You skipped over everything I&#x27;ve referenced and introduced a completely new narrative which has a simple rebuttal.<p>We waste tons of grains to filter through cows&#x27; bodies. Cows produce waste, that waste is used to replenish the land with minerals needed for grain growth.<p>Now, wouldn&#x27;t the same thing be possible without filtering that waste through animals, keeping the waste in high amounts, suitable for the grain agriculture?<p>Of course, there&#x27;s absolutely nothing magical in cow&#x27;s butt that produces the necessary fertilizer. You can fertilize land with vegetable waste, producing less pollution and less non-recyclable waste, needing less energy.<p>The animal component is completely unecessary.<p>If you&#x27;re trying to find rationality of these industries look at this narrative.<p>People hunted animals, they survived because of animals, but why did they do it, instead of just picking berries, raising food?<p>It was a time-saving heuristic. The animals were free, the animals were collecting nutrients, packing them into their bodies, and all that time was saved for the human. Humans just &quot;collected&quot; the neatly packed nutrients and had concrete savings.<p>Today, we bring the food to animals, we center everything around their food filtering, from an energetic, sustainable, environmental perspective it isn&#x27;t equivalent, it&#x27;s not even close. It is irrational. This irrationality is closely linked with our desire of excessive luxury.<p>From all the given evidence, dropping this would save us billions if not trillions in environmental cleanups, health-care bills etc.<p>Currently, there&#x27;s nothing magical in animals that necessitates our use of them. The magic has disappeared when we snatched the planet.
