In this datascape each nation's per capita biocapacity (green) and per capita ecological footprint (red) are superimposed upon one another to reveal the discrepancy (surplus or deficit) between the two.1 Where ecological footprints exceed biocapacity it means those nations draw resources from and distribute waste to regions beyond their own national territory. Where ecological footprints are within the biocapacity of the nation's territory it means that said nation is living within its means in terms of its national landscape.
