Good news in the country I'm living in though, it seems the wolf is returning. There have been confirmed rapports of a wolf being spotted recently. I think it's the second wolf spotted. Not too sure. Either way, no plans to kill the wolves, they would even be welcomed, as we have no natural enemies to deer here, so we kind of have a deer infestationn because they whiped out 'accidentaly' the wolves hundreds of years ago or so.
I do know that in highly radioactive areas where it's impossible to live for humans without experiencing nasty side-effects, wolves and other animals can roam freely. Experiments, tests and observations have been done, and the animal population is healthy and not suffering any negative side-effect from the radio activity. And no, they did not mutate to large zombie dogs or anything
Nature will find a way, we just need to give it time.
