World3 — Limits to Growth

A macro-simulation inspired by Meadows et al. (1972). Five interacting sectors — population, industrial capital, food/agriculture, non-renewable resources, and pollution — evolve over a 200-year horizon. Tweak parameters to explore overshoot, collapse, or equilibrium scenarios.
