Polar bears, penguins: choose one
As the north polar ice cap shrinks, some scientists are thinking that the last chance of saving polar bears may be by relocating them to Antarctica
. Others are wary of this:
"Antarctic penguins and seals aren't adapted to surface predators," explained Steven Amstrup, the chief U.S. Geological Survey polar-bear researcher. "The bears would have a field day for a while, because they could walk right up to them and eat them. For a short period of time, it would be great, but in the end the whole system would probably collapse."
