Preliminary Outline and Draft - Assignment Example In 10 years to come, approximately 25% of American vehicles will be running on biodiesel. Public health institutions attribute increase in cancer and respiratory complications to pollution from fossil fuels. Undeniably, any alternative fuel that causes less or no pollution would be adopted as a solution to the health impacts of fossil fuels. Recent increase in biodiesel campaigns and consumption is attributed to potential benefits of the fuel. Unlike gasoline, biodiesel is non toxic. Gasoline releases unpleasant fumes upon combustion. On the contrary, biodiesel emit fumes with a pleasant smell, no greenhouse gases and absolute absence of carcinogenic hydrocarbon compounds. Occasionally, air pollutants like carbon dioxide are directly associated with gasoline and other fossil fuels. Carbon dioxide, together with other greenhouse gases causes global warming. Scientific research indicates that global warming will lead to increased desertification, climate change, increased acidity of fresh water and rise in sea levels. Among the identified mitigating factors of global warming include use of less polluting and renewable energy sources like biodiesel. Since biodiesel burns cleanly, it releases negligible amounts of greenhouse gases compared to gasoline. Therefore, biodiesel features as a viable solution to the global warming monster together with other complications related to air pollution. A scientific research exercise will be appropriate in substantiating claims relating to the benefits of biodiesel in addressing issues of air pollution. The research hypothesis asserts that increased use of biodiesel reduces emission of carbon dioxide and air pollution. This hypothesis contains both the dependent and independent variables. A null hypothesis, which contradicts the earlier statement, will be introduced to test the validity and reliability of the alternative hypothesis. Undeniably, biodiesel reduces pollution. However, other sources of pollutants
