Ever Heard of a Green Roof?

A green roof is one that has vegetation of some sort growing on it.  A new idea that has been spreading is the idea to grow food on the rooftops of buildings in cities.  Think about it…all of the space of the rooftops of New York City being turned into a series of gardens to supply food for the city.  This would localize food, diminish the need for huge un-ecological farms, and give people healthier options…right from their rooftop.  What are your ideas on this topic?  Do you love it or hate it?
