FOOD VS. FUEL
 
 
 
                        
 
            Appose to many people who say that Biofuel will dismantle the food industry, I think that it is a viable and growing solution. We need to support this field of work because as far as I can see it is the most promising solution to our global warming problem. Biofuels are an alternative fuel sorce made to try and decrease CO2 emitions. This post is in response to the food vs. fuel dilema. The food vs. fuel dilema refers to how people think Biofuels will impact the food industries in a negative way. I'm going to difuse the concerns that so many of my classmates have about Biofuels.

 
The first thing I want to bring up is Switchgrass. One of the most important things about switchgrass is that it can be grown in unusable soil. In an article about the first annual Biomass conference a man named Tilman said the test plots were "on land that is incredibly unproductive with very infertile soils. We did not water. We put out high diversity native prairie and let them grow." The energy production from the harvest was incredibly high. Tilman was also quoted saying that there was a large amount of carbon being stored in the soils. This is very important because according to this we will not need to use farm land to grow Biofuels. We will not take any land away from food productions.
 
Switchgrass is impressive in more than one way. For example, switchgrass ethanol can yeild 540% more energy than is required to produce it. This information was found in a National Geographic article entitled ""Grass Gas"" Shows Promise as Superefficeint, clean fuel". It also says switchgrass ethanol releases 94% less green house gas than burning gasoline does. Daniel karman was quoted saying "The result is very important-namely that yeilds can be higher and inputs lower than had previously been expected."
 
Another big problem that people tend to have about Biofuels is carbon debt. Carbon debt is the amount of carbon dioxide that is emitted when land is cleared for crops and the time it takes to get rid of it. Most Biofuels build a carbon debt that would last for decades and even centuries. This is a big problem because global warming needs to be fixed as soon as possible, but switchgrass gets rid of its carbon debt in only 17years.
 
Lastly, I would like to point out that our work with Biofuel is still fairly new but shows extreme promise. Vogle said it is too early to know what percent of the U.S. energy mix could come from switchgrass but the potential is significant and would benefit the environment and economy. It also says switchgrass breeds will continue to improve as will techniques for converting the grass into fuel.
 
I believe that Biofuels are a huge step forward but more progress is to be made to judge it now would be unwise but it shows great potential and is continuing to grow. I believe we need to invest in this field of work so that more answers can be found. If in 17years we could be moving steadily forward toward diminishing global warming.

p.s mes.gardner, I got off work at 10 and got home at 11. also iwoked today at 10 and got off at 3 so i got this done as quocly as i could. forgive me!!
