The United States is one of the foremost countries in the use of fossil fuels.  Fossil fuels are those that are formed in the ground, naturally, over a period of millions of years. They are usually formed from dead plants and animals. 

Oils, natural gases, and coal are the most common fossil fuels and all around the world, we depend on them use a lot of them, but slowly the reserves are being depleted and the costs of extraction are soaring!

Fossil fuel usage by humans is the largest single source of emission of carbon dioxide, which is one of the greenhouse gases that allows radiative forcing and contributes greatly to global warming. 

When fossil fuels are burnt, they let out a large amount of carbon dioxide.  The atmospheric concentration of CO2, a greenhouse gas, is increasing radically.  This raises concerns that solar heat will be trapped and the average surface temperature of the Earth will rise, directly in response to that. Remember "for every action, there is an equal, opposite reaction".

Fossil fuels are used to power our vehicles, heat and cool our houses and generate electricity.  As it takes millions of years to form certain fossil fuels and over usage of them has resulted in concerns that we will soon deplete our supply of natural power reserves.  Fossil fuels are non-renewable sources of energy, so once they are used up, they are gone for ever.

Crude oil is the most valuavle of these fossil fuels. The United States alone, uses about twelve barrels of oil per person, per year. This illustrates how dependent the population is on foreign oil, to meet their energy needs.  While the United States does have it's own oil reserves, it isn't nearly enough and doesn’t compare to what is available in the Middle East regions.  So, in order to meet the demand, they obviously have to import supplies from other countries, such as Venezuela or Saudi Arabia.

The increased levels of fossil fuels used in the U.S and around the world, has given birth to the "green movement," which urges people to start exploring alternative forms of energy, to avoid depleting our fossil fuel supplies completely.  An even bigger and more frightening reason is because the greenhouse gas emissions are now causing global warming, that can have an enormously detrimental effect on the lives of people all over the world.

If we can reduce our use of fossil fuels and start looking at alternative sources of energy, we will not only improve the quality of the environment, but we can also reduce our dependence on other countries for energy resources. We all need to be more self sufficient and power efficient, by using alternative energy, that does not destroy our planet.

When it comes to decreasing our fossil fuel usage and becoming self-sufficient with alternative fuels, it can mean so much more to our environment and our future!
