Polar bears, is also called arctic bear in the arctic grows, it is the largest predator on land. In its existent space, it is the topmost food chain.

Last spring, even under the rain for several days, the entrance of the bush more than a small squirrel. Head on the tree On a nest, I do not know where it is not from the fall.

"I..." I just out of a word, I can not speak it out, because I really don't know what to. I paused for a moment, oh, the truth to her say, "I do not intend to, every day will be sleeping, watching tv." She said: "so many times not to slip away? Time is like gold, you can grasp, it will experience its valuable; let it go, it is like a runaway horse, will runfaster. I'm going to the university entrance exam, taking advantage of the summer to prepare high schoolcurriculum, so that the school would not be too nervous, summer vacation is not white. You should have a goodplan, make full use of the long summer vacation." She had to shoulder the burden, tossed braids, looked at thepiece of the old table, apologetically said: "I do not like this, to teach you. I'm sorry, time is early fall. I should go."

Polar bears straits:the tragedy is not only kill each other
Starving polar bears turn to cannibalism.
New pictures show that polar bears are beginning to cannibalise each other as global warming destroys its hunting grounds.
Polarbears usually subsist on seals,which they hunt from a platform of seaice.But the melting of sea ice as a result of rising globaltemperatures has made it more difficult for polar bears to hunt sealsat sea,confining the bears to land.
Drowning is also more common as bears are forced to swim further out to sea to find food.
Theimages add to the evidence that polar bears are increasingly huntingeach other for food in their desperation to survive.Scientists say theyare aware of eight cases so far this year.
Recentanalysis by the US Geological Survey and World Conservation Union foundthat two-thirds of the 20,000 to 25,000 polar bears in the world couldbe lost in the next 50 years as warming temperatures melt the ice.
Withoutthe sea ice habitat,the polar bear will not survive in the long term.There are other threats,such as oil and gas drilling,shipping andtoxins,but th ey pale in comparison to climate change and the loss ofthe sea ice
