Zero Carbon Food is an ambitious new London-based venture by British entrepreneurs Richard Ballard and Steven Dring that brings agriculture to a previously unused space within the M25: WWII air raid shelters beneath the Northern Line. The tunnels, which do not share air with the Underground, allow 2.5 acres of produce to be grown hydroponically 33 meters beneath the city. Besides the benefits of hyper-local production, the hydroponic system uses 70 percent less water than traditional open-field farming. Additionally, the indoor system allows for year-round production with LED lights, reducing the need for imported goods.
