Responsible meat-eating

^^ the same could be said for meat too though. Airlifted, not organic, many chemicals. It's not as if we raise a goat in the back yard that eats nothing but grass and underpants.
On a calorie to calorie basis, my guess is that the meat-as-a-product life-cycle produces far more waste that any plant.

^ Similarly, livestock production is a monoculture that relies on mono-cultures to feed it. Oliver mentioned earlier that majority of soy production goes on livestock feed.
