Summarizes what is known about two major variables involved in certain types of chemical pollution that seem to be changing the structure of the Earth's atmosphere. Discusses the greenhouse effect and the ozone layer. (TW)

Presents a method of determining environmental improvement by calculating a ratio of the measurement of environmental quality before and after an improvement project. Applies the method for four case studies in South Wales. (TW)

Discusses some of the variables affecting environmental decision making. Addresses ecological, legislative, cultural, political, and economic forces that influence such processes. Urges more attention to the contextual basis of environmental decision making. (TW)

Argues that environmental policy and education are predominantly based on Western beliefs about nature rather than on native and indigenous sensitivities. Discusses Western conceptions of wilderness, alternative perceptions and conservation practices, the role of fires in the ecosystem, the priorities necessary for integrating alternative…

Discusses how biomass in the form of fuelwood, crop residues, and animal dung can be converted into fuels such as biogas and ethanol to replace or supplement fossil fuels. Argues for future decentralized, integrated biomass energy development. (TW)

Discusses the trend toward more "earth-as-a-system" approaches in research and teaching about global science. Uses the "greenhouse effect" as a prototypical global change problem that requires interdisciplinary problem-solving approaches. (TW)

Summarizes the blueprint for environmentally sound development, which was endorsed by the Governing Council of the United Nations Environment Program in June 1987. Includes recommendations on a World Food Bank, satellite communication costs, labelling toxic chemicals and pesticides, and water quantity and quality. (TW)

Reports on the status of environmental studies programs, as determined at a workshop held in conjunction with the 1986 annual conference of the North American Association for Environmental Education. Focuses on environmental studies program development since 1976. (TW)

Examines some of the traditional and new methods that have been devised to harness energy from the sun in the form of heat. Discusses some current research and developments underway which are lowering the costs of equipment and installation. (TW)

States that tidal power projects are feasible in a relatively limited number of locations around the world. Claims that together they could theoretically produce the energy equivalent to more than one million barrels of oil per year. (TW)

Responses of 9,957 Pennsylvanians to a statewide needs assessment questionnaire were examined to determine if there was a rural/urban difference in residualist beliefs about social welfare programs. Results demonstrated that rural respondents were clearly less supportive of specific welfare programs and less accepting of institutional remedies for…

Describes Ocean Thermal Energy Conservation (OTEC) as a method for exploiting the temperature difference between warm surface waters of the sea and its cold depths. Argues for full-scale demonstrations of the technique for producing energy for coastal regions. (TW)

Discussed are the costs of deriving energy from the earth's natural reserves of salt. Argues that, as fossil fuel supplies become more depleted in the future, the environmental advantages of salinity power may prove to warrant its exploitation. (TW)

Uses survey data from Texas and North Dakota to examine characteristics of farmers experiencing financial stress and to assess relative utility of adoption/diffusion, structural, and ecological frameworks for explaining levels of farm financial stress. Finds theoretical frameworks inadequate to explain differences in financial conditions.…

Discusses the Airborne Antarctic Ozone Experiment (1987) and the findings of the British Antarctic Survey (1985). Proposes two theories for the appearance of the hole in the ozone layer over Antarctica which appears each spring; air pollution and natural atmospheric shifts. Illustrates the mechanics of both. Supports worldwide chlorofluorocarbon…
