From Sathyu’s Introduction to Bhopal for Young People
About 50 years ago, a few large corporations pushed forward a claim that if farmers used synthetic chemicals as fertilizers they could increase food production, and if they used chemicals as pesticides they could protect their crops from being damaged by different insects. The fact is that these chemical corporations had been producing deadly gases and other chemicals for use in the world wars and once the war ended they had no market for these chemicals; so they began a war against insects who they called pests.
