What is meant by the "Ecological footprint"?​

The easiest approach to define environmental footprints would be to describe the impact of human activities in terms of the area of biologically productive earth, water and waste production.

Explanation:The Ecological Footprint quantifies the biologically productive land needed to meet the demands of nature: fruit and vegetables, meat, fish, wood, cotton and other fibres, as well as absorption of carbon dioxide from the burn of fossil fuel and the room for buildings and roads.
