Introduction
As the threats of climate change have increased, so has research on alternative energy. Alternative energy differs from classic fuel sources (i.e. coal, shale, natural gas) because it uses natural resources that has the ability to be consistently replaced; thus it is also termed “renewable energy.” “Biofuels” are a specific class of renewable energy that refers to biomass (versus other natural resources like sunlight) or harvested metabolites from living organisms that can be converted into a source of alternative energy. In addition to being renewable, these fuel sources also have lower greenhouse gas (i.e. CO2, CH4, etc.) emissions.
The problem is, the creation of biofuels must be balanced with all the other necessities as the human population continues to increase. For that reason, clean energy must compete minimally with human necessities—both basic and privileged. Society has become so dependent on energy that it has become a human necessity, because of this, the careful balance of food, energy, and the environment has been coined the “environmental trilemma” (tillman). As the human population increases, not only does the necessity for energy increase, but a need for a firm economic infrastructure increases as well. However, has directly correlated to an increase in the use of non-renewable fuels and greenhouse gas emission which further exacerbates the potential for global warming. Additionally, the effect of fertilizers on the environment must also be…
