I try not to think about all that though, because I like meat and couldn't imagine trying to be vegetarian.
This increases the yield and efficiency of food production. If this was not so we would be living in a vastly different world with a lot fewer people where basic needs would require a lot more of our effort. On the other hand we have plenty to do to cut down unnecessarily long trips in oversized vehicles from oversized houses before we worry about how much fuel we use on necessities.
