Also the math for material output of a cow vs an almond tree is pretty fucking different. For the almond tree it’s basically just the almonds, I guess you probably do something with the wood but I don’t know if it’s all that useful. Where as a cow damned near every part of it is usable hide can be turned into leather, every bit of meat can be eaten, their bones can be used for a whole host of things, and their shit makes for decent fertilizer, also milk. Fact of the matter is the cow is far more useful for its materials.
