Floating cities “to provide freedom for nature on land”
Fish farming would provide protein-rich food for the inhabitants of the cities, with the waste used to fertilise crops on floating farms.

Excerpt:
“The floating city runs on marine energy, where energy can be harnessed from the oceans, together with generating power from the sun with a photovoltaic system and wind turbines in the ocean to store power in the utility-scale energy storage for each floating building.
“The floating city has a sustainable floating farming system for farming fruit trees and vegetables, as well as a system for farming fish that requires no additional feeding as they tend to draw their nutrients directly from the ocean currents.
“The nitrates and nitrites from the fish manure get broken down by bacteria to make the food for the plants. The plants in return, use their roots to filter out all solid waste from the fish waste to generate clean water.
“Vermicomposting can be used for processing waste food from the city, feeding it into a wormery to produce fertilizer for growing crops continuously, to prevent food from going into the landfill and converting it into something useful instead.
“The flourishing of ecosystems requires us to work together with nature, animals and insects, environmentalists, designers and scientists, just like the whales that protect each other and nurture their young together.”
