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.

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.

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.

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.

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

Exporters monitor economic and political policies to the developing world, but the consequences of that have been to make developing countries far more sensitive to the constant fluctuations. Developing countries are not always allowed to support their farmers in the same way as the U.S. or Europe is. They're not allowed to have tariff barriers. They're forced, more or less, to shrink their social programs. The very poorest people have fewer and fewer entitlements. The consequence of this has been that there's been a chronic increase in the vulnerability of those economies to price shocks.
