I think you're both right: the current global level of consumption not sustainable, or necessary. Everybody wants a healthy planet, almost nobody wants to volunteer to consume less. Regulation is needed, and it will mean we have to consume less. I realize that's not what anyone wants to hear. On top of that, I think we need social safety nets that prevent the burden from simply crushing the poor while the rich continue to over-consume. In the climate crisis we are trying to pay off generations worth of CO2 debt and we haven't even stopped digging the hole deeper yet.
