Natural gas is not as clean as it pretends. Natural gas which general emits from field agricultural soils and meansurement of methane and nitrousxid (N2O).Based on Robertson et al 2000 Carbon dioxide Methane nitrous oxide are three GHGS of major can concern that are emitted from agricultural soil and the most potent.
In this phenomenon is called green house emmission that is happen because offer produce CH4,N2O,CO2 and other gases that can make a hole in the atmosphere.
Human need to eat and of course that is important for our lives by eating produce by agricultural and there is most appropriate to increase in human population and in the worlds expecially in asia rice is number one needed.
Based on Chen et al 2007 Rice is the staple food for nearly 50 % of the world’s people mainly in Asia. Harvested rice fields in China , averaging 30 m ha from 2010 to 2013 accounted for 18,7% of the world total (FAOSTAT).
Argument
Our atmosphere consists of many gases as CO2 ,NO2, CH4, absorb long wave radition that is emmited from the earth’s surface ang globally agriculture accounted production more than 50% of anthropogenic CH4 and NO2 emmission respech.
Based on Chen et al 2014 Globally agriculture accounted for 505 and 60% of total anthropogenic CH4 and NO2 emmission respectively in 2005. GHG emmission from agriculture contribute substantially to atmospheric pollution in china and else where.Over uses N to produce rice it can to be dangerous in under ground N reaction with O2. It become N2O and N2O is also produce from rice . Increasing and offer input N are to be dangerouse environmrntal problems.
Based on (ju et al 2009) Large input of N fertiliter and low nitrogen use efficiency (NUE) are causing serius Environmental problems , based on ju et al 2009 Miao et al 2010 Since early 1980 Chinese agriculture has greatly within a limited land area due to large input of chemical fertilizer.
Conclusion
Natural gases is not clean because of the human over use chemical to produce the rice paddies . Natural gas which in general emits about half the CO2. If coal when burned fossile fuel. The NO2 and CH4 of coal overuse N to produce paddies. So we must cheks ourself and we must try to invention a new system to produce rice paddies that is not cause serious environmental problem.
