Green Roofs for Healthier Cities

A local delegation reports on a recent visit to Switzerland to study the covering of thousands of buildings with living roofs. The Swiss model of green roofs is lighter, cheaper and richer in biodiversity than many American counterparts. How can we learn to develop a sustainable, affordable model to better reap the benefits of green roofs?
