(AP) - This undated photo provided by the U.S. Geological Survey shows a collared polar bear with her cub walking on the ice in Alaska. Alaska Gov. Sean Parnell says he has the best interest of polar bears at heart, but he doesn't intend to let the federal government's expanded protection for bears get in the way of the state's continued prosperity. Like his predecessor, Sarah Palin, the governor is suing the federal government to overturn the listing of the iconic symbol of the Arctic as a threatened species, a move made last year that he believes could threaten Alaska's lifeblood: petroleum development.
