Detailed explanation-1: -The Ecological Footprint of a person is calculated by adding up all of people’s demands that compete for biologically productive space, such as cropland to grow potatoes or cotton, or forest to produce timber or to sequester carbon dioxide emissions.
Detailed explanation-2: -The Ecological Footprint tracks the use of productive surface areas. Typically these areas are: cropland, grazing land, fishing grounds, built-up land, forest area, and carbon demand on land.
Detailed explanation-3: -An ecological footprint is the area required to sustainably support a given population rather than the population that a given area can sustainably support. An ecological footprint is therefore the inverse of carrying capacity and provides a quantitative estimate of human carrying capacity.
