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.

Little wonder that it can seem unthinkable to say "no, thanks" to the modern-day equivalent of our tribe - our fear-driven culture.

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.

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

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.

Fear doesn't have to stop us.

Nature has an incredible capacity for regeneration and growth, but we can't experience it if we stay fearful and focused on lack.
