We may never run out of food... but we will eventually run out of usable biomass for both buildings (As things tend to be going the biodegradable or "green" route now.), materials, and other things.. One must remember that we are essentially made from what we eat, literally. We are essentially topsoil, in the simplest sense, there is only so much "usable" material as a whole. Matter is not infinite. It exists as both intert and living things. we only have so much. And is it just food your thinking of? Think about water too... Then again, we got the ocean, and there are methods of making salt water into fresh water.
Although it would take years to exhaust those resources... but eventually, it will come to this- Whatever isnt human, is being used for food. All other animals will livestock... pets are only for the rich that can afford them, as that precious biomass is limited.
Materials are not infinite.
I was just talking about food, but you have done well to elaborate.
Yes we will eventually exhaust the natural resources of the planet, but this will take a long long time. Especially as our power generation is made more efficient and sustainable (fusion etc. - talking in the long term), leading to the cheap desalination of sea water for drinking.
And if worst comes to worst, who knows what technology the human race will have by then? We might just shoot off to the nearest habitable planet to either mine it for resources or colonise.

The truth is that we need to change our attitudes about breeding. There needs to be sincere attempts to control how many children you are able to have and who is allowed to have them. Overpopulation is a problem that our species exclusively controls by our blatant disregard for natural selection and the balance of this ecosystem. Our blind arrogance that implies our ownership of this planet will be the death of us, unless we get serious about stopping the breeders from continuously making more people that will depend on this already fragile ecosystem.
As I mentioned above, I think fossil fuels are the least of our worry in this case. This is going to be an extremely long term problem and thus I anticipate us developing energy in other ways.
As for selective breeding...
I can't really comment without my elitist and prejudiced views surfacing...
but I don't care.
It makes sense to me that high IQ parents should be encouraged to have more children and low IQ parents should be 'encouraged' to have less. I'm not sure if thats what you are getting at... but that's how it spoke to me.
For all I know you might want big people to be extinct so that those remaining consume less food.
