We are what we are because of meat eating. Sorry #vegans and #vegetarians if you think your way is more natural you are sorely wrong. The #science is against you
Evolution only cares about survival of a species through procreation and being stronger than rivals. It doesn't care, for example, about longevity beyond the child-rearing stage of life, or about the environment. I quit eating red meat 40 years ago because it's better for the earth and, second, to avoid the old-age diseases that have felled my meat-eating peers, parents, and siblings.
