Once there is a way of efficiently converting biomass to bio-fuels, the pressure applied on food production by bio-fuel energy should dissipate and make this a choice source of energy in the future.Bio-fuels have raised concerns with dieticians, nutritionists, biologists, and farmers with regards to supply of food (Demirbas 31). A question that this technology raises is whether the use of popular food crops for the production of energy is sustainable. Over the period when it has been used, input costs have skyrocketed such as machinery, storage, fertilizer, pesticides and seeds. This has led to a carry-on effect to the consumer. Additionally, aggressive farming techniques have seen soil erosion and depletion that have caused a discernible decrease in crop yields, thus decreasing food supply to the consumers.Farmers in the Mid-west have begun to devote more of their land to the production of corn, which has led to a perpetuation of mono cropping that has led to a decrease in bio-diversity (Demirbas 38). Although the change may not be immediately discernible, the results will eventually transform the supply of food and the way people eat. Subsidization of agricultural products meant for energy production portends a huge influence on the health and nutrition of the American people. When mono-crops become the norm, food supply diversity dwindles and this will be reflected in the diets of the American people. Furthermore, as more crops are directed towards ethanol production, their price will fluctuate. As corn demand rises, its price will also increase leading to a rise in cost of eggs, poultry, dairy products and beef. This will prove critical to families with low income devoting 30-40% of their budgets towards food, as well as to the budgets of nutrition programs in the US that deal with such programs as food stamps and nutrition for pregnant women and children.Bio-fuels could potentially reduce the emission of greenhouse gases since the carbon found in the plant matter that forms bio-fuels is produced from carbon that is taken in by these plants during their lifetime (Demirbas 76). This contrasts with fossil fuel carbon that has been locked underground for over a million years and which gets released into the atmosphere after these fuels undergo combustion.Bio-fuels lead to significant lower emissions compared to fossil fuels, although the emission of
