This video is one of the most inspiring, clear-sighted and humane I have ever watched! 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 tireless proponent of absolute sustainability (with a deadpan sense of humor), he explains his philosophy of "cradle to cradle" design, which bridge the needs of ecology and economics. from youtube : link
