A recent review of different agricultural options for the future was conducted by a panel of experts. The scientists posed the question: How are we going to feed the world when there are nine billion people on it, as there will be by 2050? And the answer they came up with was industrial agriculture won't work and genetic engineering won't work and the solution is going to be sustainable, and going to ecological kinds of farming that are based on local environmental conditions that work with local ecosystems available to develop a richer kind of farming technology.

There are two novels that can transform a bookish 14-year-old's life: The Lord of the Rings and Atlas Shrugged. One is a childish daydream that can lead to an emotionally stunted, socially crippled adulthood ...in which large chunks of the day are spent inventing ways to make real life more like a fantasy novel. The other is a book about orcs.

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.

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.

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.

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 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".
