Polar Bears in Jeopardy

Global warming is melting the polar ice caps, robbing the bears of the ice floes they need to hunt prey. Forced to fast for longer periods, polar bears will become too thin to reproduce and many scientists predict they could become extinct by the end of this century. At the same time, their natural habitat is under increasing assault from expanded development
