Answer:
A individual's ecological footprint is computed by adding all the requirements of people competing for biologically profitable space.
Explanation:
A individual's ecological footprint is computed by adding all the requirements of people competing for biologically profitable space, like cropland for growing potatoes or cotton, or forest for producing timber or sequestrating carbon dioxide emissions.
The Ecological Footprint uses core product yields (from farmland, woodland, pastureland, and fisheries) to measure the area needed to sustain a given operation.
