Hanna Joe is 17 and has been donating hydroponic kits to children's homes and teaching her peers about sustainable urban farming.
Many balconies in Singapore may be dressed up with ornamental plants and patio furniture, but at the Joe family's Orchard Road condominium, a high-tech farm blooms.
A brown tank is home to 11 tilapia fish, which produce waste that is used to fertilise vegetables such as basil and perilla.
