I support bringing them back. Wolves too. Bring back the balance. Nature knows the way.
A few people, cows, sheep, whatever, are all a tiny, tiny price in the big scheme of things, and I'd say that even if I, or one of my relatives, was one of the "people" I refer to. You really want "the wild" to be wild like it was and is supposed to be. Think long term.
Do it.
