Low information strikes again when people reduce meat eating to a neat little slice of steak on their plate and extrapolate that back onto humanity for thousands of years. People hunted and raised animals for thousands of years for the WHOLE animal. People could not survive without the skin, bones, hooves, sinews, organs, teeth, and not to mention the thousands of religions using them for worship practices. Ppl have always lived animal based LIVES. Not just diets.
