How would people produce food after the apocalypse?
Imagine the supply chain is completely gone. A small community has to survive on its own, but farming is difficult because water is limited, usable land is scarce, and going too far outside the settlement is dangerous because of monsters and roaming groups.
How do you think people would realistically produce enough food to survive long-term?
And what would you trade for 1 pound of rice, wheat, or potatoes?
