Danielle Myers12-1 Hydraulic fracturing(also known as fracking) is a highly controversial topic to those that keep up with current government issues. Although many people believe that fracking is malicious‚ it is potentially one of the greatest ideas for America‚ and could end our distress very quickly. The only negative responses to fracking are coming from relatively uninformed people. Fracking has both environmental and economic advantages. Many people are uninformed about fracking. Some

• Each gas well requires an average of 400 tanker trucks to carry water and supplies to and from the site • It takes 1-8 million gallons of water to complete each fracturing job • The water brought in is mixed with sand and chemicals to create fracking fluid. Approximately 40‚000 gallons of chemicals are used per fracturing. • Up to 600 chemicals are used in fracking fluid‚ including known carcinogens and toxins such as… lead‚ uranium‚ mercury‚ ethylene glycol‚ radium‚ methanol‚ hydrochloric acid

Gasland‚ by Josh Fox‚ a Strong Argument against Hydraulic Fracturing Gasland‚ a documentary by Josh Fox‚ details the dangers of hydraulic fracturing. The film starts when Fox receives an offer from a gas company to rent his land and drill for natural gas. He travels across the United States investigating the affects in places where fracturing has is already established. Fox provides a strong argument that hydraulic fracturing is a danger to the environment and residents where the drilling occurs

"How Is Helium Produced?" Production: Although Helium is one of the most common elements in the universe it is a rare gas on earth. It exists in the atmosphere in such small quantities (less than five parts per million) that recovering it from the air is uneconomical. Helium is produced as a by-product of the refining of natural gas‚ which is carried out on a commercial scale in the USA and Poland. In these areas natural gas contains a relatively high concentration of Helium which has accumulated

The concept is very similar to sudden expansion in pipe flow‚ except that hydraulic jumps occur in open-channel flow. At

What is fracking? Fracking‚ formally known as Hydraulic Fracturing‚ is the process of drilling straight down into the earth‚ then drilling horizontally to create cracks in the ground. A combination of water‚ sand‚ and added chemicals are pumped at a high pressure to expand and hold the cracks open to extract the gas. It is a technique that has been used in the United States for over 60 years‚ and many more to come (Bierstedt 641). The thing many people are concerned about is fracking’s effect on

Guatemala and the U.N. Security Council The history of Guatemala in the United Nations began on November 21‚ 1945 (UN). There is not much history written about Guatemala in the United Nations‚ but it entered the U.N. shortly after its formation. The issue of Guatemala’s policy towards other nations is also pertinent to its role as a member of the United Nations. One of Guatemala’s key points when it comes to their foreign policy‚ is its insistence that it “maintain and foster links of cooperation
