With a foreword by E.O. Wilson, this book brings together internationally known experts from the scientific, societal, and conservation policy areas who address policy responses to the problem of biodiversity loss: how to determine conservation priorities in a scientific fashion, how to weigh the long-term, often hidden value of conservation against the more immediate value of land development, the need for education in areas of rapid population growth, and how lack of knowledge about biodiversity can impede conservation efforts. United in their belief that conservation of biological diversity is a primary concern of humankind, the contributing authors address the full scope of global biodiversity and its decline - the threatened marine life and extinction of many mammals in the modern era in relation to global patterns of development, and the implications of biodiversity loss for human health, agricultural productivity, and the economy.
