The process of hydraulic fracturing has one goal, to extract as much natural gas from the shale as possible. We use natural gas for a variety of different things, including the heating for your home and water, cooking, transportation, energy generation and so much more. (*Use of Natural Gas) The majority of people use natural gas every day of their lives in one way or another. Seeing as hydraulic fracturing is currently the most cost effective way of extracting natural gas from the earth, many companies see this as a fairly easy way to get rich. At the present time, the only way to cost effectively extract natural gas from the shale requires the use of toxic chemicals, which on certain occasions may spill out into the environment.
