I spent a couple years engaged in some pretty innocuous (and quite lib) green activism at my university. We did info workshops, replanting what unqualified bureaucrats decided should be torn up, showed up to demos, and just generally tried to get people to give a shit: I know, when grounded in those terms, good luck. All of this came out of either ours or the student pocket - and if you listened at this time, you could hear the beginnings of the liberal capitalist culture blob rising from the ground to replace, redact and just generally make life harder if you're doing anything that doesn't support whatever bullshit UN climate goals they started to parrot as a PR shield. We eventually got dissolved after about four years of people giving less of a shit, right as those 'sectors' of activism became co-opted and effectively a buffer for the institution's ailing rep and quality.

Did I/we do anything that mattered if that time? Almost certainly not. What was 'raising awareness' as a mode to those types of communities has infected most of the orgs that people who care go to. Those people who - wide-eyed undergrads and ex-hippies - get disillusioned or somehow brainwashed into thinking the delicate corp-speak take on greening up their workplaces is anything other than easing to allow companies and industries to launder their nagging indifference, to busy people with bullshit trotskyite-esque minutiae while the planet burns.

Move forward a couple years, as the "warnings" well-meaning scientists and activists have been heaped on society have become normalised and (almost) banal to hear the latest reporting of, it's a herculean fucking task to not go full doomer about the situation and the likely reactions, but it's immensely important. The species isn't going to get wiped out, sure, but that shouldn't be the only thing people can give a shit about.
