Imagine an industry that runs out of raw materials. Companies go bust, workers are laid off, families suffer and associated organisations are thrown into turmoil. Eventually governments are forced to take drastic action. Welcome to global banking, brought to its knees by the interruption of its lifeblood - the flow of cash. In this case we seem to have been fortunate. In the nick of time, governments released reserves that should with luck get cash circulating again. But what if they hadn't been there? There are no reserves of fish, tropical hardwoods, fresh water or metals such as indium, so what are we going to do when supplies of these vital materials dry up? We live on a planet with finite resources -that's no surprise to anyone - so why do we have an economic system in which all that matters is growth (see page 40)? More growth means using more resources.
