*sigh* a shame no one knows anything about my other thread "moritoriums on fisheries" but what about this one hahahaha
bringing an exterpated animal back to one of its original habitats? is it a good thing or a bad thing?
I know one good example and it was the wolves in a park that had all been whipped out because of farmers scared of their livestock and well to sum it all up they brought the wolf back to regain the balance with the herds of caribue and stuff like that .. as well as coyotes and foxes and smaller game as well as the plants around the park (I think it is Yellowstone park if I remember correctly)
so what are you're guys opinions on these type of things? is it good or bad to bring an animal back into an ecosystem that has been suffering with the loss???

Well, common sense would say that restoring natural loss would be a good thing. It's true that in Yellowstone that the reintroduction of the wolves has flourished the ecosystem; plants that scientists haven't seen in years have started growing again because the wolf has been preying on the ungulates that had been eating them. I believe a certain tree has now made a comeback because its saplings were always eaten. It's amazing how one thing can do so much.
It's not a good idea, however, to introduce animals into an environment to reduce numbers of an animal that they naturally prey on. Lampreys were introduced into one of the great lakes I think to prey on asian carp and have now grown out of control and the numbers keep growing. I may have gotten my facts mixed up there, but it's happened several times, without the thinking of scientists who introduce these animals.

These sorts of things must be thoroughly thought out and done responsibly.

If an environment will benefit from the return of a native species, then yes! definately a good thing.
Introducing foreign species into an environment? Makes me cry on the inside.
