Atlas of the Biosphere
is our online resource targeted to high school students, university students and teachers. It contains maps with geographically explicit data broken down into four general categories: Humans, Land Use, Ecosystems, and Water Resources. You may download maps (at 1600x1200 pixel resolution) and/or data (as an ESRI ArcView grid). The Atlas also includes animated schematics that look at the various resource flows and pools that make up individual Earth systems.
