Just 2 or 3 degrees increase in the temperature of the arctic waters is causing ice to melt, just like the scientists said it would (and the US gov’t world turned a blind eye). This is becoming a big problem for polar bears. These creatures are mammals and cannot breathe under water. When they come up for air they must tread water to keep their head up until they get to ice or land. If the ice can no longer support their weight because it has melted or if it melts altogether there is no rest for the polar bears to rest and they die of exhaustion – they drown.
There are only about 25,000 polar bears on the planet and Wrangel Island, north of the Bering Strait, is the main place they can be found because this is their breeding ground. To learn more, go to:

I also found a student YouTube that gets right to the point, though I'm not sure there numbers are quit right. Still that doesn't change the fact that poalr bears have got a problem. You can find there video at:

OK, now for my stupid solution (cuz I can’t turn off all the other people’s bad habits): Let’s gather up several thousand old surf boards and drop them into the water near the island. The bears can use them to rest on when the ice is too thin to stand on, or too far away. This is temporary, but maybe the bears could survive this way until we figure out what else to do.
Whadaya think?
