Communist ecology does not ignore the material limits of reality, that's a strawman. Advancing recycling, renewable materials, renewable energy sources, all of it requires more advanced technology, but can be done in a fashion that does not harm the environment. My point is that degrowth does not work, and actually works against the capabilities of advanced ecology. We need to advance onto socialism as quickly as possible so as to end overconsumption and overproduction, but we should not try to freeze where we are at.
I guess what I am trying to say is that advancement does not mean endless production, and large industry does not mean overproduction and overconsumption.
