The goals of the Caltech Population Program are to increase understanding of the interrelationships between population growth and socioeconomic and cultural patterns throughout the world and to communicate this understanding. This series of occasional papers is one step in the process of communicating research results. The papers deal primarily…

This key to freshwater and anadromous fishes of California is included as the fifth of a series of guides being produced by Project MER (Marine Ecology Research). This project is part of the effort to improve environmental education in the San Francisco Bay Area schools by gathering and organizing data on the ecological character of the San…

Discusses the origin, structure, and content of the first World Climate Conference in Geneva, Switzerland. The purpose of this gathering of experts is to assess and integrate current knowledge of climate with knowledge from other disciplines which, in combination with climate, affect human activities and the environment.

The need for cooperation among countries to control sulfur pollutants is stressed. (Author/MA)

Discusses the importance of microorganisms in chemical pollution and pollution abatement. Selected chemical pollutants are chosen to illustrate that microorganisms synthesize hazardous substances from reasonably innocuous precursors, while others act as excellent environmental decontaminating agents by removing undesirable natural and synthetic…

Discusses some of the problems associated with solid waste disposal and the recovery and recycling of valuable resources found in materials that are discarded as waste. (JR)

Discusses a wide range of topics related to the environmental crisis with particular emphasis on consequences for Australia. Suggests that Australian science teachers have both the opportunity and responsibility to play an active role in environmental education. (JR)

Offers a contemporary analysis of the interaction of man and the rest of the biota. Suggests that the dependence of man on nature is, more than the crisis of energy and world economics, the emergent scientific and political issue of the next years. (JR)

Discusses some of the processes involved in resource recovery (recycling) from municipal solid wastes. Provides specific examples of recovery of valuable resources, and suggests that the environmental consequences and technology related to solid waste treatment should be included in high school science courses. (JR)

The National Wildlife Federation's Fifth Environmental Quality (EQ) Index reports a continuing downward trend in the battle against environmental deterioration. All EQ indicators, except air, are lower than the previous year. Also discusses the political factors which tend to inhibit the progress of environmental and conservation efforts. (JR)

Discusses Commoner's ideas on the social value of the petrochemical industry and his suggestions for curtailment or elimination of its productive operation to produce a higher environmental quality for mankind at a relatively low loss in social benefit. (CC)
