'Many policy makers, especially those trained in economics, can describe the management of environmental systems as if we (humans) are best suited to be in the 'driver's seat', making all the decisions to assure our wellbeing is the sole consideration. They should all read the chapters in this volume! Extinction is an irreversible externality whose full impact is uncertain. By combining the insights of social and natural scientists, Dasgupta, Raven, and McIvor have assembled essays that will change this view. They are accessible, engaging, and important.' V. Kerry Smith, Emeritus Regents Professor, Arizona State University 'Partha Dasgupta, unexcelled among economists for his contributions to ecological economics, and Peter Raven, revered for his leadership in biodiversity science, have combined to assemble a collection of papers by a virtual who's who of experts on the subject of biodiversity loss and sustainability. This volume, the product of an obviously remarkable meeting at the Vatican, will be a touchstone for all those concerned with our declining biodiversity, and the implications for the future welfare of humanity.' Simon A. Levin, James S. McDonnell Distinguished University Professor in Ecology and Evolutionary Biology, Princeton University 'This volume provides an informative reference for policy makers and practitioners, offering new perspectives on biological extinction that adopt principles of social justice and sustainability.'
