Good post Mickey Finn.??
Seem to remember this film, or one very similar was posted on here a while back. It does seem to have the promotion of wolf introduction as it's aim.
The idea that wolves change the behaviour of deer, and that can in turn dramatically alter the ecosystem, has been bought into in Scotland too. No wolves in Scotland though I hear you cry..., the solution is to have teams of volunteers wandering around the Caledonian forest howling like wolves! I sh!t you not ?
