This new book, by one of the world's most distinguished ecologists, provides a review of the holistic or "big picture" principles of ecology. It is a timely presentation of the basic ecological principles that must be learned to protect the environment that provides our physiological necessities. "Ecology and Our Endangered Life-Support Systems" stresses the point of view that ecosystem theory provides a common denominator for people and nature, and that "goods and services" of both people and nature are coupled and must be considered together. Without healthy life-support systems (such as atmosphere, forests, and oceans) to support and buffer human industrial urban and agricultural activites, there cannot be a healthy economy or a high quality of life. Dr. Odum has prepared this book with the general reader and the specialist in mind. All those involved in environmental matters, and seeking a review of major ecological principles, will broaden their expertise by reading this volume.
