"Locavorism" and the Environment

"Buying local" is not necessarily buying green:

...lamb raised on New Zealand’s clover-choked pastures and shipped 11,000 miles by boat to Britain produced 1,520 pounds of carbon dioxide emissions per ton while British lamb produced 6,280 pounds of carbon dioxide per ton, in part because poorer British pastures force farmers to use feed. In other words, it is four times more energy-efficient for Londoners to buy lamb imported from the other side of the world than to buy it from a producer in their backyard.

Nor is knowing the producer necessarily good for the community:

Historically, such personalized economic transactions were the norm, but they were inherently fraught with risk and tension. In colonial America — a place I’ve studied in some depth — all markets were initially driven by face-to-face interaction. It should come as no surprise that things could get, well, personal. Markets were intensely competitive and exclusive. Everyone knew everyone. And that was often the problem. The court records of colonial New England are replete with personal market transactions gone awry.

Food for thought, so to speak. Trade is good.
