    • Mountain grassland and savanna
    • Mediterranean shrub
    • Desert
    • Tundra
    • Mangrove
    • Freshwater ecoregion
    • Marine ecoregion

The main map is labeled “Have We Overdrawn Our Account?” and also
shows pie charts on “Human Land Disturbance” depicting human
dominated, undisturbed, and partly disturbed percentages for each
continent. Vertical bar graphs show original, present and remaining
intact forest covers.


  • “Threats to Biodiversity” illustrates the degradation of biodiversity through commercial logging, fishing, pollution and invasive human-introduced species.
  • “Conservation and Research” describes the need to conserve “hot spots,” representative land, freshwater, and marine ecoregions that harbor biodiversity worldwide.

Other components:

  • Graphs on extinct and living species
  • Information about bird migrations
  • Special sections:
    • “Rapid extinctions, slow recoveries”
    • “Habitat Fragmentation”
    • “Medicinal Plants and Animals”
