Following the phenomenal success of the film Demain (Tomorrow), Cyril Dion looks back at the initiatives inspired by the documentary. He takes on board his friend Laure Noualhat, a renowned journalist on the ecological front who is highly sceptical about the ability of micro-initiatives to have a real impact on climate change. Their humorous confrontation pushes them to the limit: what works, what fails? And what if, in the end, all this forced us to invent a new narrative for humanity?
