What we need to get right is not focusing on the fear associated with quantity - not enough, scarcity, and lack - and moving instead to a worldview that explores quality and connectedness.

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.

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.

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.

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

If we cannot know what's possible, then we are free to do that which is pulling our hearts and that which is life serving.

much agricultural land which might be growing food is being used instead to 'grow' money (in the form of coffee, tea, etc.).
