Does sustainability have anything to do with saving the earth?

I mean it is supposedly all about sustaining this planet. But I just wonder. I think sustainability is about the feeling that you are doing something to save the earth.

I know that’s why the projects we’re working on have a green certification. I suspect deep down inside the powers that be don’t give a flying bleep about saving the earth. But they do know their future tenants like the idea of living in a place that supposedly was built according to ways that may have helped prevent some harm planet.

So now, its not about doing anything per se, but checking that box.
