I appreciate you being upfront about the depth of your knowledge.

Regenerative farming and/or permaculture offer ways to run industrial-scale agriculture without the monoculture. See i.e. https://peercommunityjournal.org/articles/10.24072/pcjournal...

Another innovation I see is the use of "crop tunnels" (https://en.wikipedia.org/wiki/Polytunnel) to greatly extend the growing season in colder climates (another poster mentioned "Ohio"), and/or better control evaporation.
