This reference resource, in atlas format, is an online-only compendium of maps and data sets accompanied by multimedia elements designed to illustrate key concepts in green issues and environmentalism graphically and interactively. Topics for the maps presented in this work were selected from articles in the 12-volume SAGE Reference Series on Green Society: Toward a Sustainable Future. Each map includes links to one or more of the series articles. Maps include interactive components, with clickable icons to deliver the data and statistics that make up each map. Further, multimedia elements (photos, video and audio clips and transcripts) accompany map themes and presentations.
