It is nice that zoos are creating modern polar bear exhibits that can house multiple bears. However, there has also been two deaths in the U.S. recently and the current U.S. polar bear population is small. Part of me wonders if polar bears in outdated exhibits should be the candidates to go to these new exhibits. But, some are old so they will probably stay put. On the bright side, there's more choices of future locations for the four polar cubs born recently.
