Yeah and all the communist states are super ecologically friendly, oh no you don’t belive they are communist do you? Handy.
But let’s imagine a perfectly communist society, are workers all able to heat their house? Able to travel freely? Enjoy hobbies? If you answered yes to these then your either going to need magic or energy.
You can’t just pretend capitalism is responsible for everything bad, unchecked consumption can happen in any system as can over production, ecological destruction, and all sorts of potential problems. I would love to transition to a decent type of communism but I’m not going to pretend it’ll fix the climate on its own.
