I think that working out how resilient food technologies could be scaled up in a catastrophe such as nuclear winter is legible and concrete, including natural gas (methane) protein, hydrogen protein, greenhouses, seaweed, leaf protein concentrate, fat from petroleum, relocating cool tolerant crops, etc. Indeed, a survey and a poll have indicated that this work has reduced existential risk.
