This handbook has been compiled to aid concerned individuals and ecology groups more adequately define their goals, initiate good programs, and take effective action. It examines the ways a group of working individuals can become involved in action programs for ecological change. Part 1 deals with organization, preliminary organizing, structuring, conflict resolution, funding, publicity, and central office location. Part 2 is concerned with action. This involves attitudes to develop in line with their direction of efforts, developing public awareness, criteria for choosing a project, areas of involvement, getting the message across, political action, and legal action. Information supplied in the appendix provides a sample constitution, an action-oriented bibliography, and resource lists of information sources for environmental education, endangered species of wildlife, biocides, and air, water, and noise pollution. Although the booklet is based primarily on college campus experiences, it may be useful for all types of ecology action groups. (BL)
