Video: Polar Bears Deemed Threatened

I am trying to catch up with the National Geographic RSS Feed. Last week, Polar Bears were placed on the Endangered Species list by the U.S. Government. I watched this video with a bit of amazement.

If I am understanding it correctly, polar bears have more than doubled in numbers in the last 30 years. But because of studies that promote global warming, there is concern that in the decades ahead, the polar bear population could be decreased by 2/3...

Now, I am all for looking ahead and trying to fix problems on the front end, instead of waiting for hind sight to kick in. But, I am wondering where this stops. It is too reminiscent of Minority Report to suit my tastes. What are your thoughts?
