When it comes to environmental sustainability, William McDonough is nothing less than a hero for the planet. In this audio lecture, he discusses how he has designed eco-friendly buildings with unique properties, such as the ability to produce oxygen. He urges his audience of Stanford Graduate School of Business students to set goals not toward an efficient bottom line of doing the wrong thing less badly, but rather toward the effective top line of doing the right thing. https://ssir.org/podcasts/entry/william_mcdonough_-_environmental_sustainability_and_green_design
