There are many controversies about whether we should use fracking or not. Fracking, hydraulic fracturing is the process of injecting liquid at high pressure into subterranean rocks, to force open existing fissures and extract oil or gas. Some people say that fracking is dangerous because it can leak into our underground water reserves. Other people say that fracking is good because it makes extracting oil or gas extremely easy and efficient. Both sides are not wrong because there is 20-40% of oil still left in the ground when the fracking is done, and because fracking is the easiest way to extract oil and gas.
It shows that the oil and gas industry has had several breakthroughs with technology, including hydraulic fracturing. These breakthroughs have found ways to make hydro fracking more environmentally friendly and cost efficient. With any technological developments, there are consequences. For example, there is the possibility of polluting the water supply with chemicals. There is the possible pollution of air as well.
These different sources of energy provide an alternate cleaner source of energy. These energy sources are harmless to the earth, helping to negate the effects of certain forms of pollution. My first choice of energy wind power is the conversion of wind energy by wind turbines into a useful form, such as electricity or mechanical energy. Secondly is hydroelectric power electricity generated by hydropower. Hydroelectricity is the production of power through use of the gravitational force of falling water or flowing water.
Fracking: Let It Flow First, let me explain the process of hydraulic fracturing - fracking. Fracking is the process of harvesting natural gas from far beneath the earth's surface. This process uses horizontal drilling and hydraulic fracturing to release natural gas from shale beds by blasting the rock with high-pressure water and chemicals. This is not a new idea; oil companies have been doing this for over half a century. Natural gas is an excellent alternative to coal or oil because it burns much cleaner.
2013).Pharmaceutical companies sometimes place active chemicals and waste into groundwater sources, in which almost all of the groundwater may be untreated which most likely cause contamination. (Herber, 2002). Abstract: Increase in the emissions of carbon dioxide by burning fossil fuels is the largest cause of environmental down grading resulting not only in global warming but also causing acid rain which alters the pH balance of ground water. Water is a universal solvent; however, its dissolving properties are very sensitive to changes in temperature and pH. Global economic growth has, unfortunately,
The Globe is losing its Cool Global Warming Melissa Moran University of Phoenix Axia collage Professors name SCI 275 October 21, 2009 There are many reasons for the change in the climate. Climate change also known as global warming is the change in the average temperature of the earth surface, and the change in wind and precipitation. Global warming is caused by releasing fossil fuels into the atmosphere. Many factors such as human activity and greenhouse gas emissions contribute to global warming. Global warming also has natural causes though they are often down-played in the media.
Many worry about the negative consequences Global Warming may have on our Earth. It is believed that there will be detremental effects from sea to land. A rise in water levels causing the icecaps to melt. Melting icecaps would then release methane another greenhouse gas. The oceans salt water would mix with freshwater and CO2 would get absorbed into the oceans causing disabling effects on our waters food chain.
During these journeys, many polar bears either drown or get lost. Scientists predict that if the movement of sea ice continues, many bears will drift off to an unsuitable habitat, making it impossible for them to return or survive. Polar bears are already suffering the horrible effects of global warming: bears are drowning, birth rates are falling, and fewer cubs are surviving. If global warming continues polar bears could become extinct by the end of this century (Polar bear SOS). Global warming is the result of greenhouse gases.
The use of chemicals in the hydrofracking process and the energy needed to operate the trucks and drills, critics say, offset the low carbon emissions from the burning of natural gas, making it no better than oil or coal. Furthermore, opponents contend, pollutants left behind at hydrofracking drilling sites could seep out from closed pipes and wells, posing a danger to public health for generations. Therefore, critics say, the federal government must step in to institute stricter regulations than the states have already
Furthermore, the influx of chemicals brought deep into the ground for extraction purposes have mixed with ground water, leading to lethal contamination of local drinking water. Amongst these results, fracking often yields high amounts of methane gases to the atmosphere. If fracking continues at high rates it will evidently threaten local habitats while also contaminating ground waters and while polluting
