A discussion, with panelists representing different perspectives, facilitated to encourage full participation by everyone present. The field of inquiry dubbed environmental dynamics (ED) includes a broad range of interests, many with differing views of the ecological world. These include, for example, purely ecological studies involving the interactions of organisms and their natural environment, technical studies of the effects of human activities on the environment and different methods employed to limit or counteract those effects, big picture analysis of the human-influenced world and the direction it is headed, plus many others. Popular topics often associated with ED include: “environmental regulation,” “the ecocosm dilemma,” “the oil crisis,” “global warming,” “environmental limits [to growth],” etc. The roundtable will explore the relationships among these different topics, emphasizing the role of system dynamics. The goals will be to establish common ground, to create useful distinctions, and to help organize the ED endeavor.
