When Matheny recalculates using Davis’ formula he finds that “to obtain the 20 kilograms of protein per year recommended for adults, a vegan would kill 0.3 wild animals annually, a lacto-vegetarian would kill 0.39 wild animals, while a Davis-style omnivore would kill 1.5 wild animals. Thus, correcting for Davis’s math, we see that a vegan population would kill the fewest number of wild animals, followed closely by a lacto-vegetarian population.”
