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.

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.

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 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.

Food sovereignty... is most of all characterized by it’s conversations around how to end hunger and poverty.

The one thing that everyone knows about America is people will say, I know my rights. One of those rights is the right to organize. When workers do get together and organize and drive up their wages, they are much, much better off. I think this is one integral part of food policy. We can't talk about increasing the price of food without figuring out how working Americans are going to pay for that.

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