The article discusses the fate of polar bears as a result of climate change and habitat loss. An example is given of unusual polar bear behavior in the Arctic regions of both Canada and Norway in which hungry polar bears searching for food became aggressive towards humans. Topics include how the loss of ice coverage in the Arctic regions has impacted the bears' feeding schedule, the economic aspects of polar bear tourism in Churchill, Manitoba, Canada, and a proposal by the Canadian government to place the polar bear on Canada's endangered species list. A brief overview of polar bear ecology is also presented.
