The wolves and moose of Isle Royale are part of the longest predator-prey study in history. Recently, the wolf population has crashed, leaving only 2 wolves that are highly inbred. The only way new wolves can access Isle Royale is over an ice bridge across Lake Superior. With climate change, the ice bridges that used to form 80% of the time, now only have a 10% chance of forming, and the next ice bridge may be the last. Should our National Parks do something about the effects of climate change if they can?
