A teacher told me this story some time ago: She asked her students to line up in order of how much power they thought they had relative to the others in the class, and they all fought to be last in line. They didn't want to acknowledge that they had personal power.

What is different and exciting is how much we have learned. We learned we were right that we don't need the chemical model of agriculture. We know so much more about the life of soil now and we understand how plants synergistically work together with microbes and animals to create healthy conditions.

Every time you take a step and walk with your fear, you'll never know the impact. But you can be certain somebody's watching, and that courage is contagious.

[Fear] means that we are human beings walking into the unknown, and that we are risking breaking with others for something we believe in.

Science is showing us that we are even more connected to each other than we ever realized.

This is the first generation to know that the choices we're making have ultimate consequences. It's a time when you either choose life or you choose death ... Going along with the current order means that you're choosing death.

I think that fear of embarrassment is the essence of the human challenge.
