Oil or water?

I thought that Kingsolver made an interesting point about agriculture and eating local foods and their impact on resources.  I think oil is the resource that pops into most people's minds when talking about mass quantities being used at the expense of manufacturing, transporting, and all of processing foods.  It differs geographically and regionally, though.  She makes the point that in the middle of a drought she either had to choose between buying food that was using up Arizona's water or food that was guzzling up international gas.  It's an interesting concept to think that depending where you are and what kind of situation you are in, there is no one "correct" way to where and how you get your food because while you may change how you get it to preserve one resource, you are probably just tapping into another more local resource, or just a different one.  Everything comes with a cost, it just depends where the biggest footprint is going to be left.  I also found it astonishing that if everyone in the U.S. had just one meal a week that was local and organic, it could reduce oil consumption by 1.1 million barrels per week.  That is really crazy to think about.
