> all other things being equal But all other things will never be equal because animal protein costs 10x more energy to produce. > what will happen to people when for reason there’s a problem in the supply chain of a specific crop or you have a bad year with low yields and the price goes to the roof? Have you been to a produce department? Most of them in the US could be reduced to 25% their current size and still have 200% the diversity of the meat department. Being unable to find one or more amino acids is just not a problem that vegetarians have. The problem is constantly having to cook for yourself because vegetarian options at most restaurants (or prepared by well-meaning carnivore friends) are just "leave the meat off" and not designed from the ground up to be nutritional without meat. Cultural change would make it easy.
