This comprehensive reader offers in-depth analyses of critical developments in environmental values, bringing together in one volume the most influential scholarship in the field. Each carefully selected contribution assesses some of the most pressing questions of our time, focusing on the relationship between human values, world views and preferences, and the natural world. As the first reader of its kind in a rapidly expanding multidisciplinary field, this text provides students with a valuable framework for understanding the intellectual progress and future development of the study of environmental values. The book clearly emphasizes that environmental values must be understood not only as economic, benefit-cost or 'willingness to pay' considerations, but also as normative principles that are fundamental to behaviour and management practices.
