> Well, you're missing the part where many acres of vegetable crops are inputs into that single acre of pork What do you mean by vegetable? It is a rather loaded term. Culinary vegetables are definitely not fed to pigs in any meaningful quantities. They are much too inefficient to even consider. If by vegetable you mean any kind of edible plant, then yes, pigs are fed mostly very-efficient-to-produce corn and soybeans. Based on the numbers before, when you feed pigs 15 million calories of corn (1 acre), they give back 3.5 million calories of pork. If you fed pigs 2 million calories of broccoli (1 acre) then they would likely only give back 0.4 million calories of pork. But that's a really big reason why you don't normally feed pigs broccoli. > Animal meat is nowhere near as efficient as eating vegetable crops directly Agreed, if you are talking about the specific vegetable the animal is eating. However, vegetative efficiency varies greatly from crop to crop. If you feed animals the most efficient plants, then they can still be more efficient overall than the less efficient vegetables are alone. As before, the food the animals eat is, for all intents and purposes, not the same food that you eat. Plants that are intended to be fed to humans are generally less efficient to produce, for various reasons.
