The ecological footprint aggregates the area of cropland,forest,grazing land,fishing grounds and built up land needed to support a given population’s consumption and waste assimilation,using prevailing technology. It provides a tangible way to compare human demand with the Earth’s biocapacity. The stem describes exactly this estimation of required productive area,so ecological footprint is the correct term. Option A is therefore accurate.
Option A:
Ecological footprint analysis compares human demand for biologically productive area with available biocapacity,matching the stem’s definition.
Option B:
Carbon budget refers to allowable CO₂ emissions to meet a temperature goal; it is narrower than the land-and-water demand measure described.
Option C:
Biotic potential is a population biology term about maximum reproductive capacity,not resource-area demand.
Option D:
Demographic profile summarises population characteristics (age/sex etc.),not ecological resource demand.
