Although the TEL seems inexcusable, I'm not convinced that the second point about CFC's is fair. Yes, they destroy the ozone layer, but that wasn't known at the time Midgley invented them, and they replaced refrigerants that were corrosive and poisonous. I also question this line: "Beneficial ozone is not terrible abundant, however. If it were distributed evenly throughout the stratosphere, it would form a layer just 2 millimeters or so thick." How would evenly distributed ozone create a layer? Something seems wrong with the research here.
