Footprint A

The first datascape above is the ecological footprint of one average American citizen. 1 It takes 8.2 hectares of land to provide everything an average American needs as well as absorb their waste. Of course, this land is not literally adjacent to the individual in question, rather, because everything we consume exceeds our local and in many cases our national boundaries the footprint is, in reality, distributed globally. But that, as the second datascape 'Footprint B' shows, is precisely the point.

1 Global Footprint Network, "National Footprint Accounts," http://www.footprintnetwork.org/resources/data/.php/GFN/page/footprint_data_and_results/ (accessed June 1st, 2016).
The Global Footprint Network defines a global hectare as "a biologically productive hectare with world average biological productivity for a given year. Global hectares are needed because different land types have different productivities."
NB There is a three-year delay in the process of calculating ecological footprints.
