The opposite of consumption isn't thrift. It's generosity.

When you have weird policy decisions in the United States that then ripple out throughout the world, the rest of the world really takes it on the chin. When the U.S. decides to set their corn on fire rather than to eat it, which is what the biofuels policy basically is - then that drives up the price of corn. It drives up the price of substitutes. And all of a sudden you have a sort of spiral of food prices. And other countries don't have the resources, because they're not allowed to, to weather the storm.

There are two novels that can transform a bookish 14-year-old's life: The Lord of the Rings and Atlas Shrugged. One is a childish daydream that can lead to an emotionally stunted, socially crippled adulthood ...in which large chunks of the day are spent inventing ways to make real life more like a fantasy novel. The other is a book about orcs.

All of human history is about the going from sudden fat years to the sudden lean years. We've always had good times and bad, and we've had ways of managing the bad times. We have ways of insulating ourselves, making ourselves less sensitive for the bad times by having things like grain stores, for example. Pretty much every civilization that's lasted for any reasonable length of time has some food management principles behind it. But what's been happening over the past thirty years is it's failed - the insurance policy.

One of the most abused country on earth is Mexico. The marketing spills over the border, and people are persuaded to eat food that's bad for them, more in rich countries than in poor ones. I was traveling the world. What really struck me was the way we engage with food - how it's a global phenomenon - the world becoming more and more disconnected from it.

Right now you're seeing more and more families reporting that they are skipping meals. They're having to give up meat. Mothers are foregoing food so their kids can have something. People are growing their own vegetables, not because they've gone organic, but because it's one of the few assured sources of food they have. For low-income Americans food is costly right now. The price of food has been going up, and wages haven't. This puts working Americans in a real bind. The fact that the mainstream media hasn't reported it doesn't mean that it's not happening.

We kind of know that food is necessary to survive. But our ways of connecting with food have been, in many ways, taken over by capitalism - certainly taken over by the influence large corporations have on the way that we eat and the way that we think about food. That's why kids these days are more prepared to take nutritional advice from Ronald McDonald than they are from their parents or their teachers or from scientists. And particularly in urban areas, you'll see kids who honestly believe tomatoes come from the supermarket rather than from a plant.
