This book uses a transdisciplinary systems approach to examine how Earth’s human-caused ecological crisis arose and presents a new legal approach for overcoming it. Ecological Law and the Planetary Crisis first examines how the history of humanity’s social metabolism, along with the history of human inventions and ideas, led to the human-Earth dilemma we see today and explains why contemporary law is inadequate for confronting this dilemma. The book goes on to propose ecological law—law that maintains human activity within ecological limits such as planetary boundaries while ensuring social justice and equity—as an essential element of an urgently needed radical pathway of change toward a perpetual, mutually enhancing human-Earth relationship. Finally, it offers a systems-based analytical tool for organizing actions to promote the transition from environmental to ecological law. Increasing the visibility, clarity and development of ecological law, this book will be of great interest to students and scholars of ecological and environmental law and governance.
