Today's population cannot be sustained on the 'interest' generated by natural ecosystems, but is consuming its vast supply of natural capital -- especially deep, rich agricultural soils, 'fossil' groundwater, and biodiversity -- accumulated over centuries to eons. In some places soils, which are generated on a time scale of centimeters per century are disappearing at rates of centimeters per year. Some aquifers are being depleted at dozens of times their recharge rates, and we have embarked on the greatest extinction episode in 65 million years. -- Paul Ehrlich (Sept. 25, 1998)
