How will global warming effect the polar bears? Inspired by this question:
http://answers.yahoo.com/question/index;...

they will be trapped between the melting ice and the oil prospectors moving north. in previous interglacials, there was no competition from people, as sewing had not been invented and we hadn%26#039;t got up to the cold places yet.
they will eat berries etc. but couldn%26#039;t live on them sucessfully like their cousins the brown bear as they have evolved to eat meat and are a lot bigger.

they won%26#039;t have ice to cruise around on in 10 - 15 years

Well, considering their numbers have been shown to be increasing and they%26#039;re not on the verge of extinction, I%26#039;d say they%26#039;re doing alright.

It really won%26#039;t make them die.

The bears are getting angry... and they%26#039;re organizing.

ice will melt

They, as well as Santa, survived the last warming period. They%26#039;ll survive this one.

Polar bears enviromont consists of large iceburgs that they live and fish on. Unfortunatley, global warming is causing those iceburgs to melt and break of the ice. Polar bears a beginning to starve because they cannot get to their food, and if all the ice melts, that means all polar bears die. Good question, though. :)

heat melts ice...... their not called polar bears for nothing..... they depend on the ice..... polar bears live on the ice... as the temperature increases, more and more of the polar ice melts thus leaving polar bears hanging in open water.... even though polar bears are exceptional swimmers, they get tired too and drown..... discovery channel can back me up with this.....

Global Warming probably wont effect the polar bears because the earth has been heating and cooling for years and if there was only 1 ice age millions of years ago when there weren%26#039;t humans around how do we effect it?
