  • private property rights and the pursuit of profit do not trump the needs of our communities and our planet.
  • the earth is alive and we are all interconnected, to nature and to each other. When we live from this new/old story, the world looks very different—and we can no longer accept business as usual.
  • in order to change this business as usual, we’ve got to change the story we have about who we are and how the world works. We act as though the earth were a dead ball of matter spinning through the cosmos and running like a machine and as though human beings were truly autonomous actors independent not only of the environment but of each other.
