I can't really speak to what the first listener was talking about, about wrecking the world. I think that would be a little bit extreme. Beavers, like I said, wanted to start here that for seven and a half million odd years, they've been on this continent shaping and transforming it in different ways. And We, at one point, had between 100 and 400 million beavers across North America.
