The video above is only a few minutes long, and definitely worth watching. It explains the affects of adding green spaces on roofs in NYC have as a sustainability effort. The most profound take away from the video is how beneficial it would be for the city, if all buildings were to add green spaces to their roofs. And while the green space will be good for the environment, it can also do double duty as a outdoor space for residents. New Yorkers can get the benefits of living in the city while enjoying a little bit of nature also.
