Crops can blight, animals can get diseases. I donβt 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?
Pretty sure thatβs actually just a reference to the film Soylent Greenβ¦
Theyβre making our food out of people, next thing theyβll be breeding us like cattle! for food!
I know youβre not really being serious, but it doesnβt really. I considered the logistics of this for an RP I was running and it doesnβt add up. You need way way way way more food to grow a human being than the human being provides in food when theyβre dead. At most, being very very generous, you could meet 1% of a societyβs food needs with cannibalism. And thatβs a really high estimate. Itβs really more of a special treat than a daily diet!
Itβs so inefficient you may as well just leave the population to starve, nearly the same effect for much less work!
