We have tried throughout the book to state clearly where we stand on various matters of controversy. Our apprehension about the course of humanity expressed in Population, Resources, Environment and Human Ecology has deepened; if there is another edition of Ecoscience, we hope that events will then permit a more optimistic evaluation.

To save space, most of the footnotes contain only authors' names and the titles of publications (or, after the first citation of a work within a chapter, a partial title). The complete citations are given in alphabetical order by authors' names in either the Recommended for Further Reading list or the Additional References list at the end of each chapter.
