In the 21st century, environmental harm is an ever-present reality of our globalised world. Over the last 20 years, criminologists, working alongside a range of other disciplines from the social and physical sciences, have made great strides in their understanding of how different institutions in society - and criminal justice systems in particular - respond - or fail to respond - to the harm imposed on ecosystems and their human and non-human components. Such research has crystallised into the rapidly evolving field of green criminology. This pioneering volume, with contributions from leading experts along with young scholars, represents the state of the art in criminologists' pursuit of understanding in the environmental sphere while at the same time challenging academics, lawmakers and policy developers to explore new directions in the study of environmental harm.
