Like this is more unnatural than penning calves in a tiny kennel where they can't even turn around, pumping them full of antibiotics because it's more efficient than actual hygiene, injecting them full of hormones to get them as big as fast possible, and then killing them at 6 months or so?
I read a book not too long ago (forget title) in which one of the main characters was geneticist who developed a cow with no head. It had a breathing and a feeding tube instead. Meat- tree is what he named it.
