Collective behaviours dictated by evolutionary shaped biological core drivers can’t be changed without changing the underlying human animals. Maybe the survivors who pass though a population bottleneck will sustainably inherit different properties due to the founder effect, but that remains to be seen.

Meanwhile the overconsumption of the ensemble and that of the underlying individuals will continue, until it can’t. The carrying capacity plunges, after a delay due to inertia the resulting excess deaths bring back the population to the new carrying capacity level, way lower than the current level. There is nobody to blame, even those who do know yet continue, uncaring, since their numbers are too low to measurably change the outcome either way. They still be bastards, though.
