Sure Magnus, I know there's a huge grey area. As John Darnell (R. Barlett's advisor) said in his lecture at the NYC PO Conference in Oct. "We need to envision the world that is sustainable and work our way backward on how we get there." I don't think large scale livestock farms are part of that sustainable future so efforts to prop it up seem like a waste of time and energy to me. It's really the idea of subsidizing them that gets to me.
