This article from Ecogeek offers an introduction to green roofs, and shares pictures of some existing green roofs and some ambitious projects in the works.
"It's not just for hobbits anymore. The logic of green roofs is becoming more apparent. We can minimize our bills while maximizing the beauty of the urban landscape. And every day it's becoming a little easier to live in a house that just happens to have plants growing on it."
"Green roofs keep the roof cooler, which helps to reduce the heat-island effect, which contributes to cities being hotter than the surrounding countryside. This can be beneficial to the building in reducing its summertime cooling load."
"A green roof is also a source of oxygen and provides a habitat for some birds. Birds and insects can find homes much more readily in the living environment of a green roof, where an ordinary roof is nearly barren. And yes, it's even possible to graze goats."
