Greenpeace activists entered a GE (genetically engineered) maize field in Southern France and carved a giant crop circle with an X in the GE maize, marking the field as a contamination zone. The action was in response to a ruling by a French court in which Greenpeace France was ordered to take down maps from its Web site that showed the location of commercial GE maize fields in France. Greenpeace demands that the French Government fulfils its responsibility and publishes an official register of GE fields that is accessible to every citizen.
