Deep Ecology is a worldview that stands apart from anthropocentric philosophies.
The well-being and flourishing of human and nonhuman Life on Earth have value in themselves (synonyms: intrinsic value, inherent value). These values are independent of the usefulness of the non-human world for human purposes.
Richness and diversity of life forms contribute to the realization of these values and are also values in themselves.
Humans have no right to reduce this richness and diversity except to satisfy vital needs.
The flourishing of human life and cultures is compatible with a substantial decrease of the human popuation. The flourishing of nonhuman life requires such a decrease.
Present human interference with the nonhuman world is excessive, and the situation is rapidly worsening.
Policies must therefore be changed. These policies affect the basic economic, technological, and ideological structures. The resulting state of affairs will be deeply different from the present.
The ideological change is mainly that of appreciating life equality (dwelling in stuations of inherent value) rather than adhering to an increasingly higher standard of living. There will be a profound awareness of the difference between big and great.
Those who subscribe to the foregoing points have an obligation directly or indirectly to try to implement the necessary changes.
