It's Time to Drain Lake Powell Many people know ‘Lake’ Powell as a fact of life. Since its creation in 1963, the reservoir, known as Lake Powell, is just there. Few people that are alive today have had the opportunity to see the true beauty of Glen Canyon, which rivals the Grand Canyon. Glen Canyon, equivalent to one hundred eighty river miles with dozens of side canyons, was flooded for the purpose of power and water resources. ‘Lake’ Powell also generates an enormous cash flow due to the tourism it receives. Although the ‘lake’ has a few reasons to remain in existence, there are many more reasons to drain it. The positive aspects of ‘Lake’ Powell are few yet noteworthy. Glen Canyon Dam’s hydroelectric power-plant generates one thousand three hundred mega watts of electricity at full operation. That is enough power to supply three hundred fifty thousand homes. Glen Canyon Dam holds twenty seven million acre feet of water, which is equivalent to twice the Colorado River’s annual flow (Living Rivers: What about the hydroelectric loss?). One of the most valuable reasons for the dam to remain active is that “Lake Powell generates four hundred fifty five million dollars per year in tourist revenue, without this cash inflow, gas-and-motel towns . . . would undoubtedly wilt, and surrounding counties and states would lose a substantial tax base” (Farmer 185). These positive aspects are of no surprise considering they are the reason dams are built in the first place. The negative aspects of Glen Canyon Dam greatly exceed the positive aspects. The dam’s hydroelectric power supply is only three percent of the total power used by the six states that are served by the facility. There is a surplus of power on the Colorado Plateau and with more and more power-plants being created in the western hemisphere, Glen Canyon Dam’s power is not needed (Living Rivers: What about the hydroelectric loss). Although the ‘lake’ contains twenty seven million acre feet of water, one and a half million acre feet of water are lost yearly due to evaporation and seepage into the sandstone banks surrounding the ‘lake’ (Living Rivers: What about the water supply?). The loss of that much “water represents millions, even billions of dollars” (Farmer 183). If the government were to employ more water efficient irrigation practices, as much as five million acre feet of water per year could be saved.
The one feature common to the Hoover Dam, the Mississippi River and the Three Gorges Dam is that they all try to control nature’s swings, specifically in the form of flooding. Before the Hoover dam was built, the Colorado river “used to flood spectacularly.but after 1900 the Colorado provoked a vehement response” (Pg 177). The response was simple, but large. The U.S. built several large dams, including the Hoover dam, on the Colorado to decrease its flooding and increase power and irrigation. Unfortunately, just as human control of the Colorado’s flooding increased, its organisms and habitats were detrimentally influenced, and the water became more and more salinated.

This Paper will describe and analyze three articles pertaining to the ongoing debate for and against Glen Canyon Dam. Two of these articles were found in the 1999 edition of A Sense of Place, and the third was downloaded off a site on the Internet (http://www.glencanyon.net/club.htm). These articles wi...
Not many people know of the used-to-be 150-mile excursion that the Glen Canyon had to offer. Not many people know how to sail a raft down a river for a week. Not many people know how to interact with nature and the animals that come with it. We seem to come from a world that is dependent on time and consumed in money. Edward Abbey is what you would call an extreme environmentalist. He talks about how it was an environmental disaster to place a dam in which to create Lake Powell, a reservoir formed on the border of Utah and Arizona. He is one of the few that have actually seen the way Glen Canyon was before they changed it into a reservoir. Today, that lake is used by over a million people, and is one of the biggest recreation hot spots in the western United States.
As global temperatures and ocean levels rise, the water levels of the Great Lakes continues to fall. As the lakes hit their all time lowest level in global history in 2012, society remains ignorant to the imposing doom that lurks ahead. Since the Great Lakes make up the largest group of fresh water lakes on Earth and are responsible for approximately 21% of the Earth’s fresh water supply, this issue is becoming one of the largest environmental and economical issues our modern world faces. The effects of this issue include destroying animal habitats and a major economic market; shipping. Water levels in the Great Lakes have been dropping for the past fourteen years, but it wasn’t until boats were scraping the bottom of Lake Huron that people began to take notice. This terrible environmental issue has been dubbed a long term cycle of over evaporation and not enough precipitation to replenish the Lakes. Keith Kompoltowicz, chief of watershed hydrology for the United States Army Corps of Engineers in Detroit has been monitoring this issue for a decade and has made startling discoveries, such as in 2012, he discovered Lake Michigan and Lake Huron’s water levels only rose four inches after winter, whereas the Lakes have been regularly recorded as gaining a foot of water after the winter season had ended. This amount of water added is not enough to maintain a proper water level during the dry, hot summer seasons that evaporate much water from the Great Lakes. While some scientists say that this is just a cycle that will adjust itself naturally, most experts that have been studying this phenomenon, such as Kompoltwicz, would agree that the issue has gone to far
Water is the foundational basis of life on Earth. Ecosystems, society and humans are completely dependent on it, and as the world population continues to grow, there will be more mouths to feed, and those people will need water to continue their daily lives. However, shortages and poor management leads to the destruction of natural habitats and human suffering. Desertification of land in China is ever-increasing, turning green, lush land into desert. However, this is due mainly in part, because of human activity, and global warming (Wang, Yang, Dong, & Zhang, 2009). The United States could experience a crisis similarly to China’s, but for now they have averted such a catastrophe, because of heavy regulation of water. Though there are water shortages in many parts of the world, it is unwise to export water from the Great Lakes to those regions. Two major reasons why diverting the Great Lakes is a terrible idea, one: it allows for waters wars to start on the basis of who is allowed to access it and for commodification purposes. Two, diverting water on such large scales could have cataclysmic effects on the local residents as well as the environment.
Since 1960 the age-adjusted mortality rates for cardiovascular disease (CVD) has declined steadily in the U.S. due to multiple factors, but still remains one of the primary causes of morbidity and premature mortality worldwide. Greater control of risk factors and improved treatments for cardiovascular disease has significantly contributed to this decline (Centers for Disease Control and Prevention, 2011). In the U.S. alone it claims approximately 830,000 each year and accounts for 1/6 of all deaths under the age of 65 (Weiss and Lonnquist, 2011). Based on the 2007 mortality rate data an average of 1 death every 37 seconds is due to cardiovascular disease (Lloyd-Jones et al., 2009). Controlling and reducing risk factors is crucial for saving lives. There are a number of contributing risk factors for cardiovascular disease, which may appear in the form of hereditary, behavioral, and psychological, all of which ultimately converge in social or cultural factors.
Edward Abbey's heart lies in the once beautiful Glen Canyon. He describes all of his wonderful childhood stories of him floating down the river and how all it took was a paddleboat and little money. He tells of the great beauty of all the animals, insects, forestry, and ancient scenery the canyon once had. This is why Abbey feels reservoirs are doing terrible things for not only Glen Canyon but every river. When you think about it, a natural river untainted by the ways of machinery and humans is virtually non existent today. Any river large enough to have a dam and produce a substantial amount of electricity probably already has many of them doing so. Abbey feels they are ruining the environment and wildlife is being sacrificed. The risen waters of the reservoir drown all of the life that once lived. All of the beautiful scenery and historic sights are replaced by water marked rocks, muddy banks, and very small amounts of forestry and greenery. He believes the whole river is completely disrupted with every reservoir and dam. He highlights the fact that exploring the river now requires a tour guide boat or enough money to buy your own. Overall, Abbey does give some good reasons behind his opinion. However, I have a different belief on the matter. Although Edward Abbey uses strong personal experiences to persuade the reader to argue that the man made reservoirs are destroying the beautiful canyon and the environment, I think he overlooks the other possible opinions and the benefits of having them.
“… The difference between the present reservoir, with its silent sterile shores and debris-choked side canyons, and the original Glen Canyon, is the difference between death and life. Glen Canyon was alive. Lake Powell is a graveyard.” – Edward Abbey, “The Damnation of a Canyon”, Beyond the Wall
The first step taken in karyotype test is by taking a sample of your Mitosis cells. These samples can be taken from various tissues, including bone marrow, amniotic fluid, blood, or placenta. The sample is then placed in a laboratory dish that allows the cells to grow and multiply. Then the dividing cells are stopped in metaphase by treating it wit...
Nevada’s population is increasing, in particular Las Vegas’ population, which is causing the water supply to decrease in the state (Brown, n.d.; Larson et al., 2015). Lake Mead provides Colorado River water to Las Vegas and currently Lake Mead’s water level is dropping (Wockner, 2014). This supply makes up 90% of Las Vegas’ water resource (Tracy, 2014). The lowering water level elicits concern over how water will be supplied to Las Vegas, and Nevada as a whole, in the future. Las Vegas sits in a valley, a trough, with sediment layered in the trough from weathered bedrock (Laczniak et al., n.d.). Before groundwater pumping began in the valley discharge occurred primarily through “springs and evapotranspiration” and the estimated natural
Earlier in March 2014 the senior leadership of the Air Force, to include the Secretary of the Air Force, the Chief of Staff, and the Chief Master Sergeant of the Air Force, made a statement to all airmen. They stated that “being an Airman is more than a job, when we voluntarily raised our right hands and took an oath to support and defend the Constitution, we became members of the profession of arms”, they also said that along with our profession of arms we are given and accept a sacred trust given to us by the American people, that to be worthy of this trust we must “build our lives and shape our service on the foundation of our core values”, and that when Airmen fail to live up to our core values, the reputation of all who serve is tarnished” (letter to airman, Mar 2014). Recently, I was tasked to deliver a briefing for the J3 monthly training day. This tasking was a result of my negligence in updating a certain system that is vital to the J3 watch floor. My briefing, although filled with correct information and guidance, was also slaked with profanity and unprofessional gestures. Regardless of any circumstances that may have been the cause for these actions, the actions needed correction. Correction was given, which was responded to by more profanity and provoking actions. After I showed such disrespect to my non-commissioned officer in charge, he escorted me to my supervisor and my actions were made known to him. During this time I was still acting very contentious and disrespectful, making snide comments and standing with such contempt as if to say “are you done now”. This of course escalated into more serious action by my leadership which very well could have been avoided had I done my duty correctly in the first place. The...

A life with a healthy heart is something that is beyond wonderful. Unfortunately, many people of the world cannot embrace this feeling. Individuals all over the world deal with heart disease. 15 million and counting, heart disease continues to be the leading cause of death in the U.S.
Authoritarianism is defined as “expecting or requiring people to obey rules or laws, not allowing personal freedom” (Merriam-Webster). Democracy: “an organization or situation in which everyone is treated equally and has equal rights” (Merriam-Webster). Both sets of ideals, actions, and beliefs are ultimately decided by education. What is education and what does it mean for a person to be educated? If one thought of the traditional sense of education that consists of math, science, and language, North Korea, which holds a “Freedom House” score of 7 (the most authoritarian score possible) could seem to be the more educated country. While both France and North Korea have literacy rates of above 99% (World by Map), the education process is held to a much higher standard in No...
