<P> 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 . </P>
