There's something truly wonderful about how green building is encouraging people to bring life--in all of its wonderful diversity--back into cities. From the New York Times:
Aeries are cropping up on America’s skylines, filled with the promise of juicy tomatoes, tiny Alpine strawberries and the heady perfume of basil and lavender. High above the noise and grime of urban streets, gardeners are raising fruits and vegetables. Some are simply finding the joys of backyard gardens several stories up, others are doing it for the environment and some because they know local food sells well.
City dwellers have long cultivated pots of tomatoes on top of their buildings. But farming in the sky is a fairly recent development in the green roof movement, in which owners have been encouraged to replace blacktop with plants, often just carpets of succulents, to cut down on storm runoff, insulate buildings and moderate urban heat.
