Even if the civilization were to collapse completely due to resource depletion, it will be significant, but not really crippling setback as far as the survival of human species go. In 79000 BC, the toba catastrophe knock the entire homo sapien species down to a few thousand breeding individuals. We survived that and prospered. We are still fundamentally the same species with the same survival instinct, guile and robustness. Fall of civilization will be a humanitarian dissenter of unimaginable magnitudes. But it will not be a species survival setback anywhere near that magnitude.
A death toll of a million would be a staggering humanitarian catastrophe. A death toll of a billion would be an unimaginable humanitarian catastrophe. BBut a humanitarian catastrophe is not a species survival catastrophe. Out of a total population of 6 billion, a death toll of even 5.9 billion will not begin to endanger the survival of our species. It take a death toll of 5.99999 billion to genuinely emperile our specie's survival.
