This book will appeal to anyone interested in environmental politics, environmental movements, and justice theory. The basic task of this book is to explore what, exactly, is meant by "justice" in definitions of environmental and ecological justice. It examines how the term is used in both self-described environmental justice movements and in theories of environmental and ecological justice. The central argumentis that a theory and practice of environmental justice necessarily includes distributive conceptions of justice, but must also embrace notions of justice based in recognition, capabilities, and participation. Throughout, the goal is the development of a broad, multi-faceted, yet integrated notion ofjustice that can be applied to both relations regarding environmental risks in human populations and relations between human communities and non-human nature.
