A recent thought experiment for the city of Seattle regarding green roofs. Consider the image above. Let us highlight the area we are looking at, a green roof off of 1st and Union in downtown Seattle, Washington. Now, the question I asked myself was, “Why would you settle for just a patch of green when you could have a system of living networks right outside your stoop?” Pushing the envelope further, “What if Seattle converted all the rooftops in the inner city into green roofs?”
