Biotechnology congress 2019: The effect of increase of NOx and CO2 on grain and fish production, protection of global warming and climate

Shoichiro Ozaki

In order, to study the reason why global warming is happening. Studies were conducted on amounts of CO₂ emission, CO₂ concentration NOx emission, grain production, fish production, population and CO₂ fixed from 1900 to 2016. Since the industrial revolution, burning of fossil and 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 fossil fuels. About 14.4 billion tone NOx is produced in 2015. Most of emitted CO₂ is fixed by CO₂ assimilation. But since developed country started NOx elimination and NP elimination at around 1975, half of produced NOx is eliminated. Therefore, emitted 360 billion tons CO₂ is not fixed completely. Concentration of CO₂ increased about 2 ppm. In 2016, 142 billion tons CO2 is remaining to give global warming. 142 billion tons of CO₂ must be reduced. We must promote CO₂ assimilation by complete use of emitting 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.
