For me hope isn't wishful thinking or blind faith about the future. It's a stance toward life - one of curiosity and humility.

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.

Hope is not wishful thinking. It's not a temperament we're born with. It is a stance toward life that we can choose...not not. The real question for me, though, is whether m hope is effective, whether it produces or is just where I hide to ease my own pain.

We'll learn fear might not mean 'stop'; personally, I've come to believe fear usually means 'go.' It always means listen closely.

The good life is not about avoiding fear. Just the opposite.

Approaches to growing food that align with nature changed human relationships.

I think of Wangari Mathai in Kenya. If she started out saying she wanted to plant 20 million trees, she would have been laughed at. In fact, the foresters and the government did laugh at her. They said, "Villagers? Un-schooled villagers? Planting trees? No, no, no, it takes foresters." So she planted trees anyway.
