Impacts of resource hungry exploitative economies
“What is 120 times the size of London? The answer: the land or ecological footprint required to supply London’s needs.” — Herbert Giradet
Our ecological footprint exceeds the Earth’s capacity to regenerate. A number of useful indicators and frameworks have been developed to measure the ecological impact that humanity and its dominant economic system with its patterns of production, consumption and waste-disposal are having on the planet and its ecosystems. The measure and methodology for ecological footprinting translates the resource use and the generation of waste of a given population (eg: community, city, or nation) into the common denominator of bio-productive land per person, measured in Global Hectares (Gha), that are needed to provide these resources and absorb those wastes.
Much of the educational power of this tool is its capacity to compare between how much bio-productive land exists on the planet with how much bio-productive land would be needed to sustain current levels of consumption. In addition it also helps us to highlight the stark inequalities in ecological impact that exists between different countries.

Ecological Footprinting is basically an accounting tool that compares how much nature we have and how much nature we use. He are currently using about 50% more ecological resources than nature is regenerating naturally every year.
This point of spending more than is coming in every year — or living of the capital rather than the interest — was reached by humanity in the late-1960s. It is called Ecological Overshoot and every year since Earth Overshoot Day — the day when humanity as a whole has already used up the bio-productivity of Earth in that year — is a little earlier. Here is a little video (3:30 min.) to explain the concepts of ecological overshoot and footprint.
