This reads like a Rimworld post.
I don’t think there’s a Rimworld community on Lemmy and I’m not going on Reddit anymore so I’ll just throw this comment into the void and hope some fans are out there. 👋
Also in Rimworld terms the answer is corn (if monoculture) and send everyone to harvest at the first sign of blight.
But in both Rimworld and real life, a monoculture strategy isn’t sustainable. Diversifying via multiple food sources reduces your risk of disaster leading to starvation.
I remember this one from that one episode of House.
