Wouldn't this be extremely dangerous if a form of "plastic rot" was created? Things like PVC sewer pipes, or any long-lived plastic parts in cars/equipment could now degrade over time, which could create huge costs to find alternative materials. After all plastic is pretty useful because it is biologically and chemically inert.
