Yet if you go to the supermarket and look at food that's produced through industrial agriculture, look at what's happened to the prices. Have they been going down? They've been going up and they will continue to go up. So the choice is either, do we hitch onto a system of agriculture that's doomed and will doom the planet with it, and go along the route of industrial agriculture, or do we want to shift to a kind of system that we know is going to be, in the long run, cheaper, because we'll have a planet left at the end of it? We need to factor that cost in.

There isn't enough planet for everyone to eat as much meat as the United States does. The meat industry is responsible for a dead zone the size of New Jersey in the Gulf of Mexico every year because of the runoff through the Mississippi - runoff from hog farms basically nukes the water.

The problem is that we are living now with the consequences of the others people mistake. It would be nice to make our own and learn from them. That is the art of democracy. That is the art of citizenship.

A recent review of different agricultural options for the future was conducted by a panel of experts. The scientists posed the question: How are we going to feed the world when there are nine billion people on it, as there will be by 2050? And the answer they came up with was industrial agriculture won't work and genetic engineering won't work and the solution is going to be sustainable, and going to ecological kinds of farming that are based on local environmental conditions that work with local ecosystems available to develop a richer kind of farming technology.

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.

India has the largest number of hungry people. Yet it's an outcome of precisely the same mechanism. It's the control of agriculture that drives down the price it paid for food that it buys from farmers, who are the poorest people. Then you're paying very little for food. You're underpaying the poorest people in any society. Then they're marketing to us the things that are most profitable to them. And those are the things that are packaged and processed and what-have-you. That means you have the simple thing of the explosion of obesity and hunger as a result of capitalism in our food system.
