On April 22, 1997 Jared Diamond, an American scientist, author, bio geographer, and professor, addresses the topic of patterns in human history and conquests taken place around A.D. 1500 in “Why Did Human Unfold Differently Continents for The Last 13,000 Years?” to the Edge Foundation. Diamond uses proximate reasons like military and technological advantages, the spread of contagious diseases introduction by the Europeans, the political organization and writing. I agree with his views that other things being equal, the rate of human invention is faster and the rate of cultural loss is slower in areas with with competing societies and in contact with societies elsewhere. I believe he used more proximate reasoning because those are most commonly known. His purpose is to understand so we don’t repeat history. Also he wants to provide us with a convincing alternate explanation to the currently racist in order to eradicate racist theories. He adopts an informative tone for his audience members of the Edge Foundation and others interested in the topic. Diamond's approach on analyzing human evolution takes a more scientific route. History and biology are both intertwined in his reading.
Hydraulic fracking, commonly known as fracking, is a way of extracting oil and natural gas from deep inside the Earth. The process starts with a well that is drilled vertically to a depth of one to two miles underground. Once the drill reaches the point at which natural oil and gas is found, the well curves about 90 degrees and continues to drill for more than one mile.
There is no trace of doubt in many American’s minds that Fracking is a huge attack at our environment, the other half, are not aware of the truth. In other words, fracking is a waste of our precious fresh water. Nine million gallons of freshwater is wasted and can never be useful again after being used in the Fracking process. The small amount of water that returns to the surface, or flow back, is laced with hundreds of deadly toxins. This flow back water is usually left in man mad ponds, free to evaporate into the atmosphere and fall as rain. When using biodegrading chemicals one should be especially careful, but many areas in this process are not controlled. The fracking solution fractures the ground underneath the water table to extract natural gas. But fracturing does not just crack the rock, but wedges hundreds of chemicals in breaks that could go on for miles depen...
“We are the Saudi Arabia of natural gas.”-Sen. John Kerry, D-Mass., May 2010. Most know Saudi Arabia has the most oil in the world. Most also know that the United States should cut back on oil use. What better way than using the natural gas that the U.S. has stored in the ground. However many have doubts about the natural gas revolution. Several reports of water contamination have occurred as well as over one thousand documented cases of neurological, sensory, and respiratory damage near fracking wells. Linking fracking to several environmental issues such as, water pollution and disrupting ecosystems, utilizing this technique should not transpire.
Hydraulic fracturing may be thanks to extract gas however in results of that may have variety of potential impacts to the surroundings. Despite hydraulic fracking’s enlargement and customary use, fracking still poses several health and environmental considerations. throughout fracking, controlled liquids square measure injected into trained wells, that cause the encompassing rock to crack open permitting gas and oil flow through the fissures. Countless gallons of water square measure used and an equally massive volume of waste water is generated. Most of the water is rarely repaired and also the keep waste water and fracking fluid will adversely have an effect on the animals and vegetation around it. In conjuncti...
Hydraulic Fracturing releases more methane into the atmosphere than traditional methods of gas production. Hydraulic Fracturing or fracking is a technology used to harvest natural gas from deep underground. Fracking uses water mixed with chemicals, sand, and other materials into shale to crack and release the natural gas in the shale. Hydraulic Fracturing is toxic to our world since fracking releases more methane into the atmosphere and releases toxic chemicals at the surface. People must stop this or else we will all perish to the toxic chemicals.
Fracking, short for hydraulic fracturing, is the process of extracting natural gas from the ground. A well is drilled vertically to the shale layer (where the natural gas is located), then turns ninety degrees and continues horizontally for several thousand feet into the shale. A mix of water, sand, and chemicals is pumped into the

Hydraulic fracturing, or “fracking,” involves injecting massive amounts of water, chemicals, sand and other materials under high pressure into shale formations to break the rock and release the gas trapped inside (McGlynn, 2011). Fracking has been in use since 1947, but only recently has the term fracking entered the public’s vocabulary (Energy In Depth, n.d.). Although there are some benefits, fracking also causes many risks. One of the biggest concerns today are the health issues that affect both humans and animals.
Our nation is on the brink of an energy crisis and alternative means to produce
Frederick Douglas, a famous abolitionist in 1864 sketched the perfect picture of America saying, "In thinking of America, I sometimes find myself admiring her bright blue sky-her grand old woods-her fertile fields-her beautiful rivers-her mighty lakes and star-crowned mountains. But my rapture is soon checked when I remember that all is cursed... " He whet on to finish his statement by describing the bonds of slavery and the shadow it cast on America. The picture of America that Frederick Douglas so beautifully described is slowly changing as the environment wilts and America's economy scours the planet for a solution in these tumultuous times. America must utilize alternative energy in a time of economic crisis to increase employment opportunities and globally impact our environment.
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.
