Detailed explanation-1: -Ecological footprints are calculations that show the productive area of Earth needed to support one person in a particular country. An ecological footprint estimates the land used for crops, grazing, forests products, and housing.

Detailed explanation-2: -The simplest way to define ecological footprint would be to call it the impact of human activities measured in terms of the area of biologically productive land and water required to produce the goods consumed and to assimilate the wastes generated.

Detailed explanation-3: -The ecological footprint is calculated in surface area (global hectares or number of planets) and measures the surface area necessary for the consumption of an individual, a population or an activity.

Detailed explanation-4: -It measures the ecological assets that a given population or product requires to produce the natural resources it consumes (including plant-based food and fiber products, livestock and fish products, timber and other forest products, space for urban infrastructure) and to absorb its waste, especially carbon emissions.
