If The engine is right about 2032, food system collapse is likely the mechanism through which most people experience it. Four companies (Archer Daniels Midland, Bunge, Cargill, Louis Dreyfus) control 70-90% of global grain trading. Fertilizer depends on Russian/Belarusian potash (40% global supply) and natural gas (Haber-Bosch process). The Iran war is already cascading into European fertilizer crisis (Euronews, Mar 30) and African food supply disruption (AP: 'Africa is hurting from a crisis it had no part in starting'). Simultaneous breadbasket failure probability rises with warming: 54% corn failure probability at 2°C. Most cities hold 5-7 days of food inventory. The engine mentions food in passing under BAU2 and climate but never tracks the food system as an independent variable with its own chokepoints, oligopoly structure, and failure modes. Falsification: if food prices decouple from energy prices (i.e., food inflation runs ahead of energy inflation), the food system has its own independent fragility beyond the energy cascade the engine currently models.
