Earth on course for eco 'crunch' The planet is headed for an ecological "credit crunch", according to a report issued by conservation groups. The document contends that our demands on natural resources overreach what the Earth can sustain by almost a third. The Living Planet Report is the work of WWF, the Zoological Society of London and the Global Footprint Network. It says that more than three quarters of the world's population lives in countries where consumption levels are outstripping environmental renewal. This makes them "ecological debtors", meaning that they are drawing - and often overdrawing - on the agricultural land, forests, seas and resources of other countries to sustain them. WWF's David Norman says the world will need two planets by 2030. The report concludes that the reckless consumption of "natural capital" is endangering the world's future prosperity, with clear economic impacts including high costs for food, water and energy....Talk about your spin. The enviro's are clearly using the "credit crisis" and the political fallout from same to horn in on the legislative goodies. Watch for more of this tactic in the near future.
