A couple of years ago I shipped a container load of (organic) wine from France to New Zealand.

I was rather shocked to discover that assembling the 6000 bottles from the various regions (Bordeaux, Burgundy etc) to a warehouse in Marseille was more expensive than shipping them from there to Auckland (from memory, up to 20 euro-cents, and less than 10 cents, per bottle respectively).

So when people asked me if shipping stuff around the world wasn't contradictory with the idea of organics, I asked them if any of their organic food had ever travelled by truck.

Good point. A friend of mine maintains the carbon cost is less to ship timber from Latvia to London (3,900 miles) than it is to truck it down from Carlisle (300 miles).
That's interesting. I think people talking up relocalisation as a response to peak oil frequently fail to recognise just how incredibly efficient container shipping of non-perishable goods is.
