that will pivot farmers from meat production, and animal feed production to produce. we will need much less land to cultivate, so rewild them. IE, just abandon them and let nature reclaim it.
I would argue, for the US, we should not rewild, but rematriate. Return the land to the tribes we stole it from and let them decide what to do next.
After all, Native Americans were the keystone species in every biome in North America for tens of thousands of years. Restoring the pre-Colombian ecology requires humans to occupy and manage the land. The myth of human-free American wilderness is settler colonial bullshit.
Nature is amazing!
