a measure of human demand on the earth's ecosystems
Ecological footprint The ecological footprint measures human demand on nature, i.e., the quantity of nature it takes to support people or an economy. It tracks this demand through an ecological accounting system. The accounts contrast the biologically productive area people use for their consumption to the biologically productive area available within a region or the world (biocapacity). In short, it is a measure of human impact on Earth's ecosystem and reveals the dependence of the human economy on natural capital.
