I have long been an advocate of the most heinous of incorrigible criminals being set to the task of building the Trans-Antarctic Bike Path. There would be no need for security since everyone would be free to escape whenever they liked. Lots of fresh air and open space which would be a big improvement over tiny repressive cells in prisons. It would be a Gulag with a purpose, our Australia. They would also be getting in on the ground floor of global warming. The benefits to the rest of humanity of the T-ABP would be inestimable. Or at least difficult to estimate.
