Interesting array of maps of GM bans and GM free zones available through the European Conference on GMO-free Regions, Biodiversity and Rural Development website . The events, itself, took place in April 2009 in Lucerne, Switzerland. More than 260 regions, over 4500 municipalities and other local entities and tens of thousands of farmers and food producers in Europe have declared themselves “GMO-free” expressing their commitment not to allow the use of genetically modified organisms in the agriculture and food in their territories. Since 2005, the movement of GMO Free Regions in Europe holds an annual meeting.
