The famous environmentalist associated with the concept of "deep ecology" is Arne Naess. Naess introduced deep ecology in the 1970s as a philosophical approach emphasizing the inherent value of all living beings, regardless of their utility to humans. This movement advocates for a radical shift in human perception and interaction with the natural world. It criticizes anthropocentrism and promotes ecological sustainability, urging individuals to engage in actions that protect the environment. Deep ecology inspires a holistic view of nature and has influenced contemporary environmental movements and policies.
