The Omnivore Dilemma Part One Summary free essay sample

Industrial/Corn Summary The Omnivore’s Dilemma, by Michael Pollan, analyzes the eating habits and food chains of modern America in an attempt to bring readers closer to the origin of their foods. Pollan’s blend of humor and philosophical questions about the nature of food serves both to enlighten readers about the environment from which their food is harvested and to teach readers about alternative ways of eating. In the first chapter of Omnivore’s Dilemma by Michael Pollan, we are introduced to the topic of industrial corn and its origins some thousands of years ago. Originally known as â€Å"Zea Mays†, corn started off slow in biological terms but blew up after the discovery of Christopher Columbus. Now that there was corn the settlers were free from the Natives and could now support themselves on the agriculture of corn. Now in modern times we have created new types of corns to feed humans and animals but also to create over 25000 products in supermarkets today. We will write a custom essay sample on The Omnivore Dilemma: Part One Summary or any similar topic specifically for you Do Not WasteYour Time HIRE WRITER Only 13.90 / page Pallon mentions in Chapter one the differences between American and Mexican diets. Stating that the Mexican diet is that of a corn-based nature, where as Americans is on the other side of the spectrum eating more meats than anything. In truth it’s the opposite, it’s the Americans that are eating more corn. It all comes down to the way we feed our animals and process our foods. Americans feed their livestock with corn, and pump corn-based products into readily available food. Whereas Mexicans although they eat a wide variety of corn and grains still feed their animals with grass and sweeten with sugar cane versus corn-based sweeteners. So the Americans really do beat out the â€Å"Corn walkers†, I guess you could say they’re walking corn from the high levels of corn consumption. Pollan pulled me into chapter one with the information he provided about corn. I was enlightened by this chapter and decided to do some research of my own. I started looking into several different food and products that are corn based and animals that are corn fed. For example, corn feeds the steer, chicken, pig, turkey, lamb, and some fish, we eat; corn is in processed foods, like a chicken nugget contains corn starch, corn flour, corn oil, as well as lecithin, mono-di- and tri-glycerides, and citric acid, which all contain corn; Corn is contained in soft and fruit drinks, alcohol, mayonnaise, mustard, margarine, salad dressing, cereal, toothpaste, cosmetics, disposable diapers, trash bags, cleaners, matches, batteries, magazine covers, linoleum, fiberglass, wallboard and gasoline (ethanol). Needless to say, corn is everywhere! In chapter two, Pollan visits a small farmer in Iowa owned by George Naylor. Most of the 470 acre farm is used to grow corn, to ensure a high yield rate for the season. While at the farm Pollan sets out to understand the mysteries of the Industrial Corn world and to get an in depth look at the life of a farmer’s life after corn surpluses have been put in. Last, in chapter three, Pollan visits the great grain elevator not far from the Naylor farm in Iowa. He goes in-depth with the governments funding and the living of a farmer on the subsidies. To be perfectly honest, I was expecting â€Å"The Omnivore’s Dilemma† to be boring, overly written and full of words I could not only pronounce but did not know the meaning of but I found it to be well defined and though out in terms of the structure and sentence transitions. Many writers attempt to grab the reader’s attention with over-inflated words, when a simple description is adequate, and quite sufficient to convey the though, idea, or concept, that the book is about. I was thrilled reading about corn, which was not expected, and it made reading the book that much more enjoyable.

Global Race for Energy

Global Race for Energy Introduction The struggle for energy ownership, control, and power among the rich states in the world is currently intensive. Examples of these energy-producing substances include oil and gas, which have become a major topic for debate all over the world. The reason why this war is taking place could be the speed by which the scarcity of these energy substances is extending worldwide.Advertising We will write a custom essay sample on Global Race for Energy specifically for you for only $16.05 $11/page Learn More This scarcity is also introducing a different and new world form, such that, while some nations are fighting for energy power, others are in the race trying to secure the energy. For example, states like the US and EU nations have started to be involved in discussions, with the main objective being to address international future for energy and its advantages. Indeed, debates concerning the current and future energy requirement are among the challeng ing issues in the contemporary world. Some of the key supply areas for oil and gas today; and how is that geography changing These areas are the key points in which the whole issue is surrounding. Saudi Arabia is the largest producer of oil; the U.S comes second in production but the highest in terms of consumption (Mtsiva, 2) and China is the second highest consumer of energy after the U.S. This seems to be the initiation mark of the global race for un-renewable sources of energy (Belkin, 5). This production and consumption has however caused changes in geographical marketing and supply. For example, the U.S market was left depending on minor oil producing companies when bigger oil companies turned their businesses abroad, looking for larger market and suitable place for their investment (Mtsiva, 3) During the times of ancient world war, most of the nations depended primarily on market capacities of private companies and international oil companies for sufficient supply of energy. However, this is not true in contemporary world because the high rates of economic growth have triggered better policymaking, especially in high population countries like India, Brazil, and China. Other major predominant suppliers of energy to the European Union (EU) nations are Russia, India, Norway, Middle East, and North Africa (Cabral, Para 4). How do the industrial states work to secure oil and gas supplies through non-market means? This energy business has suffered security risk and scares in major industrial states in the past. In such tense conditions, agreement on better security agenda for energy sector becomes difficult, especially when some states decide to pursue their own interests (Korrin and luft, 335).Advertising Looking for essay on business economics? Let's see if we can help you! Get your first paper with 15% OFF Learn More There is a probability of energy-hungry nations to focus on their own economy, security, and environmental concerns in the process of securing energy (Korrin and luft, 357). As it has become more difficult to obtain oil and gas, countries are trying to create more energy sources other than geographical varieties (Korrin and luft, 337) Some countries like the U.S have developed a policy that aims at maintaining national security in the oil market. A national security is a form of social cost that can justify government actions in oil markets but not loan guarantees on economic grounds (Mtsiva, 78). Moreover, a policy concerned with tax incentives has enabled reduction of tax penalties and expansion of oil and gas tax incentives (Mtsiva, 79). Some countries have tried to form collaborative partnership; for example, partnership between China and the U.S has brought a number of benefits between the two nations. Already, a ten-year plan was set up in 2007 by top government and economic officials between the two countries, that is, the U.S Department of Energy and China’s National Development an d Reform commission (Cabral, Para 13). In the EU nation, energy security increase has been minimized by occasional debate on liberalization and market integration in their agenda. The commission has decided on development of Europe-wide internal market for gas, network interconnection, and assessment of market (Belkin, 25) The effect on countries supplying oil and gas do they prosper or suffer? Most of the countries supplying these sources of energy are countries with good economic standards like the U.S and the EU nations, although there are some countries that are still struggling in economic issues but still can supply energy. These countries have already established themselves in terms of collaborative partnership, policies transformation, and procurement of energy. Therefore, subjectively, if a country engages with another nation in securing oil market, then that country is not suffering, as this collaboration brings a sort of socioeconomic sustenance. However, if any nation p uts its concerns alone, then eventually it will start suffering due to lack of foreign investment (Cabral, Para16). Conclusion The whole world’s nations need to join hands together in solving this major crisis in energy market. If each country creates policies that control its energy market in production, supply, and consumption strategies, then insecurity will definitely be eliminated in the market. The engagement in collaboration and networking is also a good idea in energy market. Nevertheless, foreign investment and interrelation between different countries helps to reduce the economic gap between the rich and poor countries.Advertising We will write a custom essay sample on Global Race for Energy specifically for you for only $16.05 $11/page Learn More Belkin, Paul. â€Å"The European Union’s Energy Security Challenges.† CRS report for Congress, 2008.

The Main Ideas of the Bush Doctrine Essay Example | Topics and Well Written Essays - 1750 words

The Main Ideas of the Bush Doctrine - Essay Example The first principle relates to rejection of moral equivalency concerning international affairs, whereby the Bush Doctrine contends that there is a need for moral judgment in international affairs; In fact, the Bush Doctrine asserts that liberal democratic regimes are superior to tyrannies1. The other principle of Bush Doctrine concerns the repudiation of social work concerning the theory of terrorism, and belief of economic factors such as poverty and hunger that are regarded to be the cause of the phenomenon. In fact, Bush Doctrine is based on the assertion that terrorism led to 9/11 and precursors that were both against United States and Israel as a way of destroying western liberalism2. Moreover, this ideology is considered dangerous like fascism and communism, which prevailed during the Second World War3. Therefore, this doctrine is also considered the source of 9/11, and the aggression related to culture of tyranny that prevails in the Middle East, and generates fanatics, aggres siveness, and religious despotism. The other principle relates to recognition that after terrorism attack in September 11 conventional approaches to threats, suppression and preclusion and responses of ex post where rendered insufficient. Therefore, inadequacy prevailed in situations requiring efforts to deal with terrorism and rouge regime seeking to weapons of mass destruction. Bush Doctrine gave the rights to undertake preventive war to United States, and the international laws and norms, which embraces the right of a nation to launch strike to another nation that is imminent, hence rejecting the right of preventive war4. Bush doctrine was also considered an innovation attributed to neo-conservatism; hence, it was historical, whereby it can be described as a fusing power of America to principles that ensures the survival of principles and propagation for the benefits of the human beings. The doctrine also applies to American statecraft from the foundation of the Republic since; t he principles of America are founding and significant for determining the foreign policies in U.S.A. Nonetheless, there are implications of the argument relates to linear progression from pronouncement of sovereignty by Bush as an attempt to initiate democratization process in Iraq. Iraq War in 2003 as the ultimate test of the Doctrine in practice The war in Iraq was a definitive test for the Bush Doctrine in practice, since it was initiated through a justified invasion that was in accordance with the doctrine of â€Å"pre-emption†, which refers to prevention of terrorist attack upon America. There was an assertion that the regime in Iraq was in possession of weapons of mass destruction, which were likely to be applied in as chemical weapons, to be sold to terrorist such as al Qeada5. Nevertheless, Iraq has been a primary example of rivalry towards American as the most critical part of the world since the Gulf war, though there are efforts by Americans to alter the situation with a global strategy6. In fact, the change of Iraq regime was justified as morally and pre-emptive act aim at defending Americans, through the intention was considered geo-political, whereby controlling the most significant Arab nation and its oil resources7. This gave United States significant power as a nation and beyond other nations in Europe, central Asia and China. The other practical aspect of Bush doctrine was portrayed through neo-conservatism vision of foreign policy in

Debate whether downloading of music through the internet is ethical or not Essay Example for Free

Debate whether downloading of music through the internet is ethical or not Essay Music is one of the countless arts that represent the world as it is and sometimes much better- what it should be. Aside from this cliche, the world of music is being torn between legal issues of piracy and what others claim to be the inherent natural rights of individuals who would want to listen to music- free access. The internet provides one of the most free access portals for those who would want to have the music of their choice, but the question remains- is it ethical to get something for free when it is legally established to have a tendering value? In more simple terms- is it ethical to steal music online? Joseph, Francis, Angelo, Kairos, Karina and Angelina have been friends for almost a decade now. They met in their high school years, now they have decided to pursue different paths for their college education. Joseph entered college under a program of business administration; Kairos pursued a similar course under the program of economics. Karina and Angelina who both shared undying passion specialized in two major art subjects. Karina studied arts and letters; while Angelina enrolled in a program of music. Angelo, the techno savvy of the group enrolled to be an information technology specialist someday. And lastly, Francis the most authoritative of them all enlisted in the police academy to become a member of the police force someday. All of them are happy in their pursued lives, but there are things that remain the same –their friendship and their enthusiasm to listen to music. It became a habit for them to meet up during weekends to catch up over dinner, share a couple of laughs and go back to their mishaps and fun times when they are still in high school. In one of their dinner at Kairos’ place, they chose to play a concert video of Alicia Keys; but then something happened to Angelina†¦ (against) Angelina: Kairos, this is a nice DVD where did you get it? I did not know that they have already released this one. (pro) Kairos: They already have that one in Danton’s record bar down the street, but it is pretty expensive. I did not bought it, Angelo got it, (joking) it is no secret†¦our friend has pretty cool tricks in front of a computer. (pro) Angelo: Hey man, stop bragging about it. I might end up downloading whole day for these guys. It is pretty boring man, if it’s not free, I won’t bother at all. (pro) Kairos: Hey Angelina, are you ok? Do you feel something wrong? Or are you just too mesmerized with the glories of downloading? (against) Angelina: You’re unbelievable†¦ (pro) Karina: Hey Kairos, I think you hit a wrong†¦very wrong button. (pro) Kairos: huh? (against) Angelina: You are unbelievable! You are to busy computing how much you can save you became a common thief. (pro) Kairos: Are you serious? What did I do? (against) Angelina: You have practically stolen something and yet you act as if nothing happened. You and Angelo you both favor convenience without its obligations. (pro) Kairos: I did not steal anything; do not put that on me. Angelo is the one who downloaded. But still, I cannot see your point why you are overacting. (against) Angelina: Ok, I will indulge you and downloading accomplice in the implications of what you have done, shall I get started? Downloading is stealing because- (Angelo interrupts). (pro) Angelo: It’s free, get a computer and link it to the internet. You will find there it’s free; you cannot steal something which is free. That’s the glory of it, free downloading it is FREE and logically it will be free even from your so- called obligations . (against) Angelina: That is not the point, the point is just like any other form of art Alicia Keys’ concert is the result of her hard work and even painstaking attempts to create something exemplary beautiful. You stole that from her by not buying the original copy of her concert and opting to download a mere duplicate of her work. (pro) Kairos: Last time I checked recording companies, reap off a lot from the original copies, not the artist. The competition between record labels is too superficial for ordinary citizens, just like me and Angelo to purchase the original copy. Original copies are too expensive; it is like a monopoly of record labels, prices do not compete . And with what I learned, the recording industry without competition is no longer viable as a form of market. (against) Joseph: Excuse me, but I think the likes of you and Angelo are the reason for the increase in the prices of original copies. Companies compensate for their losses from free downloads and other forms of piracies . Kairos, above everyone else in this room you should know that, your studying economics right? (pro) Kairos: Yes I am, what you are saying is profit making. I am standing on the notion of free. (against) Francis: Come one man, what you claim to be free as contested by Angelina is not free at all; I think, you are using the word in a wrong way. (against) Angelina: You cannot financially categorize the works of others for your benefit. It is true that the music industry is highly privatized. And it has a very good reason to do so; music is private in the sense that it is the fruit of the musician and singer. The prices are high simply because music is an innovation in its simplicity . The creation of an innovation is one thing, but guarding and protecting it from the likes of you and Angelo is another thing. (pro) Karina: I don’t know for music which is highly commercialized, I think individuals who want to access into a form of art should be allowed to do so as long as it is permitted by the artist. I doubt that a real artist would deny such privilege. (against) Angelina: Karina, you are an artist yourself or at least someone who is aspiring to be. How can you reach your dreams if your early first steps are being trampled by piracy such as that experienced by starting out musicians in free music downloading? (pro) Karina: Pirated works are usually that of already â€Å"made† stars, free downloading has minimal effects to starting musicians since their works are not there in the first place . Websites do not host unpopular music files. As a matter of fact, only 1% of websites have more than 50% of the general traffic in the internet . In short, starting bands are usually and probably exempted. (pro)Angelo: What Karina told is true in both statistics and even in logic. Angelina, some starting bands even welcome the idea of being pirated simply because it is a good venue to be established in the music industry which is dominated by bigger music labels . (against) Angelina: No matter what statistics you would use, it is unethical because it is stealing in the first place and will forever be stealing. (against) Francis: It is true that it is stealing but only through a different way such as the internet . That difference makes some individuals assume that they are doing nothing wrong, but actually they are. (pro)Kairos: Well, we can look at this issue through multi perspectives and that what makes it problematic. We can argue regarding this issue for a long time, but nonetheless we will never arrive at a common ground. (against) Angelina: So guys, since the topic can be debated indefinitely can we just leave the topic alone and continue to live according to our principles and promise to compromise in the presence of another contradicting principle? (against) Angelo: Hey, what friends are for? All agreed to give up on the debate and just enjoy the rest of the night with stories that would allow them to catch up with each other. Their circle of friendship grew stronger after such a healthy debate; all of them without exemption learned to compromise. Impact Statement: The issue of free downloading music through the internet can be debated on different point of views and starting points. Due to this nature, up to date the debate whether music should be a free enterprise at some levels is still questionable. Issues on it being ethical are not solely debatable in the light of being a free enterprise or a private intellectual property; it can also be debated on the perspectives of economics and profiteering. There are countries that allow free downloading of music such as China, so in terms of citizenship in relation to the issues on ethics behind free downloading of music the countries ruling are still the end of it all. No matter how long debates can be, it can only affect public opinion; nonetheless the law will still hold. After watching this group of friends argued on the topic. It can be said that the main question is wrong and prejudicial. â€Å"Is it ethical to STEAL music online? † should be replaced by â€Å"Is it ethical to DOWNLOAD music online? † Bibliography 123HelpMe. com.

The american holocaust essays

The american holocaust essays What Ever Happened to the Indians?-A Look into the American Holocaust For years and years students across the world have studied and memorized endless gory facts about massive genocides such as the Jewish Holocaust, the World War Two atomic bombs, and the religious Crusades. These were extremely significant events during the history of the world because they changed the lives of so many people. Millions of people were killed during these three events simply because of their religion or the color of their skin. All of these genocides were unique for one reason or another including the numbers of people killed or the time period in which it took place (Stannard 151). Several books, including school textbooks, often go into great detail describing these bloody events. However, as horrible as these extensive murders were, there was another massive genocide that occurred right in our own country that is barely acknowledged when compared with these other three, especially the Jewish Holocaust. The extermination of almost all Native American Indians was easily one of the most horrific genocides in history, totaling nearly 100,000,000 deaths (Stannard 151). Yet this particular genocide is barely given any attention. In his book American Holocaust, David Stannard questions why we, the world as a whole, dont seem to care about the terrible things that the Europeans did to the Native American Indians. Also, why, when more Indians were killed, is there more emphasis on the Jewish Holocaust and other extreme events? And finally, why did the Europeans find it necessary to exterminate virtually every American Indian? He seeks to answer these questions and more through examples of torture techniques, European attacks on Indians, and other evidence that he researched. Stannard comments on how there is a traditional Eurocentric bias that lumps undifferentiated masses of Africans into one single categ...

Finance - Budgeting Paper Essay Example | Topics and Well Written Essays - 1500 words

Finance - Budgeting Paper - Essay Example Thus, an external way is proposed to finance the budget deficit financed by collection of taxes. The budget deficit is expected to accrue from the demand of residents of Kelsey state for more security operations around the City of Kelsey to curb the rising insecurity levels in recent times (Premchad 1989). Also, the recent federal government policy to cut down state government financial allocations will reduce the amount of funds needed to satisfy all the state priorities. The money sourced from the new source is to be fully allocated to the security department within the city council of Kelsey. This will be essential for more local policing surveillance around the city and its environs. Also, in order to fill the deficit created, the budget committee has proposed a number of fund reductions in some state operations in the coming year. The fund that would have being allocated to the proposed departments to face fund reduction, is under the proposal of the committee to be channeled to wards hiring more police officers, increased surveillance and building of new prisons in the coming fiscal year (Adams and Williams 2010). 2.0 June 2012/ June 2013 Budget Plan; The budgetary plan for this fiscal year as illustrated below is an outline of the general framework of budget goals and objectives that needs to be met on state operations, servicing debts, capital expenditure, state reserves and financial reporting (Lee, Joyce and Wayne 2008). The budget plan proposal for this fiscal year provides standards that can allow current budget performance to be measured against in the future budget proposals that may face similar or unique problems the city of Kelsey is currently facing. The city is facing a security threat from a rate of crime it has never faced before. The rate of crime has been noted as a big threat towards the social, political and economical development to the resident of Kelsey city. This has called for an immediate action against the crimes to prevent the ci ty from the posing disaster. I, as the budget manager of Kelsey state fiscal budget together with the budget committee have come up with a budget proposal that tries to reflect the cure of the problem (Riley and Colby 1991). The annual budget, under the fiscal policy of Kelsey state as per the state statue is adopted by November and completed in June. The budget is required under the state fiscal policy also, to be debated for six months prior to its adoption. Under the current environment of an escalating crime level, I have proposed that the fiscal cycle to be amended in order for the security concerned departments to access funds to curb the crimes. The budget proposal should be debated in the month of May by the mayor and the council and adopted in June. This has been noted that it will be against the fiscal policy of Kelsey state, but it will be necessary in the fight against the crime level before it hits uncontrollable level. 2.1 Operating budget plan; The current revenues wi ll not be enough to finance current operating expenditures. This is as a result of the proposal to increase budget allocation towards policing operations. The estimated general fund for the state operating revenue is expected to be $ 40 millions and the expenditures under operations are expected to be $ 50 millions. The ratio of the two estimates stands at 1: 1.25 which means the estimated

Herbicide X Case Study Example | Topics and Well Written Essays - 250 words

Herbicide X - Case Study Example The results ultimately proved that the level of concentration is enough to cause cancer to the rats. The same concentration of Herbicide X is being used by farmers to control the weed as this is highly effective. In view of this, Herbicide X poses extreme threat to the humans as it is used in the same dosages as found to have affecting rats. Herbicide X is sprayed in the farms twice, once in the spring and the second time in fall. This means that farmers are exposed to the Herbicide X twice in a year that increases the health risk associated with this pesticide. It is quite scientific to assess the risk of any hazardous chemical first on animals such as monkeys, rats, cows. It is certified and confirmed by several peer-reviewed studies that Herbicide X is toxic in the given dosages and cause deadly disease like cancer. It is quite appropriate to conclude that it indeed poses a threat to the human life too, especially when humans are exposed twice in a year with the same level of concentration that affected rats. Moreover, it has also been found that Herbicide X remains in the environment for at least 3 months before it disintegrates into harmless substances; it is slow in biodegradation and not eco
