At the end of the climate summit in Marrakesh in December 2016, 20 activists from the Field Liberation Movement in Belgium planted a “permit to cut” in a field of GMO poplar trees belonging to the Flemish Institute of Biotechnology. The permit was given symbolically to the Flemish Minister responsible for climate policy. The Minister became infamous for her statement regarding forest management that “Trees have always had the function to be cut.” With this in mind, activists encouraged her to cut the field of GMO trees.
