Ready for a Sunday binge of talks that will make your head spin? In this new playlist, twelve speakers take on our biggest issues: shifting global powers, the value of democracy, climate change, the nature of time, the future evolution of the human race. Some of these talks bring good news and some bring potential bad news — and all of them bring to mind new questions as they supply answers to old ones.

Watch the TED playlist, “The Big Picture,” which includes talks by Misha Glenny on global crime networks, Rory Stewart on why democracy matters, Stewart Brand on why we should think ten thousand years in the future and Juan Enriquez on how the next generation may be a different species »

TED playlists are collections of talks around a topic, built to illuminate ideas in context. A new playlist is added every week. We hope you enjoy this installment.
