The bad news for us is that oil, along with a few other resources, are fossil fuels. Almost everyone’s daily life uses fossil fuels in one way or another. The big question that not many people ask or know the answer to is; what are fossil fuels? To find out what fossil fuels are, we must first know how they were formed. They were at first actual living organisms. “They were formed from prehistoric plants and animals that lived hundreds of millions of years ago” (Department of Energy, N.d, p.1). Examples of fossil fuels are oil, coal, and natural gas. All three of these resources are given a term “non-renewable.” This is because once we use all of these resources up, they are gone forever. These non-renewable resources also cannot be replaced in our lifetime. There is only a certain amount of these fossil fuels left in the Earth for us to be able to use. To better understand fossil fuels, we need to look at each one separately. The first fossil fuel that most people think of is oil. “Oil was formed from layers of sediments rich in the remains of tiny (microscopic) plants and animals. As the layers were buried deeper and deeper below younger layers of sediment, the plant and animal
