"People now know the price of everything but the true cost of nothing. Price is what a person pays. Cost is what a society pays, here, now, elsewhere, and into the future. A pesticide may sell for thirty-five dollars a gallon, but what does it cost society as it makes its way into wells, rivers, and bloodstreams? Just because markets do not address value, goodness, justice, and morals does not mean that such concerns can be safely ignored."
-Paul Hawken, Amory Lovins, L. Hunter Lovins "Natural Capitalism"
