The good life may mean doing some things that do not feel comfortable. It may mean sitting long hours just with yourself as you begin to listen to your own questions. That was the reality for me when I was 27, and it was really terrifying.

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.

Nature is with us if we can learn how to align with it and not break the basic laws that generate life.

Many families participate in the Community Supported Agriculture movement, which allows a family to buy shares in a farmer's produce so that they know where their food is coming from, and they can take their families out and see the farm and meet the farmer. That movement has helped create a new culture around food.

We got hooked on grain-fed meat just as we got hooked on gas guzzling automobiles. Big cars made sense only when oil was cheap; grain-fed meat makes sense only because the true costs of producing it are not counted.

I like to think of power back in its Latin root, its meaning comes from posse - to be able.

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.
