Inside the container are two large vats and a fish tank, which looks barely large enough to hold the dozens of tilapia squirming around inside. Upstairs, rows of tomatoes, peppers, lettuce and even flowers line the walls amidst the zen-like sounds of trickling water.
The fish and produce are all part of a symbiotic farming method called aquaponics, which takes wastewater from the fish and filters it to feed the plants above, before recirculating it back down to the fish. Not only does the system solve the problem of animal waste, but it uses about one tenth of the water required for traditional agriculture. It also has the potential to help both fish and vegetables grow bigger faster.
