In Requiem for Nature, John Terborgh examines current conservation strategies and considers the shortcomings of parks and protected areas both from ecological and institutional perspectives. He explains how seemingly pristine environments can gradually degrade, and describes the difficult social context-a debilitating combination of poverty, corruption, abuses of power, political instability, and a frenzied scramble for quick riches-in which tropical conservation must take place. He considers the significant challenges facing existing parks and examines problems inherent in alternative approaches, such as ecotourism, the exploitation of nontimber forest products, "sustainable use," and "sustainable development." Throughout, Terborgh argues that the greatest challenges of conservation are not scientific, but are social, economic, and political, and that success will require simultaneous progress on all fronts. He makes a compelling case that nature can be saved, but only if good science and strong institutions can be thoughtfully combined.
