We're running out of land, so let's build on water: Rutger de Graaf at TEDxDelft

Rutger de Graaf is on a mission to make the world a more sustainable place by using creative, innovative, floating solutions to major problems such as flood risk, climate change and food scarcity. According to Rutger, one of the world's biggest challenges is urbanisation. All over the world, people are moving from rural areas to cities. Already a majority of people is living in cities, which are often vulnerable to flooding. The land shortage created by urbanisation, leads to shortage of resources such as food, fuel etc. One thing, Rutger says, the world has plenty of is water. Therefore his solution is to build cities on water. 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)
