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.

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 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.

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".

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.

We need to realize that these industrial methods of farming have gotten us used to cheap food. The corollary of cheap food is low wages. What we need to do in an era when the price of food is going up is pay better wages. A living wage is an absolutely integral part of a modern food system, because you can't expect people to eat properly and eat in a sustainable way if you pay them nothing. In fact, it's cheap food that subsidized the exploitation of American workers for a very long time, and that's always been an aim of cheap food.

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.
