Participants form the Mayan word "MA OGM" (No Genetically Modified Organisms) during a protest at the pyramid of Chichen Itza in the Mexican state of Yucatan May 13, 2012. About 2,000 people, organised by Greenpeace, Mayan communities, beekeepers, entrepreneurs and other non-governmental organisations, staged protests simultaneously at eight archaeological sites to demand that the federal government ensure the Yucatan Peninsula remains a territory free of genetically modified food, according to organisers.
