Let's suppose that the climatists get their way and man-made production of carbon dioxide ceases in Australia.
In this green utopia, all of today's cars, trucks, tractors, trains, ships and planes are scrapped. All refineries, cement plants, steel works and carbon-fired power stations are silent. All cows, sheep, goats and pigs have been slaughtered and rabbits and kangaroos feed on the weed infested wheat fields. Carbon forests have smothered our grasslands and all Australians are either holding their breath or have emigrated to sane havens.
