Today, it is believed that agriculture has fed over 6,000 million people. In addition, evolution has generated more cereals as compared to the past four decades. In light of this, there has been increasing in the input of fertilizers, water and pesticides, new crop strains with the inclusion of other essential technologies that are related to the Green Revolution (Tilman et al 672).
