Prior to watching Gasland 2 and Truthland, I am familiar with the term “fracking” but never took the time to look into it. After watching these two films, I realized how fracking is a controversial topic in the world of environmentalists. These two very different films explain how fracking is effecting the environment around us. Before explaining further into these films, we need to know what fracking really means. Fracking is “a process by which the rock is split so that natural gas can flow to the surface,” defined by Terry Engelder, a professor of geosciences at Penn State University.
In the second article "Fracking Threatens Everyone" it is stated "Fracking remains a dangerous practice that poses a threat even if it is done correctly and is carefully monitored" so it seems that the author wants people to stop Fracking because it generates dangers. It is stated "sources of drinking water can be ruined and all different types of pollution can happen in a second" which poses a great threat to many places. For example, the pollution can enter streams and rivers and kill whatever is in it, and harm even more wildlife. It says "This makes fracking a gamble for communities and individuals who may be tempted by the large amounts of money being offered to those who allow their land to be used for fracking" and the author
Fracking the Good and The Bad In the essay, “Hope It’s in Your Backyard,” by Neil deMause, he wrote about the positive and negative factors of fracking and its effect on the world. The ramifications of fracking could be devastating to the earth with regards to natural gas and oil. It is debated that fracking, in the United States, would stimulate economic growth, lower gas prices, create more jobs, and make our country independent for oil and natural gas. The effects of burning fossil fuels is negative to the earth’s climate and the cause of some pollution. Natural gas is cheaper, but its effect on our ecosystem may be devastating.
FRACKING AND ITS CRITICISM Since the mid-80s, The First Nations and their leaders have raised numerous concerns about the failure of the government and industries in Canada to properly consult them before developing any of their lands. Fracking is a technique used in stimulating the fracturing of rocks through the use of pressurized liquid. The fluid used comprises of hot water, sand, and proppants that are thickened using appropriate agents. The fluid enters the deep-rock and makes it possible to have natural gas, petroleum and brine flow up. If the pressure is removed, the grains in the proppants are capable of keeping the fractures while open.
"Hydraulic fracturing, the process of extracting oil or gas by forcing fluids into the ground to fracture shale rocks, at the Eagle Ford Shale Play has produced more oil and natural gas but at the cost of environmental hazards and affect human health. The part of the process that creates the environmental hazards is the fracking fluids that are forced into the ground. For each fracking job, these fluids are comprised of 1 to 8 million gallons of water and 40,000 gallons of chemicals. Some of the 600 chemical carcinogens and toxins in the fracking fluids are lead, radium, uranium, mercury, methanol, hydrochloric acid, ethylene glycol, and formaldehyde. Once the fracking job is done, about 50 to 70 percent of fracking liquids are left in open
A controversial engineering issues that has people on both sides fighting for and against it is fracking. Fracking or by its actual name “hydraulic fracturing is a type or drilling that involces safely tapping shale and other tight-rock formations by drilling a mile or more below the surface before gradually turning horizontal and continuing several thousand feet more using high pressured water, sand and chemicals” (BBC UK). The high pressure of the mixture will create small cracks on the surface of the material that they are trying to mine, and the purpose of the sand is to keep the cracks from closing back in so that the pressure of the mixture can bring the material up. The material that is mined through fracking is gas and oil. Fracking on one side of the battle is very important to the US energy because it is allowing us to produce our oil fuel supplies
Fracking is a method of extracting natural gas from the earth. A hole is dug deep into the earth. This hole is one to two miles deep (Life Science). The hole also needs to be encased in some strong material so high elevation ground water doesn’t leak in. Once the hole is fully enclosed, high pressured water is shot deep underground (Life Science).
Hydraulic fracking has the capabilities to change the United States economy and improve the lives of many people. Fracking produces large amounts of natural gas that can be used as fuel, but because fracking is such a new process, researchers and environmentalists do not yet fully understand the negative effects it can have on our environment over time. Fracking has been linked to the contamination of groundwater and this contamination is a danger to people who live near fracking sites. The process of hydraulic fracking requires the use of hundreds of potentially dangerous chemicals which need to be regulated to keep our environment safe and clean. Hydraulic fracking should be allowed in the United States because it provides a useful resource,
It involves high-pressure injections of water and chemicals into rock formations, which in turn release natural gas (Thompson, “Hydraulic Fracturing Should Be Banned”). However, fracking can result in many negative outcomes. For instance, scientists who conducted the earthquake study for Geology discovered that not only did fracking cause the biggest earthquake in Oklahoma, but it also caused more earthquakes in states that hardly experienced any seismic activity (“Wastewater Injection Spurred Biggest Earthquake Yet, Says Study,” The Earth Institute Columbia University). In fact, quakes have hit so frequently in Oklahoma, that state and oil regulators decided to shut down five disposal wells due to the increasing number of earthquakes in a city named Cushing (“Oil Regulators Shut Down Two Disposal Wells After Earthquakes Near Cushing”, State Impact: NPR).
There have been many recent studies viewing an increased number of earthquakes in areas affected by fracking. According to the article Introduction to Hydraulic Fracturing, the injected fluids can reach a critical point and can cause a shift in tectonic plates. The frack water injected into the shale has shown to have the ability to shift the earth above causing minor fractures in the rock around the drilled area, which can result in major increases in earthquakes in the fracked area. According to the article Natural Gas Drilling: Impacts of Fracking on Health, the high pressure used to fracture the shale below can continue the cracks, allowing the frack water to flow into the drinking water.
1. Even though fracking reduces carbon emissions, it is still harmful to the environment. For example: water pollution/contamination. There can be accidental seeping of the chemicals (possibly carcinogenic) and can contaminate groundwater around the site due to bad practice (this imposes harm to both the ecosystem and people 's health).
Fracking has actually been taking place since the 1940’s, but not until it was combined with horizontal drilling was it extremely useful (“Hydraulics” 71-75). In the past fifteen years the fracking business has skyrocketed. By 2015 thirty-five thousand wells are using fracking methods in order to extract the natural gases each year. Ninety percent of all gas production in the United States would be impossible without fracking (“Hydraulics” 71-75). More than ninety percent of natural gas wells in the U.S. rely on fracking (Howarth, Ingraffea, and Engelder).
Some people believe that the environment isn 't being harmed by everyday production, but one can argue that as people move closer to fracking industries, people become exposed to harmful gases and chemicals. Fracking a destructive force, is it safe, is it reasonable, is it right? As Chris Hedges explains in his article “Death By Fracking”, he says, “There are more than 15 million Americans, many of them children, who live within a mile of a fracking site. Most are being exposed daily to a deadly brew of toxins. Because the oil and gas industry is not required under law to disclose the chemicals used in
Ever heard of fracking? Fracking is a method used to extract natural gas from deep underground that is used as energy. Fracking is a way of producing energy for everyday use. Fracking is good for the economy, it's safe and it is a viable energy source. Although people say that fracking is bad for the environment statistics show that fracking is perfectly safe.
People complain about pollution from factories, cars, global warming, and the melting of polar ice caps, yet many people disregard the dangerous that come with fracking. Fracking is the process of injecting liquid at high pressure into subterranean rocks, and/or boreholes to force open existing fissures and extract oil or gas. Fracking is causing an epidemic economically and environmentally. Fracking is continuously destroying the earth day by day. From the endless fracking today’s economy is depleting.
