They did say there were nonviolent ways of handling the problem. I think they could be tranquilized and relocated or tranquilized, sterilized and then relocated. There's a variety of methods to control populations.
I like the idea of sterilization and relocation myself.
I don't like the idea of humans deep in the wilderness because as human populations increase, there is less and less land left for nature. Now, if human populations stabilize that's a different story.
