It's funny living in the breadbasket--I drive past miles and miles of corn and soybean fields, where much of our "food" comes from, and none of it is edible without extensive processing.
I'm with Frank on not seeing the connection with the rant about trucks. When it comes down to it, our food comes from lots of sun, some water, and a fair amount of petroleum in planting, harvesting, transport, fertilization and pesticide/herbicide application. Sunlight is free, water isn't likely to be a problem in the long term here (based on current climate models), but the reliance on petroleum is a little unnerving.
