Keith, I am forwarding this information I found very valuable.

There's a virtual consensus among "food economists" that eating healthfully at the bottom of the food chain (i.e. veganism or near vegetarianism) is the most sustainable way for the human population to eat, animal welfare issues aside. Here is a column on the subject by George Monbiot that makes the basic case. Seemingly the lone dissident, an agricultural academic named Steven Davis, favors a pastured ruminant omnivorous diet for the planet [see here]. He has been rebutted in this paper.
