The denigration of our planetary environment has reached a critical point — in the last 50 years there has been a 69% loss of biodiversity of animals, plants, birds, fish, insects, and forests, according to the World Wildlife Fund. This means that sustainability is no longer an option for humanity. One cannot be sustainable with a destroyed habitat. The only option left for us is regeneration. Regenerative Development is a holistic approach to development where the conditions for life are enhanced. Humans must re-vitalize, renew, and regenerate both community and planet to ensure not only our survival but the survival of all species. Nature’s well-being and human well-being are inextricably linked. Human ecology is as broken and despoiled as Nature’s is. Both must be renewed immediately and synergistically. The nature and scope of our crises, at the center of which is runaway climate change, leave humanity with no other choice. We must regenerate or perish.
