The Sierra Club's Fourteenth Biennial Wilderness Conference was cosponsored by the National Audubon Society, with over 100 organizations participating. It was among the largest assemblies ever held of statesmen, scientists, lawyers, conservationists, and government and UN officials concerned with the preservation, protection, and restoration of natural areas and wildlife. This volume contains the major papers and statements from panel sessions. In coverage and comprehensiveness, it is nothing less than a compendium and handbook on protection and conservation of the Earth's natural areas.
