This unique study of social harm offers a systematic and critical discussion of the nature of environmental harm from an eco-justice perspective, challenging conventional criminological definitions of environmental harm. The book evaluates three interconnected justice-related approaches to environmental harm: environmental justice (humans), ecological justice (the environment) and species justice (non-human animals). It provides a critical assessment of environmental harm by interrogating key concepts and exploring how activists and social movements engage in the pursuit of justice. It concludes by describing the tensions between the different approaches and the importance of developing an eco-justice framework that to some extent can reconcile these differences. Using empirical evidence built on theoretical foundations with examples and illustrations from many national contexts, `Environmental harm' will be of interest to students and academics in criminology, sociology, law, geography, environmental studies, philosophy and social policy all over the world.
