false comparison, as most calories cattle consume are from things people dont eat, even if there are simmilar variets of plants that both people and animals eat, they are not interchangable. Animals also eat huge quantities of human food, that has been rejected through some technical consideration, just size, as many crops produce many fruits or vegetables that are iether too large or small to be processed, or are misshapen or damaged, cow dont care nom nom nom, gone by the ton, and the trucks are still comming. The true unforgivable waste is by people over eating, wasting, throwing away, and destroying good foog for countless beurocratic reasons.
