Description:	With many of the crucial variables that affect human ecology changing almost daily, any text dealing with the subject can rapidly become out of date. For this reason we have decided to revise Population, Resources, Environment in two years, rather than on a more conventional four or five year revision basis. The statistics have been updated throughout and substantial additions and revisions have been made in most sections. Entirely new sections have been added on many topics, including forest resources, net reproductive rates and zero population growth, the impact of population growth upon the environment, heavy metals pollution, ecocide in Indochina, and Thomas Malthus. The material dealing with energy, weather, pesticides, integrated control, the Green Revolution, novel foods, radiation hazards, air pollution, crowding, birth control, population policies, abortion, and other major topics have been considerably reworked or expanded. In response to requests for more thorough documentation, the annotated bibliographies have been greatly enlarged. The index for this edition has been done by Jeanne D. Kennedy, and reflects, we think, the touch of one of the top professionals in the field. In short, this edition is really a new book, based on the old. We hope that we have retained the flavor of the original while making the work more comprehensive and useful. We have tried to adhere to our philosophy as expressed in "About this Book" (p. 445) by clearly stating where we stand on various matters of controversy. Our apprehension about the course on which humanity is embarked has not lessened in the past two years; we hope the next two will bring changes that will permit a more cheerful prognosis.
