Green Roofs - Science Nation

The video discusses the concept of green roofs, which are roofs with living plants that offer various environmental benefits. Columbia University researchers, including climate scientist Stuart Gaffin and civil engineer Patricia Culligan, are studying these roofs. They find that green roofs can significantly reduce urban temperatures, manage stormwater runoff, and decrease pollution. The research also explores using waste materials to enhance green roof systems, potentially revolutionizing urban environments.
