The greenhouse gas effect is when heat from the sun's rays reflect off of the earth and are absorpbed by greenhouse gases creating a warmer environment. Greenhouse gases are gases that trap heat in the atmosphere. 14% of the world's GHG emissions comes from agriculture. There are three main gases: Carbon Dioxide comes from the production of livestock and the burning of savanas and crop residues Nitrous Oxide is emitted from chemical fertilizers, microbes in the soil, and livestock flatulence and manure Methane is produced primarily through enteric fermentation which is when micro-organisms break down carbohydrates for absorption. Methane is over 20 times greater at trapping heat than carbon dioxide. 66% of emissions in agriculture are related to animal products, 12% are from synthetic fertilizers, 10% from rice cultivation, and 5.7% from the burning of crop residues and deforestation.
