Here the essential function that the non-developed world fills for the industrialized communities is brought under critical discussion. (Editor/RK)

In wiping out the natural heritage over which we were given dominion and stewardship responsibilities, we are sowing the seeds of our own destruction. With the advent of the Reagan administration, the government's endangered species program has all but ceased to function. (RM)

This paper looks in detail at the "natural" causes of extinction as compared to the "technological" causes of extermination (abrupt niche-emptying), using examples of species that are both extinct and exterminated. Ways are suggested that can put a halt to extermination. (BT)

This paper is concerned with problems in assessing the behavior of trace substances introduced into natural systems, sampling models of five classes that might be used in the study of contaminants are reviewed. Adaptation of an industrial experimentation method and techniques used in economic geology to ecological sampling is recommended.…

Discusses environmental and biological aspects of arctic and alpine vegetations in the New World between the equator and the Arctic Ocean, considering their similarities, differences, and susceptibility to disturbance by man. (JR)

Discusses economic factors as the essential causes of world environment deterioration. Presents case for critical and prompt action in prevention of natural resource exhaustion and pollution, particularly by means of replacement level, population control, and consequent economic organization. (JM)

Summarizes information regarding the importance of water to biological systems, the total ecosystem and its interdependent parts. (CS)

Considers the interface of humans and seacoasts over time. Explains how coastal zones are formed and human attempts to defend against sea level changes. Charts the percentage of major world cities that also are ports. Postulates how the greenhouse effect could influence sea level, examining potential human responses to changes in coastal zones.…

Reacts to previous article in which Becvar and Becvar contend that ecosystemic model represents counter-cultural movement, turning point, in mental health field. Finds it sad that, to many helping professionals, ecosystemic approach is still considered revolutionary. Hopes that Becvar and Becvar's article will stimulate continued discussion of…

Argues that food webs are an efficient method through which to communicate the core idea of ecology--that all living things are interconnected. Assesses the challenges and solutions to using illustrated food webs. (Author/CCM)

Eco-Inquiry may be defined as a "whole science" curriculum that embeds hands-on science within thematic multi-dimensional learning experiences. Three modules for the upper elementary and middle grades focus on food webs, decomposition, and nutrient cycling. Each module lasts 4-7 weeks and may be used alone or in sequence. Student…

Ecology is the relationship between persons and their environment. A caring ecological relationship is dynamic, able to be affected by the internal environment of the person and by the people/animal/plant/object external environmental surround in which a person lives. This paper attempts to examine the nature of ecology and how to facilitate the…

The cities of the world are great engineering feats. From the earliest dwellings of man constructed out of the raw materials of the environment, man has used his ingenuity to work engineering wonders that improve the circumstances of human life. By engineering technological skills, human beings have altered the environment to suit varied…

Addressing the Seventh American Water Resources Conference, Washington, D. C., October, 1971, Anthony Wayne Smith, President, National Parks and Conservation Association, presents an expose on how rivers should be managed by methods which restores and preserve the natural life balances of the localities and regions through which they flow. The…
