Trickle Down Episode 15: Earth's Most Destructive Organism Part 1 (Sample)

Thomas Midgley Jr. invented two things that were used all over the world. Firstly, he invented leaded gasoline. This helped car engines operate more efficiently, but at the cost of spewing poisonous gas everywhere. The second invention is Chlorofluorocarbons or "CFCs." These substances, which were sold under the brand name Freon, had widespread applications in refrigerators and aerosols. But it was eventually discovered that these CFCs were eating away at the ozone layer in Earth’s atmosphere. Ozone depletion allows more UV radiation to reach the Earth's surface, which can lead to skin cancer, cataracts, and weakened immune systems. The fact that a single individual invented both leaded gasoline and CFCs led Environmental historian J. R. McNeill to say that Midgley "had more adverse impact on the atmosphere than any other single organism in Earth's history." Before Thomas Midgley died in 1944, he didn’t see himself as destructive. The scientific community showered him with praise and prizes and accolades during his lifetime. And he didn’t even have reason to think he was doing anything bad. Government regulators who were tasked with protecting the American public gave his inventions a pass. This story represents a complete failure of tech entrepreneurs to consider the adverse impacts that their inventions might have, a failure of the scientific community to check one of their own, and a failure of supposed protectors of the public interest to do their jobs. And all of these failures meant that the generation after Midgley was forced to clean up his mess.
