Almost all participants in the Mega Marcha were opposed to genetically modified corn being further introduced in Mexico. There was, however, a small group of farmers from the Chihuhua and Guanajuato provinces, driving a tractor with signs supporting genetically engineered corn. They even admitted that they had already illegally planted genetically engineered corn. Many suspected that the group was funded by industry. To dramatize their pro-genetically engineered stance, in a march with thousands opposed to genetically engineered corn, they set in flames their tractor. Undoubtedly, something that the other campesinos could not afford to do.
