scientific controversy

Earth’s population is growing, and so is that population’s need for energy. Most of the world depends on energy from fossil fuels, which include oil, coal, and natural gas. Unfortunately, fossil fuel reserves are diminishing. Predictions differ regarding how long each of these fossil fuels will last. The scarcity of these fuels is not the only topic debated in this controversy. Fossil fuels emit carbon dioxide, and many scientists believe an accumulation of carbon dioxide in Earth’s atmosphere is an important cause of global warming. “Warnings from the scientific community are becoming louder, as an increasing body of science points to rising dangers from the ongoing buildup of human-related greenhouse gases” (New York Times Company, 2011). You may have read about problems with fossil fuels when you prepared for this week’s Discussion on the climate change controversy. Although scientists and other stakeholders may disagree about whether fossil fuel emissions are changing our climate and about how long fossil fuels will last, most agree it is important to develop alternative energy sources. This brings us to another important topic in this controversy: the choice of which energy source to develop. As you have learned in Lies, Damned Lies, and Science, there are trade-offs—that is, risks and benefits associated with any science-related decision. For example, many people support using ethanol as an alternative energy source. One strong benefit is that ethanol does not pollute the atmosphere like fossil fuels do. One downside is that ethanol is made from crops, especially corn. Using corn crops to produce ethanol decreases the availability and raises the cost of this important food staple. For this week’s Annotated Bibliography, you will explore the risks and benefits of a variety of alternative energy sources to recommend a good replacement for fossil fuels.
