Bruce Kania developed floating islands to clean nutrients out of the pond on his Montana farm. Water for the pond comes from the hind end of a 60 mile long irrigation ditch, loaded with nitrogen and phosphorus.He thinks the islands may have a bigger future, helping clean polluted water as a cheaper substitute for artificial wetlands.
His next step? He hopes to work on floating islands to breathe life into the Gulf of Mexico dead zone, and to sequester carbon on a global scale. Who knows, there may be floating islands in our future. Tweet
