However, as Arctic sea ice has retreated in past years, bears are forced to travel out further (and over much deeper and less productive water) to hunt from the ice edge. In the West Hudson Bay area, females are coming ashore up to three weeks earlier and thus losing valuable time to feed before denning. In both cases this leads to decreased weight and a decreased survival rate of cubs and older individuals. Years of sea ice decline correlate with population decline in the Hudson Bay and Beaufort Sea areas, trends which are most likely consistent with other polar bear populations around the world...%uFFFD(http://expertvoices.nsdl.org/polar/2008/10/17/polar-bears-and-climate-change/)
