An opportunity exists to combine three sustainable or waste materials, and to deploy the resulting product in such a way that it: increases sustainable fish stocks; reduces surface ocean acidity; sequesters carbon; and cools the globe profitably, effectively, quickly, and by means closely matching how Nature has done this safely for millennia.
Sustainable Development can come from solutions that replace fossil fuel consumption with sustainable resources, or from solutions that address environmental threats. Some solutions do both. One such prospective solution combines natural and waste materials to form ultra-slow release, buoyant flakes that provide the essential nutrients necessary to make the nutrient deficient half of ocean surface waters productive. In food production terms, this is nearly the equivalent of having another Earth, such is the productivity of nutrient-rich waters. At the same time, the flakes deliver four other key benefits: the dark blue of the less-productive high seas is replaced with the milky-green hue of productive seas, thereby cooling the world by reflecting more solar energy back into space; chemicals released by the additional microscopic phytoplankton contribute to marine cloud brightening, thereby also increasing global albedo (reflectiveness) fairly
evenly and hence reducing diverse regional effects; the additional photosynthetic phytoplankton offset ocean acidification by converting the carbon dioxide dissolved in the ocean surface waters (carbonic acid) into neutral biomass and oxygen; and part of this biomass sequesters carbon in the cold ocean depths and sediments when it sinks, leaving the surface waters able to take up more atmospheric carbon dioxide.
