If wolves attack livestock or pets, do humans have the right to kill them, even if they're on the Endangered Species list? This long-standing debate has reached the states of Michigan and Wisconsin. Both states have requested permission from the U.S. Fish and Wildlife Service (FWS) to obtain permits allowing the killing of wolves, including gray wolves, which are protected under the federal Endangered Species Act. There are roughly 600 wolves in Michigan's Upper Peninsula. The FWS is accepting public comments on this issue through May 19.
