Which disaster was caused by a chemical leak at a pesticide plant in 1984?

The Bhopal Chemical Leak is the correct answer because it specifically refers to the catastrophic incident that occurred in Bhopal, India, in December 1984. This disaster was the result of a gas leak at the Union Carbide pesticide plant, which released methyl isocyanate (MIC) and other toxic chemicals into the surrounding environment. The event led to thousands of fatalities and long-term health issues for the local population, marking it as one of the worst industrial accidents in history.

In contrast, the Chernobyl Disaster involved a nuclear power plant explosion in 1986 in the Soviet Union, making it unrelated to chemical leaks. The Deepwater Horizon Oil Spill, which occurred in 2010, was an offshore oil drilling disaster that resulted in significant environmental damage but was unrelated to pesticide manufacturing. The Love Canal incident, which gained attention in the late 1970s, involved hazardous waste dumping but was not specifically a chemical leak from a pesticide plant. Thus, the Bhopal Chemical Leak stands out as the sole event tied to a chemical leak at a pesticide facility in the specified year.
