According to the author of the nonfiction book, This Changes Everything, how is fracking more dangerous and much dirtier than conventional oil and gas extractive activities?

According to Klein, it is considered more dangerous and much dirtier than conventional oil and gas extractive activities. Methane leaks are common during fracking. Klein adds that methane warms at a temperature that is six times greater than carbon dioxide.

Klein writes that for years the U.S. gas industry has claimed that there is no connection between fracking and tap water that nearby residents could literally set on fire. The fracking industry was inexplicably excluded from federal monitoring and regulation. It was called the Halliburton Loophole that was established under the George W. Bush administration. According to Klein, since then there has been a wealth of evidence that fracking puts drinking water at risk. The methane in water near fracking sites was found to be six times denser than that found in normal water sources. Klein writes that earthquakes have also been tied to fracking operations. While fracking extraction shows little visible damage, the process is much more disruptive to the ecosystem than the drilling and extraction of crude oil.
