Deep ecology is an environmental philosophy that promotes the inherent worth of all living beings regardless of their instrumental utility to human needs, and the restructuring of modern human societies in accordance with such ideas.

Deep ecology argues that the natural world is a complex of relationships in which the existence of organisms is dependent on the existence of others within ecosystems. It argues that non-vital human interference with or destruction of the natural world poses a threat therefore not only to humans but to all organisms constituting the natural order.

Deep ecology’s core principle is the belief that the living environment as a whole should be respected and regarded as having certain basic moral and legal rights to live and flourish, independent of its instrumental benefits for human use.
