    Polar Bears Fight For Survival in a Vanishing Sea Ice Environment The wooly white polar bear, the highest on the food chain in the Arctic marine ecosystem, is, in most minds, one of the universal symbols of the Arctic. But they may be disappearing. Throughout their range, they are dependent on sea ice for nearly all aspects of their life history. Evidence indicates that global climate patterns are changing, that these changes are exacerbated in Arctic regions, and that one of the most prominent affects of these changes is an altered sea ice environment. Hence, polar bears, which may be the first large mammal to show obvious effects of climate change, are an ideal "indicator" of the status of the Arctic system. Additionally, polar bears provide an important source of food and fiber to aboriginal Arctic peoples. In recent years, the relatively shallow waters over the Alaskan continental shelf, which are important foraging habitat for polar bears, have become unavailable during the late summer and early autumn because the summer melt has reduced the availability of sea ice in these regions. Polar bears have been forced into areas, either on shore or beyond the continental shelf, where they cannot hunt for their preferred prey. Where's there's no ice, there's
