This is silly. I love wildlife and nature. I'm against animal cruelty, but these animals don't belong there. Just shoot them.

Is there an equation "non belonging to an environment" === "rightfully being shot"? In such a case, I really hope you "belong" where you are now.

The hippos probably bring in tourism dollars, so that wouldn't be the most profitable solution.
