Mathematical model predicts the extinction of half of humanity by 2064

A potent re-evaluation of the "Limits to Growth" World3 model projects a staggering collapse in global population, with estimates suggesting half of humanity could vanish by 2064 under current "business as usual" trajectories. This updated analysis, rigorously recalibrating five decades of real-world data, extrapolates from 12,000 years of demographic history to warn that pervasive patterns of resource consumption and pollution are accelerating humanity towards a critical population overshoot and subsequent decline. The original 1972 World3 model from MIT warned of societal breakdown if exponential growth continued unchecked. Recent research, updating the model, found humanity alarmingly aligned with its "BAU2" scenario, pointing to severe industrial and population declines starting in the 2040s and culminating in the 2060s. This isn't mere academic speculation; it highlights the collision course between insatiable consumption and burgeoning population centers, exacerbated by climate change impacts already destabilizing agriculture and exacerbating resource scarcity. While the model isn't a precise prophecy, its consistency with historical data underscores the urgent need for a radical pivot towards sustainable development, circular economy principles, and robust climate mitigation. Policymakers and industry leaders, especially across G7 nations and emerging economies, face immense pressure to implement systemic changes—from energy transition mandates to global resource governance—to avert the worst outcomes. The next decade is critical for demonstrating decisive action.
