The Bhopal gas tragedy of 1984 was the worst industrial disaster in history. A leak of methyl isocyanate gas from a Union Carbide pesticide plant in Bhopal, India exposed over 500,000 people to toxic gases. Immediate effects included blindness, respiratory illness, and death for over 3,000 people. Long term health issues included chronic respiratory disease, birth defects, and higher cancer rates. The Indian government passed new laws to regulate hazardous industries and provide compensation. However, survivors continue seeking increased compensation and medical support over 35 years later.
