I recently came across these rooftop farms which have sprouted up (pun intended) in several cities like New York City and Philadelphia. Brooklyn Grange Farms is a one-acre rooftop farm located in Queens, NYC that grows organic produce and sells it to local community and restaurants. They hope to inspire others to install rooftop gardens of their own and their goal is to "improve access to very good food, to connect the city more closely to farms and food production, and to make urban farming a viable enterprise and livelihood."Brooklyn Grange grows a wealth of different tomato varieties as well as salad greens, herbs, carrots, fennel, beets, radishes, and beans nine months out of the year.
Pretty neat, huh?! I only wonder why people didn't think to do this sooner.
