A couple of months ago, Coco raised a great question when I was riffing about the amusing implications of shipping lettuce from the Imperial Valley to Albuquerque so I could feed it to ants:
Not enough water to grow lettuce in the Middle Rio Grande? Maybe someday. Depends.
Someday, not enough cheap oil for schlepping lettuce from the imperial Valley. That’s more certain.
So here’s my lazyweb question. What portion of the cost of a head of lettuce at the local UberMart can be attributed to the fuel needed to ship it from California to Albuquerque? And how sensitive, therefore, is the cost of that lettuce to, say, a doubling of the cost of that fuel?
