Genomics
Genomics is the study of the functions of genes and DNA in an organism, including location, structure, sequence, regulation and function. The genome provides a list of building materials for proteins. (Kerns/McDonald, 2001) Today scientists are striving to identify every gene in human DNA and the sequences of the chemical base pairs that make up each one. This is no easy task, but within the next few years, the world will acknowledge genomics as the biggest thing since sliced bread.
Scientists intend to store the data in databases, develop new sequencing technologies, and develop tools for data analysis. Both Celera and the Human Genome Project completed rough drafts of the Genome Project in June 2000 in which approximately 30,000 genes were identified in the human genome. The ultimate goal of the project is to identify the sequence of the human genome and incorporate it into the study of biology and medicine. (Kerns/McDonald, 2001)
The genome project would have been impossible without the work of Frederick Sanger, who developed the dideoxynucleotide method of sequencing, making the sequencing of DNA possible in 1976. In the early 1990’s, scientists undertook one of the largest projects ever when they agreed to map and interpret the functions of every gene in the human body. (“Genomics”, 1998) When the rough draft was completed, Tony Blair quoted, “ . . . implication far surpassed even the discovery of antibiotics, the first great technological triumph of the 21st century.” (Bird, 2000) The Genome Project calculates the discovered genes in EST’s, or gene fragments. Researchers have narrowed these fragments down to a few hundred genes that cause human diseases. ...

Modern biotechnology was born at the hands of American scientists Herb Boyer and Stain Cohen, when they developed “recombinant deoxyribonucleotide, (rDNA), [1] for medicinal purposes. Subsequently, biotechnologists started genetically engineering agricultural plants using this technology. A single gene responsible for a certain trait, from one organism (usually a bacterium) is selected altered and then ‘spliced” into the DNA of a plant to create an agricultural crop consisting of that...
The oil and gas industry has been met with increasing opposition over the years, with fracking and water pollution being some of the most controversial subjects alongside others like pollution, global warming, and claims of corruption. While some anti-frack claims seem like viable arguments, many are the product of misconceptions, an uninformed public. One of the greatest examples of this is Josh Fox’s 2010 documentary GasLand, whose most memorable scene showed a man in Fort Lupton, Colorado, lighting his faucet on fire, blaming it on hydraulic fracturing. After the film was released, among numerous errors it contained, it was found that the water well contained naturally occurring biogenic gas unrelated to oil and gas activity (Energy In Depth).

“Hydraulic fracturing involves the use of water pressure to create fractures in rock that allow the oil and natural gas it contains to escape and flow out of a well (Energy From Shale).” Fracking has served to extract natural gas and oil where other methods would not be as successful but many environmentalists argue that fracking is affecting the environment and our drinking supply of water. Although fracking is still a controversial topic, it provides Americans jobs, increases the economy of the region, and the natural gas and oil are cleaner and more affordable source of energy. The EPA recognizes that natural gas and oil are an essential part to help our planet survive but do not want fracking to come at an expense to the public health of the citizens or to the environment.

There are many problems with “The entire process of fracking – from drilling a well to transporting waste – endangers our water and the health of our communities” (“Fracking”). The process of fracking contaminates drinkable water and many other resources along with it. When rivers or lakes are contaminated it can lead to the extermination of wildlife in that certain area because they no longer are able to breathe due to the amount of chemicals and waste in their habitat. After an accident with a decent amount of exploding trucks, “Twenty-five families living nearby had to evacuate their homes, one person was injured, and toxic chemicals leaked into a nearby stream” (“Act On Fracking”). Companies involved with fracking should either move away from important resources when drilling or completely stop the operation as a whole.
The process of hydraulic fracturing has been around since the 1940’s, though not until recent years has it been an economically viable option. Hydraulic fracturing, or “fracking”, refers to the process of injecting large volumes of water, mixed with a proppant (usually sand) and chemicals, down a well at high pressures in order to fracture underground formations with low permeability. Due to technology advances allowing companies to drill horizontal wells in recent years, the use of fracking has grown exponentially in the United States. This is due to the fact that fracking has allowed oil and natural gas companies to feasibly produce large hydrocarbon supplies in low-permeable shale formations, which were previously thought to be economically inaccessible. This natural gas “boom” caused by widespread use of hydraulic fracturing has provided great opportunities for the United States. By creating a large domestic energy supply, the US has been able to lower dependence on foreign oil imports. Also, natural gas has emerged as a viable fuel source and even burns cleaner than other fossil fuels. Though, fracking has also become a hot topic from an ethical standpoint, with alarming environmental detriments coming to light. With claims and studies that hydraulic fracturing has caused water contamination, water shortages, and even earthquakes, many people are questioning its current use and future viability. Some counties and states are even beginning to completely ban the use of fracking overall. The first canon of the National Society of Professional Engineers code of ethics states that all engineers should “hold paramount the safety, health, and welfare of the public.” (NSPE.org) In order to uphold this code, I believe the env...
Imagine a desolate world where all your drinking water is infected. The ground underneath your feet slowly is deteriorating away and the air is always filled with pollutants, until you can barely breathe.Soon the rain will be acid. Soon this will be our reality. The United States of America, the “the greatest nation in the world,” won't be as great as people say. What is going to be our demise? Fracking. This is a major problem that can happen sooner than you think. Fracking will soon turn this nation into the worst nation in the world. “The fluids used in fracking (and the wastewater that comes back up the well) is disposed of by injecting it into wells deep underground. This is generally the safest, most cost-efficient way to get rid of it. But in some parts of
"You can't get water out of stone," goes the old saying and maybe you can't, but you can get oil and natural gas out of stone with a dangerous practice called fracking. "Fracking is a technique to extract petroleum and natural gas from underground rock formations" (ProQuest). According to Ellen Gilliland, a geophysicist and researcher at Virginia Center for Coal and Energy research, fracking is one of the most controversial practices in the energy industry to develop oil and gas reserves (Gilliland). Kathleen Hartnett, a Harvard graduate, has discovered that fracking causes many environmental concerns such as contamination of drinking water, waste water pollution of rivers, groundwater depletion, air emissions of toxic pollutants, radiation, and even earthquakes (Hartnett). Fracking should not be continued due to the risks it causes to the environment such as damaging property, contaminating water, and polluting the air.

Fracking has significant potential to alleviate our Nation’s dependency on foreign energy supplies; however, stringent regulation and careful monitoring are needed to assuage concerns regarding our nation’s water supplies, the environment and potential for increased seismic activity.
Fracking, also known as hydraulic fracturing or hydrofracking, is the process of natural gas extraction from shale (fine grained sedimentary rock) deep within the earth, and considered a relatively new process. Although the technique of fracking has been known since the 1940s, only in the recent decade has there been a fracking boom. The process of fracking begins with a vertically drilled well, which then turns ninety degrees and continues horizontally into the shale rock layer. A mix of several thousand tonnes of sand, around eight million litres of water, and two hundred thousand litres of various chemicals (known as fracking fluid) is then pumped at high pressures into the well to create fissures which the gas can use to escape. The sand is used to prevent the cracks from closing, the chemicals are used to compress the water, kill bacteria and dissolve the minerals. The natural gas that escapes is then drawn back up the well to the surface, where it is processed and shipped. After the fracking process is completed, wastewater, containing potentially toxic chemicals, returns to the surface. Once the gas source is exhausted, the wastewater is pumped back into the deep underground layers and the well is sealed. This article will address how fracking contributes to water pollution, and the resulting effects.
