The climate crisis is not just a challenge—it's an opportunity to reimagine everything. From how we power our lives to how we grow our food, move, build, and connect with nature, this TEDxLausanne Countdown edition brings together visionary thinkers and doers to explore breakthrough ideas for a livable, regenerative future. As old systems reach their limits, we invite bold minds to help us design what comes next—resilient, fair, and profoundly human.
