While organic agriculture is better for the environment in some ways, one recent article finds that they are heavy machine users, and hence emit at least as much carbon as conventional farms. It'd be nice if the "organic" label system was more than a yes vs. no but had a 1-10 rating system or something so that farmers would have an incentive to improve, and buyers would know more about what they're getting.
That'd be much better than the GMO labeling that some people are excited about- why must we demonize what we don't understand?
