With rising temperatures, the polar bears environment on which they live, sleep, hunt and breed (the ice), is melting. Their home is becoming smaller and smaller, year after year. Polar bears main diet consists of seals, which they hunt from the ice. With the decreasing ice platforms, it is more and more difficult for polar bears to hunt for their meals. Melting ice is confining the polar bears to land, which in turn leads to starvation. Drowning is also becoming more common, as the polar bears are forced to swim further out to sea to find food.
