The Effects Of Hydraulic Fracturing On The Environment

Dangers of Hydraulic Fracturing Despite its many advantages, hydraulic fracturing poses serious threats to the environment. Some of the commonly identifiable effects of hydraulic fracturing include water pollution, over depletion of water resources, noise pollution, air pollution as well as contributing to land movements such as tremors and earthquakes (Boudet et al. 57). According to Boudet et al. (58), fracking presents challenges that prompted the Environmental Protection Agency (EPA) to commence investigations into the environmental effects of hydraulic fracturing. Fracking is a capital-intensive project that usually involves the clearing of lands, transportation of water resources, construction of critical infrastructures such as†¦show more content†¦According to a survey conducted by Anderson Theodori (135), the residents of Texas readily point to the accessibility to the right jobs and better living standards as some of the benefits of hydraulic fracturing. The residents are however quick to singl e out the fact that the availability of employment in Texas has also strained public utilities and social goods such as education, healthcare and even recreational facilities (Rahm 2981). Be that as it may, the residents identify many positive impacts and do not want hydraulic fracturing to be stopped. Controversies around Hydraulic Fracturing Some of the problems associated with hydraulic fracturing include a strain on the water resources in the State of Texas. The residents sampled in the Anderson and Theodori (131) survey asserts that fracking strains their water resources and forces them to reduce their water consumption. The residents were concerned that the continued over-exploitation of their water resources might, in the long run, result in depletion of the scarce resource (Gregory, Kelvin, Radisav, Vidic Dzombak 184). The quality of the water consumed by residents living in areas where fracking is conducted is a cause of primary concern. Given the fact that the water extracted from the mines is usually released back into the ecosystem, there isShow MoreRelatedHydraulic Fracturing And Its Effects On The Environment1087 Words   |  5 Pages Hydraulic Fracturing Maya Murray Mr. Iwasaki Chun MYP Chemistry Essay 3 May 2015 Maya Murray Mr. Iwasaki Chun MYP Chemistry 3 May 2015 Hydraulic Fracturing â€Å"Our country will have drilled and fracked our way down a blind alley for a short lived energy boom† (qtd.

These areas will be explored throughout this document. 1 What is Hydraulic Fracturing The United States Geological Survey Energy Resources Program defines hydraulic fracturing as an oil and gas well development process that typically involves injecting water, sand, and chemicals under high pressure into a bedrock formation via the well (Hydraulic Fracturing). The process is meant to produce fractures in the rock formations which increases the flow of oil from the bedrock to the wells, where it can then be processed into crude oil (Hydraulic Fracturing). Despite being a fairly new method of extraction, fracking has quickly become one of the top methods in use. 2 Water Conditions in Texas. In June of 2014, 70 percent of Texas was in drought; of that 70 percent, 21 percent was classified as being in a state of extreme or exceptional drought (Everything You Need...). In 2013, the state climatologist said part of the cause of the drought was the climbing temperatures due to climate change (Everything You Need...). The climatologist stated that the average temperature in the State of Texas has increased an average of 2 degrees Fahrenheit since the 1970s (Everything You Need...).

This organization allows corporations to publicize the chemicals used of the gas production proce ss. In 2012, there were 17,000 disclosures reported from about 135 companies, (Pliss, p.2). In 2011, the Fracturing Responsibility and Awareness of Chemicals Act was proposed in Congress (Palliser, 23). This act would mandate hydrofracturing companies to disclose all chemicals used in the process. Passing this act would allow the Drinking Water Act to set standards to corporations. However, the Drinking Water Act is exempted by the fracturing industry. Hydraulic fracturing impacts the environment and human health, regulated by the EPA. The EPA oversees the hydraulic fracturing by making sure the companies have the required permit. Additionally, this organization ensures the safety of wastewater from hydraulic fracturing by correct disposal. Also, they provide ways to reduce the air emission especially from methane, commonly distributed during the fracturing process. Furthermore, Senate Fran Pavley, introduced a bill that would notify land owners about the process of hydraulic fractu ring, and a ground water testing for any contamination present (Palliser, 23). Senate Pavley stated that this bill would ease some tension for some people, those concerned about the environmental status of their community. Some states think that fracking should be avoided

The Colonization Of Africa Is A Significant Reason Why The...

The colonization of Africa is a significant reason why the educational system in Africa is split between the countries it holds. Between the late 1800s and early 1900s Africa faced many military annexations and diplomatic conquests. The impact of colonialism has influenced the conflicts in Liberia that happened in the late 1900s. Liberia s civil wars held a responsibility for the devastation that is implicated in its racial stance. Social Darwinism gave support for the superior rule over Africa. Liberia s conflicts play a notable role in how westernization of education and race are viewed throughout Africa. Liberia s education system emerged because of these conflicts. Colonizing Africa began between the 1870s-1900. An important tragedy of colonization is the stripping of ethnicities. Modern Africa is a product of European imperialism, not African heritage and tradition. Once the profits of the slave trade collapsed, because of its abolition, European markets were looking for ways t o keep a steady way to make profits. Traditionally, Africa had been divided into groups by tribe, family, clan and lineage. During the process of colonization these characteristics were social, economic and political. Colonial state formation caused new values, institutions and operational principles to take place. The African colonization required the taking of territories that were unknown to the political world.

Persian Wars Essay Example For Students

Persian Wars Essay The Persian Wars In the 5th century BC the vast Persian Empire attempted toconquer Greece. If the Persians had succeeded, they would have set up localtyrants, called satraps, to rule Greece and would have crushed the firststirrings of democracy in Europe. The survival of Greek culture and politicalideals depended on the ability of the small, disunited Greek city-states to bandtogether and defend themselves against Persias overwhelming strength. Thestruggle, known in Western history as the Persian Wars, or Greco-Persian Wars,lasted 20 yearsfrom 499 to 479 BC. Persia already numbered among its conqueststhe Greek cities of Ionia in Asia Minor, where Greek civilization firstflourished. The Persian Wars began when some of these cities revolted againstDarius I, Persias king, in 499 BC. Athens sent 20 ships to aid the Ionians. Before the Persians crushed the revolt, the Greeks burned Sardis, capital ofLydia. Angered, Darius determined to conquer Athens and extend his empirewestward beyond the Aegean Sea. In 492 BC Darius gathered together a greatmilitary force and sent 600 ships across the Hellespont. A sudden storm wreckedhalf his fleet when it was rounding rocky Mount Athos on the Macedonian coast. Two years later Darius dispatched a new battle fleet of 600 triremes. This timehis powerful galleys crossed the Aegean Sea without mishap and arrived safelyoff Attica, the part of Greece that surrounds the city of Athens. The Persianslanded on the plain of Marathon, about 25 miles (40 kilometers) from Athens. When the Athenians learned of their arrival, they sent a swift runner,Pheidippides, to ask Sparta for aid, but the Spartans, who were conducting areligious festival, could not march until the moon was full. Meanwhile the smallAthenian army encamped in the foothills on the edge of the Marathon Plain. TheAthenian general Miltiades ordered his small force to advance. He had arrangedhis men so as to have the greatest strength in the wings. As he expected, hiscenter was driven back. The two wings then united behind the enemy. Thus hemmedin, the Persians bows and arrows were of little use. The stout Greek spearsspread death and terror. The invaders rushed in panic to their ships. The Greekhistorian Herodotus says the Persians lost 6,400 men against only 192 on theGreek side. Thus ended the battle of Marathon (490 BC), one of the decisivebattles of the world. Darius planned another expedition, but he died beforepreparations were completed. This gave the Greeks a ten-year period to preparefo r the next battles. Athens built up its naval supremacy in the Aegean underthe guidance of Themistocles. In 480 BC the Persians returned, led by KingXerxes, the son of Darius. To avoid another shipwreck off Mount Athos, Xerxeshad a canal dug behind the promontory. Across the Hellespont he had thePhoenicians and Egyptians place two bridges of ships, held together by cables offlax and papyrus. A storm destroyed the bridges, but Xerxes ordered the workersto replace them. For seven days and nights his soldiers marched across thebridges. On the way to Athens, Xerxes found a small force of Greek soldiersholding the narrow pass of Thermopylae, which guarded the way to central Greece. Leonidas, king of Sparta, led the force. Xerxes sent a message ordering theGreeks to deliver their arms. Come and take them, replied Leonidas. For two days the Greeks long spears held the pass. Then a Greek traitor toldXerxes of a roundabout path over the mountains. When Leonidas saw the enemyapproaching from the rear, he dismissed his men except the 300 Spartans, whowere bound, like himself, to conquer or die. Leonidas was one of the first tofall. Around their leaders body the gallant Spartans fought first with theirswords, then with their hands, until they were slain to the last man. ThePersians moved on to Attica and found it deserted. They set fire to Athens withflaming arrows. Xerxes fleet held the Athenian ships bottled up between thecoast of Attica and the island of Salamis. His ships outnumbered the Greek shipsthree to one. The Persians had expected an easy victory, but one after anothertheir ships were sunk or crippled. Crowded into the narrow strait, the heavyPersian vessels moved with difficulty. The lighter Greek ships rowed out from acircular formation and rammed their prows into the clumsy enemy vessels. Twohu ndred Persian ships were sunk, others were captured, and the rest fled. Xerxesand his forces hastened back to Persia. Soon after, the rest of the Persian armywas scattered at Plataea (479 BC). In the same year Xerxes fleet was defeatedat Mycale. The threat of Persian domination was ended.
