@neddie And I'm pointing what has to happen if we *actually* want to have a shot of doing so, rather than just wringing our hands doing nothing because the absolute best case scenario is an impractical fantasy. Hence my use of the "right wing" term eco-fascism, ie the only political ideology that could successfully implement solutions on the level of "stop building all infrastructure" because you'll never get permission for that in a democracy.
You can tell people their lives have to change and win the argument, but if you expect to tell them their lives are doing to get a lot worse, now, immediately, in obvious and impactful ways in order to avert a crisis that still isn't "real" in a core-emotional way even for many of the people who believe it's happening and will be bad, then all you're doing is ignoring the political reality of the situation.
I'm by no means arguing for the status quo, we could be going *much* further than any of the mainstream UK parties are advocating, but taking the line you are is functionally a cry to do nothing at all. HS2 is a great example, in fact, the whole argument in microcosm - not a perfect solution, but one that could have had real benefits as part of a broader strategy, and we *told* fellow greens who opposed it on puritanical grounds that *in practice* they were enabling higher carbon alternatives, and what's happened? All the embodied carbon in the sections of line already built - most of which were the most cost and carbon intensive of the whole route - is now wasted; most of the "savings" from HS2 are being spent on new roadbuilding; most of the land that was purchased for the remainder of the route will be sold to volume housebuilder cronies of the Tory party to build car-centric developments; the Euston terminus will only be built on a reduced scale with private money meaning more massive carbon-intensive office blocks or luxury apartment buildings.
*slow clap* a great victory for the environment, to be sure.
