A crosspost from the discussion forum at www.EcoEarth.info:
Take this quick test to calculate your demands on the planet. It only takes about 3 minutes and asks you about things like you diet, transportation, housing, etc. The calculations are based on UN data
http://www.earthday.net/footprint/index.asp
"Redefining Progress's Ecological Footprint Analysis measures the amount of renewable and non-renewable ecologically productive land area required to support the resource demands and absorb the wastes of a given population or specific activities.
From a sustainability perspective, when humanity's Footprint exceeds the amount of renewable biocapacity a draw down in natural capital is required and this is considered unsustainable. Global Footprint accounts over the last forty years indicate a twenty-five year growth trend beyond the amount of renewable biocapacity. In short, humanity's Ecological Footprint appears to have breached ecological limits and is thus unsustainable.
Ecological Footprint Analysis (EFA) also raises several important social equity concerns. When the total amount of ecologically productive land area included in EFA is divided by the human population, there are about 4.5 acres (1.89 hectares) available for each person."

By the way... I scored an eight.
