@justforthelulz I'd also remind you that the freaking
World Wars, each of which killed tens of millions of people in the span of a few years (plus the Spanish Flu pandemic immediately after the first one, which killed even more people than the war had) barely put a dent in global world population even in the short term. (Ballparked at ~1.65
billion in 1900 and ~2.52 in 1950; a ten or fifty million off that didn't actually mean diddly squat for the species at large, however awful such mass dying was in human terms.) Hell the Second through unclear and still hotly debated dynamics up and triggered a baby boom in the belligerent countries afterwards...
Summa summarum even apocalyptic industrial wars of ferocity and destructiveness never seen before or since (on account of people figuring out that fighting more of such is Not Worth) are entirely useless as means of population control. THESE shenanigans here would be wholly irrelevant even compared to the background attrition caused by
traffic.
