�Sustainability�s original impulse�to transform how we live together on this planet�has splintered into a zoo of small-bore activities. Maurie Cohen masterfully organizes this menagerie of interpretations and approaches into an overarching framework that recovers the radical meaning of the challenge.�Paul Raskin, Tellus Institute�This book offers a very accessible introduction to science, policy and practice associated with the broad and complex topic of sustainability. It delineates many central concepts and lines of development with references to relevant events and actors. A particularly strength of the book is that it critically questions the reliability of some well-established assumptions and concepts for fostering a sustainability transition. Accordingly, the book will be very useful as an introduction to sustainability for interdisciplinary audiences.�Doris Fuchs, University of Münster
