From Kenya to Columbia, from Iraq to Korea, in slums, in schools, in prisons and in theatres, every day, people gather at TEDx events around the world to hear the best ideas bubbling up in their communities. Today, you are part of a global conversation about our shared future. So what is this TEDx? TEDx is an initiative of the TED conference, a nonprofit devoted to ideas worth spreading. We grant free licences to allow TED-like events to spread globally. This event today is based on the TED conference format and ideals but is independently organised by your local community. So please make sure to thank the team of volunteers who worked so hard on today's event. It's their ideas, dedication and time that made it all possible. It's they who booked all the speakers and the views you will hear today are of course those of those speakers, not necessarily of TED. We hope their talks spark an exciting conversation among you. This is a day for curiosity and for scepticism, for openness and for critical thinking, for inspiration and for action. The more you enter into it, the more you will take out. And now, on with the show!
