And environmentalists warn that just as a company bound for bankruptcy plunging into the red or a borrower " maxing out" on credit cards must face the consequences, so must man.
The biggest problem relating to the over-consumption of resources is climate change, but its other effects include deforestation, falling agricultural yields and overfishing.
Overfishing is one of the most easily understood examples of the abuse of nature. Catching too many fish has left species that were once common, such as cod in the North Sea and bluefin tuna in the Mediterranean, struggling to survive.
Although it is possible to make ever-increasing catches for a while, eventually only small, juvenile fish are left, and stocks become unviable. Similarly, emissions of greenhouse gases are rising, exacerbated by the growth of China and India, but the climate is poised to wreak its revenge. Already polar ice caps are melting at a rate that is startling scientists, and examples of extreme weather, such as Hurricane Katrina, which devastated New Orleans in August last year, are being attributed to global climate change. In February, when he was Defence Secretary, John Reid revealed that British military planners were already preparing for conflicts arising from the scramble for resources in 20 to 30 years' time...
