Environmental Issues Impacting Vietnam - Essay Example As such, aqua-cultural methods bring about nutrient loading of the so-called â€Å"grow-out† system in which the food leftovers of the aquatic creatures accumulate in the water causing turbidity, eutrophication, and sedimentation. Hazardous levels of dissolved phosphorus and nitrogen from excrements as well as the pharmaceutical and chemical substances used for developing aquaculture further pollute the body of water and are taken in by the fish which, by food chain, are eaten by men.[1] Additionally, when fish become stressed through grow-out settings in an aquaculture, disease and parasites emerge in transmission between organisms and those that escape inefficient net operations threaten to reduce genetic diversity. Because intensive farming is carried out in culturing shrimp, lobster, and catfish, the clearing of natural habits such as mangrove forests is designed to establish more farms and meet the demands of production in vast numbers. This, nevertheless, has led eventua lly to the salinization of aquifers and soils, making the freshwater reserves more saline and thus, not conducive for use in crops, human consumption, and certain industrial functions as they suffer from low freshwater quality and amount. Pertinent environmental agencies (government and non-government) account for recycling of carbon, phosphorus, nitrogen, and other wastewater nutrients into useful feed supplements and fertilizers. This way, loading of nutrients in an aquaculture may be monitored in order for the aquatic environment to remain in equilibrium with the materials that sustain it. Devastation of Forests by Aggressive Human Exploitation The exploitative approach of deforestation constitutes another issue which designates Vietnam at the height of environmental calamity. According to Do Thanh Hai of the Forest Protection and Management Division, â€Å"The illegal exploitation of forests is most common in natural forests, nature reserves and national parks in northern Dien Bien, Bac Kan, Yen Bai, and Lang Son provinces.† There were about 2,400 reported illegal cases of timber trafficking which indicates how substantial the rate of deforestation is as executed by poachers who have had the backing of some local residents despite the presence of the opposing indigenous minorities. [2] Like the rest of the world that has encountered the undesirable impact of denuding forests, Vietnam similarly experiences how the negative aspects of the practice reflect in unhealthy soil composition and lower capacity to resist floods and runoffs that erode soils to abnormal extent. It would take the Vietnamese a great deal of having to remedy global warming since massive logging implies higher concentrations of greenhouse gases in the atmosphere, given that only a few number of trees are available to absorb of such gases as carbon dioxide (CO2) to sustain their photosynthetic requirements. At anytime, concerned citizens of Vietnam may opt to complain or bring to pu blic notice any poachers / illegal loggers caught in the act. Though no significant efforts have been documented in reference to nationwide protest against deforestation, the Vietnamese may consider engaging more into campaigns that are ‘pro’ to conservation and preservation of forests. They can also think about being actively engaged in tree-planting activities at feasible regions of the country. Large companies that require timber as the main working component or raw material of their business must be encouraged to seek other alternatives so as to minimize the frequent cutting down of trees. Environmental Damage Brought by the Mid-20th Century War Moreover, the environmental ruins of the Indochina war during the period 1962 –

Argument final - Research Paper Example ilable medical remedies, and so many patients suffering from these diseases are made to endure severe and chronic pain, vomiting, difficulty in breathing, and other similar discomforts. They are often also made to endure such symptoms for days and even months before they eventually die. In the interim, they often reach the point of wanting to end their suffering and pain by ending their life. Lacking the strength and the means to end it, these patients turn to their physicians to assist them in ending their life. But legalizing physician-assisted suicide (PAS) is a dangerous step which is very much against the basic principles of the medical practice. With such a premise, this paper shall discuss and support the thesis that physician-assisted suicide should not be made legal. An important consideration in the assisted suicide discussion is the fact that committing it is against the basic principle of non-maleficence or of not doing any harm to one’s patient. The Hippocratic Oath which serves as the basic ethical mandate of the medical practice expressly prohibits physician-assisted suicide and euthanasia (Finlay, 2005). This oath declares that a physician should not â€Å"administer a poison to anybody when asked to do so, nor will [the physician] suggest such a course† (as cited by Demy and Stewart, 1998, p. 249). In the time of Hippocrates, assisted suicide and euthanasia were very much against the principles of medicine. In the current context however, assisted suicide and euthanasia are ideas which are new and different from the concepts of medicine and care (Walker, 2001). Those who support physician-assisted suicide and euthanasia also have different ideas on what it is to be a physician and what the moral boundaries of the practice a re. â€Å"It is also telling that the current public interest in PAS comes at a time when the palliative powers of American medicine are greater than they have ever been in the past† (Walker, 2001, p. 27). All in all,

The Melting of the Polar Ice Caps Research Paper

The Melting of the Polar Ice Caps - Research Paper Example Without a doubt, the earth’s climate has changed over the years. Though most of these changes could be attributed to variations in the orbit of the earth which lead to changes in energy from the sun that reaches the earth’s surface, current trends suggest that most of these effects are as a result of anthropogenic activities and processes over time. With the advent of technology, data collection and analysis are rarely inconclusive. This becomes possible through the use of satellites that go round the earth’s orbit in successions collecting a wide array of information on the earth and the ever dynamic climate. The study and analysis of this climatic data has always given evidence to the occurrence of global warming (Patterson 19). Rapid increase of temperature over time is an example. Temperature increase has mostly been experienced in the 1970s. The warmest 20 years got recorded to have occurred after 1981, while the warmest 10 years got recorded in the past 12 years. Though the 2000s experienced a stint of solar output reduction that led to a sharp solar minimum especially between 2007 and 2009, surface temperature kept rising. Most of this unprecedented heat gets absorbed by the water bodies. Lakes and oceans take up most of this energy with the upmost 700 meters of ocean water indicating warming of about 0.302 degree Fahrenheit in 20 years (Vardiman 12). Ocean acidification is also an indication of global warming to some extent. Due to the Industrial Revolution, the acidity of the surface water has risen by over 30 percent. This becomes largely attributed to the rampant emission of green house gases like methane and carbon dioxide into the air, which gets later taken up by the surface water. Recent trends have shown that the amount of carbon dioxide absorbed by the topmost layer of surface waters is increasing by over 2 billion tons each year. The concept of how green house gases cause global warming gets largely misunderstood. The larg est bulk of green house gases gets taken up by carbon dioxide. These gases do not prevent radiation from getting to the earth’s surface due to the short wavelength of light. Upon reaching the surface of the earth, some of the radiation gets absorbed by the earth’s surface and surface water bodies. What gets left of the radiation gets reflected back to the atmosphere. When solar radiation gets radiated back to the surface, it usually has a longer wavelength. As a result, it cannot penetrate the green house gases in the atmosphere thereby getting trapped. This leads to increase in atmospheric temperature (Maslin 99). Carbon dioxide atmospheric concentration levels have risen from an average of 270 parts per million (ppm) to the current 380 parts per million (ppm), a sharp increase of 30 percent. Methane gas also contributes to global warming. It is much lethal compared to other green house gases and exists in lower concentrations in the atmosphere. The melting of glacier s gets directly attributed to global warming. Though melting of glaciers is a natural process, the rate of glacial melt has been increasing rapidly. The fresh snow that gets formed is not adequate enough to replace the rapidly melting snow. The size of the glaciers keeps reducing. As surface temperatures keep increasing, it is only natural that the

Light in the Cave Essay Example | Topics and Well Written Essays - 500 words - 11

Light in the Cave - Essay Example The view from halfway up the hill was spectacular. The impenetrable darkness of the cave had vanished as it looked illuminated. I wondered why. I slurped down hot coffee from my flask. It was soothing and I felt at peace, but my friends appeared restless. Suddenly I could see the green all around me and the glimmering hollows in trees. Sun’s rays were filtering through the trees that towered high. The view of the river flowing down the gorge on a clear day was terrific. The waters glistened in the sun. I had been oblivious to the natural world around me. Cold breeze from the riverside was comforting. The sound of soft rustling of the leaves and birds singing from a distance made the day more pleasant. My friends became animated instantly when I became ready to continue the climb. The climb was difficult but thrilling. I hopped over logs and readily crawled under bushes but never did I feel sick or tired. But my friends wanted to keep me behind them. We soon spotted the path th at wound up in the cave. The opening was too narrow to let any light in. I was curious to explore but my friends took me aside for a picture of a cliff nearby. It was still midday but cold near the limestone cave. The outer walls of the cave were smooth in some places but rough in other places. As I was standing with my back to the cave looking down the ravine, I felt a touch on my back. What a surprise it was! They were my two other friends. They had lit up the cave with firewood and candles. They gave me the best surprise on my birthday.

Students Preference of Theory or Practical Teaching Methods in Essay

Students Preference of Theory or Practical Teaching Methods in Orthodontic Postgraduate Education - Essay Example Due to the significance of the projected theme, an educator from New Zealand, Neil Fleming, designed a survey called VARK (Visual, Aural, Read/Write, and Kinesthetic) in 1998. The purpose of the study was to evaluate the most preferred teaching technique of dental undergraduates and to illustrate any important distinction amongst the group of students. 31,243 respondents were interviewed regarding VARK preferences. The outcome of the research revealed that there were major divergences in students’ preferences for a particular teaching style. Overall, dental students preferred practical (kinaesthetic) learning to theoretical (aural) learning. The distribution of the scores also demonstrated preference for teachers who adopted well-planned practical teaching styles and assisted student note-taking throughout the teaching sessions. This case study will consider how these practices have impacted on teaching practices within the field of dental education. The paper will also report the outcomes of a small-scale survey of learning preferences of postgraduate orthodontics students and make recommendations for future teaching practice. Table of Contents Introduction 4 Problem Statement 5 Literature Review 6 Research Methodology 10 Data Collection Process 10 Distributed Questionnaires 11 Data Analysis 12 Validity and Reliability of the Case Study 12 Results 12 Discussion 15 Conclusion 18 Introduction The most important challenge facing dental instructors is the improvement in the quality of learner experience within the programme of study and educational surroundings. In undergraduate dental education, informative and scientific teaching is compressed into a span of four years sometimes even less (Bertolami 2001). This time span includes both theoretical and clinical practice which is a prerequisite to complete for successful graduation (Robotham n.d.). Although the incorporation of scientific approaches in the field of clinical practice is a fundamental aim of a ny dental course, learners often recognise that the secret for success in training is to pass the science classes by adopting rote learning and memorization approaches in addition to understanding the significance of this education when put into practice (Jordan, 2005). Bertolami (2001) has suggested that one of the most important reasons why students get frustrated with their programme of study was the lack of correspondence involving the learning (content) and the instruction delivery (form). While a considerable number of dental students had a preference for various learning techniques, most relied almost exclusively on the lecture as their primary means of information delivery. Teaching topics using lectures can be essentially passive for the learner and didactic approaches support rote memorization and note-taking (Biggs, 2003). It is essential for dental teachers to recognize that students differ from one another and what oftentimes differentiates them is their diverse approac hes to learning and knowledge retention. Adhering to all these factual revelations, this case study explores the preferred teaching technique of postgraduate orthodontic students at King’s College London orthodontic program using questionnaires as the method for data collection. This research question will serve the purpose

Dead Poets Society Essay Example for Free

Dead Poets Society Essay Dead Poets Society made a huge impact on how I see things now. I secretly branded Mr. Keating, as the Epitome of teaching, every students dream is to find a teacher like Mr. Keating. Eventhough his teaching style is unconventional, you would really learn something. Hes not like your typical teacher who teaches by the book, because for me, Mr. Keating IS the book. All his lectures are inspirational, he teaches things that would not just help you academically, but also emotionally. He reminds me so much about my Highschool history teacher, a very father-like person, very comical, easy to hang with and lastly he encourages us to pursue our dreams, even though our dreams are impossible. Mr. Keating and my highschool teacher made me realize that there are no limits when we talk about achieving what we want and reaching for our goals, the only hindrance would be ourselves, the fear of not succeeding. So that in the end, we would have little regrets or non at all. I think that its one of the many factors that led me to put Dead Poets Society as one of the must-watch movie list for me. At first thinking outside the box was such a cliche for me, but after watching it, I try to apply that idea to everything I do. This story is very suitable for us, teenagers. Who are currently in that state where we are still confused of what we really want for our future. Add up the nerve wrecking peer pressure, love, parents, homeworks, proffessors, organizations and the like, which contributes to our decisions.
