Story: In the mid-1900s, leaded gasoline was ubiquitous, added to reduce engine knock. Oil companies knew lead was toxic but prioritized profits. Geochemist Clair Patterson, while researching Earth's age, discovered alarming lead contamination in the environment and humans. He realized it came from gasoline and sounded the alarm.

Twist: For decades, Patterson faced fierce opposition from powerful oil and chemical interests. They tried to bribe, discredit, and defund him. Undeterred, he gathered irrefutable proof by analyzing ancient ice cores from Greenland and Antarctica, showing pre-industrial ice was lead-free. His relentless 20-year crusade led to the U.S. banning leaded gasoline in the 1990s,a policy that spread worldwide. Patterson saved millions from lead poisoning, boosted global IQ levels, and proved one determined scientist could defeat corporate giants and change history. 🌬
