Growing a Greener World

Aquaponics: Raising Fish And Plants Together (San

From small tabletop setups to huge commercial warehouse operations, we explore the practice of growing food and raising fish together... indoors. In Chicago, we spotlight a vacant factory where a farm now produces vegetables and fresh fish on the city's south side. Then meet two young California entrepreneurs whose aquaponics kits teach sustainability in one square foot of counter space, plus their desktop gardens that grow mushrooms in a carton of coffee grounds.
