In the United States 4% of men and 7% of women are defined as vegetarians Worldwide, vegetarians total 375 million (Figus et al.). There are many different types of vegetarians from those who do not eating anything that comes from an animal to those who just do not eat red meat. A highly common question asked is why choose the vegetarian diet? Everyone should be on the vegetarian diet because it is cruel to kill animals for food, humankind live longer on the diet, it is easier and more efficient to raise food for humans than animals, it is more environmentally friendly to not raise animals for meat, and it decreases chronical illness.. Don’t waste time! Our writers will create an original "Convert to Vegetarianism" essay for you Create order Some people go on the vegetarian diet because they feel it is wrong to kill animals for food. They believe that animals should be treated with more respect and that it is inhumane. That killing animals is not compassionate and is cruel. Scientists saw that animals were not only able to feel pain, but also capable of practical reasoning: they could learn and remember, and perceive connections between different phenomena (Sorabji). Animals can feel, learn and also remember just like humans can. Killing animals for food is not even necessary. There are many other thing to eat and get a full nutritionition diet. Vegetarians eat vegetables, grains, fruits, and legumes. Some vegetarians dont eat any animal products such as milk and cheese they are called vegans. Some humans would say that eating meat is not cruel, it is a natural part of the cycle of life. That everyone on earth dies or is killed at one point in life so others can live, It is not natural for humankind to kill. Children have been taught since they are little that it is not wrong to kill animals to eat; that is not natural. Humans are the only mammals that drink another animals milk. Nothing that humans drink and eat is a natural part of life. Humankind live longer while on the diet. It has been scientifically proven that vegetarians live longer because they are more conscientious about their body getting a balance nutritious diet. Vegetarian need to be careful and have a well planned diet to get all the nutritions and vitamins that are need for the body to function. With vegetarians so focused on what they are putting in their bodies, they are getting a extremely healthy diet, which is helping them to live longer. Vegetarians live longer with having a well-planned, balanced diet with sufficient fruit and vegetables (Ding). Some people say that the vegetarian diet does not affect how long someone lives. That the whole thing is just a myth, but scientist have proven that with the way vegetarians are eating, they are more aware of what the put in their bodies and choose to only put healthy foods in. Although animal protein has high amounts of iron, protein and other minerals it also has high amounts of cholesterol and saturated fats that cause heart disease, high blood pressure and high cholesterol. Also eating too much meat causes cancer such as colon cancer and stomach cancer. The vegetarian diet decreases chronical illness. Risk of death from cancer, heart disease, stroke, diabetes, infections, kidney disease, liver disease or lung disease all increased with the amount of meat consumed, and those people with the highest meat intake doubled their chances of dying from chronic liver disease. On the vegetarian diet humankind get the right amount of nutrients for the body. Those who eat a vegetarian diet have a lower risk for chronic diseases, which ultimately translates into longer, healthier living(Reeves). One issue people have with the vegetarian diet is that their is not enough source of protein. That the diet does not give enough protein to function. However there are many ways to get protein, such as cheese, beans, tofu, mushrooms, and jackfruit. While being a vegetarian you need to carefully plan what you eat to get a fully balanced diet with all the nutrients and vitamins needed. Forty percent of grain in the world is used for feeding animals. Just in the united states 800 million people could be fed by the grain fed to animals each year. Beef take 100,000 milliliters per kilogram. In contrast potatoes take 500 milligrams of water per kilogram( ). Humans can see the huge inefficient loss of water due due to the use of crops for feeding animals. Overgrazing is a huge problem which causes loss of soil due to erosion by both water and wind erosion. When hiking humans can see the degradation of the land due to overgrazing. They can also see the degradation of the streams and creeks due to cows destroying the riparian environment by eating the willows and plants near the water. The use of fossil fuels are the highest per kilogram per liter in beef production. Our fossil fuels would be better used in the production of plastics and other things that only can be created by crude oil. Also the raising and consuming of meat is a huge contribution to greenhouse gases. The amazon forest is being cut down to raise crops to feed to beef and other animals. Cows produce large amounts of methane which is many times more potent in causing global warming. Cow manure also produces large amounts of ammonia which is a big factor in acid rain. The vegetarian diet is the supreme diet for humankind. It is inhumane it kill animals just to eat them, for they can feel just as humans do. On the vegetarian diet you learn to balance your nutritions and vitamins to live a healthy long life. With the vegetarian diet you have higher chance of living longer and have a decrease in chronical illnesses. In all, the vegetarian diet is the perfect way to live long and happy life.

Discrimination And Prejudice Against The Elderly - 877 Words

T he term ageism refers to discrimination and prejudice against the elderly. The term was introduced into the American vocabulary in 1971 by Robert Neil Butler, MD (January 21, 1927 – July 4, 2010). He was the first director of the National Institute on Aging. According to Doctor Butler, the three primary prejudicial attitudes seem to be: (1) old age, and the aging process; (2) discriminatory practices against older people; and (3) institutional practices and policies that perpetuate stereotypes about older people. Much of what passes for knowledge and understanding of aging are myths, misleading information, or just bad information. Our youth oriented culture has developed a fear and prejudice against aging persons and unquestionably against lesbian, gay, bisexual and transgender (LGBT), intellectually and physically disabled seniors, and people of a certain faith and spiritual beliefs. The ability to distinguish, fear and prejudice based upon myths and misconceptions from truths and facts about older adults are vital to eldercare success. Ageism is not limited to America. It has become an international issue. There was a time when elders received respect for their knowledge and extensive memory of history. Two major historical events changed that perspective. The printing press allowed for sharing of knowledge and the industrial revolution sped us to a mobile society. Ageism seems to be rooted in the fear of the problems associated with growing older.

Human Nature By Mark Twain Free Essays

Conformity is defined by Zimbardo (1992) as, ‘A tendency for people to adopt behavior, values and attitudes of other members of a reference group.’ Mann (1969) identified the two major types of conformity: normative conformity and informational conformity. Normative conformity is caused by a desire to be liked. We will write a custom essay sample on Human Nature By Mark Twain or any similar topic only for you Order Now People conform because they think that other members of their reference group will like and accept them. They also want to avoid embarrassment and humiliation from other group members. It is a desire to be right that forms the basis of informational conformity; people conform because they look to others whom they believe to be correct to give them information. Humanity is questioned by acknowledging that self-approval comes from making your thoughts conform to the majority’s belief system. Mark Twain has always been a keen observer of human nature. For example, according to his article â€Å"Corn-Pone Opinions† he wrote about those people who he was surrounded with in his everyday life. Mark Twain’s idea that group thinking is inevitable is mirrored. Mark Twain, considered the â€Å"father of American literature†, attempts to define â€Å"Corn-Pone† and prove that it is based on the need for approval by other men of similar mindsets. In the opening, Twain writes about the positive qualities of his friend whom he is listening to without the permission of his mother. Another clear example of how he knows his mother has a reason for not allowing him to listen, based on her conforming to society’s belief against black men being equal to white. However, before he finishes he leaves the reader with the knowledge that the friend is in fact a slave. Thus Twain’s, Corn-pone Opinions, immediately shows that he too has fallen under the spell of public opinion. Otherwise why would Twain even mention that the friend is a slave. He is saying it is only human nature to believe what others believe and in this case it is the inferiority of the black man. I agree with Twain, he invites the reader to become aware that our opinions are strictly influenced by the actions of others and the acceptance of our peers. Slavery is a perfect example of an accepted belief, â€Å"changes are not reasoned out; we merely notice and conform†¦ As a rule we do not think, we only imitate†. This implies that slavery, itself, was a shared belief that quietly became the norm and thus accepted. Here, Twain was clearly stating he was a supporter of the abolition of slavery.In the short essay, The Corn-Pone Opinions, published after Mark Twain’s death in 1910, the great humorist, presents the notion that society’s beliefs are affected by social pressures to conform to an agreed upon norm. Basically, people have a natural tendency to conform and be similar to those around them. When a new idea or fad comes along it is first seen as odd and unflattering. As more and more attempt to imitate the new fad or idea it becomes accepted. The new idea or fad is only acceptable because all the others are doing it, â€Å"Even the woman who refuses from first to last to wear the hoop skirt comes under the law and is its slave; she could not wear the skirt and have her own approval; and that she must have, she cannot help herself. † Thus public opinion is based on nothing more that man’s acceptance of other’s thoughts. However, Twain is not preaching and presents the case through clear examples filled with extensive details and descriptions such as, â€Å"He was a gay and impudent and satirical and delightful young black man†. Similarly, Henry David Thoreau’s, Life Without Principles, concludes that man has accepted and conformed to society’s opinion and norm of working for wages. His essay includes several examples of how the everyday man is being turned into a slave by the need to work for wages and not live life based on love of life. His arguments are told through a series of stories. Each story illustrates the notion that wisdom and loving life itself are far more valuable than the â€Å"wages† they work so hard for every day. â€Å"To have done anything by which you earned money merely is to have been truly idle or worse. If the laborer gets no more than the wages which his employer pays him, he is cheated, he cheats himself†, beautifully displays Thoreau’s belief that being able to enjoy poetry or merely go for a walk in the woods alone, holds much greater satisfaction for the everyday man. Man must be able to see beyond the need to make a living by merely working for a paycheck. The evolution of, Life Without Principles, came out of lectures given in 1854. It was through those lectures that you see Thoreau’s philosophy aligning with Transcendentalism. Thoreau is begging man to follow his heart’s desire, in order to have a fulfilling and worthwhile life. Henry David Thoreau is stating that the corporeal things around us are beneath the spiritual ideals that perpetuate the universe. Mankind should be more concerned with living life, rather than making a living in order to survive life. Thoreau writes about doing a fulfilling job, one that you can be personally invested in and not just collect a paycheck from its’ completion. The fact that the essay was written in 1863 and published posthumously, is hard to believe as it clearly replicates the present day workaholic syndrome so prevalent in our society. It’s very similar in fact to the â€Å"rat race of business†. Life is a series of business deals and one is always in search of the almighty dollar as a reward for a good job. For example Thoreau writes, â€Å"This world is a place of business. What an infinite bustle! I am awaked almost every night by the panting of the locomotive. It interrupts my dreams. There is no Sabbath. It would be glorious to see mankind at leisure for once. It is nothing but work, work, work†. Thoreau also attempts to illustrate that you should only work at something you truly love. In fact, hiring someone who does not love his job is also a no-no. Thus, what is it that you can do to discover your passion and calling, meanwhile inspiring others to do the same? The wealth of knowledge is way more valuable if you are working and enjoying what you do on a daily basis. So you can see that both Twain and Thoreau are critics of basic American belief systems. Twain is arguing that there is no such thing as an original opinion about anything. Thoreau argues, that there has never been a time when man wasn’t forced to believe in some kind of conformity, such as you must earn a wage by working. The writers’ had similar writing styles and used vivid descriptions to illustrate their points. In addition, both Thoreau and Twain were great observers of man and the world around him. Thoreau seems to be more concerned with separating himself from mankind in search of the meaning of life. Twain seems to want to focus on man and the uncanny ability to follow the leader. Either way, both Corn-Pone Opinions and Life without Principle, make you want to question the why in life. How to cite Human Nature By Mark Twain, Papers

Blaise Pascal free essay sample

Born: 19 June 1623 in Clermont ( now Clermont-Ferrand ) , Auvergne, France Died: 19 Aug 1662 in Paris, France Blaise Pascal was the 3rd of # 201 ; tienne Pascal s kids and his lone boy. Blaise s female parent died when he was merely three old ages old. In 1632 the Pascal household, # 201 ; tienne and his four kids, left Clermont and settled in Paris. Blaise Pascal s male parent had irregular educational positions and decided to learn his boy himself. # 201 ; tienne Pascal decided that Blaise was non to analyze mathematics before the age of 15 and all mathematics texts were removed from their house. Blaise nevertheless, his wonder raised by this, started to work on geometry himself at the age of 12. He discovered that the amount of the angles of a trigon are two right angles and, when his male parent found out, he relented and allowed Blaise a transcript of Euclid. At the age of 14 Blaise Pascal started to attach to his male parent to Mersenne s meetings. Mersenne belonged to the spiritual order of the Minims, and his cell in Paris was a frequent meeting topographic point for Gassendi, Roberval, Carcavi, Auzout, Mydorge, Mylon, Desargues and others. Soon, surely by the clip he was 15, Blaise came to look up to the work of Desargues. At the age of 16, Pascal presented a individual piece of paper to one of Mersenne s meetings in June 1639. It contained a figure of projective geometry theorems, including Pascal s mysterious hexagon. In December 1639 the Pascal household left Paris to populate in Rouen where # 201 ; tienne had been appointed as a revenue enhancement aggregator for Upper Normandy. Shortly after settling in Rouen, Blaise had his first work, Essay on Conic Sections published in February 1640. Pascal invented the first digital reckoner to assist his male parent with his work roll uping revenue enhancements. He worked on it for three old ages between 1642 and 1645. The device, called the Pascaline, resembled a mechanical reckoner of the fortiess. This, about surely, makes Pascal the 2nd individual to contrive a mechanical reckoner for Schickard had manufactured one in 1624. There were jobs faced by Pascal in the design of the reckoner which were due to the design of the Gallic currency at that clip. There were 20 colloidal suspensions in a livre and 12 deniers in a colloidal suspension. The system remained in France until 1799 but in Britain a system with similar multiples lasted until 1971. Pascal had to work out much harder proficient jobs to work with this division of the livre into 240 than he would hold had if the division had been 100. However production of the machines started in 1642 but, as Adamson writes in, By 1652 50 paradigms had been produced, but few machines were sold, and industry of Pascal s arithmetical reckoner ceased in that twelvemonth. Events of 1646 were really important for the immature Pascal. In that twelvemonth his male parent injured his leg and had to recover in his house. He was looked after by two immature brothers from a spiritual motion merely outside Rouen. They had a profound consequence on the immature Pascal and he became profoundly spiritual. From about this clip Pascal began a series of experiments on atmospheric force per unit area. By 1647 he had proved to his satisfaction that a vacuity existed. Descartes visited Pascal on 23 September. His visit merely lasted two yearss and the two argued about the vacuity which Descartes did non believe in. Descartes wrote, instead cruelly, in a missive to Huygens after this visit that Pascal has excessively much vacuity in his caput. In August of 1648 Pascal observed that the force per unit area of the atmosphere lessenings with tallness and deduced that a vacuity existed above the ambiance. Descartes wrote to Carcavi in June 1647 about Pascal s experiments stating: It was I who two old ages ago advised him to make it, for although I have non performed it myself, I did non uncertainty of its success In October 1647 Pascal wrote New Experiments Concerning Vacuums which led to differences with a figure of scientists who, like Descartes, did non believe in a vacuity. # 201 ; tienne Pascal died in September 1651 and following this Blaise wrote to one of his sisters giving a deeply Christian significance to decease in general and his male parent s decease in peculiar. His thoughts here were to organize the footing for his ulterior philosophical work Pens # 233 ; Es. From May 1653 Pascal worked on mathematics and natural philosophies composing Treatise on the Equilibrium of Liquids ( 1653 ) in which he explains Pascal s jurisprudence of force per unit area. Adamson writes in: This treatise is a complete lineation of a system of hydrostatics, the first in the history of scientific discipline, it embodies his most typical and of import part to physical theory. He worked on conelike subdivisions and produced of import theorems in projective geometry. In The Generation of Conic Sections ( largely completed by March 1648 but worked on once more in 1653 and 1654 ) Pascal considered conics generated by cardinal projection of a circle. This was meant to be the first portion of a treatise on conics which Pascal neer completed. The work is now lost but Leibniz and Tschirnhaus made notes from it and it is through these notes that a reasonably complete image of the work is now possible. Although Pascal was non the first to analyze the Pascal trigon, his work on the subject in Treatise on the Arithmetical Triangle was the m ost of import on this subject and, through the work of Wallis, Pascal s work on the binomial coefficients was to take Newton to his find of the general binomial theorem for fractional and negative powers. In correspondence with Fermat he laid the foundation for the theory of chance. This correspondence consisted of five letters and occurred in the summer of 1654. They considered the die job, already studied by Cardan, and the job of points besides considered by Cardan and, around the same clip, Pacioli and Tartaglia. The die job asks how many times one must throw a brace of die before one expects a dual six while the job of points asks how to split the bets if a game of die is uncomplete. They solved the job of points for a two participant game but did non develop powerful plenty mathematical methods to work out it for three or more participants. Through the period of this correspondence Pascal was unwell. In one of the letters to Fermat written in July 1654 he writes though I am still bedfast, I must state you that yesterday flushing I was given your missive. However, despite his wellness jobs, he worked intensely on scientific and mathematical inquiries until October 1654. Sometime around so he about lost his life in an accident. The Equus caballuss drawing his passenger car bolted and the passenger car was left hanging over a span above the river Seine. Although he was rescued without any physical hurt, it does look that he was much affected psychologically. Not long after he underwent another spiritual experience, on 23 November 1654, and he pledged his life to Christianity. After this clip Pascal made visits to the Jansenist monastery Port-Royal diethylstilbestrols Champs about 30 kilometers south west of Paris. He began to print anon. plants on spiritual subjects, 18 Provincial Letters being published during 1656 and early 1657. These were written in defense mechanism of his friend Antoine Arnauld, an opposition of the Jesuits and a guardian of Jansenism, who was on test before the module of divinity in Paris for his controversial spiritual plants. Pascal s most celebrated work in doctrine is Pens # 233 ; Es, a aggregation of personal ideas on human agony and religion in God which he began in late 1656 and continued to work on during 1657 and 1658. This work contains Pascal s bet which claims to turn out that belief in God is rational with the undermentioned statement. If God does non be, one will lose nil by believing in him, while if he does be, one will lose everything by non believing. With Pascal s bet he uses probabilistic and mathematical statements but his chief decision is that we are compelled to chance His last work was on the cycloid, the curve traced by a point on the perimeter of a rolled circle. In 1658 Pascal started to believe about mathematical jobs once more as he lay awake at dark unable to kip for hurting. He applied Cavalieri s concretion of indivisibles to the job of the country of any section of the cycloid and the Centre of gravitation of any section. He besides solved the jobs of the volume and surface country of the solid of revolution formed by revolving the cycloid about the x-axis. Pascal published a challenge offering two awards for solutions to these jobs to Wren, Laloub # 232 ; rhenium, Leibniz, Huygens, Wallis, Fermat and several other mathematicians. Wallis and Laloub # 232 ; rhenium entered the competition but Laloub # 232 ; rhenium s solution was incorrect and Wallis was besides non successful. Sluze, Ricci, Huygens, Wren and Fermat wholly communicated their finds to Pascal without come ining the competition. Wren had been working on Pascal s challenge and he in bend challenged Pascal, Fermat and Roberval to happen the discharge length, the length of the arch, of the cycloid. Pascal published his ain solutions to his challenge jobs in the Letters to Carcavi. After that clip on he took small involvement in scientific discipline and spent his last old ages giving to the hapless and traveling from church to church in Paris go toing one spiritual service after another. Pascal died at the age of 39 in intense hurting after a malignant growing in his tummy spread to the encephalon. He is described in as: a adult male of little physique with a loud voice and slightly authoritarian mode. he lived most of his grownup life in great hurting. He had ever been in delicate wellness, enduring even in his young person from megrim His character is described as: precocious, pig-headedly persisting, a perfectionist, hard-bitten to the point of strong-arming pitilessness yet seeking to be mild and low In the undermentioned appraisal is given: At one time a physicist, a mathematician, an facile publicizer in the Provinciales Pascal was embarrassed by the really copiousness of his endowments. It has been suggested that it was his excessively concrete bend of head that prevented his detecting the minute concretion, and in some of the Provinciales the cryptic dealingss of human existences with God are treated as if they were a geometrical job. But these considerations are far outweighed by the net income that he drew from the multiplicity of his gifts, his spiritual Hagiographas are strict because of his scientific preparation J J OConnor and E F Robertson

Adamson writes in: This treatise is a complete lineation of a system of hydrostatics, the first in the history of scientific discipline, it embodies his most typical and of import part to physical theory. He worked on conelike subdivisions and produced of import theorems in projective geometry. In The Generation of Conic Sections ( largely completed by March 1648 but worked on once more in 1653 and 1654 ) Pascal considered conics generated by cardinal projection of a circle. This was meant to be the first portion of a treatise on conics which Pascal neer completed. The work is now lost but Leibniz and Tschirnhaus made notes from it and it is through these notes that a reasonably complete image of the work is now possible. Although Pascal was non the first to analyze the Pascal trigon, his work on the subject in Treatise on the Arithmetical Triangle was the m ost of import on this subject and, through the work of Wallis, Pascal s work on the binomial coefficients was to take Newton to his find of the general binomial theorem for fractional and negative powers. In correspondence with Fermat he laid the foundation for the theory of chance. This correspondence consisted of five letters and occurred in the summer of 1654. They considered the die job, already studied by Cardan, and the job of points besides considered by Cardan and, around the same clip, Pacioli and Tartaglia. The die job asks how many times one must throw a brace of die before one expects a dual six while the job of points asks how to split the bets if a game of die is uncomplete. They solved the job of points for a two participant game but did non develop powerful plenty mathematical methods to work out it for three or more participants. Through the period of this correspondence Pascal was unwell. In one of the letters to Fermat written in July 1654 he writes though I am still bedfast, I must state you that yesterday flushing I was given your missive. However, despite his wellness jobs, he worked intensely on scientific and mathematical inquiries until October 1654. Sometime around so he about lost his life in an accident. The Equus caballuss drawing his passenger car bolted and the passenger car was left hanging over a span above the river Seine. Although he was rescued without any physical hurt, it does look that he was much affected psychologically. Not long after he underwent another spiritual experience, on 23 November 1654, and he pledged his life to Christianity. After this clip Pascal made visits to the Jansenist monastery Port-Royal diethylstilbestrols Champs about 30 kilometers south west of Paris. He began to print anon. plants on spiritual subjects, 18 Provincial Letters being published during 1656 and early 1657. These were written in defense mechanism of his friend Antoine Arnauld, an opposition of the Jesuits and a guardian of Jansenism, who was on test before the module of divinity in Paris for his controversial spiritual plants. Pascal s most celebrated work in doctrine is Pens # 233 ; Es, a aggregation of personal ideas on human agony and religion in God which he began in late 1656 and continued to work on during 1657 and 1658. This work contains Pascal s bet which claims to turn out that belief in God is rational with the undermentioned statement. If God does non be, one will lose nil by believing in him, while if he does be, one will lose everything by non believing. With Pascal s bet he uses probabilistic and mathematical statements but his chief decision is that we are compelled to chance His last work was on the cycloid, the curve traced by a point on the perimeter of a rolled circle. In 1658 Pascal started to believe about mathematical jobs once more as he lay awake at dark unable to kip for hurting. He applied Cavalieri s concretion of indivisibles to the job of the country of any section of the cycloid and the Centre of gravitation of any section. He besides solved the jobs of the volume and surface country of the solid of revolution formed by revolving the cycloid about the x-axis. Pascal published a challenge offering two awards for solutions to these jobs to Wren, Laloub # 232 ; rhenium, Leibniz, Huygens, Wallis, Fermat and several other mathematicians. Wallis and Laloub # 232 ; rhenium entered the competition but Laloub # 232 ; rhenium s solution was incorrect and Wallis was besides non successful. Sluze, Ricci, Huygens, Wren and Fermat wholly communicated their finds to Pascal without come ining the competition. Wren had been working on Pascal s challenge and he in bend challenged Pascal, Fermat and Roberval to happen the discharge length, the length of the arch, of the cycloid. Pascal published his ain solutions to his challenge jobs in the Letters to Carcavi. After that clip on he took small involvement in scientific discipline and spent his last old ages giving to the hapless and traveling from church to church in Paris go toing one spiritual service after another. Pascal died at the age of 39 in intense hurting after a malignant growing in his tummy spread to the encephalon. He is described in as: a adult male of little physique with a loud voice and slightly authoritarian mode. he lived most of his grownup life in great hurting. He had ever been in delicate wellness, enduring even in his young person from megrim His character is described as: precocious, pig-headedly persisting, a perfectionist, hard-bitten to the point of strong-arming pitilessness yet seeking to be mild and low In the undermentioned appraisal is given: At one time a physicist, a mathematician, an facile publicizer in the Provinciales Pascal was embarrassed by the really copiousness of his endowments. It has been suggested that it was his excessively concrete bend of head that prevented his detecting the minute concretion, and in some of the Provinciales the cryptic dealingss of human existences with God are treated as if they were a geometrical job. But these considerations are far outweighed by the net income that he drew from the multiplicity of his gifts, his spiritual Hagiographas are strict because of his scientific preparation J J OConnor and E F Robertson
