As international supply chains are optimsed and rely on routes and chains served by just-in-time deliveries, broken chains cause cascading interruptions across the net. The result is rising prices and productions coming to a halt at unforseen places. The breakdown of industrial civilisation won't come by natural disasters or environmental threats, but by the breakdown of supply chains that are too optimised to be resilient.
@simsa04 In the late 1980s, 1990s, and early 2000s, some business leaders warned about possible consequences of tightly-coupled just-in-time supply chains. But the idea of carrying inventories (equals increased investment) fell out of favor.
