There are several different views on the species which would face extinction. Some have preferred to call the polar bear a "special concern species," saying that the evidence isn't strong enough to recommend threatened or endangered status. Others think climate change is a threat to the survival of the polar bear. In the end, the Committee on the Status of Endangered Wildlife in Canada examined 31 various species and concluded the ferruginous hawk should be upgraded to threatened from special concern, while two populations of the eastern foxsnake in Ontario are now considered endangered.
