Came across this website: http://www.earthfarmfriendly.com/cer...n_elements.htm and thought it was kind of interesting. This is a group that will give you an "earth friendly" certification as long as you use bovine growth hormone, milk 3X day and keep the herd confined.

Their theory seems to be to maximize production and feed conversion efficiency so that there don't need to be as many cows, farmers or farms and then allow the surplus farmland to be put to other uses.
