"Ecologists would do well to read this book, examine its case studies, and seriously consider their implications for ecological research and assessment."-- Glenn Suter, U.S. Environmental Protection Agency"…This volume, uniquely in my experience, brings together a conceptual framework for combining economic valuation and ecological risk assessment…provides some context for the whole effort within the institutional realities of American environmental management agencies."-- Alan Randall, Department of Agriculture, Environment, and Development Economics, The Ohio State University
