Abstract: The current ecological crisis of climate change, biodiversity loss, pollution and depletion of resources has shown that anthropocentric and growth-oriented systems of governance are insufficient. The article discusses the role of ecological ethics in changing public policy by rethinking human-nature relationships. The paper criticizes exploitative developmental paradigms and highlights the ethical foundation of sustainable governance through perspectives such as biocentrism, ecocentrism, deep ecology, ecofeminism, indigenous ecological worldviews. It continues to investigate the relevance of ecological ethics in climate policy, environmental justice, resource management, agriculture and biodiversity conservation. The paper contends that successful governance requires that public policy structures contain ecological responsibility, participation, justice and sustainability. Finally, it proposes a model of ecologically ethical governance based on interdependence, coexistence and long-term environmental sustainability.
