Have you heard about Aquaponics, quite a small chance that you have, but some scientists are predicting it will be the future of organic farming. Aquaponics is the growing of plants with roots submerged in water. The system depends on a network of tubes connecting a pond of fish with “rafts” that hold the plants. As the fish create waste, the water circulates to the rafts where tiny bacteria convert it into nutrient-rich plant feed. Small amount of electricity is also used. Humans have been cultivating plants in water since ancient times. The Hanging Gardens of Babylon are said to be an early aquaponic system, and the Aztecs did it in the Valley of Mexico.
Parcs Holman, a scientist perfecting the system says, ” it’s a very practical solution for hyper-efficient cultivation of food. We know it’s scalable, we’re just experimenting to see what works.”
