Figure 4 Ecological Debtors and Creditors. The ecological footprints of some
countries exceed their biocapacity, while others still have ecological reserves.
(Data from Global Footprint Network)


Data and Map Analysis



  1. List five countries, including the three largest, in which the ecological
    deficit is greater than 50% of biocapacity. (See Figure 1, pp. S10–S11, in
    Supplement 3 for names of countries and continents.)

  2. On which two continents does land with ecological reserves of more than
    50% of biocapacity occupy the largest percentage of total land area? Look
    at Figure 3 and for each of these two continents, list the highest human
    footprint value that you see on the map.
