Abstract This paper describes a chemistry experiment that examines the escape of CO2 from Seltzer water into distilled water, and from a solution containing NaCl into a solution containing CaCl2. The paper demonstrates that the escape of the gas was measured at 5-second intervals until the volume of gas did not increase.
Abstract The paper discusses the two alternatives of nuclear power and hybrid cars; both being economical enough to impact real change and be accepted into the energy spectrum. However, nuclear power has far more impact and has a proven track record. For example, the paper explains how nuclear power currently accounts for 20% of America's energy production and produces no carbon-dioxide. Hybrid cars, to this point, have only been able to reduce CO2 emissions by 50% and improve gas mileage by 2-3 mpg. This type of effect is simply on too small a scale to be economically viable or have an impact on the environment. The paper concludes that nuclear power, which is reemerging as a power source ready to expand, is the more viable option to reduce CO2 emissions.
From the Paper "For years alternative energy sources have been a major controversy. The debate has influenced many other areas besides simply energy consumption. It has clearly impacted the economic, political, and social climates of countries around the world. Nuclear power and hybrid cars are two alternatives that have been economical enough to impact real change and be accepted into our energy spectrum. Both of these alternatives are environmentally conscious and are helping to reduce carbon-dioxide levels in the atmosphere; however, clearly one is of greater use in the fight against CO2. Nuclear power has and will continue to be the major clean fuel source in the US, despite the positive impact of hybrid automobiles."
Abstract The writer of this paper analyzes the ongoing debates regarding the effects of fossil fuel emissions on the environment. This paper focuses on the role of the airline industry, which is a major contributor to this growing problem. This paper details the cause and effects of CO2 and NOx emissions, derived from the aviation industry and its resulting impact on the environment. This paper provides relevant insight into various aspects of the aviation industry, including the individual companies, aircraft manufacturers and ground support industries. This paper details the findings of the 2003 Rolls Royce environmental report, which stressed the need for immediate changes in the industry. The report emphasized the need to reduce fuel consumption and CO2 emissions. This paper discusses what measures have been taken by carriers and manufacturers to control emission levels and reduce pollution. This paper delves into the business practices of various companies, including JetBlue, which currently utilizes some of the most fuel efficient aircrafts available. This paper examines and details the new breakthrough technologies, that are proven successful in substantially reducing air pollution levels. This paper also contains an illustrative graph, citing toxic emission levels, relevant to this particular topic.

From the Paper "Another area for improvement in regard to fuel efficiency and reduced pollution in the aviation industry comes down to how carriers use airports for landing, loading and getting the plains back in the air. "Large airlines use a hub-and-spoke model in which flights are clustered around peak flying times at a few major airports. Low-cost carriers, such as Southwest Airlines, JetBlue Airways and AirTran Airways, do not use hub airports. Instead, they fly "point-to-point," which means they adjust their schedules and routes frequently to keep airplanes flying longer with the maximum number of passengers. The hub-and-spoke model is the most convenient for passengers, but the "point-to-point" system can bring in the most money on shorter routes. The hub and spoke model used by the major airlines for example has been the industry standard for many years because of the advantage of providing a broad geographic umbrella."
Abstract This paper explores the topic of carbon trading. The writer examines whether corporate carbon trading can effectively save the rainforest. Within that context, the author explores current environmental law and argues that they will lead to a demand on businesses to reduce or offset their CO2 emissions. The writer discusses the difficulty that many businesses will have complying with the law and restrictions. In addition, the environmental damage will increase which will in turn make for stricter laws. The final argument in this paper is that it will be more cost effective to save the rainforest as a CO2 offset than for the rainforest to be taken down for their wood use.

Making it a Corporate Issue
From the Paper "As the world continues to globalize, attention turns to the planet's rainforests and their future. Ecological groups have pitted themselves against large corporations for years regarding the forest and its value to the planet. Corporations are busily cutting down trees for commercial purposes while ecological groups are fighting to get it stopped because of the value the forests give the world by way of protection of wildlife. In recent years a new development has made the argument about conservation more valuable than ever. Carbon trading is a growing topic of debate when it comes to rainforest issues worldwide.
Providing the ability to carbon trade between nations and putting the responsibility of carbon trading on businesses world wide will alleviate future ecological issues currently being faced. Carbon trading is a more efficient and long lasting answer when it comes to the future of the rain forest. It has a longer and more deeply rooted value than wood cutting does because carbon trading does not involve the immediate destruction of wildlife and animal life."
Abstract The following paper examines the research provided on atmospheric depletion and its relationship to the survival of humanity. Issues like the greenhouse effect and ozone crisis are discussed. The writer feels strongly towards the serious danger from the pollution that is regularly released into the air and discusses, briefly, ways in which to halt the destructive process.
From the Paper "One way we are destroying our atmosphere is by releasing carbon dioxide gas. Carbon dioxide makes up part of a natural cycle of carbon involving the atmosphere, land, sea, and plant life (Neal 10). So what is the problem if CO2 is there naturally already? Carbon dioxide makes up a very tiny part of our atmosphere, representing approximately 0.035 percent (Neal 10). 0.035 percent seems insignificant, but consider that a rise of about 0.06 percent changes our atmosphere dramatically (Neal 10). Carbon dioxide is released into the air every time a fossil fuel is burned (Neal 11). Approximately two hundred years ago, the industrial revolution sparked an increase in the burning of the fuels (Neal 11). In fact, my grandparents reside in a small town in South Western Pennsylvania called Allison. This is one of a cluster of small towns in that region. I think that it is safe to say that about eighty percent of the homes in Allison rely on coal as the primary source of heat. Thank goodness for trees and other plants that takes in carbon dioxide and replaces it with oxygen. There lies another problem, though. See, there are not enough trees left on Earth to off set even a small increase in carbon dioxide because rain forests are rapidly disappearing."
Abstract The following paper examines how fossil fuels affect climate and contribute to global warming as well as the way in which acid rain and oil spills affect local wildlife. The writer also discusses the effects of mining waste, farming and pharmaceutical waste.
From the Paper "Fossil fuels have become a major factor in our lives, they are used to power cars, ships, aircraft's and entire economies but at an ecological price. From the combustion of fossil fuels is water and carbon dioxides. This the major waste gases. Others include nitrous oxides, carbon monoxides and sulphur oxides. These contribute vastly to global warming. When the sun radiates electromagnetic radiation through our atmosphere it hits the earth and then the earth reflect this back in the form of longer wavelengths as infra red radiation. "
A paper which discusses the issue of global warming and explores the reasons behind the argument that carbon dioxide emissions are most likely the cause of the global warming.
Abstract A paper which examines the arguments that refute that it is not accurate to mainly attribute the problem of global warming to the increasing carbon dioxide emission caused by human activities. The paper discusses the issue of global warming and explores the reasons behind the argument that carbon dioxide emissions are most likely the cause of the global warming. This paper provides the necessary information needed to support the argument presented, as well as discusses and analyzes the opposing arguments that are given in light of this controversial environmental issue. In the last part of the paper the author contends that despite opposing claims refuting the main argument, increased carbon dioxide emissions are still the primary reason why global warming has been prevalent over the years.
From the Paper "There are significant effects in the health of human beings and the environment due to global warming. Human health is threatened because too much heat in the atmosphere causes certain deadly diseases to propagate. Malaria is an example of this disease, which propagate under local climates (hot and humid climates). Excessive heat also result to respiratory ailments and death. Heat strokes attack many people especially when they encounter heat more than their body temperature can take or adapt to. Environmental elements such as water resources dry up due to excessive evaporation. Climate changes occur when excessive precipitation happens because of uncontrollable conditions in the atmosphere. Different landforms become barren and dry, making it impossible for plants to thrive. When this happens, animals that live in their habitats will leave, and may not survive. All of these effects in the environment contribute to the imbalance in ecological diversity."

From the Paper "In recent years, the number of individuals presenting with genital human papilloma virus (HPV) infection has increased. Typically, the infection is seen in the young; in particular, it often occurs in persons who have recently become coitally active. Ever since the association of HPV DNA with invasive carcinomas of the cervix, the infections have been the focus of considerable attention. However, despite abundant research into the characteristics of the papilloma virus and the nature of its infection, there still exists a lack of consensus regarding appropriate therapeutic modalities. Currently, a number of possible treatment options may be employed for HPV infection. The differences between these various modalities comprise both technical and procedural dimensions."
Abstract This paper begins by illustrating the process most commonly used to remove hydrogen sulfide from natural gas. The paper then goes on to describe an alternative method used for the removal of hydrogen sulfide and describes the benefits of this method, as well as some of the problems associated with it. Additionally, the paper points out that the water content of natural gas is an important engineering consideration concerning the sweetening process and presents an overview of the properties of pure acid gases and water and hydrogen sulfide. The paper then goes on to outline and explain additional processes and engineering considerations concerning the removal of hydrogen sulfide and includes some cost estimates and comparisons of the processes.

From the Paper "Sour natural gas contains hydrogen sulfide (H2S), which has to be removed to meet specifications for sales gas. Sour natural gas also contains carbon dioxide (CO2). The removal of CO2 and H2S, usually called acid gases, from sour natural gas is generally accomplished by means of a regenerative solvent. There are several amine solvents used for this purpose. Upon regeneration of the solvent, the acid gases are liberated, and are usually sent to a modified Claus plant, where the H2S is converted to elemental sulfur (Canjar & Manning 1967). The acid gas stream to the modified Claus plant consists of H2S, CO2, water vapor and minor amounts of hydrocarbon gas."
Abstract This paper defines homeostatis as the preservation of stability or constant condition in a biological system by means of automatic mechanisms that work against influences leaning towards disequilibrium. The author points out that, in human beings, many organs check homeostasis in the blood that gives fluid for all tissues; the kidney controls urea, pH and water concentration, the lungs control oxygen and carbon dioxide and the liver and the skin control temperature. The paper relates that homeostasis aids in discharge by eliminating injurious wastes from the organism: Lungs eliminate CO2 and water; blood vessels in the skin expand to let more heat to escape, sweat glands form sweat that pulls out heat from the body to evaporate it.
From the Paper "For the existence of a cell, homeostasis is necessary and each cell provides as part of body system to homeostasis. Homeostasis relies on the body's incessantly working of many actions. Its main activities or functions are reacting to variation in the body's environment, exchanging materials between the environment and cells, metabolizing foods, and incorporating all of the body's miscellaneous activities. Over the years, the capacity of the body to do many of its functions changes slowly. Generally, the body performs its duties perfectly at both ends of life - in infancy and old age. At childhood, body works effectively and efficiently. At late maturity and old age the reverse is true. Slowly they become less and less able and operational."
Abstract This paper looks at the Lewis dot structure, shape, and polarity of 16 different molecules. It then explains the difference in polarity between CO2 and SO2 based on their molecular shapes, describes the similarities between H30 and NH3 and notes what can and can't be told from a Lewis dot structure.
Abstract This paper answers some question on respiratory anatomy and physiology. It looks at lung function, how blood concentrations of CO2 affect blood pH, tidal volume, sensory receptors, and buffers.
From the Paper "When the diaphragm contracts it becomes flatter and drops and increases the volume of the thoracic cavity. The parietal and visceral layers of the pleura adhere to each other because of an attraction between the water molecules in the serous fluid between the two layers. This increases the volume of the thoracic cavity and causes the lungs to expand their volume. The intra-pleural pressure is less than the pressure within the lungs which also contributes to lung expansion. During labored breathing the external intercostal muscles and other muscles..."
Abstract The paper discusses a study undertaken as a collaborative effort by three different authors, that attempts to use the theory of gap dynamics to resolve the inconsistencies between the general belief that aspen stands are generally younger and uniform in age, versus available qualitative estimates that are consistent with much older forests. The paper examines how their conclusions and results raise a number of poignant issues, including environmental sustainability and CO2 emissions.
From the Paper "The long term success of any forest management program is dependent upon how accurate the data is. The trembling aspen (populus tremuloides) is an example of a tree commonly found in western boreal forests and is the main focus of this research paper. This study, undertaken as a collaborative effort by three different authors, attempts to use the theory of gap dynamics to resolve the inconsistencies between the general belief that aspen stands are generally younger and uniform in age, versus available qualitative estimates that are consistent with much older forests. The authors consistently argue that parts of Northern Alberta's boreal mixed wood forests are older than is generally thought, and is therefore being incorrectly managed."
Abstract This paper explains that, as a by-product of the industrial revolution, the natural equilibrium of earth is being altered by man-made conditions resulting in global warming or the heating up of the earth's surface. The author points out that the greenhouse effect is a natural phenomenon; however, the burning of fossil fuels has contributed to a huge increase in CO2, methane, nitrous oxide and other greenhouse gases in the atmosphere, which now trap more heat and thereby increase the temperature of earth more than usual. The paper relates that there is still a minority of scientists who are hesitant to accept the fact that global warming is a man-induced condition; nonetheless, their notions are silenced by the observed climatic facts that the eleven hottest years of the previous century occurred between 1983 and 2000 while 1991-95 are the five consecutive hottest years of the century.

Conclusion
From the Paper "At this rate of increase, the atmospheric CO2 concentrations are projected to increase the average global temperature by around 3 to 7 degrees F by the end of this century. This increase over a hundred-year period represents a huge shift compared against the entire time scale of the planet. Those who argue that global warming is a natural happening have to explain why nature would shift gears all of a sudden? Also, how could increased CO2 levels also be part of the claimed natural process? These questions and the true facts make it unambiguous that global warming is definitely a man-induced phenomenon. These arguments can be buttressed with the recently documented drastic climatic shifts."

Conclusion
From the Paper "The European market will not be able to achieve stability as long as there are no mechanisms in place to control supply and price. Many experts feel that the current situation means the end to low prices for consumers (Appert, 2005). The Brent price started at $40 a barrel in the beginning of 2005, but had risen to $70 a barrel after Hurricane Katrina took out many refineries along the Gulf Coast (Appert, 2005). Oil production has changed since the 1970s. During the 1970s companies worked on building a surplus. However, demand rose quicker than their ability to produce. Now companies work on a just-in-time basis (Appert, 2005). There is no reserve to level supply when it is needed. Changes due to shocks are seen rapidly on the consumer end. Consumers got used to stability in pricing during the 1970s. If supply was low companies had enough in reserve to meet the demand. "
