Since the 1970’s, sea ice in Canada’s western Hudson Bay has declined noticeably, alarming some about the fate of polar bears in the region. Now come two studies indicating such fears were unfounded. As reported in the Journal of Wildlife Management, scientists from Ontario’s Lakewood University as well as the US Geological Survey have discovered that polar bear numbers, far from being depleted by alleged global warming, are actually increasing at a rapid rate. In 1993 there were 1,400 polar bears in the region. Today that number has hit nearly 2,200. In fact the increase in bears has created a new worry for scientists: namely that there are too many of them, now exceeding the area’s carrying capacity.
