Does lead to an interesting question though. Usually the efficiency of
agriculture is based in energy per unit area, and on that basis
vegetarianism is a clear winner. But humans don't just need energy--if that
was all we needed we could survive fine on a diet of pure sugar. On that
basis, which is more efficient in producing complete protein, plants or cows
eating plants?
