It's not food if it arrived through the window of your car.

Imagine for a moment if we once again knew, strictly as a matter of course, these few unremarkable things: What it is we're eating. Where it came from. How it found its way to our table. And what, in a true accounting, it really cost.

Our ingenuity in feeding ourselves is prodigious, but at various points our technologies come into conflict with nature's ways of doing things, as when we seek to maximize efficiency by planting crops or raising animals in vast mono-cultures. This is something nature never does, always and for good reasons practicing diversity instead. A great many of the health and environmental problems created by our food system owe to our attempts to oversimplify nature's complexities, at both the growing and the eating ends of our food chain.

The best farming systems are ones where animals and plants are put into a synergistic relationship.

To ferment your own food is to lodge a small but eloquent protest - on behalf of the senses and the microbes - against the homogenization of flavors and food experiences now rolling like a great, undifferentiated lawn across the globe.

We could have a greener economy, even a greener consumer economy by changing the rules - whether it's by taxing carbon or trading carbon, I'm not sure what - but in the end there's just a fundamental problem with the sheer amount we're consuming.

You want to say the thing that will drive everybody in the direction you want to go. But as a writer you have a pact with your readers that you'll be really straight with them at all times.
