Explaination
-Greenhouse gases (GHGs) have different sources within agriculture. The livestock sector alone is responsible for about 44% of human-induced methane (CH4) emissions, 53% nitrous oxide (N2O) and 5% carbon dioxide (CO2). Methane has two main sources:
the digestive processes in cattle and similar fermentative processes in manure
rice paddies; where constant flooding of the fields creates similar, anaerobic conditions which favour methane production. Furthermore , the tractors used in farm fields contributes to the 5% of carbon dioxide emissions, this is due to it’s fuel which releases c02 into the atmosphere and causing heat to be trapped by the co2 which results in an enhanced greenhouse effect
Nitrous oxide is mainly formed during the application of fertilisers rich in nitrogen to fields. It also originates from manure or engines burning fossil fuels. Carbon dioxide originates from the burning of fossil fuel, used to power agricultural machinery. However, these direct emissions from agriculture are comparatively small, only making up about 1% of global, human-induced emissions.

Farming in particular releases significant amounts of methane and nitrous oxide, two powerful greenhouse gases. Additionally, cattle farming produces methane as waste gas.Methane is produced by livestock during digestion due to enteric fermentation and is released. Rice cultivation in paid fields also contribute to the increase of greenhouse gases in the atmosphere]]> 2021-03-25 05:47:57 UTC https://padlet.com/lim_ai_jia_dawn/3urgic59y6awefp3/wish/1351353699 Yunji Natty Licia Crystal Natalie https://padlet.com/lim_ai_jia_dawn/3urgic59y6awefp3/wish/1351364978 Agriculture leads to enhanced the greenhouse effect such as the cultivation of rice. Firstly, tractors run on fossil fuels which releases Carbon dioxide. Also, the use of inorganic fertilisers increases the amount of the nitrous oxide in the soil. When rain flows through the soil or the soil is ploughed, nitrous oxide is released. Moreover, organic matter such as dead leaves releases methane during decomposition. Decomposition in the rice field is very rapid as there are the high level of moisture in soil. Hence, releasing of Carbon dioxide, nitrous oxide and methane which are the greenhouse gases that will lead to enhanced the greenhouse effect.]]> 2021-03-25 05:53:15 UTC https://padlet.com/lim_ai_jia_dawn/3urgic59y6awefp3/wish/1351364978 Darren Matthew Ezell https://padlet.com/lim_ai_jia_dawn/3urgic59y6awefp3/wish/1351392099 As the world  population grows, the demand for basic necessities , such as food increases exponentially. To accommodate the growing demand, the need for readers . Forest are cleared to provide more farmland as the deforestation of forests mare considered a more feasible option.Forests lies on arable land and often have better conditions for crop production or raising livestock. Since forest are being deforested, more green house gases are produced as a result of fewer trees]]> 2021-03-25 06:06:12 UTC https://padlet.com/lim_ai_jia_dawn/3urgic59y6awefp3/wish/1351392099
