US scientists have predicted that over two-thirds of the Polar Bear population will die by 2050 because of global warming. In that time, the polar bears will lose access to as much as 42 percent of their hunting and breeding grounds.

U.S. Geological Survey (USGS) scientist Steven Amstrup pointed out that what will drive these polar bears to their deaths is mainly the declining sea ice due to increasing temperatures. It's actually very logical if you think about it considering polar bears use the ice as a staging area to hunt seals, their primary food source.

Will reducing greenhouse gas emissions help? Not much, according to USGS's director Mark Myers. He said that "despite any mitigation of greenhouse gases, we are going to see the same amount of energy in the system the next 20, 30 or 40 years." Don't think that nothing is being done to counteract this, though. Interior Secretary Dirk Kempthorne's agency has already proposed to add the polar bear to the endangered species list which should help alleviate the problem.

All the information that was gathered are based on six months of data where the health of three polar bear groups and their dependency on Arctic sea ice were documented and analyzed. However, it is all pretty much theoretical at this point. That being said, are we going to have to wait and see if it will come true before we act on it?
