Harjant Singh, Hartej Singh, Amarjit Singh, Vinod Jyani and Rajneet Singh are "natural' farmers from the cotton belt of Punjab who were here in the Capital today to demand a complete ban on the Genetically Modified (GM) crops and foods in the country. They were among hundreds of farmers and consumers from 15 states of the country who gathered on "protesting pavement' of the Jantar Mantar saying they would not "become guinea pigs in experimentation in the name of GM food and crops', adding that the GM crops were certainly no answer for the country's food security.
