Homework Help: Biology Research Paper

Posted by mysterychicken on Tuesday, March 16, 2010 at 6:42pm.

'We are currently in an energy crisis. After food, fossil fuels are humanity's most important source of energy. These resources take millions of years to make. We are currently using the fuels that were made more than 300 million years ago, before the time of dinosaurs. Fossil fuels are a non-renewable resource; once they are gone, they are gone. Compose a research paper that investigates and reports on the biological and environmental aspects of this energy crisis.'

I've got all my information that I need for this research paper, but I need help writing the introduction.
15 points are for:
-A clear thesis statement that expresses the argument, goals, and/or main focus of the paper; thesis statement should be easily recognizable
-Introduces topic with general background information and outlines a road map with development of supporting ideas; provides an overview of what the reader can expect to learn
-Effectively grabs readers' attention and makes them want to continue reading

Here's what I have so far:

Fossil Fuels--An Energy Crisis [Title]

Three major forms of fossil fuels are coal, oil, and natural gas. Coal is a solid fossil fuel formed over millions of years by decay of land vegetation. When layers are compacted and heated over time, deposits turn into coal. Oil is a liquid fossil fuel that is formed from the remains of marine microorganisms deposited on the sea floor. After millions of years the deposits end up in rock and sediment where oil is trapped in small places. Natural gas is a gaseous fossil fuel that is versatile and abundant. Like oil, it is formed from the remains of marine microorganisms.

Combustion of fossil fuels is considered to be the largest contributing factor to the release of greenhouse gases in the atmosphere. There are many types of harmful outcomes which result from the process of converting fossil fuels to energy. Some of these include air and water pollution and accumulation of solid wastes. When coal is burned, it releases nitrous oxide which is kept in the atmosphere for a very long time. The harmful impact of this chemical could take up to a couple of hundred years to make itself known. Converting fossil fuels may also result in accumulation of solid waste. This type of accumulation has a devastating impact on the environment. It also increases the risk of toxic runoff which can poison surface and groundwater sources for many miles. Toxic runoff also endangers surrounding vegetation, wildlife, and marine life.

To reduce our society’s dependence on fossil fuels, we can use some alternative renewable sources of energy like nuclear fusion. Fusion involves the extraction of hydrogen from water and the combination of two hydrogen atoms to form helium. Another source is hydrogen. Most schemes for generating hydrogen are based on the splitting of water using solar energy directly. Hydrogen can substitute natural gas. The last source we can use is energy plants. Active improvements in bioengineering may provide the basis for enhancing the efficiency or redirecting the end products of photosynthetic processes to produce commercial fuels such as hydrogen.

There are new innovations in technology that are currently being explored and implemented to help reduce our dependence on fossil fuels. For example, concepts for combining end uses and supply generation facilities to better utilize waste heat are already being employed. These include cogeneration of steam, electricity, and district heating. Future combinations may include the use of nuclear energy to generate heat for coal gasification. With these options we can help phase out our dependency on fossil fuels and find clean and useful sources of power.

The biological impacts as a result of the use of fossil fuels can harm the living organisms in the area. Oil spills and air pollution, which are also an environmental impact, can harm farm crops, rain forest plants, insects, animals, and even humans.

I also need to find out how to write a good conclusion for this. Please help!
