Aquaponics systems utilize one gallon of water to produce a kilogram of leafy greens, compared to over 30 gallons in traditional farming, showcasing remarkable efficiency.

Perched at the Osaka Health Pavilion during Expo 2025, a translucent dome hums with life. Inside, tomatoes ripen above brackish water while pufferfish swim below, their waste feeding the plants that clean their home. This is "Inochi no Izumi," or "Source of Life," a 21-foot-high sphere that reimagines how cities might feed themselves. The dome's genius lies in its vertical arrangement. Four water compartments form the base: seawater, brackish water, and two freshwater tanks.
