I knew about Bhopal, but I didn't know it was Union Carbide. Fun fact: Union Carbide ran the Oak Ridge enrichment site for the Manhattan project. They also created the largest American industrial disaster with the Hawk's Nest tunnel disaster. It killed over 700 miners from silicosis by ignoring safety practices. They were bought by Dow Chemicals in 2001. I guess Dow didn't like the competition in the "be a horrible chemical company" market.
