Episode 28: Bhopal Gas Tragedy

The Bhopal gas tragedy began during the night of December 2–3, 1984, when methyl isocyanate escaped from the Union Carbide India Limited pesticide plant. The Bhopal disaster killed thousands in its immediate aftermath, exposed more than 500,000 people, and left a health and environmental crisis that still has no clean ending. CC and Kitty trace how a pesticide plant near densely populated neighborhoods came to store large quantities of MIC, the warnings raised before the leak, and the safeguards that were unavailable or ineffective as Tank 610 entered a runaway reaction. Water entered the tank, but the precise route—and Union Carbide’s later sabotage claim—remain disputed. The episode also follows the overwhelmed hospitals, contested casualty estimates, the 1989 settlement, the criminal cases, and the unfinished cleanup. In 2025, 337 metric tons of waste were incinerated, but residual material and broader site contamination remained unresolved into 2026.
