Just two decades ago, there were practically zero wolves roaming the northern Rocky Mountains or western Great Lakes. But today, that number is over 6,000, and this good news has prompted the U.S. Interior Department to formalize plans to remove wolves from the Endangered Species Act. According to E&E News, this proposal would end federal recovery efforts and hand wolf management over to the states. Some environmentalists are predictably upset because they want continued federal protection for wolves, but since unmanaged wolf populations can threaten livestock and native wildlife, many experts think this is a wise move, and think Green leaders should stop “crying wolf” after this very successful recovery.
