A system based on perpetual growth has reached the limits of that growth and is now actively and manifestly shredding the planetary ecosystem., This isn't a question of anything other than the survival of human civilization. Your political views are irrelevant. The system is at its terminal point. In some other timeline we reformed the postmodern capitalist system and regulated it to prevent ecocide. That is not this timeline. That's because, concurrent to the shredding of the ecosystem, the culture of end stage capitalism, a culture evolved to make us all obedient consumer-workers, has further evolved to make us delusional, psychotic, fascist, it has shredded the collective unconsciousness of humanity and resurrected fascism as a way to defend the system as it self-destructs.
