The tolerant level is sky-scraping, a lot of gratuitous area will be incorporated and the diminution in searching area is not very considerable; on the other hand, if the lenient level is low, we have the risk of ignoring the main area. The brightly brown color captures awareness to the customers. The billboards exhibit great advertisements to fleeting pedestrians and even drivers. Characteristically, screening outsized, apparently amusing slogans, and distinguishing visuals. The billboards are exceedingly noticeable in the summit in market places.

The Impact Of Tourism On Water Consumption Tourism Essay

The Impact Of Tourism On Water Consumption Tourism Essay Tourism is the major economic sector for many countries around the world especially for small island developing states. . The major growth of the tourism industry started in the 1980s culmination increasing coastal development with major investments in hotels Mauritius is now a well established high class tourist resort destination and tourism is the third pillar of the Mauritian economy after the export processing zone manufacturing sector and agriculture. It contributes significantly to economic growth and has been a key factor in the overall development of Mauritius. In the past two decades tourist arrivals increased at an average annual rate of 9% and in 2000, gross tourism receipts contributed about 11% of the GDP of Mauritius. (CSO, 2007)) The plan of the government is targeting 2.0 million tourists from 2015 to 2020. The strategy for the development of the Tourism sector takes its base in the Tourism Development Plan (2002). It presents a twenty year vision which sees the tourism industry growing but ensuring that environmental and social issues are addressed to the benefit of the people of Mauritius (Min .of Environment and NDU). The Action Plan includes private sector investments in tourist accommodation, tourist attractions, and ancillary facilities, public sector investment in tourism support programmes (e.g. roads, car parking, water and sewage schemes), infrastructure and critical tourism product improvements, diversification and innovations, human resource development/social projects and environmental management support. There will be an accompanying demand for services for high quality up-market tourists with specially trained staff and hotel rooms including trained tour guides and support services such as flight bookings, airline operations, etc. Tourism and water The industry is also a major consumer of water resources and impacting heavily on water demand of island states. The problem of water supply is further exacerbated by the impact of climate change. Tourism industry relies also on a safe and reliable supply of water. With the goal of attracting 2M tourists by 2015 in Mauritius the intensive tourism development that will follow will have a major impact on our natural resources (CSD, 1996). It has been growing rapidly and impacting on the natural resources of the host countries. Overexploitation of water resources can impact negatively on ecosystems which are major components of its tourism industry. Competition for water resources by the tourism sector and domestic population is a global problem exacerbated by the climate change (Goodwin, 2007). Mauritius is facing each year prolong drought problems during the dry season where it is also the peak tourist period. Over extraction and lowering of ground water table can lead to eventually the depletion of aquifers as it is not replenished as rapidly it is consumed. Pollution from sea water intrusion will further limit the availability of freshwater. The latter will be more apparent with sea level rise due to global warming (Goodwin, 2007). The tourism industry faces two issues with regards to water as a resource namely how it affects distribution of water and secondly the impact of the industrys consumption on the environment and the availability of water (Goodwin, 2007). For the development of large resorts, especially in water scarcity areas, the water available for the local people is deviated to provide for these resorts (Goodwin, 2007). In many places water is diverted to provide for tourists and thus leaving indigenous population short of water. European Environment Agency (2003) in its assessment reported that tourists consume up to 300 Litres (up to 880 Litres for luxury tourism) and generate around 180L of wastewater per day. The number of tourists visiting particular places is season dependent and is not constant all year round and tends to be concentrated in places which have limited water resources (Garcia and Servera, 2003). There are conflicts of interests as the tourism industry is able to buy water at higher prices whereas the poorer population will have more frequent water shortage (Goodwin, 2007). In Tunisia groundwater resources that were important for agriculture were diverted to provide for the tourism industry and thus creating a new problem of dried out land that are unarable and had to be abandoned. The European Tourism Study Group report 2007 conclude that hotels are high consumers of water, as a tourist staying in a hotel uses on average one third more water per day than a local inhabitant. The desalination of sea water on a large scale is a measure affordable to countries with high revenues such as United Arab Emirates and Maldives which have oil resources (Dluzewska, 2008). LAND USE PATTERNS in Tourism: Tourism is being given special attention with respect to its actual and potential impacts in land use (Rico-Amoros, et al., 2008). The tourism distribution is not homogenous for many countries and the different forms and types of tourism have different water requirement (Gossling, 2001). Water consumption by the tourism sector is not well documented by statistics at present. More complete information on water demand of tourism and its different subsector ( second homes, facilities, activities etc,) is needed by state and local authorities to define priorities for water conservation or demand management programs ( Hof. et al, 2011). Rico-Amoros et al. (2008) mentioned that the development of tourism in Mediterranean region is enhancing pressure on water demand because there high numbers of tourists at specific period and summer droughts which further decrease the availability of water. However, from closer study of the different type of tourists, Rico-Amoros et al (2008) found out tha t concentration of tourists such as in hotels tend to use comparatively less water than disperse, low density residential resorts. Hof and Schmitt (2011) found out that increase water consumption is directly related to the low-density residential tourist land use due to outdoor uses such as swimming pools and gardens comparing with tourists in hotels. The research of Hof and Schmitt (2011) concluded that in summer 70% of the total water consumption in the residential tourist areas is used for gardens irrigation which has been identified as the main cause for increase in water consumption. The additional pressure on water use is from individually own swimming pools which accounts for 22 litres/person/day as shown by Hof and Schmitt (2011). Hotels with golf courses were analysed for their water consumption patterns and regression analysis demonstrated that the size and price were important factors that will influence the water use by golf courses (Gopalakrishnan, 2003). Resorts and ho tels golf courses are heavy water users and for small islands the problem is urgent as there is limited resources of drinking water, and thus the water must be judiciously managed ( Graefe and Vaske, 1987). Benchmarks for water use in guest rooms in litres per guest night Good Fair Poor Temperate 250 250-300 >300 Mediterranean 270 270-320 >320 Tropical 300 300-350 >350 Source IBLF WWF-UK (2005) p.19 Mauritius as SIDS: its vulnerability Small Island States are mostly dependent on their natural environment for promoting tourism development but paradoxically the tourism development appear to be a fast track to social and economic development and thus little care is given for the ecosystem (CSD, 1996). The environment impacts of tourism are more consequent in Small Island States due to its limited land space and freshwater resource. Land is use to build infrastructures and facilities for tourists along with hotels and the new trend of residential houses or apartment. Rising prices of building land increase the pressure to build on agricultural land as the tourism sector is more lucrative. In many countries including Mauritius, there has been unchecked construction along the coast whereby the original pristine beauty of these areas has been changed in favour of urbanization since the development of the tourism sector (CSD, 1996). It is only recently that governments are taking measures through legislations to protect th e natural resources and promote sustainable. development. Over the past years, there has been a drastic increase in water demand from the different economic and demographic sectors, which in general is leading the country to a water stressed situation. Mauritius and its water resources According to the United Nations Development Programme (UNDP) Human Development Report, Mauritius is already facing a situation of water stress because it has a supply of 1083 m3 per person per year (based on actual population), which is below the norm of 1 700m3 per person per year. Mauritius is expected to suffer from water scarcity by 2020 with a projected supply of 974 m3 per person per year (based on a projected population of 1 335 000). Although the figures can be interpreted in various ways, they provide an indication of the problems that Mauritius may face in the future regarding water supply. The water sector faces a number of challenges resulting from increasing demand from the different sectors. New dams are planned to be built and reduction in unaccounted for water are being envisaged with big investment in new pipe networks. Diversification of the tourism product-IRS in Mauritius In view to attract more foreign investment Mauritius has recently introduced a new type of development namely the Integrated Resort Schemes (IRS) whereby resorts are being constructed that include hotels, residential villas and golf courses. Since 2005 there has been an increase in the number of resorts and golf courses though the financial crisis has put a halt to this rapid increase. These developments have put further pressure to the scarce water resources. In Mauritius strategies are being put in place to manage the water resources the demand as well as the supply sides. The IRS promotes the concept of residential tourism with second permanent homes for rich retired or rich celebrities. This market diversification has therefore allowed the development of golf, villas, spas and also permanent second homes or residential that have increased the demand of water from the tourism sector. In encouraging this type of development and targeting more and more tourist this will again have a consequences on the water resources. Mauritius depend on a few number of reservoirs and are already under pressure to supply for the domestic, industrial, agricultural and tourism sector. The tourist hotel mainly the large ones have started to have desalination plants to have constant supply of water. Due to high water demand Mauritius has reached almost its limits in terms of underground resources. The table below shows the water requirements till 2050. Table 1:Water requirements in Mauritius (Proag, V., 2006, Water Resources Management in Mauritius. European Water 15/16: 45-57) Available Water resources and climate change could however have an impact on the diversification strategy thereby causing a decline of growth in the tourism sector especially if these water crises are not well managed. (Essex et al, 2004) Residential Tourism or second homes The different types of tourist accomodation and new type of residential tourism do not consume water resources similarly. The golf courses are consuming more and more water for irrigation purposes. A.Hof et al (2011) have shown that outdoor uses such as swimming pools, garden irrigation are also have a high impact on water resources. As determined by a study (Gopalakrishnan and Cox 2003) shows that number of units of swimming pools and golf courses will determine the consumption of water. Aim of paper To develop appropriate strategies for the management of the water resources information on the tourism sector demand for water and the different usage will be required. There is however an information gap with regards to its impact on water resources . This paper will try to show the influence of tourism: hotel, non hotel and residential on the scarce water resources and thereby assist in developing a strategy for a sustainable tourism.

Environment Primary Factor That Influences Plant Growth Development Biology Essay

Environment Primary Factor That Influences Plant Growth Development Biology Essay Although there is no doubt that the world population grows up in more gradual way every year, demanding more food than any other time before, Environment is the primary factor that influences the plant growth and development and has also the greatest effect on the crop distribution on the earth. In this ten page report, the most important environmental factors that affect the crop growth and development namely light, water, temperature and carbon dioxide are covered, emphasizing their influences on crop productivity. Moreover light as the most environmental factor importance on crop production and productivity, all light quality, quantity and duration effect directly on crop yields, also in most cases plant reactions and processes are greatly influences by the temperature, plants key process affected by temperature is photosynthesis followed by germination, transpiration, respiration and flowering. However, crop temperature requirements in a specific physical, chemical or biochemical process varies from one spice to another resulting difference among crops in their geographical distribution. On the other hand, water and humidity play an important role for the crop productivity since most plants need 90% water content to grow effective and efficiency way until some crops like rice demand flooding the area to grow properly. In addition to the plant water needs, plants are number one consumers of carbon dioxide on the earth so as to synthesize food and energy. Each of these factors were discussed in this report emphasizing and giving more detailed look on their effect on crop productivity. Light Why solar energy is important to a successful plant growth, development and improvements to its yields? On the planet life is mostly solar-powered, sun is the only natural source of light energy, all the living organisms depend on the amount of light energy (solar radiation produced by the sun) harvested by green plants at any level of ecosystem, only few types of bacteria can derive the energy they require from sulfur and other inorganic chemical compounds or substances. Photosynthesis which is the process that the plants manufacture their food molecules from carbon dioxide and water by using the sun light, therefore the rate of duration of photosynthetic activities directly effects the amount of dry matter produced by the plant, and energy harvested as crop yields to transfer energy from primary producers to the other components of the ecosystem which are the consumers, so the ultimate source of food in the globe is the green plant, because plants have the ability to harvest and ut ilize the sun light manufacturing a usable food after three main consecutive processes during plants photosynthetic activities. Photosynthesis The management of that resources available to the production, that the crop requires to grow and develop and show its potential genetic characteristics as much as possible is a major factor that contribute the dramatic rise of the crop production, only organisms/plants that contain a certain pigment called chlorophyll which is the most abundant enzyme/protein on the earth are capable to utilize solar energy directly. It is therefore; light is an important factor to produce energy by the plants and the energy produced will be supplied to the different levels of the ecosystem. The light influence on the plant development and productivity can be discussed into three main categories. Quality of light The intensity of light and its concentration are what decide the quality of light; light densities differ from one season to another, countries that have three or four seasons, the largest amount of light is found in the summer season, where the least amounts are available in the winter, as the case is in many European countries, but areas like Malaysia the amount of light available throughout the year is almost the same, so the light intensity varieties depend on the geographical area, for example in Sub-Saharan Africa where the climate is desert, clouds and other sun light barriers are not found in the atmosphere, the sunlight density is very high. Not straying from the main point, the more light radiation that a plant harvests, the greater and the ore ability to manufacture food through photosynthetic processes even though this relationship will depend on the pathway group that a certain plan flows. From this interactions, the scientists specially those botanists, ecologists and physiologists realized the direct relationship the amount of light available to the plant and the crop productivity, that is why the greenhouse managers to fix artificial light sources to supply light their fields to create longer photoperiod in the greenhouse targeting more improvements to the final output, even though this strategy will negatively affect the cost of every unit produced under this system. However, they can easily manipulate the amount of light of the planned growth patterns to their plants. Quality of light Are there different light qualities? Light colors, which can be divided into bands of red, yellow, blue, orange, violet and indigo. The red and blue color lights that the plant can absorb have the biggest influence on crop growth, the blue light is primarily responsible to the leaf vegetative growth and the combination of red and blue lights encourage the flowering process. The solar rays produced by the sun, or what is normally known as wavelength of the light constitute the light quality, wavelengths that the sun sends to the earth ranges 250 7000 nanometers, these solar rays reaching the earth are divided into eight parts, only the visible radiation is called light, and the other which are Cosmic rays, Gamma rays, X-rays, Ultraviolet, Infrared, Microwaves and Radio waves are invisible. The visible solar rays or light is the small proportion of the range of wavelengths of the electromagnetic radiation occurring somewhere between 400 and 735 nanometers. In other words the visible light is between Ultraviolet which are shorter waves than 390 nanometers and Infrared which are longer waves than 700 nanometers. Only 47% of the light produces by the sun is gained by the earth (P. Bannister 1978), where the other 53% part of it is absorbed by the atmosphere while other part is reflected by some barriers and finally gained by the space. Only 2% of that 47% o f the light that reaches the ground is used in the photosynthetic processes and about 10% is used different processes that occur in the plant. Duration of light Photoperiod or the duration of light is referred to how long of time the plant exposes to light, the flowering of many plant species is controlled by the photo duration, as a result that, the plant physiology experts tend to name and classify plants into short-day and long-day plants relating to under which condition do these crops flower. In contrast, the duration of uninterrupted darkness which presents a critical situation to the crop development and flowering process is the factor that show the importance of light duration not only the plants but also on farm animals specially poultry production therefore shorter darkness periods are encouraged. The amount of carbon dioxide fixed and assimilated by a specific plant is determined by the light density, because several situations can be seen when the plant is grown the area where the light intensity is not constant this is much explained in the plants light response curve, which shows light compensation point, plant light response area and plants light saturated period where any further increases of the light available to the plant will not result an increase in the amount of the carbon dioxide absorbed from the atmosphere, meaning photosynthetic activities will peak t that point and all the enzymes involved to this process are active. From this concept, the ecologists realized some remarkable differences among the two main pant pathway groups C3 plants, C4plants. Because the carbon dioxide concentration is not the same in these pathways as soon as there are variations in amounts of light available (lower, neutral and higher) the different light amounts are available to the cro p, the growth, development and productivity are highly effected by the light factor. In addition to that, C4 plants showed higher net rate of photosynthesis as a result of light intensity increases than C3 plants. Even though at a very low light intensities C3 plants are more affective and efficiency than C4 plants because of their low compensation points, crops like corn and sorghum full sunlight for photosynthesis while tobacco can tolerate only partial sunlight. Water Water is the most component in the living cell, plants contain nearly 90% of water content , this high percentage enables us to understand the remarkable role of water on the crop growth and development, large quantities of agricultural output all over the world is heavily depend on different types of irrigation, over 1500 million hectares of agricultural land are irrigated every year, the continuously rise of the global temperature is seem to be the highest impact on the irrigated agriculture when considering water (hydrological) cycle. Water in a primary component in plant photosynthesis, the plant respiration, responsible to balance the pressure (turgor) in the plant cell, turgor is required to form the cell shape, tissue firmness and fullness, and ensure cell development. Also water is the place and the solvent where carbohydrates and minerals are transported from the soil and/or leaves to the other parts of the plant. Water treats as a cooling system to regulate the plant temperature specially on the leaf surface through a process called transpiration, water controls the stomata opening and closure, water provides a kind of power to encourage roots to penetrate the soil more in depth and this will enlarge the space that the crop can absorb the nutrients needed for growth and development. One more crucial role is that the water is the medium where biological reactions take place, also water is a component in the organic reactions, and it is used in the cell growth. Amount of water available in the plant compared the atmosphere water content (atmosphere humidity) is the limiting factor of crop photosynthesis, the ratio of the amount of water vapor available in the air to the volume of water that the air can keep at specific temperature and pressure is called relative humidity. Water vapor is the whenever a water molecule leaves from the surface of the ground, it is said to have  evaporated. Each individual water molecule which transitions between a more associated (liquid) and a less associated (vapor/gas) state does so through the absorption or release of kinetic energy. On the other hand, In the hot climate, wind and dry air conditions while there is a moisture stress or what scientifically called water deficit caused by the low water content, in this situation the stomata aperture is dramatically reduced and the photosynthetic reactions are weakened because the activeness and the effectiveness of the enzymes have a direct proportional relationship to the amount of water found from the s urrounding environment and inside the plant tissue and indirectly proportional to the temperature specially the extreme one. Temperature As said in the beginning temperature is important factor to the plant growth, development and yield, since it affects approximately most of the plant processes including germination, photosynthesis, respiration, transpiration and flowering. As the degree of temperature increases this will result an increase to the plant respiration and photosynthesis. Generally in temperate species, the increase in temperature about 10oC (18oF) will cause to the rate of carbon dioxide (CO2) assimilation approximately to double. Furthermore usually plants in the tropical areas require higher temperature degrees to perform successful photosynthetic processes to the possible maximum level that the plants in the temperate areas can generate. Usually, plants differ their temperature requirements for example radish, spinach and lettuce which are cold weather (season) crops germinate at 55oF 65oF best, where crops like petunia, lobelia and tomato which are hot climate crops germinate at about 65oF 75oF best. According to the level of the temperature, plant processes can speed up or slow down the period that each activity completes. For instance, the 18 months that the oil palm plants need to live in the nursery can be reduced to about 10 months when provided higher temperatures from artificial sources. Flowering however, experts in horticulture sometimes relate the length of the day to the temperature to manipulate flowering. For example the combination of short days with low temperature degrees helps cold-season plants to the set the flowers as the case in Christmas cactus, when the temperature levels are in their highest points and the days are in their longest hours the summer (cold-season) crops will bolt as in the case in spinach. In contrast, when the temperature is extremely cold, plants like tomato which is warm climate crops will set their fruits in unsuccessful manner. Temperature influence on biochemical plant processes Biochemical reactions of the plant are directly affected by the temperature through one or two principle functions, an exponentially dynamic increase to the rates of proceeding activities. And sometimes as the climate gets hotter more exponential delay will be experienced resulted by enzymes lost their naturalness. The most important and involved factor is the weather, it is not impossible to rise the quality of enzyme stability so as to avoid losses in their naturalness. The everyday changes on the temperature is called thermo-period the best crop growth occurs when the difference between the day and night temperatures is about 10 to 15o C. under this situation plant build up their food and break down the energy, higher temperatures than that required by the crops cause some crops to photo-respire and the amount of food manufactured by the photosynthesis will equalize the energy used to at that time and carbon dioxide CO2 assimilated will be zero meaning that the crop is in the state of light compensation point. Therefore food molecules synthesized from the photosynthetic activities must overweight the energy that the plant consumes otherwise the plant will grow poorly resulting drops in the ultimate yields. Higher temperatures and their long-term influences on the crop The chronic effects meet the crop growth and development when the temperature is getting higher every day the crop stress will become more serious because of the extreme hot weather. However C4 plants showed a higher net rate of photosynthesis than C3 plants when temperature levels at the surface of leaves were increased. In 1993 Kropff and his colloquies, found that 9% decrease of rice productivity were recorded for every 1o C increase of the temperature, the Intergovernmental Panel on Climate Change (IPCC) coordinating with the Food and Agricultural Organization of the United Nations (FAO), their second evaluation report in December 1995 forecasted that the temperature of the planet will rise about 2 5oC during 21st century and the sea level will grow up about 30 t0 100 cm more, and this higher sea levels can submerge many agricultural areas in the world, these weather conditions will negatively affect the food production in the globe. Carbon dioxide When crops are manufacturing their food through photosynthesis, carbon dioxide is the most component factor importance in that process, plants obtain CO2 from the air through the pore spaces on the surface of the leaf when open, CO2 flow in the plant tissue depends on the carbon dioxide concentration inside the plant and the plants surrounding atmosphere, the carbon dioxide molecules (substances) move inside the plant when the concentration inside is less density than its concentration outside and this is a physical process called diffusion. The carbon dioxide flow in the plant is controlled by the stomata then the pore spaces on the leaf surface are open, and the aperture of the stomata its turn depends on the amount of water available in the guard cells. Overview of carbon dioxide influence on plant growth and development Plants are divided into two main categories according to their response and their first stable product after the fixation of carbon dioxide. The first category is those species whose first stable products after the fixation of carbon dioxide is three carbon molecules and the plants under this group are called C3 plants or C3 pathway. The second group is the species that their first stable products after the fixation of carbon dioxide are four carbon molecules and plants in this group are called C4 plants or C4 pathway, also there are CAM plants, these plants have different character, because the plant here operate fixing carbon dioxide in dark, plants depend on the amount of carbon dioxide accumulated in the leaf in the night. The photosynthetic rates of the plant directly relate to the growing amounts of carbon dioxide until it reaches approximately 700 ÃŽ ¼ mol/mol or higher according to the plant type and other factors. Furthermore photosynthesis always develops with the rise of temperature to optimum levels and after specific maximum level the photosynthesis in C3 plants show decline, as a result of photorespiration process which takes place in the plant. As some scenarios of the world climate change mentions, a global worming is forecasted and that will increase the amount of carbon dioxide available in the atmosphere as well as other gases in the green house. Mean while the amount of rain in many places of the world may also experience changes, generally scientists believe that certain plant species will indicate yield increase especially in C3 plants (C3 pathway includes many important crops like wheat, rice, oats, soybean, pea, peanuts, sunflower and tomato) because of the CO2 increase. However, benefits of increased carbon dioxide concentrations in the atmosphere are limited, because stomata close and photosynthesis stops at CO2 concentrations higher than 0.15%. On the other hand, C4 plants which include coin, sorghum, sugarcane and millet and many other crops are more efficient in higher bright-nesses and higher temperatures than C3 plants even though the reverse is true when light intensity is very low. Soybean responses different amounts of CO2 As IPCC and FAO reported in their second assessment in December 1995, the amount of production harvested from soybean fields was generally increasing by the elevated CO2 levels Allen et al. (1987). The following table shows the percentage increases of soybean yield predicted across selected carbon dioxide concentration ranges associated with relevant benchmark points in time, adapted from Allen et al. (1987). Period of time (years) [CO2] midday Biomass photosynthesis Seed yield Initial Final (Nmd/mol) (% increase over initial [CO2]) IA 17001 200 270 38 33 1700 1973 270 330 19 16 1973 20732 330 660 50 41 1 IA, the ice age is about 13 000 to 30 000 years before present. The atmospheric CO2 concentration that prevailed during the last Ice Age, and from the end of the glacial melt until pre-pioneer/pre-industrial revolution times, were 200 and 270 ÃŽ ¼ mol/mol respectively. 2 The first world energy crises occurred in 1973 when the CO2 concentration was 330 ÃŽ ¼ mol/mol. This CO2 concentration is used as the basis for many CO2 doubling studies. The CO2 concentration is expected to double sometime within the 21st century. Conclusion Crop production and productivity entails the management of production resources, since the world population increases demanding more food and fiber the need of utilizing the sunlight energy, water, temperature and carbon dioxide is important since plants are the ultimate source of energy for all lives on the earth. We humans and other animals cannot utilize the solar energy, only organisms that contain chlorophyll are able, but we are capable to give more attention to the factors that affect photosynthesis. The management, conservation and protection of water, land and atmosphere are the most challenging issues to realize higher and stable crop yields. In the future, the main that the researchers discuss will be to identify and select plant species that have the ability to perform more photosynthesis and carbon dioxide assimilation for higher dry matter production. Also when more is understood from influences of the present climate changes on plant production and productivity, much money, time and effort should be invested to introduce cultivars that can adapt the environment biologically and systems to contribute the management of crop production to create more stable, sustainable and productive agricultural models.

Shelleys Frankenstein and Austens Mansfield Park as Vehicles for Social Comment :: comparison compare contrast essays

Shelley's Frankenstein and Austen's Mansfield Park as Vehicles for Social Comment It has been often noted that the Romantic writers of English literature were rebelling against the established positions and views of society. Most of the Romantic artists were indigenes of the well-established middle class and they were swiftly tiring of the self-serving political depredation perpetrated by the hands of the upper class. The Romantics were flouting convention, thumbing their noses and calling for radical and widespread reform not only in governmental politics, but within the politics of their own trade--creativity and art. Their myriad of works are clear evidence of this. Contumely against established society was found mostly in the poetical works of the day. However, much social commentary found its way into seemingly unlikely novels. Two such novels are Mary Shelly's Frankenstein and Jane Austen's Mansfield Park. Both of these novels are clever repositories for social commentary and judgment. The overwhelming social judgment by Austen and Shelly was an intolerance for class distinction. Though they were hardly deluded enough to posses Utopian ideals, they nevertheless felt that a society with very little class distinction and especially without class-specific opportunity and quality of life was indeed attainable. Given that Karl Marx formulated many of his socialist ideals as a result of his exposure to the conditions of working class Englishmen, one might venture to say that the Romantic artists were forerunners of the socialist ideal, though perhaps this is a stretch. However, neither Austen nor Shelly saw socialism as an antidote to class distinction, or if they did, it did not find its way into their novels. They were quick to show, though, that a class blending could occur that was acceptable to all. In fact, such a theme is clearly prevalent in many sections of both Mansfield Park and Frankenstein. For example, in Frankenstein, Shelly describes the acceptance of a lower class individual into an upper class family. Justine is a lower class servant who is taken into the Frankenstein family to alleviate the dire straits into which she has fallen. However, the Frankenstein's do not view her as a servant in the typical, expected sense. Rather, in a letter to the maniacal, creature-creating

Declaration of Rights and Sentiments :: essays research papers

Many Americans realized their own oppression as they worked to the end of the institution of slavery. When two of these women, Elizabeth Cady Stanton and Lucretia Mott, were denied the right to sit as delegates at the 1840 World Anti-Slavery Convention in London, they were angered to the point of action. Eight years later in Seneca Falls, New York, the first American women's right convention was held. Elizabeth Cady Stanton presented the following declaration. When, in the course of human events, it becomes necesary for one portion of the family of man to assume among the people of the earth a position different from that which they have hitherto occupied, but one to which the laws of nature's God entitle them, a denet respect to the opinions of mankind requires that they should declare the causes that impel them to such a course. We hold these truths to be self-evident;that all men and women are treated equal; that they are endowed by their Creator with the certain inalienable rights; that among these are life, liberty, and the pursuit of happiness; that to secure these right governments are instituted, deriving their just powers from the consent of the governed.Whenever any form of government becomes destructive of these ends , it is right of those who suffer from it to refuse allegiance to it, and to insist upon the instituiton of a new government, laying its foundation on such principles, and organizing its powers in such form, as to them shall seem most likely to effect their safety and happiness. Prudence, indeed, will dictate that governments long established should not be changed for light and transient causes; and accordingly all experiences hath shown that mankind are more diisposed to suffer, while evils are sufferable, than to right themselves by abolitionist the froms to which they were accustomed .

Lost City of Z

Non-Fiction Literature Circle by Aidan Morrow Author: explained in presentation Audience: This book was written for an older audience of anyone who would love a good tale of adventure. This is because of the novel’s length and due to the fact of the death and sadness that finds its self in this book. Argument: A cautionary tale about over reaching ones personal limits, very much like the story of Icarus. Evidence: The evidence of the books truths are strewn upon the last 80 pages of the book.This novel has an extensive bibliography on many important facts in this novel. What’s left out: The rubber boom should have been explained more. It was the reason for most of the Indians death and would have played a part of the background story of the Indians. Most compelling quote: â€Å"Starvation sounds almost unbelievable in forest country, and yet it is only too likely to happen. – Percy Harrison Fawcett† Implications of your learning: Now after hearing this sto ry of Percy I care about finding him and the lost city of El Dorado (lost city of Z).With modern medicine and modern technology there must be a way to solve all the unanswered questions left by this book. Connections to other readings: One of the main connections to other readings I found was the story of Icarus. Icarus's father Daedalus, a talented and remarkable Athenian craftsman. Daedalus fashioned two pairs of wings out of wax and feathers for himself and his son. Daedalus tried his wings first, but before taking off from the island, warned his son not to fly too close to the sun, nor too close to the sea, but to follow his path of flight.Overcome by the giddiness that flying lent him, Icarus soared through the sky curiously, but in the process he came too close to the sun, which melted the wax. Icarus kept flapping his wings but soon realized that he had no feathers left and that he was only flapping his bare arms, and so Icarus fell into the sea in the area which today bears his name, the Icarian Sea near Icaria, an island southwest of Samos. A question for discussion: Do you believe that Percy could have found the lost city if he had Alexander Rice Jr. ’s funds for his exhibition?

Bamya- Egyptian Food

Food and Nutrition ISP World cuisine Egypt Alex Easton The news of the Egyptian or lotus revolution has headed the media world-wide a few months ago. An uprising of the middle class Egyptians has led to overthrow the notorious Hosny Mubarak who had reigned Egypt for 30 long years. The Egyptians have overcome their fear of authority and had reached the point of no return. Unemployment, poverty, hungry and poor Egyptians now seek a better future for their country and for themselves. The Arab Republic of Egypt is a link between Africa, Europe and Asia.Egypt is located in the northeastern region of the African continent. Egypt has three major water resources, the river Nile, the longest river in the world, the Mediterranean Sea and the Red sea, however, only the river Nile provides palatable drinking water. Despite this, Egypt's climate is arid and dry and most of the country receives less than one inch of rainfall each year. The Mediterranean Sea may offer Egypt's northern coastline up to eight inches of rainfall each year, and keeps year –round temperatures cooler than the inland deserts.The widespread lack of rainfall makes it extremely difficult to grow crops. Egypt has no forests and only 2 percent of the land can be farmed. The river Nile runs from the south to the north of eastern Egypt and empties into the Mediterranean Sea at the delta, the most fertile land in Egypt. Around 95 percent of the countries population lives alongside the Nile River, including about 3 percent of Egypt's population in its capital, Cairo. This overcrowding is threatening Egypt's wildlife, recourses and water supply.The Egyptians still have a love of food inherited from their ancestors. Living on a fertile land that yields different fruits and vegetables all year round has enriched the Egyptian kitchen with a variety of food. Animals also show a variety, with different types of meat present; beef, veal, lamb, poultry and even camel meat is popular. The unique Egyptian cuisin e has been influenced by other neighbouring cuisines, Middle Eastern Turkish, Greek and Roman cuisines have influenced some of the Egyptian dishes available now. The Egyptian cuisine is also affected by the season's products.Bread and rice are present all year round as the wheat is made into flour and together with rice is a strategic grain in the kitchen. The varieties are in the selection of fruit and vegetables. Oranges, tangerines and citrus fruits are abundant in the winter starting from November, while watermelons, melons, mangoes and apples are available in the summer. The main vegetables available in summer are okra and molekheyia-a leafy green vegetable that is shredded and made as a soup. Potatoes, eggplants and other vegetables are available all year round.Despite the fertile land and the variety of crops, the Egyptians mostly are in poverty and in hunger . Food prices are at record levels partly due to population growth and increased demand from a recovering global econo my, tight supplies, high oil prices, and weak agricultural planning and production attributable to climate change-induced natural disasters and crop loss in key producing nations. The Egyptians are now trying hard to change the policies that were available in Mubarak's regime. The Egyptian revolution was ignited by a poor mans own will to burn himself in front of parliament as he could not feed his family anymore.Thirty years of government corruption, bribery and suspicious alliance with outside nations caused the Egyptians to rebel as they repeated â€Å"enough, enough†. The previous policies of Mubarak's government had impovered the Egyptian farmer and peasant, abolishing wheat farming, and accepting wheat from the USA, caused this uprising as bread prices had raised. In 1999, agriculture made up approximately 16 percent of Egypt's economy, employing about one-third of all Egyptians. However, Egypt's agriculture is also contributing to the slowing of economic growth. A shor tage of arable land (land that can be farmed) has become a serious problem.The lack of farmable land has caused Egyptian farmers to move to other countries. Egypt, struggling to consolidate a revolution that deposed President  Hosni Mubarak  in February, now faces what could be even worse turmoil because the country is running out of food as well as the money to buy it. Food prices went up 10. 7 percent in April compared to the same month in 2010, government statistics indicate. According to Al-Ahram, Egypt's leading daily, hoarding of rice by wholesalers has pushed prices up by 35 percent this year. Egypt is reported to have only four months' supply of wheat on hand and only one month's supply of rice.Egypt faces daunting challenges as it prepares for broad presidential and parliamentary elections within a year. Ongoing volatility in global food prices will strain resources during this critical transitional period. Still quite vague what the new government will do, the present change to democracy and the upcoming parlimental and presidential election is giving the Egyptians hope to a better future. Egypt is entering a new era, an era of real democracy and the will of its people, especially the youth to transform their country and create a new environment for prosperity.
