A demonstrator throws kerosene oil on an effigy depicting Dow Chemical Company, which now owns Union Carbide, to burn it during a protest to mark the 30th anniversary of Bhopal gas tragedy in Bhopal December 3, 2014. In the early hours of December 3, 1984, around 40 metric tonnes of toxic methyl isocyanate gas accidentally leaked from a pesticide factory owned by U.S. multinational Union Carbide Corp. and was carried by the wind into the surrounding slums. The government recorded 5,295 deaths. Activists estimate 25,000 people have died from illnesses in the years since. Many more, they said, are dealing with cancer, blindness, respiratory difficulties and immune and neurological disorders, but with no support.
