The numbers are increasing, but leveling off. High fertility rates only exist in a few regions of the world (Africa, South Asia) and even there they are falling rapidly. The "solution" broadly speaking is higher intensity - of energy, land, everything. If you have compact energy sources (nuclear) powering compact food production (high-yield agriculture, some vertical farming) feeding people living in compact cities (higher density, more ridesharing), then it's doable. You can already see lots of signs of this in the developed countries. This will still require lots of adjustment from people, but asking them to live in duplexes, share rides and eat less meat is much more doable than asking them no you know, not exist.
