A fertilizer bomb that kills hundreds in Oklahoma. Fuel-laden civil jets that kill 4000 in New York. A sanctions policy that kills one and a half million in Iraq. A trade policy that immiserates continents. You can make a bomb out of anything. The ones on paper hurt the most.

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.

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.

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.

The opposite of consumption is not thrift - it is generosity.

One of the most abused country on earth is Mexico. The marketing spills over the border, and people are persuaded to eat food that's bad for them, more in rich countries than in poor ones. I was traveling the world. What really struck me was the way we engage with food - how it's a global phenomenon - the world becoming more and more disconnected from it.

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.
