I recently visited a friend, who asked me if I’d heard about the diesel shortage and how we only had 25 days of diesel left. Amazingly, I hadn’t, but I have been warning Unprepared readers about potential fuel shortages since February.

Of course, a diesel shortage would be disastrous, as diesel fuels our entire supply chain: from the tractors and machines used by farmers to the trucks that deliver goods to stores. If diesel disappeared, the industrial supply chain would collapse.
