Discusses seals in terms of their classification, ecological influences, their pelage, moult and thermoregulation, respiratory and vascular systems, predation and mortality. (JR)

Examines a variety of options and costs involved in the safe disposal of radioactive wastes from nuclear fission reactors. (JR)

Describes the techniques which form the basis of current commercial instrumentation for monitoring five major gaseous atmospheric pollutants (sulfur dioxide, oxides of nitrogen, oxidants, carbon monoxide, and hydrocarbons). (JR)

Describes a new system for the detection and measurement of sulfur dioxide using a coated piezoelectric crystal. The device is rugged, portable, inexpensive, and should lend itself easily to automation. (JR)

Article lists and explains the three groups that comprise the ecological family and which are designed to help children take a first step toward discovering the real meaning of ecology. (Author/RK)

Discusses a student project for the control of environmental pollution. (RK)

Students in a Ohio school project, by using an entire watershed as their laboratory, are exploring ways to ward off pollution. (DS)

Changing attitudes of man toward many animal species are viewed as one aspect in stabilizing ecosystems. This research study attempts to indicate a hierarchy among attitudes toward animals, particularly for the purpose of developing positive attitudes toward rare and endangered species. (BL)

Argues that soils, topography, and ecology are three factors that school planners must consider. (Author)

Focuses on the hither to divergent race/poverty movement and the ecology crusade and examines new relationships to see just where there is convergence between the two issues, where there is conflict, and where is still the traditional indifference. (RJ)

Discusses our natural and human resources and how they relate to the quality of American life. Calls for immediate action leading to the creation of new knowledge which will re-establish the balance between man and his environment. Emphasizes the urgency of the problem by reciting factual information and statements from authorities. (RR)

Presents an 11-point agenda for a new assertion of peoples' environmental rights. (MF)

Reviews environmental studies which show that national climatic fluctuations vary over a wide range. Solar radiation, earth temperatures, precipitation, atmospheric gases and suspended particulates are discussed in relation to urban and extraurban effects. Local weather modifications and attempts at climate control by man seem to have substantial…

Major consequences of present and additional environmental quantities of DDT pesticide are predictable by mathematical models of transport, accumulation and concentration mechanisms in the Wisconsin regional ecosystem. High solubility and stability produce increased DDT concentrations at high organism trophic levels within world biosphere…
