Acid Rain 8 :: essays research papers

Acid Rain is a type of air pollution, which is formed when oxides of sulfur and nitrogen combine with atmospheric moisture to yield sulfuric and nitric acids, which may then be carried long distances from a source before they are deposited by rain. This pollution may also take the form of snow, fog, or a dry form of precipitation. Acid rain is currently a subject of great controversy because of widespread environmental damage, for which it has been blamed, including eroding structures, injuring crops and forests, and threatening or depleting life in freshwater lakes.   Ã‚  Ã‚  Ã‚  Ã‚  The problem of acid rain originated during the Industrial Revolution, and has been growing ever since. The severity of its effects has long been recognized in local settings, exemplified by the spells of acid smog in heavily industrialized areas. The widespread destructiveness of acid rain, however, has become evident only in recent decades. One large area that has been studied extensively is northern Europe. In 1984, for example, environmental reports indicated that almost half the trees in Germany’s Black Forest had been damaged by acid rain. This form of pollution has also particularly affected the northeastern United States and eastern Canada.   Ã‚  Ã‚  Ã‚  Ã‚   Industrial emissions have been blamed as the major cause of acid rain. Because the chemical reactions involved in the production of acid rain in the atmosphere are complex and as yet little understood, industries have tended to challenge such assessments and to stress the need for further studies; and because of the cost of pollution reduction, governments have tended to support this attitude. Studies released by the U.S. government in the early 1980s, however, strongly implicated industries as the main source of acid rain in the eastern United States and Canada. In 1988, as part of the United Nations-sponsored long-range Transboundary Air Pollution Agreement, the United States and 24 other nations ratified a protocol freezing the rate of nitrogen oxide emissions at 1987 levels. The 1990 amendments to the Clean Air Act of 1967 put in place regulations to reduce the release of sulfur dioxide from power plants to 10 million tons per year by January 1, 2000.

The Failure and Rebirth of Burmese Nationalism Essay -- International

All people in the world strive to find a sense of belonging. This sense is coupled with ethnic identities, cultural customs, and social implications. The groups that inhabit the corner of the world, now known as Myanmar, have had great struggles and upheavals through the last century. They have been stricken with World War, independence struggles, as well as military dictatorship. The Burmese groups have tried with diligence to establish their own states, but in the end all has fallen upon them and their tale is one of grief and sadness. The failure of Burmese nationalist movement is through the conflicting interests of the world, the clashes between Burmese ideology, and the differences of ethnic acceptance. However badly the movement failed, a new movement has taken form and is a blossoming root of hope for the millions of Burmese living in poverty today. The area in Southeast Asia that contains Burma today has been a place of human life for millennium. Leaders came and went, and the usual cycle of empires, kings, and regimes passed over the people of Burma. The scene of nationalistic fervor, however, starts after the takeover of Burma by the British through the entirety of the nineteenth century (Badertscher). Like always, â€Å"the British began to permeate the ancient Burmese culture with foreign elements†, thus starting the colonial period of Burma’s history and of struggles to resist such control (â€Å"Burma†). Using a divide and conquer strategy, British command authorized minorities like the Karen group of Burmese to be â€Å"in the military and in local rural administrations† (â€Å"Burma†). This way they built resentment that is still apparent in many cases today. The nationalist movements present globally in the nineteenth and twent... ...artin, Patricia. "Aung San Suu Kyi."

frost Essay -- essays research papers

The Road Not Taken In line one, Frost introduces the elements of his primary metaphor, the diverging roads. Lines two to three expresses the speaker's disappointment with his human limitations; he must make a choice. The choice is not easy, since "long I stood" before coming to a decision. Lines four and five examine the path as best the narrator can. However his vision is limited because the path bends and is covered over. These lines indicate that although the speaker would like to acquire more information, he is prevented from doing so because of the nature of his environment. In the following three lines, lines six through eight, the speaker indicates that the second path is a more attractive choice because it appears as though nobody has ventured down it recently. However, he remains ambivalent, since the traveled path is "just as fair.?Although the poet breaks for a new stanza after line 10, the comparison of the paths continues in lines nine through twelve. Here, the speaker state s that the paths are "really about the same." Neither path has been traveled lately. Although he's searching for a clear logical reason to choose a single path, not one presents itself. In lines thirteen through fifteen, the speaker makes his decision. He tries to rationalize that he will be able to traverse both paths one day. However, he is quick to dismiss his hopes. Ending line thirteen, the exclamation point conveys excitement, but that excitement is quickly undercut by the admission contained in the following lines. In the final four lines, the only stanza beginning with a new sentence, the tone clearly shifts. The speaker imagines himself in the future, discussing his life. What he suggests, here, though, appears to contradict what he has said earlier. At the end of the poem, in the future, he will claim that the paths were different from each other and that he, courageous, did not choose the conventional one. Frost's quarrel with the world is apparent in this poem. The speaker of this poem, presumable Frost himself, is forced to make a decision. Literally, he must choose a path in the woods. However, Frost's paths in the woods metaphorically describe the decisions that one must make in life. Frost is perturbed with the world because, like the speaker, he has to choose between two divergent paths. Each path appears to be suitable, yet, Fro... ... done something or spoken a word that indicates who he really is, there is no turning back, in cannot be undone. Once again at the end of the poem regret hangs over the traveler. He realizes that at the end of his life, somewhere ages and ages hence? he will have the regrets about having never gone back and traveling the road he did not take. Yet, he remains proud of his decision and recognizes that it was this path that he chose which helped him live the life he did. â€Å"I took the road less traveled by and that has made all the difference? To this man, the most important thing was that he did not have to follow the crowd and could stand independent and travel down the road he really wanted to. If he had not, he would not be the same man he is now. There are many equally valid meanings to this poem and Robert Frost may have intended this. He may have been trying to achieve a universal meaning. In other words, there is no real moral to the poem. There is simply a narrator who makes a decision in his life that changed the direction of his life. It allows all readers from all different experiences to relate to the poem and encourages each to peruse his own dreams and individuality. frost Essay -- essays research papers The Road Not Taken In line one, Frost introduces the elements of his primary metaphor, the diverging roads.

Agribusiness – Essay

The word agriculture indicate plowing a field, planting seed, harvesting a crop, milking cows, or feeding livestock. Until recently, this was a fairly accurate picture. But to days’ agriculture is radically different. Agriculture has evolved in to agribusiness and has become a vast and complex system that reaches for beyond the farm to include all those who are involved in bringing food and fiber to consumers. Agribusiness include not only those that farm the land but also the people and firms that provide the inputs (for ex. Seed, chemicals, credit etc. ), process the output (for ex. Milk, grain, meat etc. , manufacture the food products (for ex. icc cream, bread, breakfast cereals etc. ), and transport and sell the food products to consumers (for ex. restaurants, supermarkets). Agribusiness system has undergone a rapid transformation as new industries have evolve and traditional farming operations have grown larger and more specialized. The transformation did not happen over night, but came slowly as a response to a variety of forces. Knowing something about how agribusiness came about makes it easier to understand how this system operates today and how it is likely to change in the future. Initially agriculture being the major venture it was easy to become a farmer, but productivity was low. Average farmer produced enough food to feed just four people. As a consequence most farmers were nearly totally self-sufficient. They produced most of the inputs they needed for production, such as seed, draft animals, feed and simple farm equipment. Farm families processed the commodities they grew to make their own food and clothing. They consumed or used just about everything they produced. The small amount of output not consumed on the farm was sold for cash. These items were used to feed and cloth the minor portion of the country’s population that lived in villages and cities. A few agricultural products made their way into the export market and were sold to buyers is other countries. Farmers found it increasingly profitable to concentrate on production and began to purchase inputs they formerly made themselves. This trend enabled others to build business that focused on meeting the need for inputs used in production agriculture such as seed, fencing, machinery and so on. These farms involved into the industries that make up the â€Å"agricultural inputs sector†. Input farms are major part of agribusiness and produce variety of technologically based products that account for approximately 75 per cent of all the inputs used in production agriculture. At the same time the agriculture input sector was evolving, a similar evaluation was taking place a commodity processing and food manufacturing moved off the farm. The form of most commodities (wheat, rice, milk, livestock and so on) must be changed to make them more useful and convenient for consumers. For ex. consumers would rather buy flour than grind the wheat themselves before backing a cake. They are willing to pay extra for the convenience of buying the processed commodity (flour) instead of the raw agriculture commodity (wheat). During the same period technological advance were being made in food preservation method. Up until this time the perishable nature of most agriculture commodities meant that they were available only at harvest. Advance in food processing have made it possible to get those commodities all throughout the year. Today even most farm families use purchased food and fiber products rather than doing the processing themselves. The farms that meet the consumers demand for greater processing and convenience also constitute a major part of agribusiness and are referred to as the processing manufacturing sector. It is apparent that the definition of agriculture had to be expanded to include more than production. Farmers rely on the input industries to provide the products and service they need to produce agricultural commodities. They also rely on commodity processors, food manufactures, and ultimately food distributors and retailers to purchase their raw agricultural commodities and to process and deliver them to the consumer for final sale. The result is the food and fiber system. The food and fiber system is increasingly being referred to as â€Å"agribusiness†. The term agribusiness was first introduced by Davis and Goldberg in 1957. it represents three part system made up of (1) the agricultural input sector (2) the production sector and (3) the processing-manufacturing sector. The capture the full meaning of the term â€Å"agribusiness† it is important to visualizes these there sectors as interrelated parts of a system in which the success of each part depends heavily on the proper functioning of the other two.
