Crops can blight, animals can get diseases. I don't know much about hydroponics but I know that bacteria are a concern. What food source is the most reliable, the least likely to produce less food than expected?

I know you’re not really being serious, but it doesn’t really. I considered the logistics of this for an RP I was running and it doesn’t add up. You need way way way way more food to grow a human being than the human being provides in food when they’re dead. At most, being very very generous, you could meet 1% of a society’s food needs with cannibalism. And that’s a really high estimate. It’s really more of a special treat than a daily diet!

Conservation of energy, basically. A self-eating population is a perpetual motion machine.
