Thesis. The WHO puts global suicides at more than 720,000 per year: one every 40 seconds, the third-leading cause of death among 15-29 year-olds, 73% in low-and-middle-income countries. The evidence base from 2024-2026 says the same thing: we already have 100 individual tactics whose joint effect, deployed at population scale, can plausibly cancel between 174,650 and 700,300 of those deaths per year. Most of them are not expensive. Several are net cost-savers. The bottleneck is sequencing and capital structure, not medical science. This paper ranks them highest-impact-lowest-effort first, mixing neurodiversity support and AI in mental-health care with the operator-locked "cures poverty AND cures death" flywheel.
