This is a collection of papers which resulted from an assignment given in a seminar dealing with the topic Man and His Environment at Phoenix Union High School, Arizona. The interdisciplinary seminar focused on the relationships between man and his physical environment. Its purpose was to introduce the participants to the spectrum of environmental problems confronting people today, to focus on the basic principles and areas of knowledge which apply to each, to explore the resources which are available to solve the problems, and to make a first step toward integrating this material into courses at the high school level. The course dealt successively with ecology, cities, and people; and covered such areas as natural systems, energy sources, pollution, land use, social goals, urban renewal, housing, transportation, new towns, environmental health, and personal space needs. The course was aimed at increasing the participants' knowledge base as a precedent to implementation of this subject area in the high school classroom. (Author/PEB)
