Aquaponics: Are Fish the Future of Organic Farming?




Parcs Holman speaks with a rambling conviction about the mechanics and advantages of aquaponics. “It’s totally the future,” he says. “You’re growing hundreds of pounds of food a year for a fraction of the water and power.” Aquaponics, the growing of plants with roots submerged in water, is being touted by enthusiasts as the next frontier in urban agriculture.
