Too little has been done and nothing is about to start for responsible action to avoid crises from climate change and the associated issues, with which there would be disastrous collapse coming to cities one after another. It will not be desirable to be stuck in any of the cities then, as important things run out without transportation being adequate. What happens with climate change will be worse than most people think. But it was never sustainable with cities and we could be sustainable enough for how people can always continue, growing things apart from everything and being independent from needing involvement or anything from any cities.
