Light Pollution Our Vanishing Night Essay Example

Light Pollution: Our Vanishing Night Paper Nowadays, we have engineered the night to receive us by filling it with light. Nevertheless, this engineering comes with serious consequence, that is, light pollution, also known as phytoplankton or luminous pollution. This is a form of environmental degradation, which results from the excessive artificial lightings. Its sources include street lamps, neon signs, billboards, offices, and illuminated sporting venues. Instead of directly lightening objects, these artificial beams refract and scatter around everywhere unexpectedly. Hence, they not only obscure the starring night but cause damage to both our environment and human bodies. Therefore, light pollution is not even more a scientific issue to experts but a global problem to everyone. According to the International Dark-Sky Association (IDA), this environmental pollution can be classified into four types: light trespass, over- illumination, glare, and light clutter. The first type is light trespass, which occurs as unnecessary light enters ones property. When an intense beam outside causes sleep deprivation, this condition can be called light trespass. For instance, Hong Kong has a serious light trespass problem due to countless luminous ornaments of skyscrapers. Despite some 30 to 40 citizens annually complaints about light abuse, Hong Kong still ignites the night sky to demonstrate its prosperity. The second type is over-illumination, which stems from the excessive waste of light. Improper lighting designs in the workplace, inadequate lighting maintenance, and 24-hour commercial advertisements all contribute to over-illumination.

S. Department of Energy Source suggests that some 30 to 60 percent of energy is wasted by commercial advertising uses, two times than average U. S. Residential consumption. The third type is glare, which can be further divided into three classifications. First, blind glare describes an effect caused by staring into the Sun, leading to completely blinding and temporary or permanent vision deficiencies. Second, disability glare leaves significant reduction in Sight abilities by oncoming vehicle beams, or refracted glow in the fog as well as reflections from the printed. Third, the discomfort glare dose doesnt induce a dangerous situation, though it is irritating at best. The last type is light clutter, excessive groupings of lights. Clutter may generate confusion, distract from obstacles, and potentially induce accidents. For instance, the poor-designed street lights distract drivers and cause injuries. Besides, clutter may present a hazard, specifically in aviation environment. For instance, aircraft collision avoidance signals may be confused with grouping commercial lightings. Intriguingly, few know that light, a powerful biological force, influences not only human but both plants and animals as well. Plants acquire light not only for energy supply but for the induction of flowering. Each species has its specific ecological optimum curve, which describes the relationship between light intensity and growth. Outdoor lightings on plants result in abnormal individuals with delayed loss of leaves or accelerated branch growth. To the plants near street lights, they even have production in second bloom in autumn. Similarly, light pollution induces adverse effects on animals. It may disorient animals and disrupt their biological rhythms, which are related to the alternation of day and nights of the seasons. As National Geographic Magazine mentions, fewer and fewer of nesting sea turtles, which show a natural predisposition in the dark, lay eggs on sandy beaches. Their hatchings, which gravitate toward the more reflective sea horizon, find themselves confused by artificial lighting behind the beach. In England, some swans even put on fat more rapidly than usual for wintering and migrate to Siberian early. Since long artificial days induce early breeding, a wide range of birds shuffle their migration schedules. Under the long- term influence of light pollution, nocturnal mammals including desert rodents, fruit bats, opossums, and badgers forage more cautiously because they have become easier targets for predators. As for other creatures, we also have a genetically light-determined clock to control the day-night rhythm in the secretion of melatonin, which in turn affects the sleeping-waking rhythm, the movement rhythm and our brain activities. Disturbances in the day-night rhythm can have physical and psychological effects, such as jet-leg. Overall, changes in light level are like the alteration of gravity. It destroys the balance in our ecosystem. Since light pollution triggers serious environmental problem, issues on how to reduce it become vital and are discussed radically. The Hong Kong Night Sky Brightness Moon tutoring Network (INS) considers the rule of thumb for reducing light pollution is using lighting reasonably: do not set up unnecessary lighting and turn off lights which are not in use. Simply turning if the light when we leave a room can achieve the target. Other approaches include reducing as many useless outdoor lighting as possible, modifying the existing lightings into dark-sky friendly devices, and choosing astronomical- friendly lighting sources. For government and organizations, turning off the neon signboards at midnight, and reducing decorative lights of commercial buildings are all possible approaches. Take Japan as a demonstration. In 1996, Ministry of the Environment guided Japanese to turn off all lightings during the coming of comet Haystack. Besides, saving energy and reducing eight pollution can both be achieved by turning off useless lightings. The Earth Hour campaign in Sydney, for example, successfully assembles two millions people to turn off their lightings for an hour at night. It not only results in 10. 2% of reduction in energy consumption but promotes the message of preventing global warming at the same time. With efforts spreading around the globe recently, more and more cities and even entire countries have committed themselves to reducing light pollution. To sum up, light abuse not only induces problems for astronomers but impacts our daily lives. Living in our own making glare, we cut ourselves off from the light of the stars, disrupt the biological rhythms of day and night, and harm the ecosystem. Whats worse, we gradually neglect the treasure that heaven offers at night- the astonishing galaxies arching ahead. In a very real sense, light pollution causes us to lose sight of our true place in the universe and to forget the scale of our being. While our planet will likely never return to its natural state of darkness, we still can make efforts to help decrease over-illumination.

My Paper essays

My Paper essays In the novel The Partner, John Grisham uses several literary techniques to present the thrilling story of Patrick Lanigans struggles with himself and his life. The story is told in third person point of view so that the reader can receive the full effect of the story. Everyones insight into the trial and Patricks disappearance is shared by the omniscient narrator. The setting is also ever-changing which gives the reader insight into what is happening to each person during the trial. The book jumps scenes to share the outlooks of all the characters. Grishams strong grasp on what the reader needs to know to stay involved in the story shines through this novel. The beginning of the novel the narrator is explaining Patricks life in Brazil. There is really no description of how or why he is there. Then his capture is explained and the reader is opened up to the rest of the characters and their relations to Patrick. They put Patrick at the end of a wing on the base hospital. His was the only room with doors which could be locked from the outside and widows that wouldnt open. The blinds were closed. Two military guards sat outside the hallway, for whatever reason (Grisham 60). This description is taken from right after Patrick was captured and brought back to the states. The narrator here begins to slowly reveal the reasons behind why Patrick did what he had done. He sat low, his shoulders sagging, chin down, no pride here. He did not look around because he could feel the stares from every direction. Sandy put his arm around his shoulder and whispered something meaningless (Grisham 176). With these elements Grisham proves yet again that he has the superior ability to pull literary elements together to keep the reader interested. He uses the third person omniscient narrator and the constant change of scenes to allow the reader to be aware of what is happen...

The Development of Modern Art Essay Example | Topics and Well Written Essays - 2000 words

The Development of Modern Art - Essay Example This paper will discuss five of the best artists in the Contemporary period. Each of these artists will be analyzed in terms of their inspirations, styles, and techniques that they have applied to their works; works of which have contributed to the development of Contemporary Art. The list of contemporary artists includes Jackson Pollock, Willem De Kooning, Andy Warhol, Jenny Holzer, and Kara Walker.Upon the onset of the Modern Period, Jackson Pollock is one of those who had staged a significant feat in art development. Pollock, considered as one of the greatest contemporary painters in American art history, was part of a period where the Modernist Movement of 1920 was slowly transformed into the Post-Modernist Movement of Contemporary art history. In the New World, Pollock was known as an important member of a group of artists called the New York School. The New York School, more of a unified and collective artistic idea rather than a concrete institution, was popularly known as the Abstract Expressionists (Getlein 497). It was in this influence that Pollock acquired his unique style unto his works. His art established a new kind of visual that many had not seen before. In line with the Abstract Expressionists, the artist derived a direct influence from Surrealism. His technique showcased automatism and focused on the aesthetic powers of the unconscious. Being a painter of the mentioned genre, Pollock always exhibited large scale works in the literal sense. He used huge canvass sizes – this was to take his audience into the very essence of his paintings. The emphasis on huge painting canvasses is an essential part of Abstract Expressionists in order to highlight the effect of the entire piece (Getlein 497). The bizarre characteristics of the artist’s works bring out the very sense of post-modernism in his style. The perfection of his â€Å"drip technique† (Getlein 497) brings out the chaos ever present in his works. Yet, amidst this chaos, order, and beauty emerges as the by-product of Pollock’s hard work. This trait of â€Å"order out of chaos† is the true and sole criterion of good post-modern artwork (Libby).

Overcoming Shyness Via Writing Essay Example | Topics and Well Written Essays - 750 words

Overcoming Shyness Via Writing - Essay Example This granted me the ability to edit my thoughts and create much more informative or effective thought patterns that I often translated into effective verbal speeches. More importantly, the exercises and assignments in this course gave me an opportunity to improve myself as an analytical writer. That is because the exercises and assignments demanded that I have a thorough understanding of the topic offered up for discussion. As a writer, this class helped me improve my brain functions as well as my written and spoken speech skills. I had no idea before attending this class that there were so many different writing styles available to people. Oftentimes, I would just use the normal, everyday practice of writing notes or using text messaging when communicating with others. Through this class, I learned how to express myself through the written word in different styles. Which I will admit, made me seem like a more interesting person than I actually was. I also learned that using different styles for different occasions signifies a high sense of respect and value that one has for the person I am communicating with. Not being a native speaker of the English language, I will have to admit that the topics being discussed in class, and assigned for the written assignments were somewhat alien to me. That unfamiliarity proved to be a problem for me as the class progressed because I needed to spend quite some time familiarizing myself with the topics up for discussion. However, I will admit that this challenge also proved to be beneficial to me because it helped me improve my writing styles and skills. I learned how to write in a specific style depending upon a specific writing format and also the kind of information that I needed to present.  

Crowd Dynamics & Management in an Event Essay Example | Topics and Well Written Essays - 2000 words

Crowd Dynamics & Management in an Event - Essay Example As the discussion outlines, major events have happened in the world where issues such as stampedes lead to death and injuries, or people suffocate due to congestion and commotion. This study will elaborate on effective crowd dynamics and event management by evaluating the Hajj, an annual Muslim pilgrimage to Mecca which attracts millions of people. In 2006, a stampede led to the death of over 340 people. Since the first events were organized about 2,000 years ago, they have been increasing in number by the day owing to the effect they have on our lives. They affect our political, environmental, economic, social, and cultural aspects. An event can have negative and positive impacts on the stakeholders and host communities, and that has made understanding of crowd dynamics and event management an important part of events. Today, events are increasingly researched and well documented to optimize their benefits and enhance their outcomes. One of the biggest challenges to crowd management is that minor factors such as bad behavior, substance abuse or criminal behavior can alter the agenda of an event and lead to unintended consequences. An event manager should therefore be equipped with skills to predict and come up with measures to mediate in the event that an unintended occurrence emerged before, during, and after an event. To elaborate how effective crowd management should be structured, the following study text will highlight the causes of fatalities and injuries at the 2006 Hajj where 340 people died and 1,000 injured. Following these, crowd reactions to situations and environments at public events will be discussed with regards to crowd management and control. In January 2006, pilgrims at the Mecca Hajj pilgrimage event numbering millions went rushing through the city streets towards al-Jamarat, three large stone walls made of stone which represent the devil.  

The Death Penalty Is A Necessary Evil Essay -- Pro Capital Punishment

The death penalty is a necessary evil that has a positive effect on society today. It is an effective deterrent of crime as well as a safeguard for society. It also helps to keep order in our cities. It is a just and effective punishment for those who have committed crimes heinous enough to deserve death. The death penalty is not a new idea in our world. Its origins date back over 3,700 years to the Babylonian civilization, where it was prescribed for a variety of crimes. (Capital Punishment p.10). It was also greatly used in the Greek and Roman empires. It continued into England during the Middle Ages, and then to the American colonies where it exists still today. In the colonies, death was a prescribed punishment for crimes such as: murder, rape, arson, and perjury. In America today, the main crime deserving death is obviously murder. (Capital Punishment p.11-15). Does the death penalty truly deter crimes and murder? This question is at the heart of a heated political controversy over the punishment. Opposers to the death penalty say no because of the large amount of people on death row today. They also say that states that have the death penalty have a higher crime rate than those that do not, and therefore it is not effective and somewhat contributes to the problem. (http://www.rit.edu/~wwl2461/cp.html). I must point out though that states that have the death penalty are usually highly urbanized areas that most likely will have high crime rates because of the large population. Rather, in rural states there is no need for the death penalty because the population is most likely low and scattered throughout the region. States that practice capital punishment do so because of high crime ra... ...most effective means of crime deterrent as you can see. It not only punishes those who commit the crimes, but also prevents future crimes by scaring the would-be murderer with the consequence he would pay for his actions. It has proven effective throughout history, and will hold strong through the ages as long as people continue to be corrupt and commit crimes.
