Environmental economics Essay Example for Free

Environmental economics Essay It is a familiar characteristic of city life; it is a type of large scale outdoor pollution. It consists of fog grossly contaminated by the product of the inefficient combustion of coal. Chemical reaction between pollutants derived from different sources primarily automobile exhaust and industrial emissions. For each city that exact causes of pollution may be different, depending on the geographical location, temperature, wind and weather factors, smog in its acute form occurs especially during the warm months of the year. Notable, air pollution disaster of this kind was recorded in December 1952 where London smog lasted in the acute stage for five days and overall for ten days. Casualties were among cattle and opera performance had to be stopped after the audience had no vision of the stage. More seriously though, it was estimated to have been directly responsible for an additional four thousand deaths. Specify the externalities/factors that have made this problem and the extent of the externalities involved, the impact and recent trends. In pure market economy resource allocation is the result of the decisions of consumers (households) and producers (firms) who seek to maximize the difference between benefit and incurred costs i. e. private benefit and private cost. But in the weakness of the market economy is that it may fail to take account of any additional benefit or cost which spill over from the original decisions. The cost or benefits additional to those which are the immediate concerns of the parties to a transaction are the spill-overs or externalities, they are not provided for directly in the market place. Due to activities of individuals or firms human based or naturally pollution occurs as a result of emitting too much of a substance to the environment so as to have harmful effects. Every time we breathe, we risk inhaling dangerous chemicals present in the atmosphere. These dangerous chemicals can be either in form of gases or particles and have diverse and numerous effects on human beings and the natural ecosystems. Because it is located in the atmosphere, air pollution is able to travel easily therefore making it a global problem and to a subject of cooperation and conflict. Emission of nitrogen oxide, carbon monoxide, sulphur dioxide, lead, suspended particulates and organic compounds that can evaporate and enter the atmosphere. Air pollution caused naturally includes forest fires, volcanic eruptions, wind erosion, pollen dispersal, evaporation of organic compounds and natural radio activity. This does not occur in abundance in particular locations. Most pollution is as a result of human activity. The biggest causes are the operation of fossil fuel: burning power plants and automobiles that combust fuel. These few factors are responsible for up to 90% of all air pollution in the United States alone. Other cities like Japan, China, Mexico and San Paulo have some of the most deadly pollution emission levels in the world. The world we are in is driven by fossil fuels, cars and other forms of transportation i. e. tracks, trains, aeroplanes e. t. c. run primarily on gasoline derived from oil. We can therefore say that some of the pollution issues that we face currently are directly related to the energy choice we have. Cooking, heating, lighting, e. . c. for homes, work places, industries using oil, coal and natural gas making us prone to pollution. Solutions to this problem begin with the logic of cost. This is where issues of renewable energy alternatives are suggested but corresponding arguments of greater energy efficiency and reliance on renewable energy is also advocated for. Some notable air pollution disasters are for example: the most publicized issues of second hand smoking. The smokers not only harm themselves but also others close by when they breathe this smoke. Industrial emissions did contribute to respiratory symptoms for several individuals and sixty deaths in Meuse area of Belgium in December 1930. In Danara, Pennsylvania, October 1948, twenty people died as a result of smog. This is a recurring problem that has seen world population mortality rate go up, low life expectancy e. t. c, this is due to diseases present in modern society and were not present 100 years go. Define using examples how policies to reduce this problem could be measured. Benefit management Policies set out to restrict smoking are important in attaining a healthy environment and individual. Policies to regulate smoking are in effect in some locations, but personal exposure should be motivated and limited wherever possible. However a combination of scientist, legislators, business leaders and individuals is a prerequisite for adherence and advocacy with a view to achieving a better environment. In this case therefore second hand smokers are protected especially in public places, this has therefore resulted to a decline in lung cancer, respiratory cases which would have cost the government and the unsuspecting persons a lot of money for treatment. On realizing the catastrophic effect of pollution and the environmental and personal costs associated with it, monitoring the air and environment campaign lead to: (i) Education in schools and universities where students begin at a very young age learning about the effects of pollution. They are taught and trained on management and conservation which carries in handy in the proceeding years of their life. (ii) Scientific groups have also been formulated as a result of government policies. These aim to study the environment with a view of coming up with solutions of encroaching problems and finding lasting and workable solutions (iii) legislative bodes have also contributed enormously by writing down laws that control emission. In this case therefore persons found violating the set laws is liable for prosecution. This makes industries oblige to avoid pollution and consequently revert to better and safer methods of production. (iv) Policies have also enabled the setting up of regulatory agencies e. g. united nations, the atmosphere management program to carry out environmental projects. They are bale to monitor, advocate and control the environment. These and much more are examples on policy formulated for better management and monitoring of the environment. As a result therefore emission of waste to minimized, controlled and checked. Dumping, waste disposal and waste management is carried out in a better way and thus reducing pollution levels. We also see that health cases and deaths are minimized, the government and individuals end up spending less for treatment in pollution related illnesses. The scenarios and beauty of landscapes, plants, etc is also retained. Measuring the cost of reducing the problem In conducting environmental sound economic analysis, we are required to determine the environmental and natural resource impact of the project or policy in question. In this case therefore it is the smog effect. It should also handle biological and social effects. One needs to measure the impact to determine the cost of solving it and this relies on the experts such as engineers, ecologists, agronomists, etc. We also put into consideration valuing the physical impact and relationship. Environmental impact can result in a miserable change in environmental quality. Estimating cost is generally easier than estimating benefits but it is not easy. One major problem derived from the fact that benefit cost analysis is forward looking and thus requires an estimate of what a particular strategy will cost which is more difficult than tracking down what an existing strategy does cost. Another fundamental problem disposed by collecting cost information when the availability of the information is controlled by a firm having an interest in the outcome.

Impact Of Climate Change On Insurance Companies Commerce Essay

Impact Of Climate Change On Insurance Companies Commerce Essay Change in climate is emerging up as a new type of issue in the security aspect because of the way it affects both the life and the well-being of humans in a highly interconnected and fragile world. (Evans, 1994, 107-128) Changing climate is becoming a threat to the basic welfare and survival needs of humans across the globe, including the production of food, health, access to water and the utilization of land. Environmental deprivation rising from different kinds of economical activities of humans has increased the intensity and frequency of natural disasters throughout the world. Around the world, there has always been natural development in the weather and climate events. In fact, the insurers have become experts in modelling the disastrous risks which has now become an incorporated instrument in the insurance industry. This has helped a number of businesses to digest the losses from unexpected natural disasters without important defaults. This has now led to the fact that insurance companies have become more refined in analyzing, managing and understanding their recent risks because of their natural disasters around the world. Many of the companies in United Kingdom are observed to be improving in managing and assessing their ways of dealing with the future trends and risks of the industry. As a number of UK insurance companies have started to note it, depending on their previous weather conditions and patterns for planning out strategies for future. For this, they must identify the probability of losses and gains related to weather conditions. The impact of climate change is on a very wide range from increased amount of hurricanes, fires and floods to health and life getting affected by changing patterns of hot and cold weather. (Evans, 1994, 107-128) Physical impacts effect on insurers: Companies of insurance and reinsurance are likely to face the strong impact of the changes in climate more than other parts of the financial businesses. There are a number of examples where it is seen that that how extremely weather condition can affect the insurance companies, the government and the sectors at backstops. Whilst there are examples of how the weather changes are affecting the insurance industry because of the flexibility of the insurance sector, in other ways it is quite well positioned in adapting the changes in weather events and patterns. (David, 2007, 28-38) Threat of climate change for insurance industry: The main threat that is facing the insurance industry is climate change. This threat affects both property and casualty insurance that the insurance people. Another concern: the two sectors will have to adapt to demographic change that is looming. This emerges from a study by Ernst Young, in collaboration with Oxford Analytica. Ernst Young has compiled a top ten list of threats that will confront insurers after interviewing twenty industry leaders worldwide. According to Ernst Young, climate change tops the list because global warming is changing the climate and increases the likelihood of claims arising from floods, hurricanes and other natural phenomena. Im not sure the industry is poised to cope with climate change, warned Tom Kornya, a partner at Ernst Young, in an interview with Insurance Journal. Five years ago, this risk was not even on the list. Mr. Kornya adds that not only the sector of damage insurance that will be affected by climate change, life insurance should also deal with it sooner or later. Damage will come to insurance when climate change will result in wind storms and floods. In life insurance, the consequences will be gradual. With temperatures that may change, life insurers will face new problems in health and mortality. So there could be different types of losses. The underwriting of these products is booming and no one has yet measured that cause climate change. The success of the industry will go through the development of innovative products, which will face great uncertainty, such as typing speed and severity of climate change, he said. The second risk that the industry faces is the demographic change with the arrival of the baby boomers retire, resulting in new needs. Insurers would be under great pressure, they will need to replace governments. (Rober, 2010, 34-33) In addition to the pressure generated by this new role, insurers will also deal than their competitors. Banks, mutual fund companies and all financial institutions will struggle to get the same dollar. There is a risk there too. Insurance companies must remain innovative with their products to keep the advantage, says Kornya. (Rober, 2010, 34-33) The environment in which insurers and practice is constantly changing quickly, said Tom Kornya. We find that consumers are looking for simple, low cost products and others who want more complex products that are also more expensive. A company that will not have a multichannel access could fall into the background if it does not use Internet, media and telephone. The last two threats on the list of the top ten risks of Ernst Young are the legal uncertainties and the possibility of geopolitical or macroeconomic disturbances. In the first case, accountability and reform in terms of crime could lead to financial losses. For the second, the firm says that the threat of a severe financial crisis due to derivatives and hedge funds could be damaging to the industry. Opportunities for insurance: Climate change presents risks but also opportunities. The possible opportunities created by the effects of a changing climate may require nurturing through the dedication of attention and resources. Too often, news coverage portrays climate change as a doom-and-gloom story of impending disaster. Certainly, many of the possible impacts of climate change are likely to negatively affect us, and we must address them, but we should not ignore the possible opportunities that a changing climate could create in part by proactively adapting to them. Some economic sectors and businesses may do better because of the effects of climate change, and they should seek to identify those new economic opportunities and invest in pursuing them. Turning back to the example the reduced reliance on winter roads due to warmer average temperatures disrupts supply chains and increases costs for the mining companies operating in the region. (David, 2007, 28-38). It is a risk for insurers, but also a great opportunity, says Tom Kornya. There will be a great demand for pension products. Baby boomers look for low-cost products that generate revenue. By cons, debate the role of government in the pension is not very advanced. Insurers will be required to take this place and this is a new risk to which they are unaccustomed. Financing and advisory Companies in carbon-intensive sectors are already seeking finance to help them decrease greenhouse gas emissions. In the public sphere, large sums of capital will be needed in the coming decades to develop, modify and renew key energy, transportation and flood defense infrastructure across the world. Climate change may appear to be a slow burn issue for the financial sector, but companies would be wise to give it significant attention, as much for the emerging upsides of changing demand as for protecting themselves against the erosion of value in the long term. Hedging and trading The demand from the industry is increasing for a number of risk transfer instruments in order to protect the companies against the increase in the prices of energy, the changing patterns of weather and the probable failure of current newly introduced technologies. The occurrence of carbon among the commodities that are tradable has grown higher to complex products that are starting to pull a large number of financial organizations and allow some further violation and exploitation of the products. Consumer revenues The awareness spread about the green issues encourages growth in socially responsible investments by the consumers and organizations alike. Even though, the market for mortgages, insurance and loans that give reward to low carbon behaviour is right now less, it may increase quickly. Similarly, the increased awareness of windstorms and floods has started to increase the desire of customers who are at risk for the property and casualty insurance. Implications: There are a number of activities that the insurance industry can do in order to improve their understanding of the impact and affects of change in climate, help the society and government to understand in a better way and prepare for the risks involved in the development in fire-prone or coastal areas and make items that could protect their clients from the damage induced by the climatic change. Following are some of the implications in order to reduce the negative impact of the climate change on the insurance industry: (Evans, 1994, 107-128) Most of the climatic scientists agree that the weather conditions in future are most likely to differ that the previous weather conditions. Thus, it will be sensible for the insurers to understand in a better way, what will be the future if the predictions of the scientists are true. Risk models can be developed on the basis of these predictions with the help of expertise. We can also put more potential for the research and studies as they will provide more knowledge and analytical capacity. It will also help in enabling the insurance companies to find the hidden markets and new opportunities for their products along with the risk management and educating consumers. (Rober, 2010, 34-33) Work with the scientists in order to raise the economic relevancy and accurateness for the climatic change modeling. Disclose and acknowledge the risks of climatic change in annual security filings and by other business communications. Should take a practical approach in order to influence the planning and development of land use, in fraction as most of the expected rise in the losses are stemming out from the disastrous events that could be prevented by good spatial planning. There are a number of steps that could be taken: 1) keep the valuable property out of the risk regions and 2) grant both the economic and environmental benefits.

Global Industrial Issues: Special Economic Zones in India

Global Industrial Issues: Special Economic Zones in India India was one of the first in Asia to recognize the effectiveness of the Export Processing Zone (EPZ). The chief drawbacks of EPZ were multiplicity of controls and clearance, absence of world class infrastructure and instable fiscal regime. The Special Economic Zone Policy (SEZs) was announced in 2000 and it tried to look into the drawbacks of the EPZ policy. SEZs are engine for economic growth supported by quality infrastructure, attractive fiscal package and minimum possible regulations. The main objectives of the policy are: Generation of additional economic activity Promotion of exports of goods and services Promotion of investment from domestic and foreign sources Creation of employment opportunities Development of infrastructure facilities. The SEZ rules provide for Simplified procedures for development, operation and maintenance of the SEZs and for setting up units and conducting business in SEZs Single window clearance for setting up an SEZ Single window clearance for setting up a unit in a SEZ Single window clearance on matters relating to central as well as state Governments Simplified compliance procedures and documentation with an emphasis on self certification. Incentives and Facilities Offered to the SEZs: Duty free import/domestic procurement of goods development, operation and maintenance of SEZ units. 100% income tax exemption an export income for SEZ units for the first 5 years, 50% for the next 5 years thereafter, and 50% of the ploughed back export profit for the next five years. Exemption from minimum alternate tax, central sales tax and service tax. External commercial ______ by SEZ units up to US $ 500 million in a year without any maturity restriction through recognised banning channels. Single window clearance for central and state level approvals. Major Incentives and Facilities available to SEZ developers include: Exemption from customs/excise duties for development of SEZs for authorised operations approved by Board of Approval (BOA) Income tax exemption on export income for a block of 10 years in 15 years Exemption from minimum alternate tax, dividend distributors tax, Central Sales Tax and Service Tax. The SEZs trigger a large flow of foreign and domestic investment, resource utilisation and generate additional economic activity. Newly Industrialising Countries Newly Industrialising Countries (NICs) are those industries whose economics have not yet reached first world status but are more developed than their developing counter parts. The other characteristics of NIC’s is rapid economic growth (usually export oriented), optimal resource utilisation, rapid pace of industrialisation and a pool of labourers. Hongkong, South Korea, Singapore, Taiwan rose to global prominence with rapid industrial growth since 1960’s. This was possible with optimal resource utilisation. These countries can be considered as first generation of NIC’s. Organisation of or Economic Cooperation and Development (OECD) and __ have helped in the development of NIC’s. NIC’s usually benefit from comparatively low labour costs and larger market. Currently the following countries are considered as NIC’s China, India, Malaysia, Philippines, Thailand (Asia) South Africa (Africa); Mexico (North America) Brazil (South America) and Turkey (Europe). Organisation for Economic Cooperation and Development The organisation for Economic Cooperation and Development (DECD) is an international organisation of thirty countries that accept the principles of representative democracy and free market economy. It originated in 1948 as Organisation for European Economic Cooperation (OEEC) and was reformed into organisation for Economic Cooperation and Development in 1961. The OECD covers all economic, environmental and social issues. It identifies common problems and good practice and coordinates domestic and international policies. The organisation collects data, monitors trends and forecasts economic developments. It also analysis the patterns in trade, environment, agriculture, technology, taxation and other areas the secretariat of OCED looks into entrepreneurship, fax policy, employment, labour, trade, agriculture, financial and enterprise affairs etc. The organisation further looks into the development of nuclear and energy resources. Most of the countries of Europe are part of it – Austria, Belgium, Denmark, France, United Kingdom etc. Besides it Japan and South Korea (Asia) and united states of America and Canada are also a member of OCED. G8: The Group of Eight (G8) is an international forum for the governments of Canada, France, Germany, Italy, Japan, Russia, United Kingdom and United states. The concept of the forum for the world industrialised democracies emerged after the 1973 oil crisis and subsequent global recession. The G8 countries discuss the topics of labour, economic and social development, energy, environment, trade etc. The forum discusses the global issues in an informal manner. New Post W W II trends in Industrial Resource The post world II period observed many changes in the utilisation of resources for industrial development. Some of the following trends were observed: De industrialisation and restructuration as a result of changing industrial policies of linearization and globalisation. The phase of deindustrialisation and restructuration was followed by the renewed programmes and changes in location and structure of plants was observed. The plants were reallocated and many multi functional companies became more functional. The structure of industries shifted from fordism to Neo-fordism post fordism. The lower order industrial regions termed as dusters and complexes came into existence. These phenomena are the phase of rejuvenations in manufacturing systems. These are a result of newer innovations and technologies. Thus, the resource are utilised in a more appropriate manner. The improvements in means of transport and communication has encouraged the process of industrialisation. Further, the rational and planned formulative policy for manufacturing give rise to inter-national companies (MNC’s). The location and reallocation of resources and industries have created decongestion of industries and thus lower order clusters and complexes have come up in existence. These are well equipped with newer technologies. OCED’s , NIC’s, G8, BRICS, SEZ’s have accelerated the process of resource allocation. Thus, the combination of spatial dispersal and global integration has created new centres as Highly concentred command points in the organisation of the world economy Key locations for finance and for specialised service firms Sites of production, including the production of innovation in these leading industries and Markets for the products and innovations produced. High Tech Manufacturing Development Foci: A number of specialised high technology centres (also termed as footloose industries) have developed in the world. These units are largely located nearer to universities and research institutions. Silicon Valley in California near Stanford Unweisily and ‘Boston Route 128’ near Massachusetts Institute of Technology (MIT) are one of the centres which have developed Many IT industries like IBM are engaged in research around here. Subsequently, the research and industry partnership hubs have developed all over the world-many countries of Europe, Japan, South Korea, Mexico, India etc. Foot loose industries are highly flexible and are largely dependent on highly literate young entrepreneurs, with little cash and space. The high tech industries are functionally discrete by nature and look into design, development and fabrication. The re-industrialisation restructures the national and economic landscape and there is a development of three lower order industrial developments. Industrial districts at a comparatively higher spatio functional level Flexible specialisation at international level _____ at local level. Utilisation of resources underwent a transformation with a change in the approach of establishment of industries and subsequently utilisation of resources. Neo-fordism evolved for the continently of fordist, labour process but post fordism stressed complete break. Global Industrialisation Related Problems: Globally, differential development of industries is observed. Thus, differences in utilisation is also observed imbalances are visible in developing and developed regions of the world. Different issues are observed in developed and developing countries. Some industrial products whose demands have been increasing since Industrial Revolution might now experience a decrease in demand. The growth rates are either stagnant or have decreased in the already developed regions which these rates have accelerated in the developing countries. Since mid 1970’s the demand for many consumer goods have established in Developed countries because of the changes observed in population growth rate has become negligible. Besides, world recession, average personnel disposable income, changing technology, increased durability of the products are some of the factors responsible for the decrease in demands for industrial products in mid 1990’s. Although, the demand for goods declined in 1990’s but on the other hand, worldwide capacity has increased because of the following factors: The diffusion of industrial revolution and basic level of technology for commonly demanded items such as textiles, iron and steel, automobile, etc from developed to the less developed world. Increased output capacity by developed nations as a resuet of technological inventions and innovations and change in the structure of resource utilisation. The shifts of hubs of industries. The early concentration (followed by Industrial Revolution) was in UK in 19th century followed by USA, USSR; Germany and Japan. China, Mexico and Indonesia followed the above countries and the industrial production increased. In the 21st century many Asian countries (Newly Industrialising countries), South Africa (BRICS), Taiwan, Singapore and. Industrialisation plays an important role in national economy: Through industrialisation the country sustains itself and provides indigenous goods and products. Thus also helps in improving the economy of the nation. The process of industrialisation helps in promoting the development of essential infrastructure of a region. Thus, the process of industrialisation helps in developing the various pockets of the country. As the process of industrialisation proceeds various under-developed pockets also are benefitted as the diversification of industrialisation becomes more and more strong. The employment opportunities are generated. Thus, helps in improving the economy of the country. The resource exploration is done as per the needs and over exploitation can be avoided. On the other hand, industries can be developed in the resource endowed regions. Industrial Problems in Developed Countries: The largest challenge which the developed countries face is of change in structure of production – from fordism to neo fordism and post fordism, enhanced cost of labour, decline in the market with new market areas developing and procurement of resources. Earlier the industrialised grants of the world relied on international market for their products as well as they procured the resources globally 20th century witnessed the development of industries in many other parts of the world. The competition of markets has led to the grouping of countries. Such as European Common Market (ECM) Association of South East Asian Nations (ASEAN), North American Free Trade Association (NAFTA), Asia Pacific Economic Cooperation (APEC) Etc. These grouping helped in reducing trade barriers and the hubs of industrial regions are adversely affected. The countries which industrialised early, immediately in the post industrial revolution era because of the advancement in innovations and technology procured the raw material from the countries which were devoid of it from late 19th century and beginning of 20th century these countries started developing industries in their own parts. Thus, the already existing industrial hubs suffered from the availability of resources. The early industrialised countries suffered a setback of accelerating cost of labour. This was largely because of the low population availability. This promoted the change in structure of industries. Multinational companies came in instead of integrated industries. The multinational corporations helped in deindustrialisation and reindustrialisation. This helped in the development of new regions and few aheady industrialisation regions suffered a setback. Industrial Problems in Developing Countries: The problems of the developing are largely related to the availability of capital, latest technology, adequate infrastructure and proper management skills. These countries have entered the production late and are still in the infancy stage. Largely the developing countries are in there infancy stage and thus are facing problems of technological advancement and Automations and application of upgraded technology is essential for the increase in the production. The developing countries are not well equipped with trained managers, professionals and other supporting staff. This restricts the optimum utilisation of resources. Lack of basic infrastructure and amenities is another major constraint of the developing countries. Many developing countries are accelerating the process of industrialisation and ignoring the proper controls towards environmental protection which can harm human ecology. Industrial Problems in under developed Countries: Capital scarcity, poor labour asset, lack of latest technology and automation political instability economic recession and under developed infrastructure are some of the problems faced by under developed countries.

Corrosion and rubbing alcohol vs. corrosion and hydrogen peroxide â€Å"Are brass, lead, iron, and aluminum more likely to corrode in solutions of rubbing alcohol or hydrogen peroxide?† a. Definition-corrosion, rust, oxidation Corrosion is the atmospheric oxidation of metals. Rusting is essentially a process of oxidation in which iron combines with water and oxygen to form rust. Rust is the reddish-brown crust that forms on the surface of iron. Rust, a chemical compound, is a hydrated ferric oxide Fe2O3 ·nH2O, where n is usually 11/2. The chemical mechanism of rusting is not fully known, but is thought to involve oxidation of metallic iron to ferrous ion, (Fe++) and reaction of the ferrous ion with oxygen and water to form rust. This reaction is catalyzed by water, acids, and metals (e.g., copper and tin) below iron in the electromotive series. Because iron is so widely used, e.g., in building construction and in tools, its protection against rusting is important. Although metals (e.g., aluminum, chromium, and zinc) above iron in the electromotive series corrode more readily than iron, their oxides form a tenuous coating that protects the metal from further attack. Rust is brittle and flakes off the surface of the iron, continually exposing a fresh surf ace. Rusting can be prevented by excluding air and water from the iron surface, e.g., by painting, oiling, or greasing, or by plating the iron with a protective coating of another metal. Metals used for plating include chromium, nickel, tin, and zinc. Zinc plating is called galvanizing. (www.encyclopedia.com/articles:2000). Many alloys of iron are resistant to corrosion. Stainless steels are alloys of iron with such metals as chromium and nickel; they do not corrode because the added metals help form a hard, adherent oxide coating that resists further attack. The iron hulls of ships can be protected against rusting by attaching magnesium strips to the underside of the vessel. An electric current is generated, with the magnesium and iron acting as electrodes and seawater acting as the electrolyte. Because magnesium is above iron in the electromotive series, it serves as a "sacrificial anode and is oxidized in preference to the iron. This is called cathodic protection, since the iron serves as the cathode and thus escapes oxidation. This method is also used to protect the pipes of electric generating plants where saltwater is used as a coolant.) (www.encyclopedia.com/articles:2000). The involvement of water accounts for the fact that rusting occurs much more rapidly in moist conditions as compared to a dry environment such as a desert.

Author Eudora Welty Describes Unjust Treatment of African American Wome

Author Eudora Welty Describes Unjust Treatment of African American Women On the fifteenth of September 1963, a white man was seen setting a box beneath the steps of the Sixteenth Street Baptist Church in Birmingham, Alabama. The contents of the box: 122 sticks of dynamite. Minutes later, the makeshift bomb exploded, killing four young African American girls and injuring twenty-three other people. The white man, Robert Chambliss, paid a one hundred dollar fine for possessing dynamite without a permit. He was found not guilty of murder, and the case was added to a long list of "unsolved" bombings, police killings, and other acts of violence against the African American community. This was the world in which Eudora Welty wrote. A native of the South, Welty witnessed racism and anti-Black violence-such as the infamous Birmingham Bombing-first hand. She saw the innocent injured and slain because of the color of their skin. She watched as Black men struggled and finally gained equality -and as Black women failed to be equal within the walls of their own homes. And was Eudora Welty silent? Or did she speak out against these wrongs? Critics accused Welty of ignoring politics in her work. "Some have questioned her ... failure to lobby for the rights of blacks" (Ealy). However, Welty's portrayal of African American women in her stories highlights her belief that they were trapped in a world of injustice-a society controlled by whites and a culture dominated by men. Eudora Welty speaks through two characters, Phoenix and Livvie, and their dealings with different types of authority. Welty emphasizes the hopeless situation of African American women through her characters' encounters with the authority of nature. She creates a wor... ...ld. Eudora Welty was not silent when it came to social issues. In her own, sometimes-quiet ways, she fought discrimination and racism and inequality. She voiced her opinions and beliefs. Her stories can speak loudly of the injustices of a tainted society, but these protests are only heard by those who immerse themselves in her work, by those who reach beneath the surface to find the true meaning of the subtle events that comprise her stories.

United States Declaration of Independence and People

PLS201 Reading Notes 1 Concepts of Politics and American Politics STUDY: Lecture Notes 1, and We the People, chapter 1 Be informative, rigorous, critical. Provide specific, page-indicated references to the text. NOTE1A 15 lines.In chapter one of We the People the authors address the question of how government is made up of the institutions and procedures by which people are ruled in terms of four propositions: 1) Different forms of government are defined by power and freedom; 2) Limits on government encourage freedom; 3) Expansion of participation in America changed the political balance; 4) The goal of politics is having a say in what happens. Organize your paragraph into four or five sentences identifying the main characteristics of these concepts, as established by the authors.The authors present a concept where the amount of power the government holds and how much freedom people have defines different forms of government. When comparing a Monarchy versus a Democracy, we can clear ly see the differences within the two forms of government. Within a Monarchy, supreme power is bestowed upon one individual whereas Democracy is based on a principle of equality and freedom. The limitations placed upon the government allow the people to have a voice in politics while strengthening the principle above.This balance of power gives the people the ability to voice their opinions. Rather than being another â€Å"person† within a society, Americans are citizens who can influence the government in many ways. This expansion of participation lead to more people having legal rights to participate in politics where they can vote, send letters, lobby, and participate in protest marches and demonstrations. All of this ties back to how American Democracy, unlike many other forms of government, aims to give people a voice while developing the meaning behind â€Å"we the people. †NOTE1B 10 lines. In this same chapter one, the following section examines how the identity of Americans has changed over time, the impact of diversity and race, but in the end, the authors observe, â€Å"the country still confronts the question of who are the Americansâ€Å". Explain, please, what is this about, what is at stake, how do the authors explain it. Even though the American government focuses on the principle of equality and freedom and giving people a voice within this government, they still stumble on a simple question of who are the Americans and what defines them.The government faces a constant flow of immigrants and increasing ambiguity of racial categories raising challenging questions about politics and governing arrangements. Population growth has also spurred debates on how congressional districts should be apportioned. The paradox of the American identity is that although America is a melting pot of different traditions, ethnic backgrounds, and ideology, there are nevertheless distinctive qualities that define who Americans are. The diversity of ci tizens created what America became, a country developed from the ideas of equality and freedom. NOTE1C 15 lines.Concluding chapter one, the authors make an interesting declaration, that America is built on the ideas of liberty, equality, and democracy. They then discuss it in terms of four propositions: 1) that liberty means freedom, 2) that equality means treating people fairly, 3) democracy means that what the people want matters, 4) that American political values conflict. Okay, now, read it and summarize the main of these concepts, about 3-line each. â€Å"Life, liberty, and the pursuit of happiness,† in the Declaration of Independence exemplifies the inalienable rights which is based on the idea that all men are created equal.For Americans, liberty is â€Å"freedom from government control, and also economic freedom. † Going back to the idea of limited powers within government to allow freedom, the people have the right to alter or abolish the government to institu te a new one for their safety and happiness. When thinking in terms of equality, it can be interpreted in different ways. Equality of opportunity allows the people to reach their fullest potential and political equality refers to the right to participate in politics where every person can vote.In addition to this, political authority rests in the hands of the people, also known as popular sovereignty. The idea of majority rule with minority rights also plays a key role within the government because it allows for the preference of the majority of voters but still protects the interests of the minority. (21) Conflict helps set policies and laws because it considers both sides of any argument and prevents any discrimination against the disabled, elderly, etc. A NOTE ON FORMATThis is a 1- to 2-page, typewritten, single-spaced, font 12 reading note.
