I'm sorry but until all (or even any one) of the Organic Farming Associations can say something better than "Organically grown foods are AS HEALTHY and AS NUTRITIOUS as foods grown using more modern methods of agriculture" I have to wonder if the "benefits" justify the added burdon placed on the environment in the form of deforestation, erosion, etc.
To quote the article: "Unfortunately for the organic customers, no consistent, significant nutritional advantages have EVER (emphasis added) been documented in organic food, during the more than 75 years since a German racial purist named Rudoph Steiner first dreamed up the organic concept in the 1920s."
Just a couple of on-line articles for you to peruse at your leisure. I'd challenge anyone to show that sustainable agriculture is bad for the land. If anything, (and this is just my belief) the pesticides and herbicides used today have leached our soil of any value. Bad analogy - let's say you eat an organic apple. To get the same nutritional value from a non-organic apple, you'd need to eat 3 of them. Yes, there's no question that organic food costs more. But, I've kept my gorcery budget the same. I may bring home "less" food, but the food I do bring home is of much better quality and much more nutricious.
