eco-footprint, ecological footprint

Refers to measuring the level of natural resources and ecosystems used to sustain one’s current lifestyle and consumption patterns.  Put simply, it is a way to measure the amount of productive land, water resources, and sea area required to continuously regenerate the resources consumed by one. The way the eco-footprint is measured is through a comparison of human demand against the Earth’s natural capacity to regenerate the resources and ecosystems used; or how much of the Earth (or how many planet Earths) it would take to support humanity if everybody lived a particular lifestyle.

The concept and measurement of the eco-footprint was originally developed by Mathis Wagernackel.
