Environmental Conservation and Environmental Change

Chapter 1 introduces the content and structure of the book. It identifies the main characteristics of the Hotelling approach to conservation, and the nature of the conservation problems it can address. It summarizes the evidence for large-scale, systematic changes in biodiversity and ecological functioning across biomes. It identifies what elements of the biophysical system have and have not been conserved, how this differs from one society to the next, and what has been gained or lost in the process. Finally, the chapter also discusses the different ways in which the conservation problem has been analyzed by natural and social scientists.
