Across Seven Seas and Thirteen Rivers

At the outset, this essay identifies the three prime contributors to global warming. These are fossil fuel burning, deforestation and livestock farming. Globally, fossil fuel burning generates 64% of human greenhouse gas emissions, deforestation 18%, and livestock farming between 13% and 18% (estimates from UN Food and Agriculture Organization (FAO) (Skeptical Science, n.d.). Within its limited scope, this essay chooses next to focus on how to reduce greenhouse gas emission due to livestock farming. Because the other two triggers, namely, fossil fuel burning, and deforestation, have already attracted substantial media attention. Thus,   this essay   does not discuss the ways of reducing greenhouse gas emission due to fossil fuel burning and deforestation even though those two are essential too. Instead, it chooses the third of these three prime contributors, namely, the livestock farming sector and narrates how livestock farming contributes significantly to human greenhouse gas
