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.

My children threw me a life line: "Return to your roots - food - and rewrite your first book, Diet for a Small Planet." I learned that if I could just show up, in this case, if I could just get myself out of bed, get to the computer in my tiny office at MIT, and start writing, help would start arriving.

We can choose who we bring into our lives. We can choose who will reinforce our risk taking.

Because we are living in a culture increasingly dominated by fear where many feel blocked.

I had the realization that hunger is not caused by scarcity of food, it is caused by the production system and an absence of democracy throughout the world.
