If anything serious happens in world affairs, like a little war, which interrupts for a couple of weeks the flow of fuel tankers reaching Australia, life as we know it will very quickly grind to a halt. Australia has less than 30 days supply of fuel and oil in the country. Farmers will unable to sow or harvest their crops. They will be unable to get their produce to market whether it be grain, livestock or fresh food. It is said that everything at some time in its life is moved by truck. Take a long look at Fig 3 below and calculate how long you can manage without your medicines at home and in the hospital and how long you can manage for food if there isn’t any in the supermarket. The freight trains will stop. The power stations that rely on coal will have to dig into their reserves and then what? No fuel for the coal trains. There is just three days supply of petrol in the petrol stations. When that runs out how do the kids get to school and how do the majority get to work?
