Polar Bear King of the ice cover, which coats the Arctic pole of the planet, the disappearance of ice, which used it to catch prey causes him food deprivation in the summer .

Scientists believe polar bear can deter this threat and overcome the scarcity of food through the entry in diapause to save energy.
Scientific studies have shown that it does not happen, as researchers have continued to monitor the change in the heat of the bodies of animals and their activities and the movement's 30 polar bear and concluded that the bears can not reduce capacity but little could last up and not to compensate for food deprivation.
The scientists planted Precision Equipment to measure the degree of polar bears heat each hour as they put collars around the necks of bears are connected to satellites to monitor their movements and rates of activity with help of those technical.

Also it threatens to melt the ice in the polar bear's life spring season and prevented him from hunting from what prevents fat storage and this affects the life of the polar bear.
There are other challenges facing the polar bear, including drilling for oil and gas operations and hunted by the indigenous people and the rest of the impact of weak Makornt factors as loss of ice cover.
