Isle Royale National Park in Michigan has a problem. In 2009, twenty-four gray wolves lived on the island. In 2014, only nine remained. Scientists have noted that many of the wolves have birth defects that may be impeding their ability to reproduce. Some scientists have suggested importing gray wolves from other areas to the island to help rebuild the population. Others disagree. Because wolves hunt moose, they think more wolves will mean fewer moose.
