Ecotherapy is based on the idea that people are connected to and impacted by the natural environment. A growing body of research highlights the positive benefits of connecting with nature. Practices include a variety of nature-based methods of psychological and spiritual healing and well-being. Grounded in the idea that people are not separate from the rest of nature, but rather nurtured through healthy interaction with the Earth. This connection with the earth and its systems is the essence, or the very core of ecotherapy. "Many clinicians who practice ecotherapy believe that the earth has a self-righting capacity which operates through complex systems of integrated balance, and that if people can harmonize with these systems, they may experience improved mental health. Personal well-being and planetary well-being, as proposed in many tenets of ecotherapy, are not separate from each other. People’s lives are therefore seen as part of a greater system of interaction."
