The vast, integrative field of ecosystem health explores the interrelations between human activity, social organization, natural systems, and human health. Ecosystem Health provides concepts, methods, and applications of principles in this fluid field. Numerous case studies exemplify how assessment of ecosystem health can be carried out, and how environmental problems at all levels, from local to global, may suggest the presence of a global distress syndrome. The focus of this book is on opportunities for the future. Advanced undergraduate and graduate students as well as environmental practitioners will find Ecosystem Health a helpful resource in understanding the important relationship between humans and the rest of nature and our dealings with the environment on all scales.
