Architect and designer William McDonough asks what our buildings and products would look like if designers took into account "all children, all species, for all time." A proponent of absolute sustainability, he explains his philosophy of "cradle to cradle" design, which bridges the needs of ecology and economics. He also talks about some of his work, including the world's largest green roof (at the Ford plant in Dearborn, Michigan), and the entire sustainable cities he's designing in China.
