I can perhaps start and try to answer that.
First I'll refer you to a recent study that was done by the National Round Table on the Environment and the Economy I guess maybe a year ago. They looked at that, and to my reading it's still a great country with as much opportunity as we have now but with different opportunities, and with fulfilling lifestyles but different lifestyles. It will mean changes. It will mean changes in the cars we drive, in the way we build our cities, and in the way we travel. It will make differences to our industries and the way they are driven, and it will make a difference to the fuels we use. All of that is quite possible without a drop of living standard, as Professor Sauchyn said, and there are estimates that this can be achieved with quite small annual reductions in GDP, smaller than the normal rounding error of any estimates of annual GDP increases.
