Three Gorges Dam
Director Owen Lammers calls it one of the "largest and most environmentally and socially destructive projects on Earth"(Maier, 1997). One of China’s oldest dreams is becoming its newest reality. Since 1914 the idea has arisen of damming the Yangtze River. China plans to do this with a 600-foot, cement wall which will take eleven years to complete and costs could rise to over 75 billion dollars. The dam is claimed to have many advantages for China and the Chinese. Three Gorges is expected to produce around one-tenth of the nation’s energy, without the use of coal, improving air quality. Also, the natural floods that occur with the Yangtze river will be stopped, supposedly saving thousands of lives in the future. The first thing needed to keep the project going is money, and many United States senators see this as a great opportunity for jobs, but it is also viewed as a good investment. Fortunately, the U.S. Export-Import Bank, (for the first time), "…denied financing solely on environmental grounds"(Giaccia, 1997). These advantages are easily outweighed by the disadvantages of this proposal; this monument threatens the environment, but construction will ensue.
If the dam is so beneficial then why is it that all public debate on the issue has been banned since 1989, even for "…scientists and specialists"(Faison, 1997). This has probably been done to slow the process of or eliminate any opposition that may arise to this project. There are a few questions or "What if’s" about the dam, such as "What if the dam collapses?" or "What if during a war or conflict a bomb is dropped on the dam?" and since the dam is built on many seismic faults, will earthquakes be a problem? Besides all of these questions, there are numerous facts that should dissuade any proponent of the dam to insist on its construction. The dam besides hurting the environment, will also "…displace 1.3 million people."(Giaccia, 1997). These people were not asked to leave, they were told, and many of them still have not been compensated for their trouble, but this goes deeper than financial burdens. Individual rights have been violated, the government simply forced these people off their land and out of their homes and this affects children, families and livelihoods.
Looking at the dam’s environmental harm specifically, it is clear that this project should immediately cause. "Environmentalists warn that sewage will back up and destroy the precious habitats for river dolphins, giant pandas and other rare animals.
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.
Another one of my reasons why building the Great Wall of China was not worth the costs is because many lives were lost. Building the wall was very dangerous. The would hire Han soldiers to work on the wall for two to five years. If people died while
The Keystone XL pipeline continues dividing the opinion of the people and being a controversial issue. The precious “black gold”, represents one of the main factors that moves the economy, nationally and globally. This extra-long pipeline will transport oil all the way from Canada to Texas. Some experts and the private oil corporation, who is the one in charge of this project, point to the benefits of this project, for example, will make the USA more independent from foreign oil, will create thousands of jobs and improve the economy. Nevertheless, are experts revealing how the pipeline is an unnecessary risk and will be negative for the environment, dangerous for the population living close to the big pipes, and long-term negative for the
Materialism is defined by Webster's Dictionary as "a preference for material objects as opposed to spiritual or intellectual pursuits" (172). Life in 2002 is very materialistic. I am a part of a generation that has been focused on "what we have." Materialism is something that I have just realized is an issue for me. Into the Wild and The Narrative of the Life of Frederick Douglass opened my eyes to how complicated materialism makes life. After completing the novels, I visited with my mother as she has had a different experience in her lifetime. I also interviewed my wife as she has a different upbringing from myself. All of this information has provided for a new perspective for me on materialism.
.... But this wall must be passable; it must have an opening that anyone can pass through. But the only people that will find the door through are the ones that are willing to be open themselves!” There are so many views, ideas, and aspects of wall due to its extreme complexity, culturally and archeologically. Everything can be linked to everything! This is the ultimate anthropological truth. The Great Wall is truly great.
In today’s world, people in general like to keep up with the latest things such as gadgets like the iPhone. They tend to spend an ample amount of time on their gadgets or whatever the latest item is instead of dedicating their time to the more important things. During family dinners, everyone is usually on their phones. People may prefer to spend a day at the mall instead of volunteering. High credit card bills can result from spending so much money on the new things rather than paying bills. The social pressure to keep up with these material items has an effect on quality bonding time which has an effect on money. Consumerism actually sets a person against oneself because of the never-ending mission to acquire material objects therefore people should not concentrate their religious faith in materialism.
Economy and materialism are concepts that come up every day in the life of Americans. Those who are not from America may think the way Americans live is strange and wasteful and they’d be right in their thinking that. Americans are consumed by consumerism and the need to buy things because there is always some new and improved version of what was purchased two weeks ago. Although it is said that Americans are too materialistic, the truth is that materialistic does not quite cover the near obsession with the latest and greatest that Americans have.
...hat materialistic attitudes are harmful to one's well-being. “The psychological perspective attributes the development of materialistic values to family circumstances that create stress and self esteem issues that promote materialistic values,” (Hung Vu Nguyen.) Many people in our culture attribute material goods to personal achievement. Truth rings true with Bertrand Russell’s statement “It is the preoccupation with possessions, more than anything else that prevents us from living freely and nobly.” Even at young ages children are competing and bragging to one another of who has more possessions. Past studies by Rindfleisch say that materialism developed over time as a response to stress due to family issues such as divorce, separation, and loss of loved ones. Materialism leads consumers to put a disproportionate amount of their resources into acquiring goods.
Water pollution has had devastating effects on the environment, which include irreversible effects on the oceans ecosystem. People often underestimate the importance of the ocean. They don’t realize how much damage pollution has caused to the ocean and the thousands of creatures that inhabit it. Earth is a huge place, but resources are actually very limited and will not last forever unless there is a balance. We must protect the resources we have in order for them to last into the next generation.
The Great Wall of China stretches about 5,500 miles long crossing deserts, mountains, grasslands, and plateaus. It took more than 2,000 years to build this incredible manmade structure. Many people died to build this wall. It displays the changes between the agricultural and nomadic civilizations. It proves that the superb structure was very important to military defense. It became a national symbol of the Chinese as a security for their country and its people. The Great Wall of China must be preserved at all cost because it is a historical symbol that made it possible for China and other nations across the world to prosper (UNESCO World Heritage Centre: The Great Wall).
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.
Some of the species being threatened by pollution include: dolphins, porpoises, penguins, sharks, and polar bears. B. Humans are also being affected. 1. Clean water is needed for good human and animal health, but as DoSomething.org states, over 1 billion people worldwide don’t have a means of getting clean drinking water, an... ... middle of paper ... ...
... everything is available to them for a price and society standards require them to buy those things for whatever price. We love the idea of buying the new stuff about buying the best and that is a sign of a society where goods determine self-worth. But we accept that and because we accept it is why we are referred to as an overly materialistic country. Worse of all, the details that back up the argument are all true. But we also have our standards. We are not overly materialistic, there are limits after all we just came out of a recession. People in American society take money very seriously because it can either make or destroy your life and what choices you make. America is a very materialistic society and it has to with how successful we are and that success with the country want of money, the country’s need of things give us our title as materialistic country.
This is a thought-provoking book about the pursuit of material goods. Kasser is not a preacher, but a scientist. He presents his evidence carefully, and concludes that materialism is a game not worth playing even on its own terms of promoting human happiness.
Individuals also learn to adopt materialistic values through social learning from family members, peers, and the materialistic messages that they are frequently bombarded with in television programs advertisements (Kasser et al., 2004). The materialistic lifestyle, According to Kasser (2002), is a process of acquiring material goods beyond the necessities to meet human needs. It is of high importance to the individuals to attain financial success, impressive possessions, an attractive image, and a replicable status. Materialistic people tend to use money as a mean of self-enhancement (Kasser et al, 2004). Similarly, Belk (1985) explains materialism as the importance a consumer places on the acquisition and ownership of possessions (Belk 1985) and the view that there is a ris...
