The Null Device

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."
