The Circle of Life is more than the food web. It's a self-organizing system of global life-cooperation and energy dissipation. Its balance and stability have been taken for granted for millennia. But in the age of the climate crisis, the Circle is breaking down. From the 1960s onward, philosophers, artists and spiritual teachers promoted the idea of the 'Green Self' to help us understand how the Circle works, and how we harm ourselves when we damage it. But in all that time, the climate crisis only got worse. The Greening of the Self didn't happen. Using the science of ecology and a deep dive into human nature, this book explores what the Circle of Life really is, and what becomes of us when we face it in different ways. The exploration reveals a deeper eco-spiritual perspective, in which the Immensity of the Earth, and the breakdown of the Circle, are calls to action: to heal the Circle, and to create a better world.
