Insects vs Animals Essay Example

Insects vs Animals Essay Why do we not care about exterminating a whole society of insects, but we start riots and revolts over the killing of animals like elephants, dolphins, whales, rhinos, and other nearly extinct animals? We have reasons to kill these animals just like the insects, the slaughter of these animals temporarily benefits us, but what people do think about is what will happen if we eliminate every single insect of a certain species. Rachel Carson is an incredibly brave individual for writing Silent Spring.She had no doctorate in the field of environmental science, yet she still did her research and spoke her mind about the fact of the matter, and that matter being the killing of mass amounts of insects using pesticides. DDT was the main pesticide she was incredibly angry about because of the hidden or unknown effects it had on the environment. If there was one chapter that sticks out more than the others it would be the last one, The Other Road, which mainly focuses on the work Dr.Knipling wa s experimenting with. In this chapter Carson writes about the different way we could eliminate the insects without harming our environment with the dangerous DDT compound. Ways like sterilizing the males so they cannot get the females pregnant, extracting pheromone from the female and spreading it over a large area it try and mask the real pheromone emitted by the female and the male can then not find her. All are great ideas but how do we know they will be safer than DDT.We do not, just like we had no idea that DDT was going to have a extreme effect on the environment, there is no way to be able to account for every little reaction that the new drug we are spreading will not devastate our ecosystem. I think that it is a well known fact that people overall do not like insects for many sorts of reasons. They annoy us, they land on us, they bump into us, they drink our blood, the carry diseases, they land on our food, and off hand I can only think of one possible benefit to one partic ular insect: the bee, and only for spreading pollen from flower to flower.So overall we want to get rid of these insects as soon as possible because they do not contribute to anything productive in any population. It is very difficult to compare something that is seen as a pest and useless, meaning an insect, to something as that is seen as being beautiful and majestic, meaning wild animals. Why do people see insects as an annoying nuisance? In the early twentieth century we have just come out of the American agricultural revolution, and we were exponentially increasing the amount farmlands and with it crops.Insects then took advantage of what that had available to them, like the massive amount of food we are farming to feed our growing population. Farmers were getting very upset at the amount of crops wasted by insect infestation. The single most important reason as to why there will never be an uprising for killing to many insects is simply because no one cares for them. There is another reason though, one that scientists think about more than the general public. The sheer number of insects within a given area is bound to exceed our expectations.So many in fact it is nearly impossible to exterminate all of them. Due to the great amount of insects it is impossible to try and poison them because I can guaranty you that a couple of the billion will be immune to it. And if a couple of them are then they can repopulate and the new population will be immune to the previous poison we tried to use. We could kill the most amount of population by using two or more types of poisons which should eliminate this problem, but this problem will almost always occur due to the sheer size of the community of insects.Comparatively when people try to kill dolphins or whales we will react drastically different than someone plotting to exterminate a hoard of termites or insects that eat crops. It seems slightly strange to explain why, but because dolphins and whales are short in n umber and if we kill them off we will have killed yet another species of animal that will never be seen on planet earth ever again. We also have no clue as to what effect it can have to the ecosystem after they are gone.When we talk about attempting to clear an area of insects we should not mean to kill the whole population, but when we hunt nearly extinct animals we might possibly rid the whole population on accident. Like I said before, we have a reason for killing whales, dolphins, elephants, and rhinos, for their blubber, meat, and ivory. We get a personal gain from killing these animals, and to some it seems like it is unjust. We are killing innocent beings only for a small insignificant part of their bodies.Insects on the other hand are pests, people do not see any benefit in having them so why do we need them? To sum up the point that I am trying to make, insects so not have a substantial value to us, or at least we cannot see it. But animals, especially animals on the verge of being extinct, do have a value to us. Whether is be because we won’t see them again, or because we like to use the various parts of them for our benefit. So we do not care about the pests we call insects, and we do not care if we kill large numbers of them for our own benefit.

How to Write a Law School Case Brief

How to Write a Law School Case Brief Writing a  case brief  can be rather easy once you’ve got the format down. While this guide focuses more on the structure of a written brief, you should keep most of the elements when doing a book brief as well. Read through a case once before you begin briefing, and then focus on the important parts of the case, which will become the elements of the case brief: Difficulty:  Average Time Required:  Depends on length of case Here's How Facts:  Pinpoint the determinative facts of a case,  i.e., those that make a difference in the outcome. Your goal here is to be able to tell the story of the case without missing any pertinent information but also not including too many extraneous facts either; it takes some practice to pick out the determinative facts, so don’t get discouraged if you miss the mark the first few times. Above all, make sure you have clearly marked the parties’ names and positions in the case (Plaintiff/Defendant or Appellee/Appellant).Procedural History:  Record what has happened procedurally in the case up until this point. The dates of case filings, motions of summary judgment, court rulings, trials, and verdicts or judgments should be noted, but usually this isn’t an extremely important part of a  case brief  unless the court decision is heavily based in procedural rules- or unless you note that your professor loves to focus on procedural history.Issue Presented:  F ormulate the main issue or issues in the case in the form of questions, preferably with a yes or no answer, which will help you more clearly state the holding in the next section of the case brief. Holding:  The holding should directly respond to the question in the Issue Presented, begin with â€Å"yes† or â€Å"no,† and elaborate with â€Å"because†¦Ã¢â‚¬  from there. If the opinion says â€Å"We hold†¦Ã¢â‚¬  that’s the holding; some holdings aren’t so easy to pinpoint, though, so look for the lines in the opinion that answer your Issue Presented question.Rule of Law: In some cases, this will be clearer than others, but basically you want to identify the principle of law on which the judge or justice is basing the resolution of the case. This is what you’ll often hear called â€Å"black letter law.†Legal Reasoning: This is the most important part of your brief as it describes why the court ruled the way it did; some law professors dwell on facts more than others, some more on procedural history, but all spend the most time on the court’s reasoning as it combines all parts of the case rolled in one, describing th e application of the rule of law to the facts of the case, often citing other court’s opinions and reasoning or public policy considerations in order to answer the issue presented. This part of your brief traces the court’s reasoning step by step, so be sure that you record it without gaps in logic as well. Concurring/Dissenting Opinion:  You don’t need to spend too much time on this part other than the pinpoint the concurring or dissenting judge’s main point of contention with the majority opinion and rationale. Concurring and dissenting opinions hold lots of law professor  Socratic Method  fodder, and you can be ready by including this part in your case brief.Importance to class: While having all of the above will give you a complete brief, you may also want to make some notes on why the case is important relevant to your class. Jot down why the case was included in your reading assignment (why it was important to read) and any questions you have about the case as well. While briefing cases is always helpful, your brief is most important in the context of the class that it is for. What You Need Case bookPaper and pen or computerAttention to detail

Robert Guillaume Essay Example | Topics and Well Written Essays - 750 words

Robert Guillaume - Essay Example It was this very relentless fight against reality along with virtue of talent, persistence and unwillingness to bow down to anyone which bolstered his way out of the St. Louis slums to glory. Robert Guillaume was born on November 30th 1927 in St. Louis Missouri (IMDB, 2008). He was mostly in the care of his grandmother and had a strict catholic upbringing. This was where Robert first discovered his true identity. Robert discovered a talent in himself and distinguished himself by singing church music (Guillaume and Ritz, 2002). In his autobiography, Robert states, "In my mind music carried me from the St. Louis ghetto to the magnificent cathedrals of Germany, Italy and France" (Guillaume and Ritz, 2002). In 1945, Robert joined the US Army, something that was never destined to work out coherently. His rebellious and outspoken behavior caused friction with his captain and within 15 months, Robert resigned with honorable discharge (answers.com, nd). To cherish his grandmother's wishes Robert enrolled in evening classes at Saint Louis University majoring in Business Administration, but destiny had decided that performing arts was where Robert was the perfect fit. Soon after, Robert joined the prestigious music school of Washington University. Finally at the age of 31, Robert had his professional debut in the Karamu's production of Carousel (answers.com, nd). ... Ever since, Robert performed at several productions by various theatre groups. He kept jumping careers, joining new groups, visiting places and continuously improving his performances. In 1970 when he first appeared in Some place to be Somebody, he called it his first real acting debut. Robert Guillaume was one such actor who continually defied stereotypes. His commanding theatrical presence brought the actor a 1977 Tony nomination for his portrayal of Nathan Detroit in "Guys and Dolls," with an all black cast (speakingofstories.org). He had finally arrived. On his next project, Benson that had an interracial casting, Robert insisted on his character being equal to that of any other character; eventually his character turned out to be the most brilliant. Soon he left for television. This was mainly because he was informed that the movies market was not doing very well. He got a character of a butler for the nighttime satire called Soap. In 1979 he received an Emmy award for this role . Soon his roles caught the attention of top league and he was given a chance to add a 3-dimension persona to his role in Benson to reflect the progress of the Afro-American community on America. Such a position had never been attained by minorities in America in the theatre field. After his stint with television, Guillaume hit the nightclub circuits, singing in places like Las Vegas and Atlantic City. He also formed his own production company, Longridge Enterprises. This company was to develop acting projects. Perhaps his greatest theatrical achievement came in 1990, when he was chosen to play the character of Phantom in Andrew Lloyd Webber's spectacular musical The Phantom of the Opera. His selection was met with controversy by several audiences. Some

American History - Term Paper Example Unequal conditions among the blacks and the whites were rampant in almost every sector and part within the country. Considering that the blacks received unfair treatment than their white counterparts, the demonstrations were justified. Considering the cause of reasons behind these protests, i would advice that it is right to support the demonstration as opposed to the white students during that period who failed to support their fellow black students’ demonstrators. The next incidence that occurred in the following year relates to the Weather Underground Organization formation. The organization founded at Ann Arbor branch of Michigan University aimed at achieving a democratic society by students. The primary objective as evidenced through the naming of the faction as Students for a Democratic Society was to work as a radical left wing that would materialize and succeed in overthrowing the American government. October 8, 1969 characterized the first demonstration organized by t he group in Chicago that was deliberate to coincide with the trials of Chicago eight. The group embarked on bombing demonstrations, jail breaks among other ill forms of demonstrations. The attacks mostly focused on government buildings as well as various banks while evacuation warnings were also given to others. It is important to note that these students’ demonstrators grew to become criminals over time and facilitated bombings or became parts of bombings after their engagement in 1969. Although the authorities failed to engage them forcefully to abandon their demonstrations, deaths among the students were reported on various occasions. My opinion relating to such engagements falls against joining such students owing the acts of violence the group engaged in, it is ill-advising for any student of the current multi-cultural and civilized U.S to participate in such demonstrations. From

Secondly the threat of impact on one would lead to impact on all which has been seen in the case of European Union. Therefore each of these three nations would object to this idea. Other challenges include the rate difference in the currencies of the three states. The possible solution can be found in form of domestic currency versus international currency as a common currency. However it is still far from practical implementation. In personal capacity, having seen the challenges faced by the European states and especially with the relatively meager states in Europe such as Greece, Portugal and Spain that have been time and again bailed out and despite that they have found it difficult to continue with the common currency, therefore a common concept prevails that the common currency may not go too well in the favor of the weaker economic states such as Mexico in

Concepts of Deterrence and Diplomacy

Concepts of Deterrence and Diplomacy Previously, the paper has examined what diplomacy is and its types. Through the previous discussion, human and politic capability seen as the main player in carries-out diplomacy. Through this chapter, the paper will discuss on deterrence as diplomacy means. With quoted the words from Carl Von Clausewitz, a military strategist and theorist: War is the simple continuation of diplomacy by other means. On the words, Carl Von Clausewitz emphasized that war is not only as an actor in politic, thus as the instrument in politic. War could influence politic decision making.[1] Nowadays, WMD might be used as another diplomatic means to achieve one countrys goals. Deterrence is significant theory in Strategic Studies and in International Relations as well. Since the age of Cold War, chiefly on Cuban Missile Crisis event, deterrence has been viewed and used as the greatest mediator to attempt influence the decision making of the states. Deterrence can be ciphered as social and politic relations primarily enable one party in influencing the other party action. Deterrence is implemented and executed to ensure its opponents abide by its will.[2] On the other words, deterrence is a belief on strategic capability to avoid or prevent itself from being attacked by its opponents the opponents believe that it is not worth to take a military action on the state (Charles W. Kegley Jr. and Eugene R. Wittkopf, 1998). TYPES OF DETERRENCE On this chapter, the paper will examine the types of deterrence as well on the previous chapter which is study on the types of diplomacy. There are three types of deterrence that has been identified by military analysts namely deterrence by denial, deterrence by punishment and deterrence by defeat. Deterrence by denial can be described as the country would not to initiate war when the country assured it could not win the battle.[3] On the other words, State A will attempt to convince State B will not achieve its military-political goals if State B undertakes a military action. As a consequence, the war could be evaded.[4] Meanwhile the country that might to initiate or engage a war would not to do so because the country convinced that it would impose unacceptable damage (as the aftermath or punishment if involve in war) if the country attack the other country this statement portrays what is deterrence by punishment. State A will endeavor to indicate State B that it (State A) will retaliate by obliterating assets that State B highly values if State B commits a particular action such as an invasion. In this context, State A should have great political power (as threat) to deter State B from committing the act. In the other hands, the deterrence will fail if State B acts despite the threat.[5] Deterrence by punishment may be posed an action on other states industry, population, or even the lives of its leader. (Keith B. Payne and C. Dale Walton, 2002). Through-out the words, we can conclude that the purpose of deterrence by punishment is to shape opponents decision making by signal them the aftermath or cost that the opponents will to bear of. While deterrence by defeat shows the state will not to engage or initiate a war because the state certainty that it will be defeated.[6] Via this discussion, in a nutshell, deterrence is the other means to prevent war. Deterrence can be viewed as the other means of diplomacy. Deterrence can be defined as the barrier to prevent war from being occurred. During First World War and the Second World War, war has brought greatest devastating towards mankind, nature, development and war leave bad effect on future generation mainly aftermath of using nuclear weapon. Is it as a signal that the deterrence is another means of diplomacy? It will discuss further on the next discussion. HOW DETERRENCE CAN BE ANOTHER MEANS OF DIPLOMACY? The question left here how deterrence can be a player or an actor in international relations and diplomacy. It is fascinating subject to examine the role of deterrence as diplomacy means. In answering the questions, we need to refer on the papers previous discussion which is what deterrence is and how its carry-out. The adaption of deterrence in international relations is to ensure State B will not take an action that could threat State A. If the State B wishes to do so, State B will bear devastating consequences. This circumstances show that State A attempts to warning and avert any pre-emptive action towards State A. By way of this statement, it represent that deterrence can be adapted as diplomacy instrument which is known as diplomatic bargaining in relationship of the state and the state action in international relations.[7] Psychology tactic and strategy are the finest way to describe the threat that created from deterrence. Deterrence crafted a threat without any physical demolition when deterrence proposed by the state is succeeded. The ambiguity of deterrence as another means of diplomacy still exists. Negotiation and discussion are among the significant elements in diplomacy. But how negotiation is present in deterrence? It is questionable question on this argument. The threat through deterrence is the negotiation. The deterrence represents and delegate the state to let the other state consider or think wisely is it worth to attack the state. In this situation, the other state have a chance to take further action on the state or else.[8] Generally, state will not take an action that it detrimental its people, politic position and economy. The succeed deterrence capable to protect its national interest for the reason that its politic goals achieved. Deterrence is the means to convince the other party (opponents) not to initiate a war toward the state. (Charles W. Kegley and Eugene R. Wittkopf, 1989). The capacity and the capability of nuclear weapon such as the development of ICBM which is leaving the impact of total destruction has been assessed or as a value toward head of the state in making decision concerning on action towards another state. As it concerned, deterrence is effective in preventing a nuclear war from occur in international system until today. The capability of nuclear can activate or enhance the deterrence (Marc A. Genest, 1996). After the discussion, the paper will confer on the using of deterrence in Cuban Missile Crisis.

Air Pollution   Ã‚  Ã‚  Ã‚  Ã‚  Ã¢â‚¬Å"Air pollution is a serious problem in many of the worlds large cities. Heavy concentrations of air pollutants, which are often in the form of smog, settle over a city, creating a health hazard for its people. Air pollution occurs when wastes dirty the air. People produce most of the wastes that cause air pollution. Such wastes are usually in the form of gases. These substances result chiefly from burning fuel to power motor vehicles and to heat buildings. Industrial processes and the burning of garbage also contribute to air pollution. Natural pollutants include dust, pollen, soil particles, (100 Words) and naturally occurring gases.†Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  (Encyclopedia)   Ã‚  Ã‚  Ã‚  Ã‚  Ã¢â‚¬Å"The rapid growth of population and industry, and the increased use of automobiles and airplanes, have made air pollution a serious problem. The air we breathe has become so filled with pollutants that it can cause health problems. Polluted air also harms plants, animals, building materials, and fabrics. In addition, it causes damage by altering the earth’s atmosphere.† In and article published by THE NEWS in New Mexico they warned â€Å"If current environmental protection policies are no unforced, pollutants in city air will increase one million tons annually by year 2010.†Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   (Encyclopedia, The News)   Ã‚  Ã‚  Ã‚  Ã‚  Ã¢â‚¬Å"Air pollution (100 Words) can have a huge effect on health.

When states fail to enforce the regulations, the federal government can act against the polluters by imposing fines.

Old Mrs Grey

â€Å"Old Mrs. Grey† Born in 1882, Virginia Woolf was an author, feminist, critic, essayist, pacifist and one of the founders of the Modernist Movement in Literature. Like many of her contemporaries in the Movement, she employed a vivid and descriptive stream-of-consciousness writing style that was rooted in the popular Freudian psychoanalytic theories of the day; and in fact, both of her brothers became psychoanalysts. Woolf regarded herself as â€Å"mad†, having bouts of debilitating depression brought on by her bi-polar disorder. Within her body of work, especially in her essay â€Å"Old Mrs.Grey†, you can see the melancholic/suicidal ideation of her own psyche deployed in the character of Mrs. Grey. She did not hold with the traditional views that suicide was sinful or cowardice. In 1941, she put rocks in her coat pockets and committed suicide by drowning herself in a river near her home in Sussex. The letter she left reasoned that she was â€Å"going mad ag ain and shan’t recover this time†. This is the background on how and possibly why Mrs. Woolf uses the imagery of hopelessness so effectively in this story as a surrogate for her own misery.In the story â€Å"Old Mrs. Grey†, Woolf’s depressively artful use of words describes a lonely 92 year old woman whose body has painfully palsy, â€Å"jerked her body to and fro†, and is in constant arthritic pain which, â€Å"twists her legs† and keeps her confined to her home where she sits in a â€Å"hard chair† and looks with â€Å"aged eyes† that have â€Å"ceased†. She sits by a dying fire in a hard chair, looking at â€Å"The morning spread seven foot by four, green and sunny. â€Å" a reference to the only life she knows now, looking through the door of her cottage at the life outside of it.This is emblematic of her longing for a bygone youth, which Woolf further describes, â€Å"†¦ (she) saw herself at ten, at twenty, a t twenty-five. †, a youth which has fled and left her nothing but memories. The poignant aspect of the story is that while Mrs. Grey is confounded by her longevity, though she longs for the Lord to â€Å"take her†, she never actually voices a propensity to end it herself. The author clearly feels that the advances of medical science that prolong her life, which are but a, â€Å"nail†¦that pinions†¦the body against a wall†, are an insult and occur seemingly against her will.However, as the protagonist notes, the doctor is a good man. The author implies that the doctor is in wonder that Mrs. Grey hasn’t died, but clearly shows that he takes care of her, as required by his oath, regardless of his personal opinion. Clearly, Woolf’s use of imagery and diction brings the reader into Mrs. Grey’s end of life suffering and morose loneliness. The reader, by the end of the story, can empathize with Mrs. Grey’s feeling of the pointlessne ss and uselessness of her remaining days and her longing to â€Å"pass on†, because of Woolf’s competent characterization of Mrs. Grey’s somber situation.

How to Calculate Mass Percent Composition

How to Calculate Mass Percent Composition This is a worked example problem showing how to calculate mass percent composition. Percent composition indicates the relative amounts of each element in a compound. For each element, the mass percent formula is: % mass (mass of element in 1 mole of the compound) / (molar mass of the compound) x 100% or mass percent (mass of solute / mass of solution) x 100% The units of mass are typically grams. Mass percent is also known as percent by weight or w/w%. The molar mass is the sum of the masses of all the atoms in one mole of the compound. The sum all the mass percentages should add up to 100%. Watch for rounding errors in the last significant figure to make sure all the percentages add up. Key Takeaways Mass percent composition describes the relative quantities of elements in a chemical compound.Mass percent composition is also known percent by weight. It is abbreviated as w/w%.For a solution, mass percent equals the mass of an element in one mole of the compound divided by the molar mass of the compound, multiplied by 100%. Mass Percent Composition Problem Bicarbonate of soda (sodium hydrogen carbonate) is used in many commercial preparations. Its formula is NaHCO3. Find the mass percentages (mass %) of Na, H, C, and O in sodium hydrogen carbonate. Solution First, look up the atomic masses for the elements from the Periodic Table. The atomic masses are found to be: Na is 22.99H is 1.01C is 12.01O is 16.00 Next, determine how many grams of each element are present in one mole of NaHCO3: 22.99 g (1 mol) of Na1.01 g (1 mol) of H12.01 g (1 mol) of C48.00 g (3 mole x 16.00 gram per mole) of O The mass of one mole of NaHCO3 is: 22.99 g 1.01 g 12.01 g 48.00 g 84.01 g And the mass percentages of the elements are mass % Na 22.99 g / 84.01 g x 100 27.36 %mass % H 1.01 g / 84.01 g x 100 1.20 %mass % C 12.01 g / 84.01 g x 100 14.30 %mass % O 48.00 g / 84.01 g x 100 57.14 % Answer mass % Na 27.36 %mass % H 1.20 %mass % C 14.30 %mass % O 57.14 % When doing mass percent calculations, its always a good idea to check to make sure your mass percents add up to 100% (helps catch math errors): 27.36 14.30 1.20 57.14 100.00 Percent Composition of Water Another simple example is finding the mass percent composition of the elements in water, H2O. First, find the molar mass of water by adding up the atomic masses of the elements. Use values from the periodic table: H is 1.01 grams per moleO is 16.00 grams per mole Get the molar mass by adding up all the masses of elements in the compound. The subscript after the hydrogen (H) indicates there are two atoms of hydrogen. There is no subscript after oxygen (O), which means only one atom  is present. molar mass (2 x 1.01) 16.00molar mass 18.02 Now, divide the mass of each element by the total mass to get the mass percentages: mass % H (2 x 1.01) / 18.02 x 100%mass % H 11.19% mass % O 16.00 / 18.02mass % O 88.81% The mass percentages of hydrogen and oxygen add up to 100%. Mass Percent of Carbon Dioxide What are the mass percentages of carbon and oxygen in carbon dioxide, CO2? Mass Percent Solution Step 1: Find the mass of the individual atoms. Look up the atomic masses for carbon and oxygen from the Periodic Table. Its a good idea at this point to settle on the number of significant figures youll be using.  The atomic masses are found to be: C is 12.01 g/molO is 16.00 g/mol Step 2: Find the number of grams of each component make up one mole of  CO2. One mole of CO2 contains 1 mole of carbon atoms and 2 moles of oxygen atoms. 12.01 g (1 mol) of C32.00 g (2 mol x 16.00 gram per mole) of O The mass of one mole of CO2 is: 12.01 g 32.00 g 44.01 g Step 3: Find the mass percent of each atom. mass % (mass of component/mass of total) x 100 And the mass percentages of the elements are For carbon: mass % C (mass of 1 mol of carbon/mass of 1 mol of CO2)  x 100mass % C (12.01 g / 44.01 g) x 100mass % C   27.29 % For oxygen: mass % O (mass of 1 mol of oxygen/mass of 1 mol of CO2)  x 100mass % O (32.00 g / 44.01 g) x 100mass % O 72.71 % Answer mass % C 27.29 %mass % O 72.71 % Again, make sure your mass percents add up to 100%. This will help catch any math errors. 27.29 72.71 100.00 The answers add up to 100% which is what was expected. Tips for Success Calculating Mass Percent You wont always be given the total mass of a mixture or solution. Often, youll need to add up the masses. This might not be obvious! You may be given mole fractions or moles and then need to convert to a mass unit.Watch your significant figures!Always make sure the sum of the mass percentages of all components adds up to 100%. If it doesnt, you need to go back and find your mistake.

The Benefits of Mandating Physical Education in Schools Essays

The Benefits of Mandating Physical Education in Schools Essays The Benefits of Mandating Physical Education in Schools Essay The Benefits of Mandating Physical Education in Schools Essay Physical Education classes have always been a part of school systems all over the world. However, budget cuts, rising academic requirements, and ultimately, laziness, have put this essential course in Jeopardy. This has resulted In many parents, teachers, education officials, and most Importantly, students, speaking up and working to make physical education mandatory in schools across the nation because they believe that it has an abundance of positive outcomes. Physical Education promotes academic learning, teaches individuals to lead a healthy lifestyle, and is also proven to build self esteem, as well as character, in individuals. The aforementioned reasons should be more than enough to convince any skeptic of the importance of physical education. One of the most important benefits resulting from mandating physical education in schools is that it has the power to promote academic learning. Many studies have shown a direct connection between physical activities and good quality grades. For example, a study conducted by the Canadian Department of Health and Human Services states that In 201 1, 25 percent of teens who had taken part In physical education classes had achieved generally higher grades than those teens that did not take those classes. Additionally, it is proven that Physical activity increases blood flow and supports the brain to function more efficiently when dealing with academic work. Keeping this fact in mind, it would be much easier for children of all ages to succeed in classes such as Math, English or Science if they also had to take a Physical Education class. Also, in some cases, this physic al activity provides an energy release that helps kids from getting distracted and agitated when in the classroom.

Regular physical activity, especially for growing bodies (children), is one of the most important measures, if not the most important measure, you can take for your health. According to the Centers for Disease Control and Prevention, Heart Disease and stroke are two of the leading causes of death in the united States.

Physical activity gives students of all ages sense of mastery; they will think l accomplished something! This will also encourage students to set and work towards goals, building character, initiative and determinacy. For example, a gym student may work towards setting a better time for the mile run. Each time this student runs the race and sheds an extra couple of seconds off their time, they will visually and physically see their improvement and feel great about how their hard work paid off and improved their performance. It is difficult for students to find and actually feel the same sense of accomplishment anywhere else in their lives. It would be abundantly beneficial if schools decided to make Physical Education necessary in schools. A progress in academic learning, preventing diseases and helping people live longer and healthier lives, and building self esteem and character in individuals are the aforementioned benefits of mandating physical education in schools. Now that some strong reasons as to why physical education should be made compulsory have been made, does laziness still seem like a superior reason to why Physical Education should not be made mandatory?

According to the laundry business owner, Mr. Soares, this move will affect him and the six employees he has at the laundry because they will lose their source of income (Costas 2015).

The existence of god - Essay Example In this way, the analysis will seek to provide a thoughtful overview of some of the most salient critiques of Anselm’s ontological view as well as to provide the reader with the alternate views that philosophers have developed over the years in response to it. Stone asserts that Anselm’s argument purports that God is conceived as the being that supersedes other beings. He purports that God exists in both understanding and reality. This is because if His existence was perceived not to be in reality, another being greater than God could be conceived. Therefore, his argument articulates that God really exists. Gaunilo’s argument uses the model of a perfect island to counter-argue Anselm’s strategy (Stone). The perfect island is described as a piland taking the form of an island in the mind which in reality is perceived greater than the piland idea. He purports that the occurrence of a piland idea in the mind proves that the piland exists. Gaunilo did not iden tify the fault in Anselm’s theory, but warned that there is something wrong with it because if the theory was perfect, then its logic can be applied in proving things that one has no reason to believe to be true (Burgess 2). For instance, Guanilo suggested the possibility of constructing an argument like that of the ontological argument proving the occurrence of a lost island (Burgess 3). His critique replaces the term ‘God† with â€Å"lost island† and views the idea that anything than which nothing bigger can be conceived must exist. It is reasonable to point out that Anselm’s approach is a supposition that a tangible thing corresponding to an idea emanates from an idea itself. The objection to the ontological idea is that of defining things into existence which is viewed as impossible. Stone asserts that Gaunilo shared this worry to explain that a person could use non-existent things to portray the existence of non-existent things. According to Gau nilo, if the argument for a superior being works, even that of a lost island is true; which is absurd (Burgess 3). In his response to Guanilo, Anselm purports that the concept is only applicable to God, as He is the only being that can be conceived. According to Stone, Anselm argues that Guanilo’s lost island strategy is variably spurious because Guanilo provides no justification to prove the island exists. Additionally, a perfect island is perceived as the one with abundant lush palm trees and pristine beaches. This proves the incoherence of this argument because perfection cannot be quantified through reference to these features as each island is perfect in its own way. This implies that there is no greater island than which no greater island can be conceived. Consequently, the concept of a greater God is coherent. This is because the features that are used to describe God are superior to that any other being can possess e.g. moral goodness, power and knowledge. Similarly, Immanuel Kant, the 17th century philosopher who actually coined the term â€Å"ontology† and â€Å"ontological†, had a specific criticism of Anselm’s rather simplistic means of argument. Although agreeing with the premise that God existed, Kant sought ot further differentiate the manner by which human rational and understanding could necessarily seek to prove or disprove such an existence. As a function of this, Kant argued that
