What we do in the book my daughter Anna and I wrote, Hope's Edge, is to give people a glimpse of food as a source of nourishment, health, and community, rather than a threat. That means reconnecting with food as it comes from the Earth and with those who produce food.

Recently, [Diana Wilson] went on a hunger strike to protest Dow Chemical's refusal to accept responsibility for a 1984 chemical disaster in Bhopal, India, caused by a company they now own, Union Carbide. In the past, Diane's hunger strikes had been lonely affairs, but this time friends and co-conspirators from around the country took turns joining her on her flatbed truck under the hot Texas sun, greeting Dow workers as they entered the plant.

What gave her [Diane Wilson] the courage? If you look at someone like Diane, it's easy to say, well I could never be like that. But we don't know. We do know that it's possible for a woman, who didn't grow up as a world changer, to find it in herself to take a stand.

A teacher told me this story some time ago: She asked her students to line up in order of how much power they thought they had relative to the others in the class, and they all fought to be last in line. They didn't want to acknowledge that they had personal power.

What has dawned on me is that focusing on the "finite planet" frame sends a message that we have gone as far as Nature can take us and therefore we need to give power to forces outside Nature.

After the journey around the world, writing Hope's Edge, I began to see that it is not possible to know what's possible - and therein lies our freedom.

What we see today is a world movement represented by the World Social Forum, involving all sorts of interactions across cultures, not to create some new "ism," but to learn as we walk and to create more democratic forms of social organization that re-embed economic life in community.
