Dangers of fracking : The most common chemical used for hydraulic fracturing in the United States in 2005–2009 was methanol, while some other most widely used chemicals were isopropyl alcohol, 2-butoxyethanol, and ethylene glycol. Fracking Problems Infograph
A new video from the Sierra Club, featuring actor Joshua Jackson, suggests that the oil from Canada's tar sands might not be in Americans' best interest. Jackson says in the clip, "Americans take on all the risks, while oil companies collect all the rewards."
Hydraulic fracturing, AKA "Fracking", is a dangerous new method of extracting gas and oil from rocks at a depth of 2,000 to 10,000 feet down into the shale (soft, sedimentary rock formed from consolidated mud or clay) where one finds natural gas. First, deep wells are drilled straight down through the aquifer (the mixture of soil and water from which life-sustaining water is extracted). This could ruin water supplies for an eternity.
