This 2007 book examines environmental law from a range of perspectives, emphasising the policy world from which environmental law is drawn and nourished. Those working within the discipline of environmental law need to engage with concepts and methods employed by disciplines other than law. The authors analyse the ways in which legal activities are supported and legitimated by work in traditional scientific or technical domains, as well as by certain more obscure but also influential cultural or philosophical assumptions. A range of regulatory techniques is explored in this book, through a close examination of both pollution control and land use. The highly complex nature of current environmental problems, demanding sophisticated and responsive legal controls, is illustrated by several in-depth case studies, including legal and policy analysis of the highly contested issues of genetically modified organisms and renewable energy projects.
