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.

The one thing that everyone knows about America is people will say, I know my rights. One of those rights is the right to organize. When workers do get together and organize and drive up their wages, they are much, much better off. I think this is one integral part of food policy. We can't talk about increasing the price of food without figuring out how working Americans are going to pay for that.

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.

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.

Agricultural sustainability doesn't depend on agritechnology. To believe it does is to put the emphasis on the wrong bit of 'agriculture.' What sustainability depends on isn't agri- so much as culture.

I do think we have a food problem. In 2006, which is the year for which we have the latest data, 35.5 million Americans were food insecure. That means there are 35.5 million Americans who are so hard up at some point during the year that they didn't know where their next meal was coming from. That's a lot of Americans. They don't get reported very much because there's nothing spectacular about people skipping a meal because they're poor. The media tends to ignore that, just as it ignores the sort of chronic food shortages elsewhere in the world.
