Abstract
This paper examines how amphibians have not been exploited by humans like other animals have, they are kept as household pets and in some countries their flesh is seen as quite a delicacy. It therefore attempts to understand why are so many amphibian populations are in decline around the world. It shows how in some areas of the globe the decline is evidently due to loss of habitat but how in other areas, the reasons could be attributed to factors such as the depletion of the ozone layer or pollution. It looks at the advantages of amphibians to humans such as their use as environmental indicators and the use of their toxins as pain killers and covers methods of conservation.
From the Paper
"Habitat loss seems to be a significant cause of the diminishing amphibian populations over much of the world. Human population growth has led to many of the wetlands that are essential for amphibians to be drained for agriculture, filled in or paved. In Britain alone, many years of draining wetlands in order to improve crop yields has resulted in the destruction of 82% of marshland. Now, only isolated patches remain. Deforestation is an added strain on amphibians as the dense canopy provides shelter and protection for not only the adult amphibians but also their developing young, from predators and ultraviolet light."

"The Decline of the Amphibians
During the last 20 years, scientists worldwide have begun to notice some disturbing trends among amphibian populations. Moreover, the most troubling changes have occurred within the last decade. It seems that certain of the globe's 5,130 amphibian species have rapidly declined in number. Several species, in fact, may have already become extinct. To date, researchers do not know the reasons for this occurrence. However, some believe that atmospheric ozone depletion is responsible for the animals' decline. It could be that different amphibian species are highly vulnerable to ultraviolet radiation. Regardless of the underlying mechanisms though, the amphibians' plight may have serious implications. As "indicator" species, their decline could foretell major future environmental problems."

Abstract
This paper examines the importance of pollination services. As the author explains, the health of ecosystems and agriculture worldwide depends on pollinating services performed by particular pollinators. This paper evaluates the importance of pollinators, provides statistical evidence for vertebrate and invertebrate pollinator decline and examines causes and consequences of pollinator decline. The paper also demonstrates the consequences of pollinator decline in terms of plant pollinator interactions and corresponding research, including figures. The paper concludes that that the functional diversity of the pollination network is critical to ecosystem sustainability and productivity.

From the Paper
"Green plants represent the primary food source for a large portion of the worlds living biota. Many plants reproduce sexually and require pollination agents to ensure genetic diversity and other adaptive advantages through cross-pollination. During the search for nectar, pollen, oil, or mates, pollinators transfer pollen from male anthers to female stigmas and hence perform pollination (Cane, 2001). Due to co-evolution among angiosperms and pollinators, many primary pollinator- plant relationships are highly specific. Therefore the health of ecosystems and agriculture worldwide depends on pollinating services performed by particular pollinators. In recent decades human activates have decimated biodiversity in many different species-rich groups, including invertebrates (Cane, 2001). Declines have been recorded in many groups of pollinators including: insects, bats, birds and mammals. This decline represents less frequent flower visitation, gradual decrease of seed and fruit production, and reproductive losses in additional taxa within the community and could eventually disrupt community function (Cane, 2001)."

Abstract
This paper analyzes the challenge of changing a tourist's perception of Canada to make it a more desirable destination. The paper explains the need to reverse the trend and increase the tourism business for Canada. and looks at why Greece is a successful tourist destination. The writer suggests that more could be made of the skiing areas in Canada to attract tourists. The writer also notes that much of Toronto has been used for filming in lieu of New York City, for instance, and suggests that the names of those films be featured in tourist advertising.

Introduction
Findings
Conclusions
From the Paper
"The percentage of loss for Canada was exceeded only by the loss for Montserrat, a region suffering from volcanic explosions since 1995; Aruba, in decline since the Natalee Holloway disappearance; and Uruguay. While the drop for these other regions can be explained by various unusual circumstances, the decline for Canada appears to be more basic and to relate largely to the perception the world has of Canada as an unexciting destination. Certain specific issues can be cited with reference to tourism from the United Sates, however, such as changes in travel rules so that in the near future, a passport will be required."

Abstract
This paper reviews the book "Spain in Decline: 1621-1700," by Reginald Trevor Davies that outlines three factors for the decline of Imperial Spain: Economic and financial debilities, a military decline and a decline of patriotic and religious feelings. The paper describes the revolution in the Basque Provinces. The author states that this book of history reads like a novel.
From the Paper
"These revolts helped in Spain's decline by weakening the government's position and creating unrest in the people, so they did not trust or follow government reforms meant to strengthen the country. Too many people wanted autonomy from Spain's government, and this division left the remainder of Spain weak and unprepared for further problems, inside or outside the country. Clearly, this was an important juncture for Spain; and had they handled it with more aplomb, they might have avoided some of the unrest and division that separated the country, and helped lead to its decline in world exploration and domination."

Abstract
This paper examines the causes of the decline of the ancient Egyptian civilization and argues that a number of factors played a role. Among these are a shift from economic prosperity to poverty, the weakening power of the pharaoh (related to the rise of the priesthood and royal instability) and continuous warfare with neighbouring societies.
From the Paper
"From the Egyptian state?s origins in the Old Kingdom, circa 2575 B.C., it flourished in relative isolation from other civilizations. It was protected by the Mediterranean in the north, the desert in the east and west, and by an ?ethnic frontier? in the south (Adams, 1984, p. 38). During this time of remoteness, the Egyptian state built complex pyramid structures, developed a unique religion and established a political system based on the supremacy of the pharaoh and a hereditary bureaucracy (Fagan, 2004, p. 385). However, the prosperity and stability of the Old Kingdom (circa 2575 to 2180 B.C.) could not last forever, and since several succeeding pharaohs lacked leadership Egypt entered a period in which the central power of the government declined and local leaders became independent rulers within their own territories (Fagan, 2004, p. 389). In conjunction with this decline in power, came a prolonged drought cycle, but this led to improvements in agriculture and eventually to a rapid increase in population, though famines continued to strike for over three hundred years. Trade networks were vastly expanded during the Middle Kingdom (2134 to 1640 B.C.) and parts of the desert lands of Nubia were conquered, the first signs of imperial ambitions (Fagan, 2004, p. 390). The second intermediate period, occurring between 1640 and 1530 B.C., brought political instability and economic disorder to Egypt once again. However, in the same way that the first intermediate period brought improvements to the Egyptian civilization, this new period of instability brought several innovations that preserved Egypt?s role in the eastern Mediterranean world (Fagan, 2004, p. 391). The New Kingdom, 1530 to 1070 B.C., brought with it periods of extensive wealth, an expansive empire, and political stability, though these qualities were quickly dissolved with the last of the long-lived pharaohs Rameses III (Fagan, 2004, p. 391; Ibid, p. 395). The last years of the Egyptian dynasties were marked by a ?succession of short-lived, sometimes competing and generally unremarkable kings?(Rice, 1997, p. 1980). After this time political weakness opened the door to the rapidly evolving civilizations crowding Egypt?s borders. By about 1000 B.C. the country was bankrupt and the influence of other ancient civilizations, Assyrians and Persians followed by the Greeks, came to dominate the Nile Valley (Clayton, 1994, p. 173). The decline of the Egyptian civilization resulted from the complex interplay of several factors including economic conditions, a weakening of the pharaohs? power, and warfare with other complex societies."

Abstract
In this article the writer looks at Sparta's decline as a military power. The writer discusses the multiple manifestations of shortsightedness that caused the decline. The writer describes that this decline was caused by factors ranging from attitudes, to tactics, to lack of diplomacy with its allies.
From the Paper
"Although historians offer a panoply of possible reasons for the decline of Sparta essentially its downfall was the result of one glaring fault. This fault, although it manifested in a number of disparate ways, could be summed up in one word shortsightedness. This shortsightedness occurred in areas such as its attitudes, its failure to modify the rigid Lycurgan system, its tactical naivety, its failure to adapt when opponents began hiring mercenary armies, its wrongdoing, its lack of diplomacy ...

Abstract
This paper discusses cognitive decline in older people. The paper contends that understanding the correlation between aging and cognitive decline requires in-depth research taking into account the numerous variables and theoretical perspectives. The paper agrees that while there is certainly a parallel between the onset of late adulthood and cognitive changes, these changes need not always be severely negative. The paper examines various factors that affect cognitive change.

Retardation of Cognitive Decline
Conclusion
From the Paper
"Cognitive decline in older people is most likely to be measured and seen in terms of declarative or episodic memory. (Wilson et al., 1997. pp 7-14).This refers to the ability to learn and retain new information. Other factors that are measured in this age group, and which show evidence of decline, are mental processing skills and perceptual speed. This refers to simple perceptual comparisons which are unusually measured with accompanying time-related tasks. (ibid) People, who are diagnosed as having ARCD or Age Related Cognitive Decline normally are perceived as suffering from deterioration of memory and learning abilities as well as limited language attention span and concentration problems."

Abstract
The writer explains that although the United Kingdom's economy ranks among Western Europe's largest, its industrial sector employs only 18 percent of the workforce, and has experienced a steady decline since World War II. The paper examines several reasons for this decline. In conclusion, the paper shows that the English economy has moved from manufacturing to finance and new technology.
From the Paper
"Expansion in old industrial regions such as northeast England, south Wales and central Scotland, based on coal, steel, shipbuilding and mechanical engineering hinged on the imperial dominance of British manufacturing. The decline of the British Empire was reflected in collapse in these sectors and de-industrialization there as well. In the 1960s, decentralization from core regions of the British economy-the West Midlands and the southeast part of the nation, and large urban agglomerations-coincided with a large, growing investment by the government in UK based companies overseas. A new layer of economic growth was added as a result, but a layer that could not accommodate such growth. The result was growth being added to peripheral regions through branch plant operations of multinational corporations. These corporations were attracted by the prospect of good investment capital, regional policy and a plentiful labor reserve. This overlapped the declining heavy industrial complexes that were not able to cope with heightened international competition. In other words, existing manufacturing plants operating on home soil were being forced to compete with companies from other nations using the same soil for manufacturing. In the 1960s, manufacturing investment absorbed less than 4 GDP, a rate lower than all other European countries. Ministers in government, eager to achieve growth, were more prepared to expand growth and achieve higher demand found that the investors and population did not have the same enthusiasm."

The Decline and the Fall of Rome, 2002.
This paper examines three of the major factors that contributed to the decline of the Roman Empire.
1,650 words (approx. 6.6 pages), 9 sources, $ 62.95

Abstract
These three factors are the division of the Roman government into warring factions, the increase of a "barbarian" populace from the European territories, and a decline in the rights of the Roman people that eventually lead to economic failure and public dissent. Examined separately, these factors can be seen as manageable, where no one factor would have truly lead to the decline of the great Roman Empire.

Abstract
This paper presents a consideration of the economic decline of Spain under the rule of Philip II, in the late 16th century. The paper discusses the major issues involved in Philip's mismanagement of the economic and foreign policy of Spain that contributed to the decline. The problems of inflation, foreign wars, debt and lack of Spanish productivity are highlighted.
From the Paper
"When Philip II ascended to the throne of Spain in 1556, by all appearances he was the wealthiest king in the Western Hemisphere. Spain had, since the beginning of the 16th Century, extended its kingdom over much of the Mediterranean and it was the leading power in the race to colonize the New World of the Americas. It appeared that Philip II had inherited a financially powerful empire from his father, Charles V, and was set to govern a growing and important nation into an era of riches and conquest (Elliott). However, by the time he abdicated the throne in 1598, Philip II had overseen the disastrous decline of Spain's wealth and prominence, resulting in a bankrupt and weakened nation and a crumbling empire (Kamen). This research paper will consider the factors that led to the economic decline of Spain under Philip II's rule."

Abstract
This paper discusses the important issue of the decline in immigrant health. The paper discusses the healthy immigrant effect, which has been noted by numerous researchers as a phenomenon where the health of immigrants who first arrive in Canada is far better than that of the Canadian born population but then their health status declines. Also it is highly important to note that there is extensive diversity among groups of immigrants pertaining to health status.
From the Paper
"Decline in Immigrant Health The decline in immigrant health is a most significant issue. The healthy immigrant effect has been noted by numerous researchers as a phenomenon where the health of immigrants who first arrive in Canada is far better than that of the Canadian-born population but then their health status declines (Kobayashi, 2003; Hyman, 2004). Also, it is highly important that there is extensive diversity among groups of immigrants pertaining to health status. The diversity is related to power relations, to all of the determinants of health, but most especially to income and social status. "
