I definitely think the price of food is going up. We need to figure out ways to manage that in a sustainable way. We have to figure out ways of increasing wages so people can afford it. That means redistribution, and rich people don't like to hear that. This administration simply won't hear of it. But without it, I fear even more Americans will be going hungry in the future.

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.

Far from being a “luxury for the rich,” organic farming may turn out to be a necessity not just for the poor, but for everyone.

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.

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.

I think we do need to worry about a food shortage, but we also need to worry about the quality of the food. A lot of the stuff that's marketed to us tastes delicious because it fools our bodies. It fools our bodies into thinking that a particular mix of fat and salt and sugar is good for us. In fact, it isn't. That's why you're seeing in the United States life expectancies are declining, particularly in rural areas. You're seeing life expectancies falling in part because of diet.

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