Three major themes of ecology, ethics, and economics characterize the current conservation/environmental movement and present a challenge for the environmental educator in teaching about environmental quality. This bulletin provides assistance for the practitioner by identifying current instructional materials that address concerns in this area. The materials have been selected from those catalogued in the ERIC database since 1983 and are considered to be representative of existing available materials. Explanations of the selected instructional programs are provided and organized in 13 topic areas: population; world hunger and economics; air quality; water quality; water resources; wetlands; marine and aquatic education; hazardous wastes; energy education; wildlife; land use; urban environments; and decision-making, individual and institutional. A listing is included of teaching activity booklets which were published at the ERIC Clearinghouse for Science, Mathematics, and Environmental Education over the past 13 years. Two pages of references complete the document. (ML)
