Academy Award-winner F. Murray Abraham narrates Arctic Bears, a compelling cautionary tale of global warming ripped from today's headlines. As temperatures in the Arctic slowly rise and the ice recedes, food sources that the polar bear have come to rely on are becoming less plentiful. With the environment in flux, the polar bear faces a new challenge, a fierce rival pressing north from the tundra -- the grizzly! Ordinarily,their paths would never meet, but the line between their worlds is no longer clear. If the grizzly claims the Arctic, what will happen to the polar bear? This disc contains the bonus program, Showdown at Grizzly River, which follows one bold little bear's coming of age at Alaska's McNeil River Falls, a popular nursery spot for growing grizzly bears. Rating: TV-PG (on both episodes).
