If you have to put on a haz-mat suit to visit a farm, you may not want to eat what comes from it.
Joel SalatinIn my opinion, if there is one extremely legitimate use for petroleum besides running wood chippers and front-end loaders to handle compost, it's making plastic for season extension. It parks many of the trucks [for cross-country produce transportation]. With the trucks parked, greenhouses, tall tunnels, and more seasonal, localized eating, can we feed ourselves? We still have to answer that burning question.
