- A The total geographic surface area of land that a given sovereign country physically occupies within its officially recognized international political borders and territorial waters combined under usual circumstances according to most researchers
- B The amount of biologically productive land and water required to produce all the resources consumed and to absorb all the waste generated by an individual, city, or country; used to compare resource demand with Earth's biocapacity
- C The cumulative physical impact that seasonal large-mammal migration patterns have on overall vegetation cover within a clearly defined natural ecosystem boundary each calendar year in the majority of cases studied as widely reported
- D A direct numerical measure of the overall annual rate of global biodiversity loss occurring specifically within a particular geographic region or sovereign country in standard practice under most conditions encountered as frequently observed in practice
Correct answer: B. The amount of biologically productive land and water required to produce all the resources consumed and to absorb all the waste generated by an individual, city, or country; used to compare resource demand with Earth's biocapacity
Explanation: Ecological footprint: total biologically productive area needed to support a population's lifestyle. If global footprint > Earth's biocapacity → 'overshoot' (currently using 1.7 Earths per year). High-income countries have much larger footprints. Reducing footprint: less meat consumption, renewable energy, public transport, reducing waste.
