According to the Greenies, Fracking is seriously dangerous for the environment.  To prove it, they protest Fracking using signs held together by PVC pipe; which is a by product of, you guessed it: OIL.

Just in case you aren’t familiar with what Fracking is: Fracking is short for Hydraulic Fracturing:

Fracking, or hydraulic fracturing, is the process of extracting natural grass from shale rock layers deep within the earth. Fracking makes it possible to produce natural gas extraction in shale plays that were once unreachable with conventional technologies. Recent advancements in drilling technology have led to new man-made hydraulic fractures in shale plays that were once not available for exploration. In fact, three dimensional imaging helps scientists determine the precise locations for drilling.

Horizontal drilling (along with traditional vertical drilling) allows for the injection of highly pressurized fracking fluids into the shale area. This creates new channels within the rock from which natural gas is extracted at higher than traditional rates. This drilling process can take up to a month, while the drilling teams delve more than a mile into the Earth’s surface. After which, the well is cased with cement to ensure groundwater protection, and the shale is hydraulically fractured with water and other fracking fluids.

Defective Casings allow natural gas can escape into water wells.  It’s not the technology of fracking, it’s the processes used that can contaminate water sources.
