Question, list-members!

I remember seeing an analysis once that demonstrated that world
vegetarianism would be far more destructive to the environment than
carnivory, and far more costly, due to the need to use extensive amounts of
fertilizer, to destroy native ecosystems, and to ship plant matter (and
concentrated vitamin extracts) to populations living in areas that can't
grow the proper variety of plants needed for full health. Unfortunately, I
don't remember where I saw it. Any of you know of such a study?
