Discusses evidence of water pollution by nitrogen and phosphorous from fertilizers. Concludes that restrictions should be on watershed, not state or national basis. 35 references. (AL)

Provides a broad overview of the major natural removal mechanisms that occur in the environment, including chemical transformations, biological degradation, and physical processes. (Author/BB)

Presents a model for the removal of ozone from air masses by vegetation. Compares simulation with Los Angeles data, and suggests needed research. (AL)

Describes a wilderness conference in which a petition calling for "protection of our common global environment" was written and later submitted to the United Nations. (LS)

Described are the values of a forest ecosystem in terms of its products and processes, and the dangers posed to such ecosystems by the pollution stresses of urbanizations and transportation. Included are options available to slow or stop forest destruction and degradation. (SL)

Presents a list of recommendations concerning global data collection and sharing which will enable a genuine interdisciplinary and transsectoral analysis of environmental pollutants and their effects in order to influence environmental management. (Experts attending the conference represented 13 countries.) (BR)

Letter from Commissioner of Education of HEW compliments "BioScience" in keeping people informed about pollution through scientific insights and describes a community education project in Maine concerning environmental education. (BR)

Argues that perfected technology, not neo-Ludite response, is necessary for solution of world food and resource problems. Although energy supply will ultimately limit available food, reactors can supply sufficient power for 15 billion population. (AL)

Discusses the relationship between population size and pollution, and suggests that the optimal population level toward which we should strive would be that level at which man is in balance with the biosphere in terms of pollution production and degradation, coupled with a harmless steady-state background pollution level. (JR)

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…

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)
