The repeated warnings voiced by the scientific community during the past few decades have begun to be confirmed by real events, which have been noted both by political leaders and by the informed public. Climate change, the persistent occurrence of frequent and intense meteorological events, and the recurring crises caused by limited access to resources all convincingly demonstrate that we are approaching the end of a developmental cycle based on a flawed model, which is placing in peril the survival of humanity on its single planet. The political world must now take into consideration the need for a developmental paradigm shift and develop an arsenal of new strategies and tools better adapted to the current state of affairs.
