This book is concerned with the paradox that humanity depends on biodiversity and landscape systems for its survival, yet, at the same time, the current burden of humanity's use of living resources places the existence of these natural systems at risk. The role of human values, technological society and social and political processes in the creation and solution of the paradox are explored in this volume, whose origins lie in an international discussion meeting held at the PennState Center for BioDiversity Research. Leading contributors to the fields of biodiversity conservation, ecology, economics, entomology, forestry, history, landscape management, philosophy and sociology draw from their unique disciplinary perspectives to consider the origins, bases and possible solutions to this pressing problem.
