I disagree that it must become unstable, especially on a time frame relevant to anyone currently alive. Perhaps certain resources could be sheparded more sustainably than they have been but I do not think we were previously heading towards a consequence worse than we are currently experiencing.

That argument applied to current administrative actions is like saying "we all die someday, therefore we should all commit suicide right now".
