Aldo Leopold’s Land Ethic presents a transformative approach to environmental ethics, advocating for the moral expansion of ethical considerations beyond human interests to include the entire ecological community. In this paper, I am trying to explore the relevance of Leopold’s philosophy in contemporary sustainability discourse, emphasising its role in bridging the divide between anthropocentrism and ecocentrism. By comprehensive perspectives from Deep Ecology, Ecofeminism, and global environmental policies such as the Paris Agreement and the United Nations’ Sustainable Development Goals (SDGs), this study highlights the growing necessity of adopting an eco-centric framework. The paper also examines how Leopold’s principles can inform modern environmental governance, climate policies, and biodiversity conservation strategies. Given the spreading threats of climate change and ecological degradation, this research underscores the urgent need for a paradigm shift toward sustainability, rooted in Leopold’s ethical vision.
