Genetically Modified Foods Essay

The world is slowly running out of food. Impoverished people have nowhere to turn. Biotechnology researchers think they have found a way to reverse the world famine. This way is through genetically modified foods which are foods that come from genetically engineered organisms. Examples of such organisms are sheep, cows, and fish. However, since it is a new invention, it is being met with harsh and legitimate concerns. While it may help the world’s food crisis, it may also do that at the expense of human health. Moreover, In the 90’s in the USA, the Food and Drug Administration decided that genetically modified food was safe and did not require special regulation. They stated that is was, â€Å"not inherently dangerous. † (FDA, 1998). This allowed genetically modified food such as soybean oils and tomatoes to enter the market. There are lots of ideas about the GMF. Some scientists say that it is no harmful affects of GMF and it may be a solution for scarcity of food and even it is healthy. However, some others say that GMFs are dangerous for public health. And It can damage biodiversity. Genetically modified foods may be a good solition to increase the amount of food. The problem is there are lots of people go to sleep hungry everyday and the number of hungry people is getting bigger. And International Food Policy Research Institute state there are â€Å"120 devoloping countries† which are very close to limit of hunger and â€Å"57 of which with a serious or worse hunger situation. (Global Hunger Index, 7) The reason of this hunger is there is not enough food to feed them and because the world population is getting higher but the areas which use in farming are getting smaller. Farmers could not find suitable area to plant their crops. That is why, They have to find a different solution to be productive. Conko argues that biotech agriculture is the method by which we can increase agricultural productivity without resorting to increases in harmful chemical fertilizers, herbicides, and pesticides. In the Genetic Modification it says that genetic modification provides a means to confer resistance to broad-spectrum herbicides into crops where current weed control is considered difficult. In this way, farmers can be more productive and they can get more product on their fields. â€Å"In the United States, in 2002 about 5. 5 million farmers in 145 nations were planting more than 145 million acres worth of GM crops. † (Conko) On the other hand, genetically modified herbicide tolerant crops might have a negative impact on biodiversity. Genetically Modified crops have an impact on birds and insect. A crop plant modified to be toxic to insect pests can have a direct harmful effect on non-target insects if they eat the plant. It can also have an indirect effect by reducing the insects that are a food source for other wildlife, such as farmland birds. Genetically Modified crops that are tolerant to herbicides could also lead to a reduction in weed populations that act as refuges for beneficial insects, and those that are eaten by birds. This process takes time because of this GM crops evaluate as a good solution but it can destroy the biological diversity. And US conservation organization Royal Society,founded in London In 1660 is a learned society for science, support it. They state that the likelihood of the spread of Genetically modified into the wild populations, the risk of superweeds being produced, the impact Genetically modified introductions might have on the colonies of micro organisms living in the soil and how such risks can be assesed and analysed. Also John Innes Centre, Founded in England is an independent centre for research and training in plant and microbial science, state that Monarch butterfly larvae fed only on leaves covered in pollen from Bt corn grew more slowly and suffered higher death rates and pink bollworm fed on cotton producing the Bt toxin. Aphids fed on Genetically Modified potatoes producing a different toxin were also reported to have a harmful effect on ladybirds feeding on the aphids. Genetically Modified crops can be beneficial for health in terms of their food value. Foods include lots of vitamins which are necessary to our body. In early days, our foods were full of vitamins, proteins, carbohydrate and they were occupied with value. However, now there are not enough foods which are full of value. Because there are lots of environmental factors like global warming which causes to summers takes long time, and scarcity of water, and also some pests. These factors effect the crops and farmers have to use pesticide and this cause to decrease food value. And it leads lots of health problems. And the one of the most important health problem is Vitamin A deficiency. This is the cause of at least â€Å"1 million childhood deaths† each year and is â€Å"considered the single most serious cause of blindness amongst children† in the developing countries. â€Å"A possible solution to this problem is the genetic modification of rice. † ( Potrykus, quoted inGenetic Modification) Although GM foods are benefical for the food value, in some circumstances, it can be very harmful for human health. Without too much control eating genetically modified food can be dangerous and it can lead lots of diseases like Eosonophil Myalgia Syndrome. In this debate, the Physicians and Scientists for Responsible Application of Science and Technology, is a website to educate the general public about genetic engineering in general and foods, revealed that After eating a food supplement produced by genetically engineered bacteria, â€Å"37 persons were killed 1500 people were permanently disabled† in the US in a disease called Eosonophil Myalgia Syndrome. It was caused by one or more extremely poisonous substances that unexpectdedly appeared in this food supplement. This accident confirms the predictions of molecular biologists that genetic engineering can cause the appearance of dangerous unexpected substances. As a Conclusion, there are lots of arguments in the GMF. Maybe It can be a solution for lots of problems, maybe it can be invention of the this century. I think, however, without too much researching about GMF we cannot use it to gain profit. Because human health is important than anything. We have to more careful. In the future, After very deep research about the GMF, we can solve the sustanibility problem.

Down Freedom's Main Line Essay Example | Topics and Well Written Essays - 750 words

Down Freedom's Main Line - Essay Example This emphasis on love as the solution gave people an alternative to active resistance. FOR also established the International Fellowship Reconciliation in Holland. FOR also made Non-violent actions against segregation by organizing its supporters and mounting nonviolence campaigns. FOR mainly used Mahatma Gandhi's approaches (Williams, 48). Question 2 The actions of the Four Black Freshmen, also known as the Greensboro Four in 1960 organized sit-ins, which were basically nonviolent protests, against racial segregation. The main purpose of the sit-ins was to spark an increased sentiment at a time when US history was critical. The problem that blacks encountered was racial segregation in all places of the US life (education, job market and in social events). The February 1, 1960 (4:30 pm) underscores the extent of racial segregation that blacks underwent. In the incident, four black university students were not served food and beverage at Woolworth's 132 South Elm Street's store, simpl y because they were black. The white race and the police reacted to the sit-ins by being antagonistic. Question 3 The reason for the formation of the Student Non-violent Coordinating Committee (SNCC) which was formed in 1960 was to protest against racial, social injustices and even the Vietnam War. This group coordinated southern African American college students in nonviolent protests and activities against lunch counter-segregation which followed the Four Black Freshmen sit-ins. SNCC also campaigned to de-segregate voter registration in America, particularly, in the Deep South. All in all, it is accurate to state that the SNCC purposed to bring about social change and emancipation, through civil rights activism. According to Williams, the role of Ella Baker in the development of SNCC was that of helping form, and directing the SCLC (Southern Christian Leadership Conference), under whose auspices, the SNCC operated and existed. Baker (together with Rev. James Lawson) also injected SNCC politics and administration with participatory democracy. Thus, Ella Baker's contributions to SNCC are indispensible (Williams, 61). Question 4 The reasons for the Freedom Rides were to challenge the non-enforcement of the US Supreme Court, on the cases, I. Morgan v. Commonwealth of Virginia, 1946 and Boynton v. Virginia, 1960. In both cases, the US Supreme Court had ruled that the segregation of public buses were unconstitutional but the Southern states ignored the rulings as the federal government failed to make measures to ratify the rulings. The Freedom Riders sought to challenge this status quo by organizing and riding interstate buses in the South. Participants of the rides comprised mixed racial groups, as a way of discounting the local customs and laws which had solidified segregated sittings. Both the Congress of Racial Equality (CORE) and the SNCC sponsored the Freedom Rides. The involvement of the Kennedy Administration in the Freedom Rides cannot also be discounted. Particularly, the Kennedy Administration got involved in the Freedom Rides after the 1961 Jim Crow South incident which deeply ashamed the administration. A mob set one of the Freedom Ride buses on fire, outside Anniston, Ala. the Kennedy Admin

Case Study Review & Questions Example | Topics and Well Written Essays - 1250 words

Review & Questions - Case Study Example Every unit in an organization should perform its responsibilities effectively for an overall favorable outcome. CCT’s customer service agents include one administrative assistant, seven Customer Service Representatives (CSR’s), and the Customer Service Director. These make up the department’s call center. Current customer complaints show that the team is underperforming. This may be due to bad organizational culture or lack of professionalism among workers. The article reveals that the call center may be having too much work to handle. For instance, current high demands for CCT’s services exceed the sustainable capacity that the call center can serve. This is especially in peak periods that have the heaviest call volumes. In a recent internal report, thirty percent of customers who abandoned their call did not call CCT back. Instead, they were lost to competitors (Roberts, 2011, P.3). Hence, it is mandatory for the CCT CEO to find an effective solution to this problem before it gets out of hand. If the call center continues to underperform, the best case scenario is that the majority of its customer base will shift to another organization with better services. This is because the competitors are likely to take advantage of this situation and offer attractive ideas aimed at showing customers, the inefficiency of CCT indirectly. In addition, the worst case scenario is that CCT may face permanent dissolution in the future. If this happens, research shows that it is ultimately impossible for the company to attain the same level of success even if it re-enters the market base. This is especially due to the recession that started in 2008. Thus, the size of this problem is huge. Approaches to quality improvement are diverse. In CCT, the Customer Service department maintains a website that describes its services and the promotional offers that come from time to time. It refers all customers to the call center unit. Furthermore, the call cent er has an Automated Call Distributor (ACD) machine automatically shares incoming calls among the unit’s nine agents. These features prove that the CEO, Syme, was right in concluding that the staff may be ignoring the waiting calls. The other problem was that the company’s organizational framework was not clear. For instance, call center agents did not know if they should log off or not if they had a special project. Alternatives to the problem As an alternative, Customer Care could modify the website such that customers have direct access to the services that they require. This will require upgrading the computer software to a more advanced system with the capacity of sustaining a large database. An example is the customer relationship management software. The advantage is that it will decrease the number of incoming phone calls to the call center. Hence, calling customers will experience lesser time-waits or none at all. It will also ensure that the staff at the call center is not overworked. Hence, customers will experience better service delivery and satisfaction. The disadvantage is that the system upgrade will lead to increased operational costs. It is because online hosting services in the U.S are expensive (Bullen, 2012, P.76). Increased reliance on the website means that the company will have to pay for more data charges than accustomed. Another alternative would be to abolish the website system and implement another way of service

Public communication Essay Example | Topics and Well Written Essays - 2250 words

Public communication - Essay Example However, the nature of the role of public communication is changing in uncertain ways that lead to speculations regarding their role in the effect on the transformation of the democratic process in the contemporary societies. Here we are more concern about the way governments practice public communication and put constraints in it as well as control of the governments of public communication. Constraints and control: The objective of public communication is to transmit messages targeting the public and enabling it to have an overall view, while at the same time is able to retain its distance from the general strategy and the central messages being transmitted by government so that to achieve its goals and policies. It is very much evident that democratic governments are crucially dependent on a sufficient degree of two-way communication and horizontal communication at the grass root level, otherwise, there cannot be consensus building and responsiveness. In the present era of mass media communication such as newspapers, Radio, televisions do have the potential of including practically everybody. The term public means open and available to the public; visible and observable from the public and effectuated in front of it. Thus, the public has to do with publicity and diaphaneity/transparency. In almost every country, public media works under lots of constraints. The most important constraint, the public communication is facing the interference and involvement of governments at most of the level itself. Even in the post totalitarian world effective legal framework protection to media still far from reality and peoples perception about independent public communication as stage-managed. Public communication faces the constraints such as decision-making power over the public communication, which directly connects with the ownership. Ownership may be public ownership combined with public control i.e. not of government but of civil society or public ownership combined with government control or private ownership with decision making at owners discretion or private ownership with decision making in legal framework and a strong cultural tradition concerning professional rights, quality standards etc. In the above types of ownerships governments put constraint on the all except the last one. So framing legal framework with strong traditions, professional ethics can regulate the constraint. Secondly institutional freedom of public

Dyslexia as a learning disorder Assignment Example | Topics and Well Written Essays - 2000 words

Dyslexia as a learning disorder - Assignment Example Several years later, W. Pringle Morgan, a British physician, published a description of a reading-specific learning disorder in a letter to the British Medical Journal. His letter described the case of a boy named Percy who, at age 14, had not yet learned to read, yet he showed normal intelligence and was generally adept at other activities typical of children of that age. It's evident that such children need some peculiar aide. To prove it I'd like to give an example of my little nephew. Andrew is a very smart boy. At the age of five he was able to accomplish complex mathematical tasks. But he couldn't read and all our forces to teach him reading were in vain. He was absolutely happy when somebody was reading him aloud. It took him ten or five minutes to learn by heart a large poem consisting of twenty lines. So we decided that he was too young to read and at school this problem would be solved. But our suppositions have not proved to be correct. Among the children of his lass he was the best in mathematics and the worst in reading. He got bad marks everyday and that made him believe to be stupid. His teacher explained us that he wasn't to identify words and to recognize the sounds that made up words. Having looked into his copy book my aunt saw that he tended to reverse letters and sometimes whole words for example "saw" was written as "was" "b" as "d" etc. Andrew continued to lag behind his peers in reading and writing skills. He hated school because he was always told to be stupid lazy and the worst. Our previously happy boy was close to nervous breakdown. And we decided to consult a doctor. The dyslexia was diagnosed. Well let's continue Andrew's story. At the first visit to doctor Brant his mother was asked about the family's medical and developmental history. Andrew's mother said that her cousin had had the same problem. After that they were said that after the treatm ent Andrew would be doing well at school and would have all chances to make a thoroughly successful career. Andrew's mother was advised to use reading upgrade course and the result was tremendous. Only a month after starting this course my little nephew began to read himself at first syllables and after month and a fortnight he become able to read perfectly without missing or reversing letters. But this great success has come to us not only owing to this program. Andrew's relatives were given a special guide aimed to teach parents right behavior. Nowadays Andrew is a thoroughly successful young man. He's a first year student of the university; he does very well at the university and doesn't remember about his problems at the childhood. He is a real fan of reading. He seems to know everything in the would. dyslexia is a learning disorder. Its underlying cause is believed to be a brain-based condition that influences the ability to read written language. It is identified in individuals who fail to learn to read in the absence of a verbal or nonverbal intellectual impairment, sensory deficit (e.g., a visual deficit or hearing loss), pervasive developmental deficit or a frank neurological impairment. The following conditions are sometimes confused with dyslexia because they can also lead to difficulty reading: Auditory Processing Disorder is a condition that affects the ability to encode auditory information. It can lead to problems with auditory working memory and auditory sequencing. Dyspraxia is a neurological condition characterized by a marked

Perfume Essay Example | Topics and Well Written Essays - 750 words

Perfume - Essay Example Since then perfumes are widely applied in various settings of the sphere. Their role is enormous, ranging from the individual respective, as a consumer learning tool, in mood therapy, in foods, detergents among others (Bennett 49). The broad application of perfumes triggered the researcher to explore their relevance in determining the attitudes of the human organism. The survey used both survey and literature review. The literature review was employed to assist in ascertaining the gap that exists in the study of perfumes and how they elicit moods in humans. Further, the deduction of the literature was vital in determining the current state of affairs, its theories and the developments in the sector. The synthesis of the literature reveals that humans are wired in a way that their sense of smell leads them to automatic approach-avoidance Responses inclusive of general attitudes, emotion and actions. The resultant responses are either positive or negative. Human being search for pleasurable experiences, and they always aim to avoid any painful or negative experiences as per nature. Based on the categorization theory, the study realized that it is possible to break pleasures into forms involving sensory, emotional and social traits (Porcherot 939). The review showed that emotional preferences typically stem from aesthetic stimulation. For instance, the smell of roses can remind one of a pleasant childhood, which arouses good moods in the individual. Sensory pleasances are the simplest forms to comprehend since they involve the pleasures created by sensory contact with outside stimuli. He further argues that Social pleasures arise from contact and interaction with peers. The experiences of persons can involve one form or a mix of the described pleasure types though in the end, individual summaries the experience as a memory that falls into a single
