Figure 8 2006 Environmental Performance Index (EPI) uses 16 indicators of
environmental health, air quality, water resources, biodiversity and habitat
quality, renewable natural resources, and sustainable energy resources to

stresses on human health. This map shows the scores by quintiles. (Data from
Yale Center for Environmental Law and Policy and the Center for International
Earth Science Information Network)
