Worlds environmental problems Essay Example for Free

Worlds environmental problems Essay Introduction Rational Based on the past experience in the area of environment and resource studies, the environmental problems such as the accumulation of heavy metals in water and sediment in the canal and river have been the major focus in the study area. The study shows that the major source of heavy metals that accumulate in water and sediment is industries. As a result, it motivates the researcher to choose the research topic about industrialization is responsible for the worlds environmental problems. This current research will certainly be useful for the researcher. It is because this research is closely related to the researchers future study, particularly in the area of environmental engineering. The analysis of research topic Industrialization and the worlds environmental problems are shown as the topic area of the research in the diagram. The research topic is focused on the relationship between industrialization and the worlds environmental problems. Therefore, there are two aspects in the topic which are industrialization and the worlds environmental problems. The purpose of this research is to take a position whether industrialization is responsible for the worlds environmental problems or not. Industrialization brings many problems to the worlds environment. As a result, it is definite to study the causes of worlds environmental problems which can be explained with three main aspects. These three main aspects are the aims of industrialization, the consequences of industrialization and the governments policies about industrialization. Moreover, it is certain to study the effects of these three causes on the environment as have been shown in the diagram. Therefore, it can be proposed that industrialization is responsible for the worlds environmental problems. The diagram below shows the structure of the analysis of research topic. Industrialization is responsible for the worlds environmental problems Data collection The research method The research covers four steps shown as following. Firstly, the research topic that industrialization is responsible for the worlds environmental problems is analyzed in order to find out the probable areas that the research should concentrate on and the information which should be presented. Secondly, the definition of key concept is given. It is that industrialization can be defined as using developed technology in order to change a process of production from small-scale to mass production. After that, based on the definition, research evidence such as examples and statistical data are collected and analyzed in order to support the argument that industrialization is responsible for the worlds environmental problems. Finally, the information is organized into three main reasons of industrializations responsibilities to the worlds environment which are the aims of industrialization, the consequences of industrialization and the governments policies about industrialization.

Critical Review The two sources by Martin Allenby and Toal focus on the topic area of energy resources which are classified as renewable and non-renewable resources. Moreover, the authors relate the amount of resources to the using of resources in order to make people have the awareness about the limit and decreasing of non-renewable resources. The authors also emphasize people to use renewable resources as alternative energy sources. It is believed that these two sources clearly present about the situation of using natural energy resources and show that it is time to do the researches in order to develop the quality and cost of using renewable energy sources. In the articles written by Martin Allenby and Toal, they both reveal that non-renewable resources are decreasing; as a result, people should focus on using renewable resources as the energy instead of using non-renewable resources. However, in the article by Martin and Allenby, the authors emphasize on presenting the information about non-renewable forms of energy that are finite resources (Martin Allenby, 1993, p.71). The authors report  that the most important sources of energy in the world today particularly in the industrial countries are the fossil fuels ( Martin Allenby, 1993, p.71). For example, oil provides 40 percent of the worlds primary energy consumption (Martin Allenby, 1993, p.79). However, oil is not a plentiful resource. It is estimated that oil reserves are around 2000 billion barrels but only haft of oil reserves has been found and 400 billion barrels have been used (Martin Allenby, 1993, p.79). There are around 650 billion barrels that have been left in prov ed reserves (Martin Allenby, 1993, p.79). Another example which is mentioned in this article is natural gas. The authors report that the using of natural gas is increasing because it is clean, cheap and easy to handle (Martin Allenby, 1993, p.82). However, natural gas is not renewable and it has a limited supply (Martin Allenby, 1993, p.84). Moreover, the authors mention to coal that although coal is non-renewable resources (Martin Allenby, 1993, p.88) and burning coal create the pollution (Martin Allenby, 1993, p.87), it is used in many kinds of industries and the major use of coal is in electricity generation (Martin Allenvy, 1993, p.87). The authors conclude that people are aware that the fossil fuels are finite and non-renewable; therefore, they have become to look at renewable resources as alternative energy sources (Martin Allenby, 1993, p.89). On the other hand, in article written by Toal, the author focuses on showing the researches that have been done in order to develop renewable energy and energy efficient technologies. The author reports that 70 percent of research work that has been done by The National Renewable Energy Laboratory (NREL) is about the supply-side energy technologies of photovoltaics, biomass and wind (Toal, 2001, p.2). According to Kazmerski, director of NRELs national center for photovoltaics at Golden (cited in Toal, 2001, p.2), after many researches about photovoltaic devices or solar cells have been done, photovoltaic devices or solar cells are cheaper and more efficiency than the pass. Moreover, Bull, associate director of science and technology for all of NREL, reports that NREL is doing the research about biomass energy (Bull, cited in Toal, 2001, p.3). It is believed that the cost of biomass will be cheaper in the future and biomass energy will be produced more than now (Bull, cited in Toal, 2001, p.4). Further more, Thresher, director of NRELs national wind technology center, presents that the problem in the past to produce electricity by  using wind is the cost of production was too expensive (cited in Toal, 2001, p.4). However, since wind turbines have been developed, the wind machines have become bigger, more efficient and cheaper (Thresher, cited in Toal, 2001, pp.4-5). The issues discussed in the sources have been considered as an important issue because decreasing and exhausting of non-renewable resources are going to be serious problem. It is showed that non-renewable resources such as oil, natural gas and coal are decreasing. They will be exhausted in the future if people still use much these kinds of energy. Therefore, these non-renewable resources should be conserved and people should use renewable resources such as solar energy and wind instead. Historically, non-renewable resources are the most important energy sources in the world. Currently, non-renewable resources are shrinking and renewable resources have been considered as the alternative. As a result, many researches have been done in order to develop the quality of renewable resources and reduce cost of them. In Martin and Allenby article, it shows that fossil fuels such as oil, natural gas and coal have been used by many kinds of industries even though they are finite and non-renewable (Martin Allenby, 1993, p.76-88). However, Toal reports that there is the organization in America which has been established in order to develop renewable energy such as photovoltaic devices (solar cells), biomass and wind (Toal, 2001, p.2). These two articles show that the authors have the consideration about the decreasing of non-renewable resources by trying to encourage people to use renewable resources instead non-renewable resources. It can be seen that using non-renewable resources will make these resources exhaust because non-renewable resources are finite. As a result, it is very important that people should focus on using renewable resources. It is clearly distinguished whether each author of these two articles is objective or not. The article written by Martin and Allenby is objective because the authors present the issue by referring to the international situations. Moreover, the authors use the statistic data to support their research such as distribution of the worlds known oil reserves by region (1984) (Department of International Economic and Social Affair, 1987, cited  in Martin Allenby, 1993, p.86). The article written by Toal is subjective because the author emphasizes on doing the researches about renewable forms of energy in order to use them instead of using non-renewable energy sources by The National Renewable Energy Laboratory (NREL). Even though the author refers to the other experts opinions, all of these experts are the people who work for NREL. For example, according to Bull, associate director of science and technology for all of NREL (cited in Toal, 2001, p.4), cost of biomass will cheaper in the future and biomass energy will be produced more than now. It can be seen that the article written by Martin and Allenby is objective, whereas the article written by Toal is subjective. However, the examples or evidence in these two articles are clearly presented because the authors present the data by using graphs and tables that are easy to understand. Although the examples or evidence that are used in these two sources are not current, they still can be used because some of them are general knowledge. On the other hand, some of statistical data can be used as the direction of change for the future. For example, non-renewable resources are finite; therefore, the amount of them can not increase. In contrast, they are decreasing because non-renewable resources have been used as the major source of energy. Therefore, it can prove that non-renewable resources are decreasing and it is time to develop renewable resources to use as the alternative of energy sources. Even though one article is objective, whereas another is subjective, these two articles are clearly presented about the situation of using natural resources to be energy. In both articles, the authors present the data clearly because all data are presented directly to support the authors argument by using tables, graphs, maps and quotations. For example, the article written by Martin and Allenby explains how each type of non-renewable energy sources such as oil, natural gas and coal formed (Martin Allemby, 1993, pp.71-88). In this part, the authors use the maps to show the areas that these non-renewable energy sources formed in order to make clear understanding about the areas that these energy resources formed (Martin Allemby, 1993, pp.71-88). Further more, the authors also present about the amount of each kind of non-renewable resources in order to support their argument that energy resources which are mostly used are finite by using tables (Martin   Allenby, 1993, pp.71-88). \The article written by Toal mentions the results of researches that have been done by The National Renewable Energy Laboratory such as the research about photovoltaic devices, biomass energy and wind turbines by using quotations and graph (Toal, 2001, pp.1-5). The evidence that Toal uses can show the possibility of using renewable energy sources. Thus, the evidence can support his argument that it is time to focus on developing renewable energy resources to use as the alternative of energy sources instead of non-renewable resources which are decreasing. Therefore, it can be said that these authors interpret data clearly in order to confirm their argument. Both articles are general study because the authors only want to explain some important points about energy source. Therefore, the authors conduct research in order to confirm their argument. However, in the article written by Martin and Allenby, the authors have conducted enough research because the authors use the statistical data to support each area that they mention. Even though all of statistical data that authors use are selected from one source, these data come from the exploration by using scientific method. As a result, these statistical data have the accuracy and they can be considered as the fact. Further more, the authors use these statistical data that mention to the international situation to support their argument. For example, the authors use the statistical data that show the distribution of the worlds known oil reserves when they explain that oil is finite (Martin Allenby, 1993, p.77). On the other hand, in the article written by Toal, the author has not conducted enough research because all of data and other experts opinions are selected from one source. Moreover, all of them only describe the situation of developing renewable resources in America. For example, the author refers to the cost and the efficiency of photovoltaic devises that they are cheaper and more efficiency than the past because of doing the research by NREL (Kazmerski, cited in Toal, 2001, p.3). It can be seen that Martin and Allenby have done enough research, whereas Toal has not done enough research. Therefore, it can be said that Martin and Allenby conduct their research more thoroughly in order to confirm their argument. Among the two sources which are reviewed, it can be clearly seen that the  article written by Martin and Allenby has practical suggestion because it is possible to use renewable resources as the energy. Currently, the cost of renewable resources is the limitation of using renewable resources to be the energy sources. However, it would be possible to decrease the cost. The authors suggest that the research in the area of changing the cost of renewable energy should be done in order to tend people to use renewable resources as the energy sources (Martin Allenby, 1993, p.89). It is because the renewable energy such as sun and winds are infinite (Martin Allenby, 1993, p.89). Further more, many renewable resources are the clean energy. Therefore, it will be benefit for the environment if people use renewable resources (Martin Allenby, 1993, p.89). On the other hand, in the article written by Toal, the author does not make any suggestion. However, it is not necessary to make any suggestion because the author only wants to present the important point which is about possibility of using renewable resources to be the alternative of energy sources. Further more the author only wants to emphasize that it is time to focus on doing research to develop renewable energy resources. Therefore, it can be strongly said that Martin and Allenby have made practical suggestion in their article because renewable resources can be used as energy sources, whereas in article of Toal, it is not necessary to make any suggestion. Among these two sources, in the article written by Martin and Allenby, the authors have not used other experts opinions to support in their article. It is because their article presents the general knowledge that has been proven by many researchers by using scientific method. For example, the authors refer to how non-renewable resources formed and the amount of each kind of non-renewable resource (Martin Allenby, 1993, pp.71-88). In contrast, the article written by Toal is well supported by other experts opinions through using the quotation of other experts opinions. Toal refers to the situations of using renewable energy sources such as cost and quality that has been researched by NREL (Toal, 2001, pp.2-5). For example, according to Kazmerski (cited in Toal, 2001, pp.2-3), Some 35 years ago, when I started in photovoltaics, these devices were used almost exclusively for satellites. A solar cell would cost about $300 to $600 per watt. Today, a solar-cell module such as you would put on your roof-costs $3 to $6 per  watt. And in the future, with the use of thin-film PV technology, we could see that cost drop by half. In addition, the efficiency of commercial solar cells- their ability to convert sunlight into electricity- has risen from 7% to about 15% to18%. Not only Kazmerrskis opinion, but also Bulls and Threshers opinion that Toal uses to support in his article by using quotation. It can be seen that quotations clearly support Toals argument about the possibility of using renewable resources to be alternative of energy sources. Therefore, it is certain for the method of quotation to support authors argument stronger through using other experts opinion. In conclusion, the review shows that energy resources such as natural gas, oil and coal are non-renewable resources and they have the limited supply. As a result, people should use renewable resources as the energy instead. In this review, two articles have been discussed in different six aspects. There are the historical and current significance, the objectivity of the writers, the interpretation of data, the thoroughness of treatment, the practicality of suggestion and other experts opinions. The authors of each article present their argument in different way. However, the authors of both articles use the examples, evidences or other experts opinions to support their arguments and present them clearly. More over, Martin and Allenby make their suggestion practically in their article. However, these two articles will be more effective than present if the authors use current data or current evidences and select data or evidences from various sources. The Analysis of the research The research is limited by three factors. These three factors are the types of information, the research focus and the time limitation. The first limitation is the types of information. The information used in the research is all secondary information such as the research results by Beder in the field of sources of greenhouse gases, the research results about the cost of investment in environmental protection by Mulhall. The information is conducted in order to support the argument. However, the information has not been examined closely whether it has exactly happened or not. The research focus is the second factor that limits the research. It is because this  research focuses only on the current situation such as the consumption of energy in order to use the energy in economic sectors such as industry and agriculture by Adler, Cazamias and Monack. This research does not cover any environmental situation before industrial revolution and during the beginning of industrialization. The final limitation in this research is the limitation of time. The research has to be finished with in limited time. Therefore, time is an important factor that enables the researcher to do in particular area. Many areas such as governments policies about environmental protection and reasons why governments policies about environmental protection can not control the environmental problems are not included in the research. In summary, these possible factors from the above are the factors that limit this research. Suggestions for future research As the research is limited by three certain factors, all suggestions are presented to overcome these limitations for the future research. The first suggestion is primary sources should be used in order to support the argument such as a survey about the cost of investment in environmental protection and monitoring sources of greenhouse gases. It is because using primary sources can tell about what has actually happened. For limitation of the research focus, the further research should be focused on other areas such as environmental situation before industrial revolution and during the beginning of industrialization. Moreover, the future situation about environment should be predicted. It is because the comparison of environmental situation in each period of time can show how serious environmental problems have been expanded. Therefore, the research area becomes deeper in terms of the relationship between industrialization and environmental problems. Finally, the suggestion on limitation of time is the future research should mainly focus on the past situation of environment, governments policies about environmental protection and reasons why policies about environmental protection can not control environmental problems. All of these suggestions will overcome three possible limitations and produce the deeper and more accurate research in the future.

Understanding Eskimo Science :: essays research papers

In Richard Nelson’s â€Å"Understanding Eskimo Science† a man, Nelson, traveled below the Arctic Circle in the boreal forest of interior Alaska were he lived, studied and interacted with a few native Eskimos groups during the mid-1960’s. Throughout the article Nelson provides an abundance of interesting and relevant information about Eskimo survival coming about through the understanding of one’s environment. Nelson’s best argument is the simple fact that these people have managed to survive in one the, if not the, harshest environment on the planet. There knowledge is useful, tested and true to the groups as this truly unique understanding of there world has permitted them to thrive well in these parts. Although the vegetation is rather scarce the Eskimo’s made due with a diet based mostly on hunting. But as we find out in the article Nelson describes how these people are well adapted to the art of hunting. The relationship between man and animal is described to be one of intricate understanding and respect: â€Å"Koyukon hunters know that an animal’s life ebbs slowly, that it remains aware and sensitive to how people treat its body†. The Eskimo people have accumulated a massive memory based archive of scientifically valid knowledge concerning the diverse workings of the landscape of Alaska. Unfortunately Nelson makes it all too clear that this knowledge is disappearing and he fears that once gone there will never again be such a deep link between man and land. On a side note, this arcticle also makes it clear that the Eskimo’s respect there elders and place them at the head of all that is important as there knowledge and experience is treasured. They are the teachers of there people and the identity of the Eskimo is reflected in stores of experience in the minds of elders like Igruk. Nelson is most obviously a rational man saying rational things, but as is often the case with topics concerning native people, this knowledge will probably be lost in time. This article makes one think about man as a hole. Are we truly happy in our jungles of steel? Have we not lost something of great importance, something the Eskimo people have managed to conserve through all these millennia. We have lost contact with the spirit of nature. We have lost it to a point where our scientist do not consider Eskimo science (general knowledge) as a valid enough foundation for

How Personal Can Ethics Get Essay

Discuss how personal differences and preferences can impact organizational ethics. Organizational ethics are ethics of an organization. According to (Butts & Rich, 2008) The ethics of an organization refers to an organization attempt to define its missions and values, recognize values that could cause tension, seek best solutions to these tensions, and manage the operations to maintain its values. In dealing with people from all walks of life and different morals it can easily put up a bridge, between ones values and beliefs. After all we are who we are according to the â€Å"Stages of Moral Development† developed by Lawrence Kohlberg who is best known in the field of psychology of ethical decision making and behavior. One’s own personal beliefs and principles can impact their work environment if they are trustworthy, exemplifies a positive attitude, work well with people (internal and external in the work environment), dependable, and etc. This type of person is someone who would be considered to have a great impact in an organization, because of the values and beliefs they display in the work place. Meanwhile a person, who is seen as rude, has a negative attitude (towards people in and outside of the work environment), lacks integrity, and lazy (always doing something upper-handed to get by), the chances of that person being the downfall of an organization is 80/20, due to the fact this person is someone who doesn’t value others well-being, because of the negative morals they learned. A person’s professional ethics are just an expansion of their learned individual ethics. Personal differences and preferences impact organizations all the time, which is why it is so important ethics, play a key role so that unethical behavior doesn’t go unnoticed. Discuss how organizational policies and procedures can impact ethics. Organizational policies and procedures can have both a positive and negative impact with regards to ethics. An organization may have a positive impact if policies and procedures are based on good business ethics.

Europeans saw the tribal lifestyles lived by the Africans in the 16th century. Regardless of the criticisms of Europeans toward the African civilization, Africans were already established as much as Europeans were. Most African villages were under a communal system in which everyone was under the impression that they shared their personal belongings and possessions with one another. Don’t waste time! Our writers will create an original "Europeans Saw The Tribal Lifestyles" essay for you Create order Moreover, European travelers observed the existing social hierarchy, religious and cultural practices, as well as slavery in African communities. The idea of an established slave system in Africa was used by Europeans against the worlds accusation for instigating the atrocious slave trade across the Atlantic Ocean. However, Slavery in Africa differed in the colonies in that African slaves in their home country were treated humanely and were given rights. Even so, the Europeans saw the Africans as perfect fit to enslave in the colonies which then led to the destruction, oppression, and extermination of African slaves. The colonists who established early settlements in the mid-Atlantic colonies attempted to impose forced labor on the Native Americans in the same manner Christopher Columbus had successfully done. However, the Natives were known to have a depleting population due to the diseases they developed and the harsh maltreatments they faced under the Spanish colonists. Most of them were also familiar to their own land, allowing them to easily escape when captured. Ultimately, they were willing to revolt against those who threatened their freedom and stability. For these reasons, the colonists were discouraged and sought for an alternative. To the colonists, the Africans were better to enslave because they did not know the settlements in the colonies and they were randomly chosen from one tribe to another. As a result, Africans struggled to communicate with one another. Eventually, Africans were torn away from their homes and a community of slaves in the colonies emerged as these trips proceeded, creating a bond of broken people who may have forgotten what their lives were like before they were taken as captives. Because of this, the colonists withheld more profits than they should have due to the large imports and cheaper exports of African slaves. Shipped in large numbers, the slaves soon occupied most of the southern colonies due to the high demands for labor in large farming communities, and where they eventually became substitutes for white indentured labor shortages in the northern colonies. Slavery began the moment Africans were torn away from their homes. Chained by slave dealers, sometimes one of their own, they were en route to the Americas in crowded ships in what was often called the Middle Passage. The slaves were shackled for the full duration of the voyage and were tightly packed in the ships deck; they were positioned in the ship where no one single person could move. During the six to thirteen weeks of the passage, Africans experienced seasickness, were exposed to heat and diseases since they were packed altogether and died out of hunger and thirst. While some slaves formed insurrections or revolts against the slave dealers, many of them committed suicide by jumping overboard. For most of them, it was easier to take away their own lives rather than to suffer for weeks in the Middle Passage and for years in the colonies. Although many of the slaves died during the Middle Passage, the traders and slave owners still managed to double their profits and repeated th e same process of collecting as many slaves in one trip. The doubled profits resulted to high and competing exports of slaves among the colonies but in turn took the lives and freedom of African Americans. The slaves who survived the Middle Passage were either transported to the Chesapeake and Southern colonies to work in plantations or used as substitutes for domestic labor in the English colonies. African American women were often chosen and purchased as domestic slaves. These slaves were tasked to do household chores including cleaning, laundry, and taking care of the children. Their masters had no choice but to live under the same roof as their slaves. In exchange for a shelter to live in, domestic slaves were often sexually harassed by their male masters; no law prohibited the wrongdoings of slave owners toward their slaves. Most white slave owners harmed their slaves if they were to disobey their commands. Slaves in the plantations faced worst circumstances. Plantation owners enforced them to work for ten hours under the searing heat without food to eat or water to drink. For instance, in South Carolina the slaves planted and harvested in rice plantations which were usually positioned in inland swamps, forcing them to work with damp and dirty clothing. In the sugar plantations, many slaves lost their arms, fingers, or hands due to the dangerous grinding mills which they used to crush sugar canes after their harvest. Others suffered from burns due to the continuous process of boiling juice from crushed canes to create sugar and molasses. More importantly, slaves who slowed down their work were whipped, scarred, or mutilated. Likewise, runaway slaves were branded to mark them as rebellious or identify them with their owners. All in all, field and domestic slaves suffered from the tedious work they had to abide by every day. The slavery in the Americas began with the lack of indentured servants and Native Americans and ended with the diminishing population and culture of Africans. Because Africans had less knowledge about the colonies and had subordinate defiance, they were easier to enslave. Few slaves endured the horrid circumstances and mistreatments of their slaveholders from the Middle Passage to the colonies and many of them died out of poor living conditions and harsh treatments on behalf of both traders and owners. Ultimately, the lives of African Americans were exchanged with bountiful profits accumulated by the colonists which then led to growing economies and in demand labor in the colonies.
