Bitcoin is not sustainable even for providing for it's own security let alone from an environmental perspective. Bitcoin also gives the world very little in exchange for these massive externalized costs. It will eventually fail and the ethical loop-jumping that proponents espouse will become clear. But other blockchain platforms are the mirror opposite. They can provide sustainable security, provided without environmental degradation, along with utility that will radically change most sectors of the economy in a similar if not even a greater degree than the internet did.
