From the New York Times, The Range Gets Crowded for Natural Beef. Lots of conflation between "natural" and "organic" in this article, and very little mention of grass-fed beef. The article talks about the higher cost of organic feed, but doesn't go into the fact that that feed is still corn, and that cows don't eat corn except when we force them to. I guess because it's from the business section its focus is the booming organic food industry.
