At the First International Spring Colloquium "Humanity under threat: Who is in charge of the future?", 38 specialists such as Noam Chomsky, Rigoberta Menchú and Tawakkol Karman, from 11 countries, met to analyze and project the future of humanity. The discussions addressed crucial issues in what ended up being a deep inquiry into humanity's responsibility in building and caring for the future. The book Threatened humanity brings together these reflections. The resulting texts cover all the topics addressed: how to think about the future, the challenges of the climate crisis, the challenges posed by inequality around the world, and within regions and countries, as well as the possibilities that democracies have to assume this context and become stronger. In an era where politics and democracy are questioned and citizen trust declines, governments face growing instability and a loss of real power. As democracy faces global scrutiny, the big problems plaguing humanity, whether economic, environmental or health, have their roots and solutions in the political sphere. Now, who will take the reins of the future? The work highlights the need to reflect on our relationship with modernity, with nature, and on how we have eroded fundamental values, such as solidarity and the rights that once promoted coexistence. This book explains the complexity of current challenges and the urgency of thinking about how to build the future we want.
