Some NY schools, such as Fieldston, grow greens on their rooftops, to keep kids in touch with nature. The city’s youngest food critic, 12-year-old David Fishman, cultivated his taste for arugula in this rarified atmosphere.
Roofcrops — a beautiful idea.

I remember our science project in 8th Grade where we had a 16 square foot plot of land and had to create a vegetable garden. Teams with the most vegetables by the end of an 8 week period won. Great way to get in touch with nature, and figure out how it all worked.
