The cast iron of the ices of the Arctic forces the world population of polar bears towards a territory quickly artificial, which threatens the species of extinction. The scientists declared yesterday that this premature annual cast iron of the ice caused by the change of climate, cut court at the season of hunting necessary to the bears, those needing the floating ice-barrier to go to seek their preys.
The disappearance of the ice during the summer months forces the population of famished polar bears to traverse long ways on their territory in search of food, giving a false impression which manpower increases and overflows on the human grounds.
Search on the bears in 5 areas of the Arctic discovered that the ice is withdrawn more and more early over the years, when one compares the images satellite since 1979 until 2004.
The study discovered that the season of hunting of spring was reduced of at least 3 weeks on certain areas, reducing the level of grease by at least 80 kg per animal.
As the females are thinner, they weaker and are exposed to the diseases. Their capacity to be reproduced and the chances of survival of their small decline significantly.
