Union Carbide established a pesticide plant in Bhopal, India in 1934. In 1984, a deadly gas leak at the plant exposed hundreds of thousands of people to toxic chemicals, killing over 3,800 people initially and harming many thousands more. The incident was one of the world's worst industrial disasters. Union Carbide executives responded by sending aid and experts to Bhopal, but the company was later fined and faced legal issues over the disaster, which continues to impact the region to this day.
