The Human Of Endangered Species - 1309 Words

The environment has always been one of the primary sources credited for the existence on Earth. The environment has provided the human race and Earth with the essentials needed and more for survival. Both living and nonliving things play a role in continuing the constant cycle that keeps everything maintained and in order. When something as small as a plant or as large as a bear is taken from the cycle of life, there are major effects that occur and bring negative problems. Humans are most likely the ones to blame for endangering these species. But global warming has helped play a part in it as well. Even though the answers to solving the problem on saving endangered species are known and well aware of, not enough of the human has reached†¦show more content†¦These plants are used for curing and preventing illnesses such as malaria, eczema, maintaining blood sugar levels and many more (Shultz). The medical plants along with others become endangered species from overharvestin g and deforestation (Shultz). Plants are not species that can be perfectly artificially created. Most plants that provide resources for humans can only be grown through their natural process in their habitat. Now as for as animals, most can easily relocate when they are forced out of their natural habitat. But relocation does not always bring good results. Animals need food, fresh water, and a place to raise the young. But well fit homes are becoming scarce. Pollution and human overpopulation is making it harder for certain animals to find a decent habitat. Hunting and deforestation is making it harder for elephants, tigers, fishes, and many more to breed at a pace to help save the species. These animals are being placed on the critical endangered species list because of the rapid rate of extinction. The human race has become so obsessed with tusks, furs, and the value on the market for the animals that they are overlooking the dangers from their greed. If an animal is considered to have a prize possession it becomes in some cases it becomes a victim to poaching. Poaching is illegally killing a creature for something that it has. The animal is left die after being degraded. Animals born w ith valuable features, end up being endangered from

Hemingway Essay Example For Students

Hemingway Essay Ernest Hemingway’s tough, Terse prose and short, declarative sentences did more to change the style of written English that any other writing in the twentieth century. II. Ernest Hemingway has had many great accomplishments in his historical life but just one event has hardly sticks out from the rest. The Old Man and the Sea is one of Hemingway’s most enduring works. Told in Language of great simplicity and power, it is the story of an old Cuban fisherman, agonizing battle with a giant marlin far out in the Gulf Stream. Here Hemingway recasts, in strikingly contemporary style, the classic theme of courage in the face of defeat, of personal triumph won from loss. Written in 1952, this hugely successful novel confirmed his power and presence in the literacy world and played a large part in his winning the 1954 Nobel Prize for Literature. This novel also won the Pulitzer Prize award. III. July 21st, 1899, Ernest Hemingway was born. He was born to DR Clarence Edmonds and Gr ace Hall Hemingway. He grew up in a small conservative town called Oak Park, Illinois. His father, a practicing doctor, taught him how to hunt and fish, while his mother, wished to make him a professional musician. His upbringing was very conservative and somewhat religious. He attended Oak Park and River Forest High School, where he distinguished himself in English. His main activities where swimming, boxing, and of course writing. In 1917, turning his back on University, he decided to move to booming Kansas City where he got a job as a cub reporter on the Kansas City Star. At the train station, his father, who later on disgusted Ernest by committing suicide, kissed his son tenderly good-bye with tears in his eyes. This moment was eventually captured in For Whom the Bell Tolls. Hemingway wrote that he felt so much older than his father that he could hardly bear it. The Star was the first to introduce Ernest to news writing which demands brief, to the point sentences, that contain a smooth easy following of ideas. He would later adapt this style to his fiction. In May of 1918, Hemingway became an honorary second lieutenant in the Red Cross. He could not join the army due to a defective left eye (resentfully inherited from his mother). On his first day of service across seas, he and other ambulance drivers were assigned the horrific duty of picking up body parts from an exploded munitions factory. Death, mostly of women, on such a scale was most definitely another very shocking moment in Hemingways young life. But he soon recovered from this experience and became known as the man who was always where the action is. He would often sneak cigarettes and chocolate to soldiers on the Italian front. It was on one of these occasions that he was severely wounded by an Austrian trench mortar. Even with over a hundred pieces of shrapnel and an Austrian machine gun bullet logged in his leg he managed to carry a wounded soldier a hundred yards to safety. He got the Italian Medal of Valor for his courageous action. He spent his recovery time at the Ospedale Croce Rossa Americana, in Milan. It is there that he met and fell for a thirty year-old nurse called Agnes Hannah. To Ernests disappointment, Agnes was not willing to embark in a relationship. Ernest, who had not yet turned twenty, who was a war hero, a journalist and a wounded soldier, was too young for beautiful Agnes . With the will to write fiction, he moved to Chicago where most of his work was refused. He lived by writing for the Toronto Star and working as a sparing partner for boxers. It was in Chicago that Hemingway met Elizabeth Hadley Richardson. She was an innocent young woman with graceful features and a strong attraction for the eight year younger Hemingway. Not having much income and wanting to marry Hadley, Ernest chose to move to Paris. Hemingway managed to convince the Toronto Star to accept a series of Letters from Europe. The young couple also received money from Hadleys trust f und while Ernest continued to work as a sparing partner for boxers. In Paris, Hemingway encountered many of the greats (historically known as The Expatriates). He met Gertrude Stein, Ezra Pound, James Joyce, Scott Fitzgerald , Ford Madox Ford and John Dos Passos. It was Stein who took him under her wing. She had been working to renew literary writing by removing useless gothic, Victorian and archaic forms. She was the first to point Hemingway in the direction of the simple declarative sentence, an attempt to make words communicate concretely and efficiently. It was also during this period of his life that Hemingway discovered the bull fight, the Pamplona bull run and the famous San Fermin July Fiesta. He would later write several books and short stories about bull fighting and the many events that surround this tragic ritual. Among these are Death in the Afternoon and The Dangerous Summer. Quickly after Patricks birth, they moved on to what would remain Hemingways only true residenc e in the United States Key West, Florida. It was there that a whole new world broke itself open to the sportsman in Ernest. Fishing the deep sea for great fish like the tarpon and the barracuda was his newest love. But even in Key West, a heavenly earth, tragedy struck Ernest. His father, struggling with diabetes and angina pectoris, had put a bullet through his head. Hemingway was very ashamed of this. He had always felt that life was for the testing of death. Suicide was the surrendering of life to death. This was forbidden in his code of courage. From that day on, Ernest turned his back on his father. 1929 marked the release of A Farewell to Arms. It was instantly accepted as a great work by critics and the public. With the success of this novel, Hemingway became a true American writer. To many, he also became a hot headed fool. He would make loud remarks about some of his fellow writers. He would make proclamations about artistic integrity that he himself would often not respect . He clearly was no longer the shy young journalist he had been for the Kansas City Star. He had become Papa. Even with the beautiful surroundings of the Key West, Hemingway still longed for Spain. At the time he was tediously working on Death in the Afternoon, a marvelous, intriguing and powerful look at the bullfight. Although at times overdone, Death in the Afternoon will capture greatness and power in the minds of its readers, even those that are most disgusted by the bullfight. After Ernest finished Death in the Afternoon and Pauline gave birth to another boy, they set off for Africa. It was there that Hemingway hopped to find the true meaning of heroism. Three stories would result from the events of Africa. The Green Hills of Africa, which lacked effective meaning and carried a false tone of masculine hunting spirit, was the least successful. The Snows of Kilamanjaro was a much more potent tale about the hunt. Arguably one of Hemingways best, it drew from the troubles of a bro ken Scott Fitzgerald to depict the guilt of a talented yet unacomplished artist as he faced death. The last short story to result from Africa was The Short and Happy Life of Francis Macomber, which seeks the meaning of courage. The Spanish Civil War became official in July, 1936. Hemingway was offered a liaisons job by the North American Newspaper Alliance (NANA). He accepted, much to Paulines opposition. Being a newsman, officially he remained neutral throughout the war. Despite this, Hemingway could often be overheard raising funds at social gatherings in America to fight the fascists back in Spain. In 1940, after the end of the Spanish Civil war Hemingway published For Whom the Bell Tolls. His long divorce with Pauline came to an end, and he married Martha Gellhorn. This would turn out to be the shortest and least understandable of his four marriages. During the Second World War, he equipped the Pilar with grenades and sub conning towers for the purpose of hunting Nazi submarines . This got it recognized as an official Q-ship. Of course its unshaven crooked crew never sunk a sub, they simply spent their days fishing off the Cuban coast. Martha, who was very involved in the war, was as always quick to criticize Ernest. She accused his personal navy of fraudulent use of gasoline rations. One night, when returning form a drunken party, Hemingway had a severe car accident. He was hospitalized with serious head trauma . Martha returned from the front to see him. Instead of comforting the banged up Ernest, she simply laughed at his sad state as he lay in the hospital. In June 1944, Hemingway finally set foot in Normandy. He made his way to the front, compiling a small army of undesirables by his side. With his small guerrilla force and a few bottles of scotch Hemingway marched in to Paris on the 25th of August, five days before the city was officially freed. He proceeded, by his own authority, to liberate the Travelers Club and the Ritz, in which he took a room as well as the bar. He was eventually awarded the Bronze Star for his part in the invasion. On another occasion, while Mary was staying with him at the Ritz, he shot a portrait of her husband. He placed the frame over the toilette in his room at the Ritz and discharged his hand gun into it. This flooded the room and several floors below it. Mary got a taste of Hemingways madness. Yet, in 1946, they were married. The war was over and they returned happily to La Finca. Across the River and into the Trees was the fist of a fictional three part saga about earth, sea and air. It takes place in Venice. It is about an old soldier, who is no longer at war and who falls for the sweet beauty of the much younger contessa Renata. Some said that this novel had a strong Shakespearean quality, many others only saw a pathetic tale about an old man infatuate with a young lady. Hemingway outdoes himself with charming descriptions of Venice in this book. Yet he fails in making his protagonist soldier sy mpathetic, a sign that he was self-conscious of his boisterous behavior. This book marked a turning point in Hemingways life, it stood for his passage into middle age, something he had not been willing to accept easily. In 1950, after having been dubbed as a burnout, Hemingway put himself to work on his greatest story ever. The Old Man and the Sea was published in 1952. It was a very touching tale about an old man who finds grandness of life and death while battling the great marlin. He is ready to heal down before the fish, when it finally gives in. While towing the animal back to shore, its beauty is destroyed by sharks. The humility of the old man, his handshake with grandeur, all make this tale truly beautiful. The Old Man and the Sea was Hemingways second entry in his triad about land, seas, and air. It got him the Pulitzer Prize, and in 1954, the greatest literary award of all, the Nobel Prize. Hemingway had three true phobias in his life: telephone conversations, the taxman, and public speaking. Yet he wrote a very touching speech that was read. It was at that moment that the end had begun for Papa Hemingway. Before the Nobel Prize in 1954, Ernest and Mary had sought out his fifth African safari. This time he was much less boisterous. He maintained a clear mind. He shot very well, and demonstrated great ability. Yet the safari ended badly with two plane crashes. The first had not been too serious. The second, although, had distraught Hemingway quit badly. His injuries included concussion, paralysis of the sphincter, first degree burns on his face, arm and head, a sprained right arm and shoulder, a crushed vertebra, and a ruptured liver, spleen and kidney. He was in continuos pain for quite a while. It was in Pamplona that Hemingway celebrated his sixtieth birthday. Mary had spent two months preparing for the event. She ordered champagne from Paris, Chinese foods from London, codfish from Madrid. She hired a shooting booth, fireworks specialist, flamenco dancers, waiters, barmen and cooks from all over the world. Guests included General C.T. Lanham from Washington, Ernests old Paris pals, Italian Royalty and the Maharajah of Behar. The party went twenty-four hours strait, from noon of July 21st to noon July 22nd. Seeking a calm place to recuperate and continue work on The Dangerous Summer, Ernest and Mary relocated to their cabin in Ketchum. But for Hemingway, Idaho was a far cry from the comforts of Cuba. His eyes were failing him to the point of not being able to write anymore. Even if he did manage to put down words, they often were incoherent, lacking any logical meaning. He could not drink anymore due to his kidney injury. Slowly but surely Ernest degenerated physically and psychologically. Even while still living in Cuba, Ernest began showing signs of paranoia and delusion. He would often say that FBI agents were following him. Although he had large enough savings to cover any immediate financial problems, he was constantly a fraid of being hunted down by the IRS for tax evasion. It soon became evident to those around him that psychiatric help would be necessary. They managed to convince Ernest to institutionalize himself. Fearing he would refuse, it was agreed upon to tell him that the treatment was for his high blood pressure (Hemingway had always been wary of his blood pressure). On November 30th in 1960, Ernest Hemingway was committed to the Mayo Clinic in Rochester, Minnesota. During the month of December he was given electroshock therapy. In January of 1961, Ernest was released. At first all seemed well again. He had even managed to write a few coherent words for the jacket of George Plimptons new book: On April 23rd, Ernest Hemingway tried to take his life for the first time. He had tried to put a shotgun to his head. It had failed the first time but he then later went on to put that one tragic bullet in his head. IV. My opinion of this book is phenomenal. It taught me a sensational amount of inte resting facts about Ernest Hemingway. He went through so much in his life. A lot of events in his life interested me which made me keep on reading the book! Hemingway had may happy events but yet he went through some really hard times. All this added up in which he followed in his father’s foot steps and killed himself. Overall Ernest Hemingway should be a world figure for his excellence and commitment to writing. V. V. 1. In 1926 Ernest wrote the novel The Sun Also Rises. 2.

Frees - Sarcasm and Irony in A Modest Propos Essay Santiago, the main character in the story, does not divulge in any pleasures what so ever. It almost seems as though he is trying to make himself suffer. Everyday, Santiago hardly eats anything but a little fish or coffee. He does not have any relationships with women in the story, as many Hemingway novels have included. While Santiago is out on the boat, he does not let himself stray from the task at hand even though it is very uncomfortable. The Hemingway code hero would be the exact opposite of Santiago. He would eat large meals every day, make love to many women, and never put himself in a position that he did not like. The code hero would do everything as though it was the last time he was doing it because he did not believe strongly in the presence of God. Santiago was different because he believed in God, and prayed to him for help throughout the story. While he was at sea, he often prayed that he would get the fish or that he would live to see the fish brought to the village. Santiago did not fear death and the reader senses that Santiago believes that if he dies, he will go to heaven. The story is also filled with many biblical references and the whole book has a religious theme. Hemingway does not usually have his code heroes be religious, and most of them feel that they only have this time on earth and they had better make the best out of it. Finally , Hemingways code hero differs in The Old Man and the Sea because of the presence of the boy that is Santiagos companion. Known only as the boy, he is constant throughout the novel as Santiagos student, who takes care of Santiago. It seems that everything that Santiago does is for the boy, and not himself. In the normal code hero, the hero would do everything for the benefit of himself and for no one else. The hero is usually not a fatherly, gentle figure, but a robust, energetic manly man. Therefore, it can be seen that Santiago is different than other Hemingway characters because of the distinct actions he made. And although Santiago does not meet the standards of the Hemingway code hero, it is his disinterest in physical pleasures, his need for a companion, and the presence of religion that makes him a special hero in his own right.

The purpose of the dictionary is to set forth the orthography, pronunciation and signification of those words. The thesaurus, on the other hand, is a specific dictionary that presents synonyms (words that have similar meaning) for every word listed. This type of dictionary became famous after its integration with word processing software. The purpose of the thesaurus is to help the writer to find more suitable words and avoid the repetition of terms. Online Dictionary and Thesaurus Thankfully you no longer need to visit a library to get access to a good dictionary or thesaurus. There are plenty of websites that offer those resources free of charge. Dictionary.com is one of the oldest and most reliable online dictionaries. On the same website you will also find a link to the sister site Thesaurus.com. Merriam-Webster, one of the most famous dictionaries around the world, also offer an online version.

Tourism impacts and sustainability Essay Example | Topics and Well Written Essays - 2500 words

Tourism impacts and sustainability - Essay Example According to the journal Tourism by Tourism Alliance, the impacts of tourism activities are innumerable. The effects of tourism comprises of the social, cultural, political, and economic. The United Kingdom has put prudent strategies to address the possible adverse impacts of tourism. This is in the light that tourism can disrupt environment, culture, and economy in the regions of its occurrence. The principal aim of sustainable tourism is to maximise the positive development and experience of the people where it takes place. To achieve tourism sustainability, this calls for managers and all the stakeholders to cooperate. The result is to streamline the tourism industry for maximum benefit of tourism industry (Tourism Alliance, 2010:3). This paper will endeavour to examine the impact of tourism and its sustainability. The paper will achieve this objective through looking at a number of studies in academic journals. According to ADAS report, tourism contributes to the growth of econom y of the United Kingdom. The department for environment, Food, and Rural Affairs in conjunction with Tourism Company and ADAS did a research on the trends of tourism in the year 2007. The research was seeking to find evidence, trends, and performance in the tourism industry. ... Moreover, the report portrays that the United Kingdom spends many funds on global tourism (Defra, 2007:5). The ADAS research further reveals that the ever-growing air transport has facilitated the growth of tourism. The findings allude that in the United Kingdom is one of the biggest earners from the international tourism. The report shows that in the year 2005, the United Kingdom ranked fifth in the rank of the largest nation with highest incomes from tourism. On the aspect of adverse effects of tourism on environment, the ADAS research does not find any connection to link tourism with ecological degradation. This is an allusion that tourists’ activities do not have any adverse effects on the environment (Defra 2007:8). Haley, Snaith, and Miller’s research presented in their journal asserts that a smooth interaction of tourists and local communities is important for sustainable tourism. This is from their case study at Bath in the United Kingdom in 2004. The main inten tion of the study was determine the perception of the people of Bath towards tourism. Using a sample of people and longitudinal and comparative data collection, the report indicates that people support tourism development in Bath. The findings of this research demonstrate that tourism does not have any adverse effects to the social settings in the United Kingdom. There research highlights that the residents of Bath embrace tourists’ activities and development. According to the research, some of the factors that accounts for the support of Bath for tourists destination include low incomes. The people of Bath encourage tourists’ activities as a source of income. This is because of the benefits they obtain from tourists activities. Much of the findings in this study indicate that

Testing Liquids for polarity Essay Example for Free

Testing Liquids for polarity Essay Results and Observations: Liquids Results Shape of molecule or Lewis Structure Conclusions Distilled Water 4 cm of deflection The water molecule is very polar. This is because the only oxygen in the molecule is left with 2 lone pairs which give as a result an enormous negative center. On the other hand, the two H atoms are positive resulting into a very polar molecule. As a result, the stream of distilled water has a quite large deflection which almost went out of the beaker. Heptane 2 mm of deflection The deflection is very small, almost impossible to detect. Because of this we can conclude that this molecule is non-polar as no attraction towards the charged ruler is shown. Ethanol 3 to 4 cms of deflection In this case, the deflection of the stream is bigger and more obvious to human eye. As we can see in the structure of the molecule, the oxygen atom is left with 1 lone pair which makes it into a medium size negative center. However all the carbons and the hydrogen atoms in the left of the oxygen exert a positive charge bigger than the negative charge which makes it polar. However although there is polarity, the stream isnt deflected so much. Propanol 3 cm of deflection Although the structure of this molecule is quite similar to the one of HEPTANE, in the case of PROPANOL, we can see an oxygen atom which again is left with 1 lone pair1 which creates a negative center in the right of the molecule. However, this negativity is balanced thanks to the C and H atoms in the left. This is way this molecule is polar but not enough to deflect the stream so much. This is why it shows a medium deflection of 3 cms. Propanone 2 cm of deflection This molecule shows as very weak polarity because the only way of this molecule being polar is the double bonded Oxygen-Carbon bond. Oxygen is more electronegative than carbon which gives as a result a very weakly charged dipole. In conclusion, the stream wont deflect a lot. Ethanoic Acid 5 cm of deflection In the case of this molecule, we can see 2 O atoms which in total are left with 3 lone pairs which create a gigantic negative center. The rest of the atoms of the molecule arent capable of dealing with these forces so the molecule turns out extremely polar. This is why we can see a very big deflection in this case. Ethyl acetate 3 cm of deflection This is a moderately polar molecule which shows a medium deflection of the stream. This is because although it has 2 O atoms one of them located on the top of the molecule, the lone pairs of these O atoms cant exert that big amount of negative force as to create a very polar molecule. Another factor is the presence of H and C atoms in both sides of the O atoms which balance the forces of the lone pairs. In conclusion, although its a polar molecule, due to the position of the O atoms and the H and C atoms, Ethyl Acetate didnt deflected that much the stream Ethane-1,2-diol 4 to 5 cms of deflection This molecule is clearly polar because of the great deflection that is caused by it. There are two O atoms each one with a lone pair which creates a very powerful negative center which makes the molecule to be polar. Increasing Order of Polarity Downwards HEPTANE PROPANONE PROPANOL ETHYL ACETATE ETHANOL DISTILLED WATER ETHANE-1,2-DIOL ETHANOIC ACID Camilo Lovera Trujillo Testing Liquids for polarity Evaluation / Improvements: Limitations / Errors Improvements * Bad smell of substances. * Many of the substances we were working with, had a very strong and bad odor which spread all the way over the class. Due to this smell, many of the students found difficult to concentrate and to be able to record correctly the deflection of the streams. Its better if the students wear any type of mask or mouth covering so that focusing of students isnt affected by the smell. * Electrically-charged rod * For being able to deflect the stream of the substances it was necessary to have an electrically charged rod which could attract the stream However, is difficult to keep a fair test in charging the rule or the rod because it was possible that in some cases, the rod was more charged than others. A possible solution to this is to change the rod for a magnet or and object which is already magnetized so that the same attraction force is kept during all the experiment and no possible inaccuracy in the deflection of the streams can happen. * Deflection * The deflection, in some cases, was difficult to record. Unfortunately, we had no instrument to measure the deflection but our own eyes. It was possible to use the ruler but it was also very difficult as everything happened very fast. Due to this, there might be some inaccuracy in the results as they were recorded with what we saw and estimated to be the deflection. Maybe a way to help recording more accurately the information is to use instead of a beaker, a kind of deep transparent tray placed over a ruler so that is easier to measure the deflection Camilo Lovera Trujillo Testing Liquids for polarity Conclusion: In conclusion, this practical helped us to find the relationships between the Lewis structure or the molecule structure and the deflection the substances caused when they were near to an electrically-charged rod. From the observations and results we can also conclude that the C atoms reduce the polarity of the molecules as they created positive center in the molecule. However, it was thanks to the O atoms n most of the molecules that their polarity was considerably increased as they were left with lone pairs which helped to create negative center even bigger than the positive ones and due to this, deflect more the streams. On the other hand, theres a final conclusion to be made and is about the order of the polarity. Acids are the most polar substances just after the amides. In the case of Ethanoic Acid, we can see that it makes part of the most polar substances tested in this experiment as a result of the H bondings and the presence of the 2 atoms of O. Going down the list we will f ind: Alcohols, Ketones, Aldehydes, Amines, Esters, Ethers and Alkanes.
