Book excerpt: Containing an in-depth study of the emerging theory and core of ecological law, this book insightfully proposes a 'lens of ecological law' through which the disparity between current laws and ecological law can be assessed. The lens consists of three principles: ecocentrism, ecological primacy and ecological justice. These principles are used within the book to explore and analyse the challenges and opportunities related to the transition to ecological law and to examine three key mining case studies.
