ecological economists have proposed that we can put an end to the debate once and for all with a simple and elegant intervention: impose a cap on annual resource use and waste, and tighten that cap year-on-year until we are back within planetary boundaries.36 If green growthers really believe GDP will keep growing, for ever, despite rapid reductions in material use, then this shouldn’t worry them one bit. In fact, they should welcome such a move. It will give them a chance to prove to the world once and for all that they are right.
