I'm neither an optimist nor a pessimist. I am a dyed-in-the-woo l possibilist! By this, I mean with an eco-mind, we see that everything's connected and change is the only constant.

On the one hand, our social nature is our greatest beauty - it means that we have natural empathy and sympathy. But our social nature also means that we may let ourselves be controlled by the judgments of others, precisely because we care so much about our status in community.

I understand, of course, that grain-fed meat is not the cause of the world hunger problem - and eating some of it doesn't directly take food out of the mouths of starving people - but it is, to me, a symbol and a symptom of the basic irrationality of a food system that's divorced from human needs. Therefore, using less meat can be an important way to take responsibility. Making conscious choices about what we eat, based on what the earth can sustain and what our bodies need, can help remind us that our whole society must begin to balance sustainable production with human need.

The spirit that I am advocating is reframing how we view the world, and shifting from the negativity of lack and "not enough" to the positive frame of aligning with Nature.

The real cause of hunger is the powerlessness of the poor to gain access to the resources they need to feed themselves.

The good life for me always meant connecting with those big, important issues that grown-ups get so excited about.

I get goose-bumps when you talk about Diane Wilson. Who knows where she found that courage? When she was a child, she would crawl under the bed when a stranger came to the house. But in 1989, she found out that her county in south Texas was ranked worst in the country for toxic waste. She wondered if the effluent, dumped into the waters where she and her family had shrimped for generations, might be responsible for the dwindling fish populations. And she suspected that her son's autism might be related to the pollution.
