At the Anti-Spe-Days in the Hambach Forest, we were able to hold a workshop on international mobilization for a mass action in 2021. Numerous new networks on animal liberation and animal rights activists from Europe have emerged. As part of the workshop, plans were concretized how the mobilization can be carried out effectively and strategically. The workshop also provided a framework for exchanging views on transnational experiences with repression and the implementation of actions.
