Do you realy believe there will not be enough ice for polar bears to survive where they have for thousands of years. The earth has been through warm spells before and polar bears survived. I have heard a couple of reports this year of ships needing to be rescued by icebreakers after being told that there was no ice in those areas due to global warming.
I think polar bears would like the antartic until they ate ALL the penguins. Imagine a polar bear in a King penguin rookerie.
Hasn't anyone seen those Coca-Cola commericals with dancing penguins and polar bears sipping soda drinks? There already are bears at the South Pole...hahaha.
Yes, the ice caps are melting which is very unfortunate but fortunately hunting is extremly rare these days, which has made the population grow over the last few years, but over the next decades or so the population might go because of us destroying their home,
