A new book claims that organic farming "poses the single greatest threat to natural ecosystems and biodiversity in human history" and that the organic food industry is using fear to manipulate eco-conscious consumers. The credibility of organics is in question, but so is the credibility of the book's author. Turns out he works for the Hudson Institute, a non-profit funded by the global agri-business and the biotech industry. Coincidently, a new guide for consumers rating pesticide loads on fruits and vegetables has been released. Guess which method, conventional or organic, rates best.
