    The idea of domination over nature has led to an unprecedented destruction of the very systems which support us. Ralph Metzner explores the history of this global pathology and shows that disciplines such as deep ecology and ecofeminism are creating a worldview in which the mind of humanity and the health of the Earth may be harmoniously intertwined.
