Reminds me of the (supposed) benefits of reintroducing wolves at Yellowstone; they reduced and got the elk population moving, reducing overgrazing, helping beavers recover, and helping rivers and biodiversity to recover.
Of course, that's Yellowstone which is a lot bigger and not populated by people. Wolves are returning (or, being allowed to return) to the Netherlands as well where they end up decimating sheep populations for the fun of it, much to the chagrin of farmers.
