While there is no shortage of of books on the environment there are few introductory texts that outline the social theory that informs human geographical approaches to the interactions between ecology and society. Students arriving at university often lack the understanding of history, economics, politics, sociology and philosophy that contemporary human geography requires. Environments in a Changing World addresses this deficit, providing foundation knowledge in a form that is accessible to first year students and applied to the understanding of both contemporary environmental issues and the challenge of sustainability. Students are challenged to develop and defend their own ethical and political positions on sustainability and respond to the need for new forms of ecological citizenship.
