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.

For every $1 advertisers spend advertising something healthful like apples, they spend $500 advertising junk food.

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.

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.

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.

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.

We have the industrial agriculturalists who try and make an argument that big is beautiful. But if you do the math, and particularly if you factor in that the price of oil is going to go through the roof, and so the price of transportation is going to go through the roof - making it abundantly clear that it's out of whack. The efficiency arguments are already crumbling, particularly if you actually include the cost of food pollution that these industries cause. They are tremendously unsustainable and tremendously inefficient.
