Is it about the size of the animal? Is there a large animal that produces enough meat to offset the environmental damage per serving? Chickens seem very gross and labor intensive for one family meal (unless you count eggs) where a cow seems happy to eat grass and produce a lot of meals. I realize most cows are disturbingly fattened and I’ve started trying to buy farm meat from local butchers. I think i read that Chipotle uses better (happier?) meat than most other restaurants. Also, i just started leaving about Temple Gramdin’s work for humane animal farming.
