Good thinking. It burns much more fuel when farmers individually go to a farmer’s market or supply a local store than having one large truck doing the same job but going from farm to farm to collect the produce. Sure, it takes something away from the romantic idea of local markets and producing food locally, and it almost sounds counter-intuitive in that context. But, if you wanna be sustainable, going back to the old ways of produce distribution puts more pressure on the environment than using more modern, streamlined methods. After all, the model of farmers going to the market individually comes down to us from a time where where fuel for transport consisted of feed for horses – very different pollution levels there.
