Until we have better technology we have to scale down or reliance on unsustainable tech. The alternative is adverse degradation of our most sophisticated technology available - the biosphere.

Yeah, see, saying “let’s all stop doing this thing” where the thing has diffuse long term bad effects for everyone but short term benefits for the person that does it generally doesn’t work. People have been trying that for a long time. It has to be written into law, or the benefits (economic or otherwise) need to be tilted toward doing the right thing.

I think a large carbon tax is the only shot of getting everyone on track with reducing impact.

Yes. No disagreement here. We absolutely need to put it into law. Although, making such legislation happen doesn't seem to work either. But we need to make it so.
