most cows mostly eat grass. what crops are given to livestock is usually plants (or parts of plants) that people can’t or won’t eat.
Most cows eat grass. True. But most cows are fed grains, not grass.
So growing grain, using the seeds for feeding humans and using the rest for raising additional food for humans is a good idea and was practiced for millenia. But this way our ancestors got a pig or a cow per year per family, not a steak a day.
i never said they aren’t. i’m saying the bulk of what makes a cow is grass. grain finishing isn’t that big of a deal (in my opinion). certainly, the whole food system accounts for ~20% of our emissions, so we could be focused on other sectors instead of food which people eat.
