Picture 2-70
Thomas Midgley discovered the CFC Freon as a safe refrigerant to replace the highly toxic refrigerants such as ammonia in common use. This resulted in extensive damage to the Ozone Layer. His other famous idea was to add tetraethyl lead to gasoline to prevent “knocking” thus causing worldwide health issues and deaths from lead poisoning. He is considered to be the man that – “had more impact on the atmosphere than any other single organism in Earth’s history.”
