Around midnight on Dec. 2, 1984, an accident at a Union Carbide pesticide plant in Bhopal, India, resulted in 45 tons of poisonous methyl isocyanate escaping from the facility. Thousands died within hours. More followed over subsequent months about 15,000 in all. In total, about half a million people were affected in some way. Many of those who survived suffered blindness, organ failure and other awful bodily malfunctions. A shockingly high number of children in the area have been born with all manner of birth defects. In 1989, Union Carbide paid out about half a billion dollars to victims, an amount the afflicted say is not nearly enough to deal with the decades-long consequences. Bhopal remains the worst industrial disaster ever.
