This introductory text of general readings for environmental studies is specifically prepared for undergraduate college students although useful also as a reference book for graduate students and instructors and as an information resource for the general public. The book is problem oriented emphasizing the interaction and interdependence of man and his environment on the basis of a total environmental concept. Material is presented in the light of a human-centered environment with the emphasis on the quality of the environment as essential to the maintenance of the quality of life. Twelve chapters and seventy-seven sections cover most of the major environmental problems. Presented are facts and factors of the human environment, including the physical, biological, and social aspects, processes which lead to environmental crises, and methods of abatement and solutions. Up-to-date references of major importance to environmental studies are cited, a glossary of terms for the various disciplines is supplied, and numerous tables and figures are drawn.
