Let's assume a human decides to eat grasshoppers. How many people could the grasshoppers feed compare to the chickens?
A human requires 1 chicken/day
a chicken eats 25 grasshopper/day
1 grasshopper requires about 30 g of soybeans/year
1,000 grasshoppers have a mass of 1 kg
1 human requires about 600 grasshoppers/day
dry soybeans have 3.3 cal/g
a typical human requires 3,000 cal/day
