Alaska polar bear sightseeing rise

USA Today reports on Alaska's boom in polar bear tourism.

It's not hard to understand the allure of these giant white bears. Regal and majestic, but also somehow cuddly, there is a natural magnetism that draws us. Add the sense that their future is in doubt, and it translates into heightened public interest in seeing bears. Worldwide, there are 19 known polar bear populations, according to the U.S. Fish and Wildlife Service. Two are in Alaska— the other is in the Chukchi Sea on the western coast.
