One of the greats of the blogging world, Mickey Kaus, warns that a factory explosion in Germany could bring the world’s automobile industry to its knees. The explosion in Germany killed two people, and knocked out a factory that makes Cyclododecatriene.Why should you care? Cyclododecatriene is a key ingredient in the chemical used to make a resin needed for a range of vital car parts like brake and fuel line coatings. Shortages could interrupt production at factories around the world. With the global economy so fragile, this is not a time that the automobile industry needs any trouble.Kaus points out that the factory would have been an ideal terrorism target, and the reality is that the world’s supply chains are much more vulnerable to a variety of interruptions than many of us fully grasp. Floods in Bangkok, tsunamis in Japan, political unrest in China, terrorism: there are lots of things out there that could disrupt the relatively free flows of people, goods and money that define our world today.
