From Karnal to Coimbatore, genetically modified (GM) crops are becoming a matter of great concern for Indians worried about safety as well as loss of biodiversity. Various groups in Tamil Nadu, such as Pasumai Thayagam, an NGO supported by the PMK party, Church’s Auxiliary for Social Action (CASA) and Socio Education Trust, are protesting against GM crops. They have the support of Greenpeace India, Care Earth, Eco-Science Research Foundation, Tamil Nadu Farmers’ Technology Organisation, Erode District Organic Farmers’ Association and several others that have launched a week-long campaign for a Tamil Nadu free of GM crops.
