"Humanity is living off its ecological credit card and can only do this by
liquidating the planet's ecological assets," said Dr. Mathis Wackernagel,
Executive Director of Global Footprint Network, "While this can be done
for a short while, overshoot ultimately leads to the depletion of
resources, such as the forests, oceans and agricultural land upon which
our economy depends."
