Let's talk about sand: Denis Delestrac at TEDxBarcelona

Denis Delestrac made his debut in non-fiction filmmaking in 2001 and signed a number of hits including IMAX blockbuster "Mystery of the Nile" and "Pax Americana and the Weaponization of Space", his first feature documentary. His latest feature documentary, "Sand Wars" is an epic eco-thriller that takes the audience around the globe to unveil a new gold rush and a disturbing fact: we are running out of sand!

In his talk he explains us where sand comes from and where it ends up. Our perception is that the ressource sand will always be available for us but thanks to his investigations we realize that this is not true and that sooner or later we will be running out of sand - and consequently won´t have beaches anymore.

In the spirit of ideas worth spreading, TEDx is a program of local, self-organized events that bring people together to share a TED-like experience. At a TEDx event, TEDTalks video and live speakers combine to spark deep discussion and connection in a small group. These local, self-organized events are branded TEDx, where x = independently organized TED event. The TED Conference provides general guidance for the TEDx program, but individual TEDx events are self-organized.* (*Subject to certain rules and regulations)
