THE CONCEPT of non-renewable resources is not difficult. The litres of gasoline we burned yesterday are gone. They are not resting and recuperating. They are not off somewhere pining for the fjords. They did not leave behind a clutch of little litres growing into adulthood. They were one-time opportunities that have now passed away.
