A Clean, well lighted Place

A Clean, well lighted Place The short story â€Å"A Clean, well lighted Place† has been written by the author named Ernest Hemingway in the year of 1962. The story is basically a narration of different stages of life where the interest and thought process of people changes with time. Age is the biggest focus line of this story as people’s thought process changes with the growth in age.Advertising We will write a custom essay sample on A Clean, well lighted Place specifically for you for only $16.05 $11/page Learn More The author had illustrated different stages of human life with the help of illustrating characters of old waiter, young waiter and an old man at the cafà ©. This paper evaluates the similarities and differences in the traits of all three characters. The author had illustrated the younger age of human’s life to be full of excitement. The author has portrayed the character of the younger aged waiter as a young human who has his short terms goals. The a uthor claims that the young waiter did not really felt considerate of the older persons around him. To the young waiter, older people are filthy and clumsy who have nothing better to do in life (Hemingway). In the story, the author had described the traits of younger waiter’s personality as impulsive, inconsiderate of older people, focused to a conservative vision of sleeping with his wife and one who had no idea how death could come to his life in his later years of older age. I have a wife waiting in bed for me (Hemingway 28). The second stage of human life has been projected with the help of character of an old man who stays in the cafà © till late night to drink. He does not spill a single drop of liquor on the counter and when he leaves the bar, he walks with dignity instead of unsteady walk. The older age of the man had been regarded to a stage where there are no hopes left but the fear of darkness at home (Hemingway). The darkness had been used as a symbol of death. S taying at the cafà © for longer hours helped the older man to escape from the fear of darkness. The cafà © was well-lighted that had been used as an escape from the darkness. The light is very good and also, now, there are shadows of the leaves (Hemingway 62)Advertising Looking for essay on american literature? Let's see if we can help you!

The young waiter asked him about the old man who stays for loner hours at the cafà © late night. I wish he would go home. I never get to  bed before three oclock. What kind of hour is that to go to bed? (Hemingway 8) In reply to the question of the young waiter, the older waiter answers from his experience stating that older stage of life is full of fear of darkness (death). The older waiter states that the older man was in a progression towards old weary day s that ends with death (Hemingway). Through the above analysis of the traits of the three characters of the story A Clean, well lighted Place, it comes to our understanding that the old man was in a progression of an older age and had similar personality traits as the older waiter had. The younger waiter had been projected as a different human who is in his younger age and does not understand the fear of death and the need of light as an escapee in the older age. Hemingway, E.

Proving the lens formula Essay Example

Proving the lens formula Essay Example Proving the lens formula Essay Proving the lens formula Essay When light passes from air to a denser material it slows down. In a concave lens the light has to travel further through the middle then through the sides. This has the affect of pushing the waves back in the middle and forward around the edge therefore effectively adding curvature to the wave. A similar thing happens when passing through a concave lens but obviously vice-versa, taking away curvature of the wave. The curvature that the lens adds or takes away is the Power of the lens, measured in dioptres. P=1/f, P is the power of the lens and f is the focal length. The focal length of a lens is the distance from a lens to its focal point, which is where the image of a distant object is formed. The shorter the focal length the more powerful the lens. The following formula is what I am going to attempt to prove that it is valid. It is used to give the focal length, and hence where the image is focused. 1/v+1/u=1/f Where v is the distance from the lens to its focal point, u is the distance from the object to the lens and 1/f is the power of the lens. This follows from the above, the power shows how much curvature is added to the wave. As a wave moves further away from an object the curvature of it decreases. This formula may also help me with my progress, as I can use it to calculate the magnification of the lens. m=v/u (when in focus) Where m is the magnification, v is the distance from the lens to the image and u is the distance from the lens to the object. The further away the image is from the lens the lower the magnification, and the closer the image is to the lens the higher the magnification. Hypothesis The lens formula for a convex lens valid. Apparatus I will use the following equipment during me experiment. A Convex lens and lens holder Small convex lens used to focus the image on the screen. Small plastic holder used to keep the lens in place. A Metre rule Will be used to measure both the object distance (U) and the image distance (V). It has millimetre units, although large and hard to take a precise measurement in mm. A 30 cm rule Will be used to increase the accuracy of the measurements, where the metre rule proves difficult to use to get an accurate result. A Small screen Flat white screen on a stand, used for the image to focus on. Image distance measured from the front of the screen. A Light source (Mains or Low Voltage) small Lamp, 40-watt bulb. Used to emit light and is part of the object. A wire mesh on a stand Used to create a clear, sharp focus-able image that I can take measurements from. Placed in front of the light source. Jack Webdale 02/05/2007 Page 2 Most of the apparatus I will use are self explanatory due to the background information. I will use the Wire mesh on a stand as part of the object, as I am satisfied that it will be easy to produce a clear, sharp image with it. If I was to use A light bulb with text printed on it, it may be harder to get a clear image as if I used ink, it may smudge or become blurred due to the heat of the lamp. I have also chosen to use a 30cm rule as well as a metre rule, as the metre rule may be inaccurate or cause problems when trying to measure to mm. A 30cm rule could be used to do this easily and to a better degree of accuracy. Prediction I would choose to predict that the formula is valid. Avoiding the fact that people have used the formula for years, especially opticians, and I gather it must work as they still use it! However, my task is to prove that it works. The diagram below shows what occurs when light travels through a converging lens. It shows where the focal points image and object distances are represented. Due to the proportions of the diagrams I have studied, it would seem logical that two reciprocals added together would produce a reciprocal which its decimal value would be less, which confirms the diagrams. Therefore, I believe that my experiment, if done accurately, should prove that the lens equation is true. Diagram of apparatus Consideration of the variables This Experiment relies heavily on accuracy of measurements and distances. Therefore, it is imperative that these are not affected while measurements are taken. I will take 2 measurements of Jack Webdale 02/05/2007 Page 3 Each required distance to ensure I should not have made an error. Ideally, if I would have time, I could do an average of results for one distance to ensure a reliable result each time. However, I feel checking twice, taking the distances where the image appears focused, and taking a middle value, will give reliable results. Another Variable that could affect the point where the image is focussed is exterior light not emitted from the object (lamp and mesh). Therefore, I will compose my experiment in a dark room, so that sunlight will not affect the image, and this should also help me to get a clearer focus of the image on the sheet. I will stick all apparatus to the bench when they are not being used, so that the non-variables are not affected or altered. Method Before I begin the real experiment, I have chosen to perform a preliminary experiment to discover a suitable range of distances I will get results from. I will also have an idea of the power of the lens, so I can judge its minimum and maximum distances to get a clear image on the sheet. To do this I will set-up the apparatus as shown in the diagram of apparatus, And I have chosen to make the Object and the lamp a constant position, due to the wires etc and difficulty of shifting it about all the time. Therefore, the Lens and the image sheet are the elements that I will move to focus the image. Preliminary research I began with a crude test, to get an approximate result for the focal length of the lens. I simply got a piece of paper, put it against a ruler, and with the lens; I placed it in front of a window, and focussed the image on the paper. I then had a measurement of approximately 15 cm. This would help me greatly in my experiment, as it would indicate immediately any results way off the mark, considering the variables and errors. I then also set up the apparatus as shown in the diagram, and used them to determine what distances I would use in my experiment. I placed a metre rule on the bench, and put on one end, the screen that the image would focus, and at the other, the object. I decided that I would not exceed this Object to Image (U V) distance, as measuring over a metre would cause problems, as I would need to have to metre rules, increasing the chance of making the results inaccurate. I then discovered how close I could put the lens to the object, until I could not get a focus on the screen (Where The focal length equals the object distance, and the image distance = ?). This was in between 13-18 cm for the object distance. Preliminary research Summery Part 1 * Collect all of the equipment displayed in the diagram of apparatus. * Check that the lamp works, and that the lens is not cracked or dented. * Place the lens on a flat surface, facing a window so that light from outside travels through the lens. Place the screen at the opposite end, so that it looks similar to the diagram above, but using the outside as the image. Move the screen until an image (Real, inverted) is focussed on the paper. * Measure the image distance, using a 30 cm ruler. (This is the approximate focal length). Part 2 * Collect all of the equipment displayed in the diagram of apparatus. * Check that the lamp works, and that the lens is not cracked or dented. * Set-up the equipment as shown in the diagram of apparatus, placing the object at one end of the metre rule, and the screen at the other (this is the maximum object to image distance). * Move the lens close to the object, and experiment with the lens and the screen until it is Jack Webdale 02/05/2007 Page 4 Impossible to get a focussed image on the screen. * Find the bounds which this occurs, and record the results (This is the area where the focal length is approximately the same as the object distance). There is no need for a table of results for this preliminary experiment, as not many results are taken, they are merely to give an idea of the expected results in the real experiment. Real Experiment * Collect all of the equipment displayed in the diagram of apparatus. * Check that the lamp works, and that the lens is not cracked or dented. * Set-up the equipment as shown in the diagram of apparatus, placing the object at one end of the metre rule, and the screen at the other (this is the maximum object to image distance). * Turn on the lamp; line it up with the mesh so that the lens, screen and the object line up against the metre rule. * Keeping the Screen and the Object stationary, move the lens up and down the metre rule until a clear, focused image of the mesh can be seen on the screen. * Measure the object distance to the lens, using the white mid-point line on the lens holder as a marker, then measure the Image distance, using the front of the screen as the marker. Use the 30cm rule so that the mm can be measured as accurately as possible. * The lens can move around 5 mm and still produce a clear and focussed image on the screen. This is merely due to the sensitivity of our eyes. For the following results, keep the object stationary, and move the screen 10 cm down the metre rule, decreasing the distance to the object each time. Measure the distances. For the Image distance, you will need to record two results, where the image beings to lose focus between the 5mm focus gap. These results can be used to obtain a midpoint, where the real focus is occurring. * Repeat this so 8 records have been taken. For each, be-aware of the results been recorded, and be aware that the focal length is approximately 15mm, and repeat any result that appears irregular. * As the experiment goes on, eventually a focused image will be impossible to obtain. This is where the image distance is equal to the focal length. You should not try and record results at this point and beyond. Table of results example My table will take this form: U (object distance) cm Min. V (Image distance) cm Max. V (image distance) cm Avg. V (image distance) cm 1/U + 1/V = 1/F F (Focal length) cm . . . . . . Risk Assessment All things considered, there are little risks presented with this experiment. I feel confident no special precautions need to be taken to ensure the safety of people partaking, or working near the experiment. The are few dangers which in extreme circumstances could cause a problem is the Light bulb. First because of the heat and the risk of burning a hand, which can be avoided by using a metal cover, not touching the bulb, and a cap over the cover to expose little of the lamp. The electricity supply could also be a danger, but I will ensure the wires are out of the way of tripping over, pulling the plug and causing any problems. Jack Webdale 02/05/2007 Page 5 The Second is the possibility of a dropped lens, leaving shards of glass on the floor, and in extreme circumstances these shards going into someones eye. To avoid this as much as possible, the lens will be placed in its holder, away from the edge of the bench. Also, if the lens is dropped, it is to be swept up immediately and a new lens to be used. The Results The experiment worked out sufficiently, although one result, where the object distance was 20.6cm, the Avg. V Distance was around 60.4 cm. I knew this must be an error due to the pattern of the decreasing V distance, and the Focal Length of this result would have worked out to be 15.361 cm, which is quite far out from the other results. Due to this I repeated the experiment for this result, using the same apparatus, which I had numbered in case this occurred. The Graphs of these results are on a separate sheet of graph paper. To be precise, I performed each measurement twice to ensure I hit the mark each time. The second measurement was basically a check for the first. I could not take results more than two decimal places for accuracy, as I merely used my own vision and judgement. If however, I had Specialised measuring equipment, this could have been more accurate. Evaluation and Conclusion For plotting the graph, I also needed the separate data for 1/V and 1/U. So I put them in the following table to allow me to successfully draw the graph. After analysing the graph, it can be seen that a strait line can be drawn through the points. This means that the Object distance (U) is Inversely proportional to the Image distance (V). Thus we can say that when any result is taken for say U, put in its reciprocal form, and then added to the reciprocal of V, the result is always the reciprocal of the focal length of the converging lens being used (discarding errors and inaccuracy in this statement). On my graph, it can be seen that the line doesnt travel exactly through every point, but in all cases travels through the error box. This shows that if the results were perfectly calculated without any chance of error, all the points would lie on a strait line. It also shows that although I conducted my experiment as accurately as possible, small errors did occur. With the graph, I have determined that the equation of the line is 1/v = (-1)1/u+1/f. From this statement the gradient of the line is always -1, and this is always the case wha tever the reciprocal of the focal length. Also, due to the -1 gradient, the X-axis intercept is also the reciprocal of the focal length. With the graph, I can determine the experiment was successful, as the straight line travels through both axis and at almost the same points. On the Y-Axis 1.167cm and on the X-axis 0.066cm. They both give a focal length of approximately 14.9cm Knowing that the focal length is approximately 15cm, I can conclude that my experiment was successful, and thus proves that the lens formula 1/U + 1/V = 1/F is valid. I decided not to put error bars on my graph, as I was not using the whole values of v and u, where I knew the errors spread over a 0.5cm distance for each measurement taken. However, even though I took middle values of v, it is still evident that errors took place. If I were to repeat the experiment, I would choose to take two values of u, the object distance as well as v then take the middle value. This may also reduce the chance of inaccuracy due to the human eye. There are little ways in which I could improve this experiment, except take many readings of a result, then take an average value. Doing this for every measurement taken, however, would be very time consuming, and if one reading happened to be far out, the average would not be that accurate.

An Introduction by Timothy Borchers Has Already Given Her Essay

An Introduction by Timothy Borchers Has Already Given Her - Essay Example (Ritchie, J. and Kathleen Boardman 1999). Mary Daly also published many written works, and her second book, Beyond God the Father is of real interest, as this scholar really considers God as a substantive subject. Theoretical perspective In the book Beyond God the Father, Mary Daly lays out a systematic theology that is in line with the example set by theologian Paul Tillich. Daly’s work in the book Beyond God the Father is usually regarded as a foundational work in feminist theology. (Hoagland, S. L. and Marilyn Frye, 2000). She tries to explain and overcome andro-centrism regarding Western religion in this book, and utilizes a more playful writing style. She also attempts to rehabilitate discussions about God by emphasizing and critically building on the writings of existentialist theologians like Martin Buber and Paul Tillich in an effort to rehabilitate the liberation movement for women. Mary Daly’s response to the argument that Jesus was a feminist that this was fi ne and wonderful merits more attention, as any religion or gospel that fails to promote the full humanity of women is questionable, unworthy of public assent. This one legitimate point that must be made in the issue of how the gospel connects with feminist theology. It is notable that the claim that it can help in unmasking a form of oppression that seems, knowingly or unknowingly to have been built into the very fabric of every society that we know much about is the reason why feminism and feminist theology is so significant. Although the publication of some of Daly’s ideas were greeted with considerable furor and she was threatened with losing her job at Boston College, she was finally granted tenure after several months during which students protested vigorously and with widespread media publicity. This experience somewhat radicalized her views about the oppressiveness of prevalent patriarchal structures, led to her being transformed from a reformist Catholic into what can be considered post-Christian radical femininism. Daly also challenged the whole edifice of patriarchal religion. As she notes, the theological constructs and myths of patriarchal religion tend oppress one half of the human race and foster social structures that lead to racism, as well as , as ways of thinking that bring about war and genocide through the legitimization of male superiority and displacement of evil towards females as the proto-typical other. (Daly, M. 1973) Daly rejects the concept of God as a Supreme Being (static noun) rather than a Be-ing (active verb) and also argues against the general gender identification of God as a male. As she notes, â€Å"to objectify God as a being, to hypostatize transcendence, is to envisage transcendent reality as finite. God then functions to legitimate the existing status quo.† (Daly, M. 1973) Mary Daly put a lot of effort into breaking down some well known boundaries of critical theological thought. She was instrumental setti ng the stage for subsequent feminist theologians like Elisabeth Schussler Fiorenze and Rosemary Radford Ruether, who later began to come up with critiques of theology that helped in reshaping current Christian thought. Although many feminists are reluctant to speak of women or the experiences of women as a universal or

Identifying Cash Flow problems and planning for solutions Assignment

Identifying Cash Flow problems and planning for solutions - Assignment Example Of the total sales of $208,000 in January, $20,800 was cash sales, and another $20,280, net of commission was from credit card sales, making a total of $41,080 collectible in the month of sales, namely January. Of the remaining $166,400, $55,470 is collectible in each of the following three months, namely February, March and April. Thus the total collections for the month of April against the sales of $208,000 are only $41,470. The expenses during the month of January are $187,070, of which $103,740 is against variable costs and $83,330 are fixed costs. Consequently, there is a shortfall of $145,990 in the month of January. Similarly, there are shortfalls in the cash flows for the months of February and March to the tune of $106,490 and $46,530 respectively. The cash flow turns positive from April onwards showing that this is a temporary problem, as the cash collections from previous months will compensate for the delays in the subsequent months. However, such situations can recur in future if there is a sudden growth or dip in sales during a particular period. It is obvious, from the above analysis, that the problem arises because of the delay in cash collections. There are several approaches that can be used to tackle this problem. Some of the possible measures that can be taken include taking deposits, offering discounts for prompt payments, and factoring receivables (Katz & Green, 2009, p. 464). In the case of Bulltuff, the most appropriate among these seems to be to offer a discount for early payment. Taking deposits may not be a viable alternative as all customers (dealers) may not agree to it. It cannot be implemented selectively on only a few willing customers. Factoring receivables is likely to be costly. Consequently, offering discounts for early payments appears to be the most workable solution. The company could also simultaneously consider steps to delay the cash outflows

Causes Of Animal Extinction Biology Essay

Causes Of Animal Extinction Biology Essay Abstract: This essay discusses about the causes of animal extinction. Animals are sidestepped as we tend to focus more on something that happens to our brethren. However, we also forget that what happen to our species, the human beings, it affects the animals and plants more, as they dont have the ability to think and manipulate the environment as skilfully as we do. Habitat destruction, uncontrolled hunting and trading spreading of diseases, and drastically changing climates are among the prominent causes of animal extinction. We are exposed to what animals are endangered, we are exposed to how we can conserve them, but we have yet to be exposed to what causes the extinctions, which will roll the ball for further research on how to prevent them. This would be useful, as prevention is always better than cure. Animals are part of our ecosystem, not only they contribute to the ecosystem and help to balance the ecosystem, they also have many uses in our daily lives, as the source of nutrition, researches, pets and trading. But due to humans greediness, selfishness and also expand in populations, caused the population of the animals to decrease up to the point that they are in danger and eventually disappear from the surface of Earth like Dodo bird and Tasmanian Tiger. Yet, this issue is ignored or sidestepped as we care more of what affect us directly, when we should know that sooner or later, as part of the mammal species, these phenomena will also happen to us. Habitat fragmentation, destruction or loss, unsustainable hunting and wildlife trade, global warming and disease are the factors that lead to animal extinction. Based on AZEs  [1]  calculation, endangered species under their observation consist of amphibians (408), birds (217), mammals (131), and reptiles (15). This could be referred to Figure 1  [2]  . Figure Habitat Fragmentation One of the main factor of animal extinction is habitat fragmentation, loss or in another word habitat loss. Research had been carried out by Bancroft and Turchin in year 2003, using a series of experiment with grain beetles, Oryzaephilus surinamensis proved that 6% out of 247 populations went extinction  [3]  when they carried out the experiment on the relationship between habitat fragmentation and decreasing food abundance  [4]  and the result shown that these grain beetles went to extinction due to low food supplies. This result gives a suggestion that habitat quality is more important than the habitat size itself. Not only are that, another study that was carried out by Warren, another researcher, who does research on 13 types of protists in 1996  [5]  by applying three levels of habitat destruction of microcosm. As the result, the population of the surviving species greatly declined due to the rising in habitat destruction. As we know, Tropical Rainforest  [6]  co nsisted of many precious trees that used as the materials in industrial purpose. Not only for industrial uses, but also as the habitat for variety of species. Due to the huge demand by various parties, more trees had to be cut down to satisfy the demand of the parties. As the result, that inhabitants population begin to decrease as theres not enough place to live and hunt. If this is prolonged, the animals species will go extinct. Unsustainable Hunting and Wildlife Trade Another factor that contributes to animal extinction is unsustainable hunting and wildlife trade. This happened in many countries across the world. Many animals were hunted to extinction when the aboriginal Europeans, Americans and Australians developed the effective hunting technology  [7]  . One such animals were hunted to extinction by this is the Dodo birds. Certain bird such as the Eskimo curlew went extinct when they were relentlessly hunted by the market gunners during their migration. Some animals were caught for pet trade such as orang utan. These animals are considered exotic and were sold to the people that are interested in this kind of wildlife animal and were willing to pay for it. In one of the most outrageous cases of simultaneous drug and wildlife smuggling which occurred at Miami Airport in 1993, 312 boa constrictors that arrived from Colombia were found carrying inside them 39 kilos of cocaine. All of the snakes eventually died  [8]  Ãƒ ¢Ã¢â€š ¬Ã‚ ¦ Shows t hat wildlife not only kept as pet but also for drug trading purpose. Animal such as leopards, jaguar and Guadalupe fur seal were highly favoured for their beautiful furs was hunted to get their pelts and the same goes to tigers where poacher killed them for their body parts which are used in traditional medicine and aphrodisiacs  [9]  . Not only tiger was hunted for this purpose, but rhinoceros and elephants too, were hunted for their tusks. All these items were sold for high price in black market. Commercial whaling for their meat and oils  [10]  had threatened the most of the Baleen whale and several toothed whales species in the world. Whales meat is popular among the Japanese and its one of their favourite dishes, thus in order to meet the demands in Japan, every year whales was hunted during whaling season. Primates are often captured for research purpose especially in well developed country. They are trade to the biomedical lab with certain price and this biomedical la b will use them as research in finding cure for certain disease. An example of primates that often used in this field is chimpanzees. Even though they are not yet extinct, but they are classified as the endangered species because they are not only used in research but also become the target of the bushmeat hunter. Global Warming The third factor would be global warming. Mother Earth and its residence depend on the seasons for their routines and timings. Mating season, migration, all of it due to the weather. With global warming, the timing of seasons is changing. Some are longer than expected, some are shorter than hoped. This bungled the biological clock of animals that are already accustomed to instinct-based timing and activities. While it seems nothing to us humans, it is consequential towards animals and plants. Migration accelerates.( will expand later) Dehydration, combined with the rapidly vanquishing habitats, causes certain species to vanish.(will expand later) Stuart Pimm, an expert in extinctions and biodiversity at Duke University in Durham, North Carolina stated that species living in the ecological sites are more vulnerable, as they dont have much choices of places to migrate to when the temperate changes  [11]  . It is interesting to note that not as expected, the animals living at the polar (North Pole and South Pole) is not as vulnerable as the animals living in other climates, though the poles have experienced seen differences. That is because of the scarce geographical places the endangered species can run to is smaller than them. Dangerously, not only animals in endangered spots that are facing the fatalities. According to biologist Terry Root, of Stanford Universitys Center for Environmental Science and Policy, many species are striving to hold on to their current locations.  [12]   Disease There are two groups of diseases: natural occurrence, which is formed since a very long time and unpreventable, and the other one would be human-induced or mutated. Both would give dire consequences on the species affected, especially in masses. Among the example of human-induced diseases are effects of insecticides. Insecticides are regarded as a low-level dangerous substance, as they tend to prevent high crops loss. However, it also forced pests and infections to evolve. Once evolve, we would need a higher dose of insecticides. In the end, the effects of insecticides in plants will affect the animals that eat them too. Besides that, there are effects that happen not to the animal directly, but towards the next generation. A hen may lay eggs with thinner and fragile eggshells. This, while seem minor, could actually cause a higher risk of survival. In the long run, extinction would not be far in the future of the species. This really did happen. One insecticide, DDT, caused the eagle and peregrine to produce eggs with fragile eggshells, causing the eggs to break when the mother sit on them  [13]  . How can they be incubated without the mother warming the eggs? How can the mother incubate the eggs without sitting on them, yet when it sits, they will break? These are among the complexities that we dont comprehend or didnt put into the equation when we create the insecticide. Too much protection would also be unhealthy. When a species is protected from risks and diseases up to a paranoid level, it causes them to have lower and lower immunity to their offspring. This causes them to be weak and unable to sustain injuries and total fatalities if they ever catch any infections. Lastly under the factor of diseases, are the effects of genetic evolution. While it was not the total annihilation of species, it is still, in a sense, the cause of species extinction, happening due to the chances of survival with the enhanced or reduced ability. Perhaps a smaller or robust body is better adapting during this period of time, whereas speed and agility is more vital during the past. This theory applies to the birds, where during prehistoric times; birds have wider scales of bones while they have smaller lighter body now. Habitat, food consumption, and brain metabolism, all contribute towards genetic evolution, causes the extinction of the older type of species in exchange for a better, new species. Conclusion Thus, it is supported that the evidently seen causes are habitat loss, unsustainable hunting and trading of wildlife, global warming, and finally, infectious diseases. Two of it in which we contributed a lot in making it much worse, and two of the latter in which we have taken part albeit indirectly. Although a little out-dated, this research still hold a whole lot of truth. It is hard to fund more of these kind of research, as we humans are more interested in studying further of subjects that brings more material benefits instead of invisible threats. We are keener on studying on the psychology of potential customers, convenient products, and less consumption of resources. These researches are conducted with good intentions, but obsession of a narrow topic makes us putting a blind eye over other things that matter too, namely, other creatures co-existing with us. Some of the references here were spoken on 2006. Now, its 2011. In the span of 5 years, how much have we lose, can you imagine?

Three Strike Laws Essay -- Law Laws Argumentative Persuasive papers
