Stretching a total of about 3,964 miles, the Yangtze River has played a considerable role in the lives of Chinese citizens for thousands of years. Along with serving as a major form of water transportation and trading, Asia’s longest river is considered a key role in China’s agriculture and economic system. Where the river runs through Sandouping, one would find the Three Gorges Dam—the largest, and possibly the most infamous, dam in the world. Even though the Chinese government had intentions of using the dam to control flooding and generate power, the Three Gorges Dam has proven itself to be an environmental catastrophe for the Chinese. Even before the Three Gorges Dam was built, the Yangtze River was still considered to be a “polluted
There are nine dams in and directly leading to New York State’s Letchworth State Park. These dams have been built for a variety of reasons and affect nearly 400 miles of freshwater rivers in the Genesee River Basin of Western New York (Fish, n.d.).
Hoover, Glen Canyon, and the Three Gorges. What do these three things have in common? They are all man-made dams. Throughout the world, man-made dams affect the three pillars of sustainability. A legend of controversy surrounding these dams has created a unique background story, as well as shown the positives and negatives of these man-made wonders.
The one feature common to the Hoover Dam, The Mississippi river and the three gorges dam is that they all tried 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.
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.
Grand Coulee Dam is a hydroelectric gravity dam on the Columbia River in Washington State, built by industrialist Henry J. Kaiser It is among the most famous dams in the United States. The reservoir it created is called the Franklin Delano Roosevelt Lake. The reservoir is named after the United States President who seemed to love dams and hydroelectric power and who was involved with the project through to the final completion of the dam. The dam was built as part of the Columbia Basin Project as a way to irrigate the desert areas of the Northwest United States. The dam started during the 1930s as a public works project and finished toward the beginning of World War Two. The initial construction plan was reconfigured during construction for more height. Its height was determined by the point at which the water from the reservoir began backing up into Canada. The scope and size of the dam is hard to comprehend. It is over a mile long and taller than the Great Pyramid of Giza, in fact, all the pyramids at Giza can fit within the base of the Grand Coulee Dam. The dam is so large that a truck at the base looks like a toy, this creates some perspective into the dam's true size. When the dam was completed in the early 1940s it was the largest dam in the world.
In Southern China, the Yangzi River provides transportation and irrigation throughout China. The Yangzi River, also referred to as “China’s blessing,” rarely floods and creates a warm, long growing season. The land around the river is lush and ideal conditions to grow vegetables, fruits, and grains. In contrast, the Yellow River of the North is essentially opposite. The river is often referred to as “China’s sorrow.” The weather is cold and dry and it leads to harsh seasons with drought, flooding, and frost.
Over the years Glen Canyon Dam has been the spark for hundreds of debates, rallies, and protests. These debates have been going on for almost forty years now. The fact is that the dam created a huge lake when it was built, this is what bothers environmentalists. This lake is called Lake Powell and thousands of people depend on its tourists for income. The lake also filled up a canyon called Glen Canyon, some people say it was the most beautiful place on earth. The anti-dam side of the debate has its basis in the fact that Lake Powell is currently covering Glen Canyon. It was very remote so few people got to witness its splendor. This is probably the reason the dam was built in the first place, ignorance.
This extended essay will analyze the rhetoric of authors discussing the Glen Canyon Dam. These authors include: Jeff Rubin (The Place No One Knew), John McPhee (Encounters with the Archdruid), Russell Martin (A story that stands like a dam: Glen Canyon and the struggle for the soul of the West), and Jared Farmer (Glen Canyon dammed: inventing Lake Powell and the Canyon country). There are always two sides to an argument, one for one against.
One of China’s best successes has in turn been one of its biggest downfalls. One of the main problems is China’s greatest success which has been its phenomenal economic growth. This is one of the main drivers of the current environmental problems that the country faces. Factories dump pollutants into the air and water. It is difficult to see the Chinese government making the significant sacrifices required to improve their environment if it means slowing down their economic growth.
Beginning shortly before the turn of the last century, there was a noticeable trend towards the ambiguous in modern Brazilian literature. Writers such as Machado de Assis and Jorge Amado have both explored the use of the unstated and the forced compromise between extremes that have grown to be so crucial to the modernist movement. No Brazilian author, however, has mastered the compromise quite like João Guimarães Rosa, a man who was once described as not only leading, but preceding the reader "to a place where there is discord and cacophony under which there is a strange harmony…the third bank of the river…the land every soul craves for." In his collection of short stories, Primeiras Estórias (1962), Rosa pays particularly close attention to ambiguity as a main theme in Brazilian backland writing. First translated to English in 1968 under the title First Stories, Primeiras Estórias, and in particular, "The Third Bank of the River," is in many ways the defining work of the Brazilian short story.
Confusion, embarrassment, and guilt can all be found throughout João Guimarães Rosa's short story "The Third Bank of the River." Rosa forces the reader to analyze his words and delve deeply into the hidden meanings behind them. Upon first glance, a story unfolds of a father who seemingly abandons his family and chooses to live out the remainder of his life rowing a small boat back and forth along a river. There are circumstances leading up to this behavior, which new insight to the author's psychological meaning.
Nadav Kander’s photographic gallery Yangtze – The Long River catalogues the everyday living environment the Chinese live along the Yangtze River. Kander claims:
The Three Gorges Dam on the Yangtze River will probably be finished by 2009 and will be the largest hydroelectric dam in the world.
The proposed for Kaeng Sua Ten dam project has provoked controversy for more than ten years. Due to fierce objection from the locals, the government's aspiring aims to construct the dams in Phrae province's Tambon Sa-Iab may never leave the drawing board. The government declared that the dam was essential. It would reduce flooding, ease seasonal drought areas, and lead to agricultural development. Dams are a crucial component for industry and hydropower and attracting many local and international investors. On the other hand, the locals, fierce resistance of the project claimed that the project was ineffective and unsustainable. Furthermore, it would impair the ecosystem and livelihood of the villagers. They demanded for an effective precipitation in decision-making and conservation of Mae Yom National Park (Wongruang, 2012) . I strongly believed that the construction of Kaeng Sua Ten dam should be stopped as it is inefficient and unsustainable, it damage forest ecosystem, forest biodiversity, and livelihood of the villagers, as well as leaving little room for social justice .
Many people have already dammed a small stream using sticks and mud by the time they become adults. Humans have used dams since early civilization, because four-thousand years ago they became aware that floods and droughts affected their well-being and so they began to build dams to protect themselves from these effects.1 The basic principles of dams still apply today as they did before; a dam must prevent water from being passed. Since then, people have been continuing to build and perfect these structures, not knowing the full intensity of their side effects. The hindering effects of dams on humans and their environment heavily outweigh the beneficial ones.
