Crimes are what the state defines as crimes. - Daniel Quinn

This is precisely how someone speaks who imagines that he is the world’s divinely appointed ruler.

In spite of everything he said, I felt sure he was showing us that our population explosion is a social problem, like, say, crime or race schism. I failed to hear him say that our population explosion is a biological problem, that if we pursue a policy that would be fatal for any species, then it will fatal for us in exactly the same way. We can’t will it to be otherwise. We can’t say, “Well, yes, our civilization is built on an evolutionarily unstable strategy but we can make it work anyhow, because we’re humans.” The world will not make an exception for us. And of course what the Church teaches is that God will make an exception for us. God will let us behave in a way that would be fatal for any other species, will somehow “fix it” so we can live in a way that is in a very real sense of self-eliminating. That is like expecting God to make our airplanes fly even if they’re aerodynamically incapable of flight.

The world of the Takers is one vast prison, and except for a handful of Leavers scattered across the world, the entire human race is now inside that prison. During the last century every remaining Leaver people in North America was given a choice: to be exterminated or to accept imprisonment. Many chose imprisonment, but not many were actually capable of adjusting to prison life.
"Yes, that seems to be the case."
Ishmael fixed me with a drooping, moist eye. "Naturally a well-run prison must have a prison industry. I'm sure you see why."
"Well…it helps to keep the inmates busy, I suppose. Takes their minds off the boredom and futility of their lives."
"Yes. Can you name yours?"
"Our prison industry? Not offhand. I suppose it's obvious."
"Quite obvious, I would say."
I gave it some thought. "Consuming the world."
Ishmael nodded. "Got it on the first try."
