Forty years ago, nearly 30 tons of methyl isocyanate gas leaked from Union Carbide Corporation’s pesticide plant in Bhopal, India. The incident exposed more than 570,000 people to toxic chemicals and claimed more than 10,000 lives within three days. Since then, it’s estimated that there have been more than 22,000 additional deaths related to the disaster. Its effects continue in chronic illnesses, adverse reproductive outcomes and genetic damage among survivors in the community. And four decades on, victims and their relatives are still seeking justice. Host Marco Werman speaks with Mark Dummett of Amnesty International about the deadly legacy of the chemical disaster in Bhopal.
