UBI, consumerism, and sustainability / human survival

I don't know much about economics, and I'd be really keen to query the WSO hive-mind about this.

It appears that the our consumerist system is not terribly conducive towards building a sustainable future for our species. Having companies run around and produce hard goods in an endless drive to generate profit is highly environmentally destructive.
There just can't be this endless drive to consume, to own more stuff, etc. We're just not going to make it as a species if that's the model. We need to be thinking instead about how we reduce our carbon load, get renewable energy, get clean water sustainably, get food sustainably, and survive as a species even as our population grows.

I'd be keen to learn more from the closet economists in the group, since I only had a few econ classes, and they were just the basic micro and macro econ.

And I'm not advocating for anything here other than our survival. I'm not saying "capitalism bad socialism good" or anything like that. I'm just a finance guy, and a recent dad, wondering if our kids will have a habitable planet to live on, and how policy and economics might be able to chart a sustainable future.
