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.

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.

By the end of the 1960s, the United States owned more than half of the Indian rupee money supply, and that had been acquired through food aid. So I think it's very interesting to see the very long history of how sovereignty and food go together. When some countries remove another country's ability to feed itself, it is a very powerful tool. Imperialist countries, like the United Kingdom, like the United States, have used it for centuries.

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.

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 food shortages and high prices have certainly sparked the world media's attention, particularly since they're coming in such diverse places, being everywhere from Haiti, to Senegal, to Bangladesh, to Egypt - a range of countries. That sort of caught the media off guard, and serves the media's prurient interests insofar as "it bleeds, and so it leads".

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.
