The Field Museum that applies an ecosystems approach to ecological and anthropological research, conservation planning, and environmental action. This work is part of an effort to protect biological diversity in the Lake Calumet region of metropolitan Chicago. The need for an ecosystems approach to urban areas, particularly in relation to conservation efforts, is discussed. Reviewing the problems of alternative, non-systemic perspectives in both research and policy toward urban problems, the article describes how the efforts of Field Museum scientists and educators integrate interdisciplinary research into a conservation and information design process." /> The Field Museum that applies an ecosystems approach to ecological and anthropological research, conservation planning, and environmental action.
