Infrastructural changes always sound scary and impossible, and I am in no way saying one solution is the best or indeed going to work. But good questions maybe, which is why I am saying innovation is required. Changing our way of life is possible though, say when people switched to cars from carriages or when we switched to electricity and laid out the various grid systems. Asking people to move north is not going to cut it or be enough. When a technology is useful or practical or helpful, making the switch is easier.
