To boost production, many farmers inject cows with synthetic growth hormones, which increase the cows' risk of developing mastitis, a painful infection that causes cows' udders to become so heavy that they sometimes drag on the ground. Cows are artificially inseminated. Calves are traumatically taken from them shortly after birth. Humans are the only creatures that drink milk from the mother of another species.
Many children are subtly or violently allergic to milk proteins.
Soy formula is far easier on babies' digestive systems than cow's milk.
