I think you're dead right in all that, but there is a lot of “if's”.
If humans carry on as they are (ie pretty well uncontrolled), then one of two things will happen:
We'll get a Malthusian population crash when finite resources run out;Or, we'll end up as you predict, with the entire Earth essentially one single farm, supporting us alone.The second of these requires a total understanding of genetics and a complete mastery of genetic engineering. The reason is that we must be able to cope with the implications of zero genetic diversity. For example, climate change might force us to literally construct drought-resistant wheat, since we couldn't use selective breeding. Similarly with pharmaceuticals needed to resist mutated pathogens. The implications of this mastery are, of course, profound, because they will also apply to humans themselves.
The ultimate barrier to human development on a single planet is not climate change or resources; it is heat dispersion. Eventually, the planet will become too hot to be worth inhabiting any longer.
