it is observed that although the non-renewable energy sources generate less electricity compared to the use of fossil fuels, they, however, do not emit the harmful greenhouse gases that adversely affect the environment.
220.127.116.11 Agricultural sector
Agricultural activities such as cultivation and livestock manure, which, as reported by Shaheen and Lipman (2007), generate mainly methane and nitrous oxide. The EPA (2017) also reported that in the US, agricultural activities such as rice production, livestock, and soils contributed to 9% of greenhouse emissions in 2017. The Livestock and Poultry Environmental Learning Community (LPELC, 2019) reports that the greenhouse gas emissions in agricultural activities arise from four main types of activities: 1) soil management, 2) enteric fermentation, 3) manure management and 4) energy use (LPELC). This is represented by figure 7 below.
