Vanishing Species?
Think the polar bear has it bad? Here are 10 critters that are even worse off than our favorite threatened Arctic resident. Listed on the International Union for Conservation of Nature's (IUCN) Red List as critically endangered, meaning they face an extremely high risk of extinction in the immediate future, these animals may not live to see the end of the next decade without the a similar effort of human intervention that brought them to the brink in the first place.
