James E. McWilliams wrote in a recent NYT Op-Ed, “The Myth of Sustainable Meat,” that consuming animal products can never be sustainable, even when approached with an eye toward ecology. He breaks out his calculator, multiplying the number of cows that Americans currently eat by the number of acres required to farm them responsibly. The result: an impossible amount of grazing land, among other problems. I normally expect this tone from guardians of the status quo who dismiss organic farming as inefficient or naive. What I didn’t expect was McWilliams’s suggestion: Stop creating animal products. He pits sustainability-minded omnivores not just against industrial farming, but against herbivores. His argument is so snide and riddled with flaws that it distracts us from his conclusions. It also points to a rift within the sustainable food movement. Can omnivores and herbivores talk to each other about food issues? And can a Jewish perspective help us through this seemingly intractable conflict?
