The 21st century faces a significant environmental crisis driven by the rapid advancement of science and technology. While modernization, and industrialization have enabled human progress, their unchecked and unethical application has led to severe ecological degradation.is. Issues such as pollution, global warming, climate change, and biodiversity loss stem largely from anthropogenic activities. Environmental sustainability has emerged as a critical framework to address these challenges by promoting ecological balance and conserving natural resources for future generation. The Bhagvad Gita, a revered ethical scripture of Hinduism, offers profound guidance for understanding the distinction between “what is” and “What ought to be”. Norwegian philosopher and ecologist Arne Naess, the founder of Ecosophy, proposed a philosophy combining ecological and ethical principles to address environmental concerns. Deeply influenced by the teachings of Bhagavad Gita, Naess incorporated principles like lokosangraha (welfare of the world), self-realization, and nature centric human attitude into his ecological philosophy. This paper explores how Naess adapted these principles into Ecosophy to foster environmental sustainability and proposes their relevance in addressing contemporary ecological crises.
