, while we are just the passer-by. However, the conduct we unconsciously do, such as picking, lumbering, tramping and abusing can probably destroy the balance of their life. Therefore, we must reduce our bad influence as much as possible. While you are enjoying the nature, do not forget please, the beauty of the lives also needs to be concerned with and to be protected.Each life on the earth has a long and touching evolutionary story. From the origin, the lives of the human being are equal to those of others; they both are the composing parts of Mother Nature. Nevertheless, for some inexplicable reasons, the human becomes the spirits of all creatures. Of course, it is the result of the evolution, but still we should be grateful to all our companions in nature for the opportunity they offer.In spite of this, humans cannot live without earth. They live on the earth, drink the sweet water.and enjoy the sunshine, the air, the sky, the fruit; the grains utilize the energy and so on. In a word, the human being cannot live without nature, and Mother Nature makes us grow stronger.I do not like the word Pet, but preferring the word Animal instead. I have been loving animal since I was just a little boy. When thinking of the Pet Fashion, I always feel much annoyed. For the animals will be given a shackle and lose their liberty if they become someone\\\\'s pets. Their natural attribution can be deprived, too.Up to now, relying on their scientific power, the human have opened up too much and over developed nature, in order to fill up their growing appetites of wealth. They destroy the balance of nature, however, they don\\\\'t realize, their own development and existence will be threatened. Therefore, our sights should be focused on nature and we should try to develop the concept of keeping human and nature in unity.We should lay emphasis on our education with consider cultural and natural emotion. To use the vivid example to wake up the conscience in people\\\\'s hearts.To love nature is to love our mankind. As the new generation who enter the new century, we should make efforts to love and respect nature, to treat it well and protect it. Only in this way can we have a beautiful nature to enjoy it!（后面的我就不翻译了，太多了哈）O(∩_∩)O谢谢
