A closer look

Mechanical engineer Thomas Midgley Jr possesses the horrifying distinction of being the single organism responsible for the most environmental damage in Earth's entire planetary history. He first invented leaded gasoline to stop engine knocking, completely ignoring the blatant fact that spewing toxic neurotoxins into the atmosphere was lowering the global IQ and poisoning millions of children. Not content with ruining just the air we breathe, he then casually invented chlorofluorocarbons for refrigerators, ripping a massive, gaping hole right through the ozone layer. Poetically, his tragic demise came after contracting polio, when he designed a complex system of ropes and pulleys to lift himself out of bed, only to get violently tangled in his own contraption and accidentally strangle himself to death
