"This book will be invaluable to all of us, to inform us and educate us about why marine conservation is such a pressing necessity in the 21st century, underpinning the health and wealth of ours and future generations." - Dan Laffoley, Senior Advisor, Marine Science and Conservation, IUCN's Global Marine and Polar Programme, and Marine Vice Chair, IUCN's World Commission on Protected Areas. "There has been a need for a major work in this field for a decade or more, and Roff and Zacharias have filled that gap. This book provides a rich, well-ordered and holistic vision of the marine environment, providing a critical framework and context for the development of marine conservation. It will be an invaluable tool for conservation practitioners and policy experts, lecturers and their students." - Mark D Spalding, Senior Marine Scientist, Global Marine Team, The Nature Conservancy and Conservation Science Group, University of Cambridge, UK. "Roff and Zacharias have taken on the Herculean task of compiling the science foundation needed for successful marine conservation and management, and the result is a rich and rewarding synopsis of the most pertinent themes in marine ecology, presented in a user-friendly manner that lends itself to rapid uptake by planners, managers, environmentalists, and students alike." - Tundi Agardy, Executive Director, Sound Seas.
