Since the industrial revolution,oil energy consumption has risen considerably.The majority of this energy consumption is supplied by fossil fuel like coal and natural gas.For some time,there has been a lot of talk about the controversial method of extracting natural gas i.e Fracking or Hydraulic fracturing.In simple words,Fracking describes recovery of natural gas from the deep layers inside the earth.In this method porous rock is fractured with the use of water,sand and chemicals in order to release the enclosed natural gas.This technique has been known since the 1940’s.But only in the last 10 years there has been quite a fracking boom especially in the USA.This is because more conventional natural gas sources in America and Europe have been …show more content…
The Anglers of the Au Sable, a Michigan environmental conservation group, and others, worry that this will deplete freshwater sources and potentially dry up rivers and streams that are key to Michigan's environmental ecological health.
Even though danger is known and theoretically could be managed,no one knows how the enclosed water will behave in the future since there are no long term study on this subject.
The chemicals used in fracking varies from the hazardous to the extremely toxic such as formic acid.Companies are not required to disclose the chemicals they use, or the formula of the mixture, in the process. That makes it difficult for local residents, or first responders, to prepare for an accident or emergency, and difficult for scientists to gauge the threat posed by the chemicals.
Incidences of earthquake occurs in almost every part of the world and hydraulic fracturing only worsens the situation because researches showed that it increases the risk for shaky grounds to take place.Fracking is believed to be the cause of Oklahoma's strongest recorded quake in 2011 and more than 180 tremors in Texas between 2008 and 2009. To start off 2015, an area of North Texas had nine confirmed earthquakes in a 24-hour period. Fracking is being investigated as the
