With the continuation of global warming and the melting ice caps, polar bears are in danger of extinction. Polar bears main food source being seals, polar bears need the ice to rest on in order to hunt the seals. Though polar bears main food source are seals scientist are beginning to believe that polar bear have other food source possibilities such as caribou and snow geese. Before scientist can conclude that these are sustainable food scientist must first conclude whether or not the calories gained from the land animals is more than the polar bears exhaust while hunting. And if the polar bears will develop the instinct to hunt inland for food.
The fate of the polar bears are important because they are a link in the food chain and with out polar bears our already fragile animal system can be even more damaged. We as humans are most responsible for the destruction of the polar bear's habitat and we are responsible for their inability to hunt properly. We as humans must realize the role we play in the ecosystem and adjust our way of life so not to end theirs.
