The report describes the environmental resource base, including ecozones, demographics, air, water, land, and wildlife; the stresses, including acid rain, dioxins and furans, wildlife and fish habitat, and environmental impact assessment; and a diagnosis for sustained use of air, water, land, special places and species, and energy. A glossary is included.
