We live in a deeply extractionist society that tends to believe earth is a miraculous entity that can heal itself no matter how much we abuse it or take out of it. These brainworms tend to permeate leftists as well. There will need to be an intense restructuring of society after we win that isn't simply based on class. Sea freight and trade should be kept to a necessity basis, commodity production has to end at this point, not for communist ideals but for the planet. Industrial animal agriculture and fishing need to end. But you can't restructure society without having control over the means of production. That being said I think some of the people who say it's not worth talking about until we cross that bridge are deluding themselves. Climate change is the biggest radicalizing point for people my age and younger from what I've seen, and just going "we'll achieve communism and then figure out how to stop emissions" isn't a particularly inspiring rallying cry.
