I watched one of those discovery channel shows a few years ago that was about container ships, or something. They made the point that it was cheaper to move a container from Shanghai to Hamburg than it was to then put that container on a truck and send it 100km down the road. Economies of scale.
In terms of fruit and vege, I recall seeing farms out near Fairbarn Dam near emerald that were supposedly producing fruit 365 days a year due to climate and water availability and sending out 5-10 semi loads a week or a day (iirc). That was in the mid90s.
Global economy and expanding populations mean that local seasonal fruit and vege is a thing of the past. The downside of the financial worlds constant growth model. More people requires scale and efficiency in feeding them.
The one I saw recently was talking about UK ports and how cheap it was to ship the container compared to trucking it 20km down the road. It is amazing.
