This is very dangerous. If Otter doesn’t take care of wolves, the population of elk could grow unchecked. If elk population is unchecked, there will be too much elk dung. If there is too much elk dung, this elk dung will cause be man-made global warming. If there is man-made global warming sea levels will rise. If sea levels rise, the polar bears will drown and New York City will go underwater. The only way to prevent this scenario is to raise taxes and use the money to buy carbon credits from Al Gore.

No, no, you got that wrong. We need an explosion in the tasty elk population. We eat them here in Idaho. Harvesting more elk will reduce the pressure to raise those inferior tasting bovine. Less bovine farts, less imagined global warming. Besides, New York City will make good fish habitat.
Obviously elk dung production will have to be strictly controlled.
A .30-06 should be adequate for the purpose, although YMMV.
So far your scenario is all pony and no horseshit. I'm still looking for the problem. Oh, I see, the good parts of the country infested with refugee New Yawkers. You have a point.
