As global financial markets learn difficult lessons on the consequences of unregulated spending, a new report issued by the World Wildlife Fund (WWF) warns of the danger to future prosperity if the reckless over-consumption of the Earth's natural capital is left unchecked.
WWF's Living Planet Report 2008, produced with the Zoological Society of London (ZSL) and the Global Footprint Network (GFN), shows more than three quarters of the world's people now living in nations that are ecological debtors, where national consumption has outstripped their country's biological capacity. Presently, human demands on the world's natural capital measure nearly a third more than earth can sustain. In addition, global natural wealth and diversity continue to decline, and more and more countries are slipping into a state of permanent or seasonal water stress.
