Zoo Safety a Concern?

Concerns have been raised over the past few days regarding the safety of public zoos after a woman was attacked by a polar bear at the Berlin Zoo last week. According to AP, "The woman, who has not been identified, climbed down a fence, over a wide hedge full of thorns and got past a concrete wall before swan diving into the murky moat where the polar bears swim." This is the second time in the past 6 months that this happened...at the same zoo...in the same exhibit. Republicans say, "...as long as the Obama Administration continues to focus on global warming, the Polar Bears will continue to terrorize our zoos!"
