As a part of Google’s Environment Day on April 25th, we invited architect, designer, thought leader, and author William McDonough to Google NYC for a talk on "Design as Optimism." Design is the first signal of human intention. We are all designers because we all have intentions. What if our intention is to do good and make the world better because we are here? William McDonough shares real world examples of materials, products, buildings, communities, and economies that were designed in the search for good.
