In recent years the engagement between the environmental 'agenda' and mainstream political theory has become increasingly widespread and profound. Each has affected the other in palpable and important ways, and it makes increasing sense for political theorists in each camp to engage with one another. This book, first published in 2006, draws together the threads of this interconnecting enquiry in order to assess its status and meaning. Andrew Dobson and Robyn Eckersley have gathered together a team of renowned scholars to think through the challenge that political ecology presents to political theory. Looking at fourteen familiar political ideologies and concepts such as liberalism, conservatism, justice and democracy, the contributors question how they are reshaped, distorted or transformed from an environmental perspective. Lively, accessible and authoritative, this book will appeal to scholars and students alike.
