The memes of the climate

I think this goes back to my original question, obviously capitalism has had it's disasters, that much is known, but at the same time you have disasters like Chernobyl, Kyshtym, Dzerzhinsk. I understand the USSR was not the ideal communist/socialist system, but it's the most apparent we have (going back to my original question, I think?). I just feel like statements in OP are not the right rallying call if actual change is desired, as it implies we just need to shift to our current implementations of other systems. I think the only real answer, like I mentioned in other comments is to bypass current systems and investigate new options.
