"In nature there is no waste. Every waste product becomes a benefit for another event - and that's what we try to do here." says Myles Harston, of AquaRanch Industries, who has been working with aquaponics 1992.
In an aquaponic system, the people feed the fish, the fish waste feeds the plants and the plant roots clean up the water for the fish.
They grow tilapia and a wide variety of organic vegetables including lettuce, kale, chard, herbs, tomatoes, and hot peppers. These crops grow without soil -- in effect, on top of the fish tanks.
According to Mr. Harston, the average salmon farm discards enough fish waste, which is raw sewage, into the environment to correspond to the sewage levels of a town of 65,000 people. Here, it is instead re-purposed as a valuable commodity.
"If I do anything to the fish it'll affect the plants and if I do anything to the plants - it'll affect the fish."
Together, they produce healthy organic food indoors, without soil, without generating waste.
