Plastic Bottle Greenhouse

"This year, Americans will drink more than 30 billion single-serving bottles of water. To raise awareness of the alarming problem of plastic waste, Jasmine Zimmerman created the Bottle House - an open-roofed greenhouse made from hundreds of recycled plastic bottles.
It’s an excellent example of recycle a harmful and overlooked material into one that will grow vegetation, and Jasmine plans to exhibit the greenhouse in empty lots, rooftops, parks, and vacant buildings to help spread the word."
