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.

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.

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.

We kind of know that food is necessary to survive. But our ways of connecting with food have been, in many ways, taken over by capitalism - certainly taken over by the influence large corporations have on the way that we eat and the way that we think about food. That's why kids these days are more prepared to take nutritional advice from Ronald McDonald than they are from their parents or their teachers or from scientists. And particularly in urban areas, you'll see kids who honestly believe tomatoes come from the supermarket rather than from a plant.

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

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.

Generosity makes us happiest. We'll be happier people when we share, not when we impose, but when we learn from one another. Because when I'm connected to everyone I disappear... in being excellent you lose yourself. And when you're connected to everyone, that's the best thing that can happen.
