It's good for those animals, but bad for humans, simply because humans and animals have different kinds of bodies.ur saying that breast milk that is produced naturally organically by every mother of every animal species for its young is bad?
Human mothers' milk is good and sufficient for human babies.can u think of anything thats more nutrients and packed with all kinds of vitamins and antibodies and hormones and whatnot that all children and babies need it to grow and develop every function of their bodies and brains,nothing can even come close to mothers milk or any other substitute of milk.
It's also good for human adults, but not sufficient.
