Unless of course these are non-swimming polar bears.
And if they are, it's Bush's fault for not building swimming pools in the neighborhoods where these deprived creatures have to live.
To me, it looks like these polar bears have gotten themselves into a fix. They obviously do not know how to survive in these hostile natural conditions. We need to capture them and put them in a zoo where they will be safe from mother nature.
Remember...global warming experts don't know a dang thing about bears (or the relationship of the earth to the sun either). So if they tell you that bears can't swim....you ought to ask them if thats a fact. Have a global warming dude stand on a ice flow about 50 feet away from the polar bear and lets test the global warming expert. If the bear chomps on him in three minutes....then he was proven wrong....and if it takes the bear over 15 minutes to swim 50 feet...then we will admit we were wrong...after the bear finshes with him of course.
