Cameron Sinclair demonstrates how passionate designers and architects can respond to world housing crises. The motto of his group, Architecture for Humanity, is "Design like you give a damn." Using a litany of striking examples, he shows how AFH has helped find creative solutions to humanitarian crises all over the globe. Sinclair then outlines his TED Prize wish: to create a global open-source network that will let architects and communities share and build designs to house the world.
