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.

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

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.

The current food crisis is an opportunity for companies to engage in agriculture or biotechnology.

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.

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.
