Abstract
The book "Man and Nature", written by John Marsh in 1864, played a significant role in initiating the conservation movement in the United States. The paper explains the message set forth by Marsh in his book. It then takes several passages from the book and presents commentaries.
From the Paper
"Men did pervert the religion of Christianity during the feudal era, as many men have perverted Christianity throughout the ages. It is not the religion, itself, that is corrupt, rather those who often times are the leaders of Christianity. This can be said of any religion at any one given time. Since Marsh did not specify which religion he found more charitable than Christianity, we don't have any basis for comparison. Marsh's statement is ambiguous and inconclusive and it detracts from the intent of his work."

Abstract
In March 24, 1989, Captain Joe Hazelwood and his crew impaled the oil tanker Exxon-Valdez on Bligh Reef, spilling more than 42 million liters of oil into the waters of Alaska's Prince William Sound. This paper shows that it was the worst environmental disaster ever to happen in American waters. The spill area was about the size of three football fields and covered nearly 1,400 shoreline miles of the Sound. The paper examines the immediate and long-term effects on the environment as a result of this spill. It also discusses the role of the media in the disaster.
From the Paper
"Immediately after the spill, nearly 800 birds were captured and laundered by scientists, but after their re-release into the environment, most birds only survived an average of one week before dying. Sea birds often gather at the places of land-water and air-water interface - the areas most disrupted by the spill itself. In the long term, however, the lowering of sea bird populations was related to their reproduction cycles, which were inhibited by the presence of oil in their nesting areas."

The Ecotourism Debate, 2005.
This paper discusses, switching from logging and fishing to eco-tourism, the economy of two towns, Ucluelet and Tofino, located between the Pacific Rim National Park on the western Vancouver Island, Canada.

Abstract
This paper explains that Tofino has already switched to an economy based on eco-tourism and is now overwhelmed with tourists and environmental activists; Ucluelet is still debating ecotourism and is facing major economic problems. The author points out that people working in tourist-based businesses are optimistic that the community will be well-served by an influx of eco-tourists; however, loggers and fishermen, who would be displaced, feel that tourism is low-paying, seasonal at best and unpredictable. The paper relates that the Ucluelet Chamber of Commerce and the Ucluelet Economic Development Corporation have developed a Smart Growth policy outlining a sustainable economy, which includes positions such as (1) undertaking development in a compact fashion, (2) supporting mixed use development, (3) protecting sensitive environmental areas and (4) integrating open space into daily living.
From the Paper
"In both towns, the supply and affordability of housing is now a problem for those who are seasonally employed--many of whom live in the area all year--and for those who are employed year round, but have middle or lower incomes. Seasonal visitors will pay premium rates for rental units. The result in Tofino has been a lack of affordable year-round housing. In Ucluelet such pressures have not yet become as critical, but as it also grows, it may face housing problems similar to those experienced in Tofino. Affordable housing is seen in both communities as an important part of sustaining the community."

Self-Shading, 2006.
A paper discussing factors that lead to self-shading during the development of leaf canopies.
1,010 words (approx. 4.0 pages), 13 sources, APA, $ 35.95

Abstract
This paper discusses the problem of self-shading that takes place during the development of leaf canopies, the factors that lead to self-shading and the importance of avoiding self-shading for the healthy growth and development of the canopy.
From the Paper
"Leaves are the main photosynthetic organ of higher plants. self- shading is not a problem, for example in plants exposed to very bright sunlight or having long narrow leaves, petioles may be missing. Large, thin leaves offer the maximum surface area to intercept sunlight for photosynthesis, but are highly susceptible to wind hurt and are likely to exhibit high transpiration rates. In addition, large thin leaves may less effectively capture CO2 than smaller leaves. Air moves more smoothly over large surfaces than over smaller ones, leaving a thin layer of non-moving air at the surface of a large leaf."

Global Warming and Sea Level Rise
Conclusion: Zero Emissions?
From the Paper
"According to A Primer on Global Warming, life on earth is dependent on the so-called "greenhouse effect," which keeps the planet about 59 degrees F warmer than it would otherwise be. It was the French mathematician and physicist Jean Fourier who first described in 1827 how Earth's thin atmospheric blanket warms the earth. The atmosphere, Fourier suggested, possesses special greenhouse-like properties that permit solar energy to enter and strike the earth as visible light, but which then impeded the energy's return into space as infrared heat. These "properties" are in fact the so-called greenhouse gases, which permit solar energy as visible light to pass through the atmosphere, but which absorb and re-radiate a portion of the same energy as it leaves Earth's surface as infrared heat. The net effect is a warming of the atmosphere. The relative warmth of a cloudy versus a cloud-free night sky is an accentuated example of this effect, since the water vapor making up clouds is itself a greenhouse gas."

Abstract
This essay presents opposing arguments to those presented in Mark Sagoff's article, "Zuckerman's Dilemma: A Plea for Environmental Ethics," in which Sagoff analyzes the concept of value and discusses the kinds of value that objects of environmental concern can have. The author of of this paper takes the position, instead, that man is designed to have dominion over the animals and fields.
From the Paper
"Sagoff uses examples of things in nature which society wishes to preserve for various values. For example, he discusses obvious instrumental grounds, like potential medicinal reasons for preservation. He then contrasts that society may wish to preserve a ten thousand-year-old forest for its aesthetic qualities. Clearly, the very definition of aesthetics is the appreciation of beauty! If man appreciates the beauty of an object, it serves him! Lastly, Sagoff talks of moral value of objects in nature. Yes, we must preserve resources, but only for the sake of preserving human resources, not to preserve nature for its own sake, or for its value to non human beings."

Abstract
This paper explains that the bull shark is the most dangerous form of shark known to humans. It examines the physical characteristics of this shark and then looks at its food habits and living habitat. The way it reproduces is also discussed and a look at whether the species is endangered or not.
From the Paper
"Growing anywhere from 7 to 11 feet long and weighing up to 500 pounds, the Bull Shark has no distinguishing markings. However, a short snout that is wider than it is long, small eyes, an off-white underside, and gray topside can identify it. The first dorsal fin of the Bull Shark is much longer and pointed than the second. As an adult, it possesses no fin markings, but may in some cases have a pale stripe along its flank. Also, the Bull Shark lacks a skin ridge between the two dorsal fins, which most other shark species possess."

Abstract
This paper attempts to compare Latin America to sub-Saharan Africa by incorporating the findings of three articles that look at immigration, environmental concerns and family planning. It aims to discuss how these areas of concern are being addressed and how they have been or may be solved.
From the Paper
"A major concern in Sub - Saharan Africa and the Latin American nations is family planning & sexually transmitted diseases such as HIV and Aids. "The ideal family size of about four children is lower in Rwanda than in most countries of sub-Saharan Africa. However, the annual rate of change observed between the periods of 0-3 and 4-7 years preceding the surveys (-4.2 percent) is clearly greater than those noted in the first phase of the fertility transition in Botswana, Kenya, and Zimbabwe."(Pillet) The use of contraceptives in Africa has declined as the use of contraceptives increases. The changes can be compared to Latin America in the 1970's. "In Asia and Latin America, the accelerated decline in fertility observed in a few countries in the 1950s and 1960s was repeated in most of the others in the 1970s." (Pillet)"

Abstract
Global warming is an ecological issue that is a contentious cause for alarm and concern in the world today. This paper attempts to establish the central causes and effects of global warming and the way it impacts on the environment as well as human health and society in general.
Content
1. Introduction
2. Definition and Overview
3. Causes
4. The Effects of Global Warming
5. Conclusion
6. Bibliography
7. Appendix
From the Paper
"Scientists and environmentalists as well as medical experts are becoming increasingly concerned about the varied effects of global warming over the past few decades. This sense of alarm is being increased by the fact that hypothetical predictions made about the probable effects of extreme weather and climatic changes, previously believed to be an indication of global warming, are in reality occurring worldwide. These events have also incited scientists to forecast even more extreme effects of global warming for the future. Experts are predicting that the survival of millions of people around the world are at risk from the effects of global warning including shortages of food supplies, the increase in infectious diseases and changes in the various biological ecosystems of the world, which are already having profound effects on human life and health."

Abstract
This paper describes the causes of the global warming phenomenon that have been a part of earth's geological history since the dawn of geological time. The paper also looks at the effects that global warming has on the earth and in particular its effects in the Arctic Circle.
From the Paper
"Climate change in general, and global warming in specific, are by no means new phenomena. Since the dawn of geological time, surface and atmospheric temperatures on Earth have fluctuated enormously. In some cases, worldwide climate change has led to actual shifts in land masses, leading to changes in the ways human beings and societies evolved. For example, global climate change caused the so-called Ice Age: "During the Quaternary period (the past million years) the ice cap has repeatedly spread to middle latitudes over the sea, with corresponding glaciation on the continents," (Gribbin Forecasts 73). The disappearance of the dinosaurs and other prehistoric creatures may in fact be due to climatic changes. Global warming has also been intense in our geological history: between ice ages, it is possible that no portion of the earth was covered with glaciation whatsoever (Gribbin Forecasts 73). Moreover, such massive temperature and climate transformations probably did not occur as a result of human intervention, but rather were a result of complex environmental, meteorological, and astronomical influences. Climatic fluctuations are indeed natural and inevitable."

Wood vs. Plastic, 2004.
An analysis and comparison of the use and production of wood and plastic.
742 words (approx. 3.0 pages), 5 sources, MLA, $ 26.95
»

Abstract
This paper discusses the use of wood and plastic. The paper outlines the history of both materials and examines the current usage of wood and plastic in today's world. Additionally, the paper presents the advantages and disadvantages for each material, in terms of price comparisons, means of production, the ability to recycle products made from the material and ease of use.
From the Paper
"According to researchers at the University of Madrid, recent discoveries of old stone tools in Penini, Madrid, which bore traces of acacia wood on their blades, show humans utilizing wood as far back as 1.5 million years ago. Previous estimates showed wood use beginning only 500,000 years ago near Germany and England, with the oldest wood implement being a set of spruce spears, dated 400,000 years ago (Schuster, 36). On the other hand, plastics are a relatively new substance, coming into existence in the late 1850's. Alexander Parkes, a British inventor, is discussed as the inventor of plastics with his creation of the first semi-synthetic material, cellulose nitrate. Following many financial hardships and material failure, Parkes exhibited the world's first plastics at the world fair in 1862."

Modern Utopia, 2006.
A paper describing the author's notion of a modern utopia.
1,173 words (approx. 4.7 pages), 3 sources, MLA, $ 40.95
»
Click here to show/hide summary
Abstract
This paper describes what the author believes would comprise a utopian society. In the paper, the author describes a utopian society as one that has a diverse population and attractive community features such as open-air spaces, parks, and recreational facilities, measures for controlling population density and sufficient job opportunities and transportation systems. The paper also suggests that a utopian society would also need broad and attractive architectural styles, nearby rural areas and be ecologically and environmentally friendly.
From the Paper
"Thomas More may have been one of the first people to envision a Utopian society in the 16th century. He wrote of a city that eliminated both poverty and exploitation based on employment for all (Porter, 2003), a radical concept at the time. More recently, the city of St. Louis, Missouri experimented with creating a Utopian-like residential community called "LaClede Town," named after one of the city founders. A large community of town houses, it was near the center of the city and encouraged an artistic, artsy atmosphere. A variety of talented people lived there, including Eddie Saxon (as a child), who went on to produce major movies such as "Philadelphia." Built in the sixties, residents were a mix of multiple races and income levels. The complex's racial mix was reflected in changes that took place in a local all-black church, that became integrated as white LaClede Town residents began attending (McGuire, 1995). However, LaClede Town was an island surrounded by declining areas. It addressed residential issues only, and ultimately failed and was razed (McGuire, 1995)."

Abstract
The American pattern of cities that spread further and further away from the center of the population -- urban sprawl -- can cause serious problems. This paper discusses some of the effects of urban sprawl such as the deterioration of the environment and the rise of poverty in the inner-city circle. The paper shows Washington D.C. as an example of urban sprawl.
From the Paper
"One result of urban-to-suburban population shift is that city populations have shrunk by more than 40%. In addition, those populations are over-represented by people who are poor, elderly, or criminal. These city populations tend to place strain on public services such as schools and hospitals even as the city's tax base shrinks from loss of both citizens and businesses."

Abstract
This paper begins with a historical review of how planet earth has been altered by the expansion of the human race, and the carelessness of that expansion. The paper then looks at the consequences of expansion by examining the specific problems associated with urban sprawl.
From the Paper
"Before humans began to build houses, roads, villages and cities, and in fact before there very few humans at all, trees covered "two-fifths (40%) of the land" on the planet (Victor, et al, 2000). That was eight thousand years ago. Humans have grown by great numbers since then however, and have cut forests in massive quantities for warmth, cooking food, growing crops, building ships and frame houses, and producing paper. Of the original forestland, axes, fires and saws have whittled away half, and "some analysts warn that within decades, the remaining natural forests will disappear altogether.""

Click here to show/hide summary
Abstract
This paper begins with a formal definition of global warming and then launches into a discussion of its primary causes and its effects. The paper concludes by briefly examining what measures can be taken to prevent global warming.
From the Paper
"There are many theories about the causes of global warming. The most well -known is the greenhouse effect. This theory states that global warming is caused mainly by the anthropogenic or human generated output of carbon dioxide. The theory also takes into account increases in temperature due to solar activity. ( ibid) In essence global warming "results primarily from human activities that release heat-trapping gases and particles into the air." (ibid) The most common causes of the increase in temperature are gas emissions due to the burning of fossil fuels such as coal, gas, and oil."
