In urban centers, cities with green walls and roofs offer improved health and well-being, renewable resources, reliable food supply, and relief to the environment.
D. Ackerman

“Landscape planners will have the opportunity to make sculptured roofscapes, so that cities appear to be verdant hills and valleys. Streets will become shady routes carved through the undergrowth. Roofs will become mountain tops. People will become ants.”
