Ethanol (biomass fuel) Issue**: The earth is now in a state of time where global warming is getting worse due to rising level of CO2. The cause of the rising CO2 level is from the burning of the fossil fuels. If we don't find a alternate energy source soon it could have horrible effects on the world. Some of these effects could be: rising sea levels, temurture increase, melting ice caps, extinction of many plants and aninmals, and more. Burning fossil fules to run our cars is just going to make global warming worse. One alternate source of energy we could use would be ethonal. Ethonal is a biomass fuel that is already being used today. A biomass fuel is energy source that comes from organic material. It has been used as a alternate for gasoline. The only real problems with ethanol is that people think that it is a replacement for gasoline, when really it is only a supplement. With more vehicles using ethanol, the CO2 levels will start to decrease. Ethanol is a biomass fuel, meaning that it is healthy for the earth. When ethanol is mixed with regular gasoline it has a very high oxygen level. With a high oxygen level, it makes the fuel burn faster and better. Ethanol still puts CO2 in the air when it's burned.Thats where you would stop and think, is ethanol is better for the enviornmernt even if it is putting out CO2? If you think that your wrong. Ethanol has a short term carbon cycle. Ethanol is made from corn, and corn needs CO2 to grow. So if the corn is taking just as much CO2 in as ethanol puts out your not increasing the CO2 level at all. Ethanol is a fuel made from corn, grain, and achohol. It is burned with regular gasoline to make the fuel that goes in cars. Ethanol is a biomass fuel that is a healthier alternitive to gasoline.
