Answered by polar bear scientist Scott Schliebe of the U.S. Fish & Wildlife Service. "Although it may seem an obvious solution, the risks outweigh the benefits."
Q. I am writing concerning the plight of polar bears due to sea-ice loss in the Arctic. It occurs to me that one possible way out, that I have not so far seen considered, is simply to move a sufficient number of polar bears to a promising spot on the Antarctic ice pack where the species might get a fresh start. Some areas seem to abound with seals. I can imagine there would problems in transporting them, but I have never seen consideration of this simple approach.
A. This question comes up from time to time from well-intending individuals. While intuitively the initial concept may seem to have merit, a closer examination indicates that it is not a simple solution and includes a great deal of downside risk. I believe it would be unwise to translocate or introduce polar bears into Antarctica for a number of reasons, some of which follow.
