Rob White's pioneering work in the establishment and growth of Green Criminology has been part of a paradigm shift for the field of criminology as it has moved to include crimes committed against the environment. For the first time, this book brings together a selection of White's essays that explore the theories, research approaches and concepts that have been instrumental to our understanding of environmental harm and eco-justice. The book provides an additional foundation for scholarship that goes beyond expression of opinion or immediate empirical finding; the emphasis is on systematic analysis and theoretically informed consideration of complex realities. It serves as a platform for further debate and discussion of Green Criminology's theories, perspectives, approaches and concepts and their application to specific sub-areas such as environmental law enforcement, wildlife trafficking, pollution, and climate change. Its aim is not to provide answers, but to stimulate further dedicated theoretical contemplation of environmental harms, threats to biodiversity and extinction of species. This is essential reading for all those engaged with Green Criminology, as well as Criminological Theory, Eco-Justice and Environment and Sustainability Studies.
