You may not be in San Diego, but you might be able to get an idea of how Polar Bears live without watching Sarah Palin's Alaska. Imagine that!
Earlier this year, the San Diego Zoo opened its renovated Polar Bear Plunge exhibit.
The San Diego Union-Tribune has an informative story, with drawings and photos, about the opening of the exhibit. The newspaper's Polar Bear topic has links to stories, photos and videos of polar bears.
The zoo itself has an interactive website, Conrad Preby's Polar Bear Plunge, which will be interesting to kids of all ages. There is a "Polar Bear Cam," but nothing can be seen right now, perhaps because it's dark. When you get there, just move your mouse around to explore the options.
Polar bears are threatened by global warming, and one of the exhibit's purposes is to educate its visitors about the problem.
I don't know whether Palin's show will have any polar bear footage. If it does, it's virtually certain that the bears' problems won't be attributed to global warning.
