Global Warming can be Protected by Promotion of Plankton CO₂ Assimilation

Shoichiro Ozaki

The earth is warmed up by the heat evolved by the burning of fossil fuel releasing CO₂. CO₂ assimilation reaction is the reaction of CO₂ with water to produce carbohydrate absorbing heat. Burning reaction is reverse reaction of CO₂ assimilation. If we can compensate the generation of CO₂ and heart of burning with the absorption of CO₂ and heart by CO₂ assimilation, global warming can be protected. Plankton CO₂ assimilation reduced 95% CO₂ in Precambrian Eon to 400 ppm now in 35 billion years. It is said that 70% CO₂ assimilation is carried out at sea. Supply of nutrient N and P to sea is most important. Large amount of NOx is produced when fossil fuel is burned. This NOx should be released without elimination procedure as it is. Large amount of N and P is contained in drainage. The drainage should be released as it is. Deep sea water contain much nutrient N and P. Shallow sea water contain very little nutrient. Agitation of deep sea water with shallow sea water increases the plankton growth. These three points are effective methods to increase the plankton growth, to increase fish production and reduce CO₂ production and to protect earth warming.
