I read an article on Polar Bears lately, and it didn't sound very hopeful. It was basically about a petition PETA has started to prohibit polar bears being kept in zoos (too small enclosures, and they suffer in the heat of the summer), but it also mentioned the melting of the ice caps. The article said that in case the ice cap of the Arctic is melting entirely, there would be no hope for this beautiful species. It's so sad...
