Often cited as the world's worst industrial disaster, here's a brief description from the Bhopal Medical Appeal: "On the night of Dec. 2nd and 3rd, 1984, a Union Carbide plant in Bhopal, India, began leaking 27 tons of the deadly gas methyl isocyanate. None of the six safety systems designed to contain such a leak were operational, allowing the gas to spread throughout the city of Bhopal. Half a million people were exposed to the gas and 20,000 have died to date as a result of their exposure. More than 120,000 people still suffer from ailments caused by the accident and the subsequent pollution at the plant site. These ailments include blindness, extreme difficulty in breathing, and gynecological disorders. The site has never been properly cleaned up and it continues to poison the residents of Bhopal."
"In addition to the dead, hundreds of thousands were injured, and thousands more deal with lingering maladies," writes Kyeann Sayer at TreeHugger.com. "Children born years later face reproductive problems and physical malformations. The original settlement between Union Carbide and India did not quantify these effects, and current definitions of corporate liability do not include them. Victims continue to struggle for redress from the Indian government and Dow Chemical (who bought Union Carbide)."
