The Bhopal Disaster occurred in 1984 at a Union Carbide plant in Bhopal, India. Several gas leaks had occurred at the plant in previous years, exposing workers to toxic gases. On the night of December 2, 1984, a major leak released 30-45 tons of toxic methyl isocyanate gas into the air, impacting 500,000 to 600,000 people with numerous health issues. The gas leak caused immediate effects like coughing, eye irritation, and difficulty breathing. There were also arguments that negligence and lack of safety precautions by the plant owners contributed to the massive toxic gas release.
