Increase of CO2 and NOx Promote CO2 Assimilation, CO2 Fix and Food Production

Abstract

Since the industrial revolution, burning of fossil increased. Production of CO2 and NOx increased greatly. Increased CO2 and NOx promoted the CO2 assimilation. Production of grain and fish increased. About 360 billion tone CO2 is produced by burning of much fossil. About 14.4 billion tone NOx is produced in 2015. Most of emitted CO2 is fixed by CO2 assimilation. Developed country like USA, Japan, Germany, UK, France and Italy started NOx elimination and NP elimination at around 1980, 6 billion tone NOx is eliminated. NOx is main nitrogen fertilizer. NP in waste water is main nitrogen, phosphorous fertilizer. Therefore CO2 assimilation, CO2 fix plant growth is retarded and emitted 360 billion tone CO2 is not fixed completely. Concentration of CO2 increased about 2 ppm. In 2016, 142 billion tone CO2 is remaining to give global warming. We must promote CO2 assimilation by complete use of NOx and NP in waste water. Fossil fuel is burning out soon. We should not spend precious fossil fuel for the elimination of NOx and NP. We must increase CO2 assimilation as much as possible.
