More than 50,000 people from all continents came in the end of March 2013 to Tunis to attend the World Social Forum (WSF). They discussed on a global scale the combined social, economic, ecological and political crises of capitalism and how to fight collectively against them. Tunis shows-after 12 years of its existence-the importance of the WSF. It is internationally the biggest framework for members of social and ecological movements and left activists.
