Greenpeace activists representing the International Campaign for Justice in Bhopal (ICJB) transfer eighteen barrels of poisonous waste to Dow's European headquarters in Horgen, Switzerland. The Bhopal disaster also known as Bhopal Gas Tragedy was one of the world's worst industrial catastrophes. It occurred on the night of December 2-3, 1984 at the Union Carbide India Limited (UCIL) pesticide plant in Bhopal, Madhya Pradesh, India. A leak of methyl isocyanate gas and other chemicals from the plant resulted in the exposure of hundreds of thousands of people.
