I think phosphorus will ultimately be the limiting resource, and I'm guessing 20-30 billion will be about where things level off.

So it's all hinging on the fact that population is currently growing exponentially?

We know that it can't go on like that forever. We know there's a finite amount of resources on this planet, and that they can only sustain a certain population. There are laws of nature which do - which have ALWAYS governed this though, and are well understood in the world of biology. Do you ever see an animal population modeled exponentially in the long term? No. You figure out which factor (be it competition over resources or territory or what have you) will limit the population, and you write a logistic growth model instead.

The same will apply to humanity. It's inevitable.
