We're already way beyond the carrying capacity of the planet, without fossil fuel inputs.

There are only two options:

1. Split more nuclei, fuse nuclei at +EROEI, and collect more photons.

2. 4 billion people starve to death.

Population control was a fun idea in the 1970s, but that ship has already sailed. We either experience mass die-offs, or we engineer our way out. Full stop.
