Containing an in-depth study of the emerging theory and core concepts 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. This thought-provoking book argues that ecological law should develop a needs-based approach to mining coupled with an ecological integrity standard in support of the effort to build a convivial and ecologically just society. This book's innovative approach treats ecological law as an emerging discipline by summarizing and discussing key aspects of its theory, including its foundations in science and critiques of economic growth; the core ideas from its foundational scholars; how to define it; and how it relates to Indigenous legal traditions and green legal theory. The Lens of Ecological Law will appeal to scholars and students in the fields of environmental and ecological law, sustainability and natural resources, whilst also being of interest to readers concerned with extractivism.
