the sugars are distilled to make ethanol
Recycling Carbon In this view of the carbon cycle, ethanol production does not introduce new carbon into the atmosphere, but rather recycles the carbon existing in the atmosphere.
carbon dioxide (CO2) and carbon monoxide (CO) emissions in flex-fuel vehicles (FFVs) by as much as 70 percent. With a 70 percent reduction, smog-encased cities like Los An-
geles could help to make a better environment for all of their inhabitants. By using E85 in larger quantities, our fuel can help the environment, and decrease our dependence

on foreign oil for fuel. The carbon cycle illustration shows how growing our own fuel will benefit the environment. Understanding how carbon travels in our atmosphere is crucial to understanding that the more fuel produced from petroleum the higher the levels of CO2, CO and GHGs in our atmosphere. To help decrease current levels in our atmosphere, alternatives are needed that have lower carbon content, plus a source that can absorb carbon and take it out of circulation. Plants are the best at this process through photosynthesis and respiration. They take in CO2 and release oxygen. Ethanol production helps to ensure our fuel independence, decrease our dependence on foreign oil sources, decrease pollution and greenhouse gas emissions, have a healthier environment for children, increased economic activity that creates jobs, a strong industry and a step toward a cleaner future. Learning how to use what the earth has provided is vital to the future. Success is dependent upon on a willingness to change our habits and move away from petroleumbased fuels.
