It could be the bears get creamed on the highway, "But after being trapped and flown more than 300 kilometres from Fort McPherson to the coast, it seems the bear simply turned around and started walking south again." http://www.cbc.ca/canada/story/2007/09/01/polar-bear.html or folks on the Yukon Delta got mad at them for eating the moose swimming in the ocean (we had a polar bear down here on the coast a few years ago.) Polar bears won't "revert" to grizzlies but I wouldn't write them off just yet. However, competition with grizzlies in adapting to the same changing environment, e.g., as they do around Prudhoe, may be fierce.
