Acid Rain and Geology
Acid rain is a term that refers to a mixture of dry and wet deposited materials that falls in precipitation from the atmosphere, containing "higher then normal amounts of nitric and sulfuric acids" (Environmental Protection Agency). Some of the "precursors, or chemical forerunners" of acid rain are from natural sources like volcanoes and rotting vegetation; other precursors are from man-made sources like nitrogen oxides (NOX) and sulfur dioxide (SO2). The man-made emissions result for the most part from the burning of fossil fuels, like coal and oil for electrical production, according to the EPA.
et Deposition: In the United States, about two-thirds of all the SO2 and one-quarter of all the NOX results from the burning of coal and oil. Acid rain is created when these gases -- released through the smokestacks of the coal and oil-fired plants -- mix with water and oxygen and other…… [Read More]
Should Acid ain Be Made a Political Issue?
After studying several researches on how acid rain can cause economic losses, I chose a thesis proposal. I collected information from researches conducted in different countries and analyzed data using Microsoft Excel.
Acid rain is a problem that does not respect political barriers, thus, making it a global issue.
The world's population is currently around 7 billion and is still dramatically increasing. This increase is accompanied with an increase in land usage, deforestation and industrialization, contributing to environmental pollution. A major environmental hazard is sulphur dioxide. Urban areas are major contributors to this particularly harmful pollutant. It is released as a result of poorly controlled combustion, which maybe from factories, coal power plants or even from domestic use of sulphur containing fuel. Volcanoes are the natural cause of increased sulphur content in the environment. (Acid ain, 2011)
Sulphur dioxide and…… [Read More]
Materials and Methods
Because sulfur dioxide is converted into sulfuric acid, which bonds with water vapor in the atmosphere and results in acid rain, one of the best ways to look for the effects of that acid rain is to look to see how sulfuric acid directly affects specific items. That can be done by placing a few drops of sulfuric acid onto the selected items and waiting a few days to see what the results are. Being careful is key, because sulfuric acid is very dangerous. A well-ventilated hood and protective gloves should be used.
The other materials needed for this experiment are:
100 ml sulfuric acid (H2SO4), concentrated
Large Petri dishes with covers nylon stocking aluminum foil leaf, a flower petal, and a stick
The leaf, the stick, and the flower petal all had the same result. They were all darkened and shriveled a few days after…… [Read More]
It was discovered that a nearby factory was releasing sulfur dioxide into the atmosphere. The resulting acid rain had deposited on the surface of the marble (CaCO3) converting it into the dull gypsum (CaSO4.1/2 H2O). Calcium sulfate also has twice the molar volume of calcium carbonate. (Lambert, 1997) This expansion had resulted in added stress resulting in cracks. The relevant chemical reaction is:
CaCO3 + H2SO4
CaSO4 + H2CO3
Many such instances can be cited as the effects of acid rain. Acidity in rain results in greater incidences of rust. This is because the acidity results in the formation of ferrous ions, which in the presence of water results in Ferric Hydroxide, which is rust.
Fe(s) + 2O2(g) + 8 H+ (aq)
Fe2+ (aq) + 4H2O (l)

Despite some research, there is no direct evidence on the…… [Read More]
Acid Rain Be Made a Political Issue?
Acid rain spares nothing. Its effects are vast. It affects plants by destroying its roots, causing stunting or even death. Increased acidity in the soil, resulting from acidic rain, causes destruction of its nutrients which dissolve or decay in the acidic medium. Saprophytic microorganisms present are also destroyed. Acid rain falling on leaves dissolves its waxy layer. Damage to this layer makes the plant more prone to diseases and vulnerable to the effects of drying. Germination of seeds and reproduction are also inhibited. Eventually, the plants become weak and are unable to stand adverse climate, such as strong winds and rain. Ultimately, there is wide spread deforestation. ("Effects of Acid," 2007)
(Environmental Statistics, 2007)
The effects of acid rain, causing deforestation, have been observed in many places. Examples include eastside of Penn's state in Norway, trees in Scandinavia, southeastern Canada and northeastern United…… [Read More]
From the point-of-view of the variation and flexibility of the species such cultivated woody crops rank as no more than cornfields. While the tree farms are conveniently be stretched on the private lands, national forests those are considered priceless reservoirs of most of the biological diversity of the nation cannot expand so easily. The commercial logging is considered as the greatest danger for survival of the national forest system. The timber sales are growingly concealed beneath the post fire recovery and fire prevention missions, forest health initiatives and restoration programs. (Endangered Forests: Endangered Freedoms)
Declining wetlands and reservoir construction are having spectacular influences on a global scale.

living things are characterized by the following seven characteristics namely mobility, respiration, excretion, sensitivity or response to external stimulus, growth, feeding, and reproduction. Though there may be variations between animal and plant kingdom (ex, plants take in carbon dioxide and prepare their own food), these characteristics are commonly observed among all living things.
iology is a very broad field that encompasses the study of characteristics of living things. It includes botany, zoology and all other sub-disciplines that range from microbiology to evolution and ecology.
Evolution is the branch of biology that deals with the study of natural development of living organisms and the changes in them over time. Evolution refers to the heritable changes that occur in a population over a period of time. All the diversity that is observed currently in plant and animal kingdom can be ascribed to evolution over a long period of time.

It is therefore quite important to evaluate each experience on its own merits, as well as to how well each experience is integrated into the overall picture. An evaluation form has been developed for each participant as well as the parents of that participant. The evaluation form will be handed out at the end of each of the camps (whether the attendee stayed for a one-week or the full three-week course will be noted) for completion and return to the directors of the camp.
After the evaluation forms have been returned, the responses contained therein will be analyzed and broken down into categories pertaining to each camp experience and how it (they) were perceived by the campers. Follow-up questionnaires can be sent to each participant on a bi-yearly basis in order to gauge what type of long-term effects the camps continue to have on the participants.
The project is proposed…… [Read More]
Toulmin Model argument in response to one of the following prompts:
• What specific action(s) should Christians take regarding the environment and its preservation or restoration?
Active in 15 countries, "Target Earth" is a group of individuals, churches, college fellowship and various ministries that are Christian protectors for everything that God created. The group feeds the hungry, saves endangered animals, rebuilds forests, and serves as active voice for environmental concerns. The groups mission is "erving the Earth, erving the Poor," which defines their connection of Christianity to environmentalism as they see it (Target Earth.com).
The news media is full of warnings that deal with environmental issues of one kind or the other be it global warming, endangered species, extinction of the rain forest, pollution, nuclear accidents, and so forth. The Christian community seems to apply less attention to these issues than they do to others. It may be because we…… [Read More]
Social Ecology of Health Promotion
Module 05 Question 01: explain the rationale behind the federal government's approach to regulatory containments in food.
The federal government's approach in relation to the regulation of the containments in food, aims at protecting the consumers on food insecurity through elimination of food pathogens. It is the role of the government to enhance the health system and conditions of its citizens through adoption and implementation of various rules and regulations in relation to the containments in food. The food supply of the United States integrates multi-faceted production system and delivery components. Some of the critical or essential components of this system include production, processing, preparing, packaging, labelling, distribution, and consumption of the food components (Fortin, 2011).
There is a risk in relation to the concept of each stage of the food supply system in the context of the United States. This makes it ideal for…… [Read More]
heavily-increasing industrialized world, sulfur oxide emissions and other oxidizing gases have become problematic within the planet's atmosphere. These emissions cause acid rain, which has become detrimental to both the atmosphere and the Earth's environment over the years. While there have been numerous instances in which the United States and Europe have attempted to curb industrial emissions of sulfur oxides and nitrogen dioxides, the environment's return to a less acidic pH will take longer than expected. Acid precipitation has hit the lakes and streams the hardest, and even with the decrease of emissions, the acidity of said lakes and streams, for the most part, have remained the same.
Cause of Acid Rain
Acid rain, or "acid precipitation" as most scientists call it, is the "common name for [a] form of air pollution," which harms the environment ("Acid Rain"). This phenomenon is usually caused by a displacement of pollutants into the atmosphere,…… [Read More]
At the time, the industry sought to examine both oil pollution in general and ocean dumping as well as land-based sources of ocean pollution. According to ang, "More significant was the rapid technological development in the design of large-sized oil tankers which required constant rule changes. By 1973 it was evident that the 1954 convention provisions were inadequate or outdated, and by then the likelihood of the 1954 convention coming into force was rather doubtful" (334).
The new protocol ultimately entered into force in January 1978. The 1973 version of MARPOL was comprised of 20 articles concerning general obligations under the convention (e.g., prohibition of violation of requirements, rules for ship inspection, enforcement, reporting on incidents involving harmful substances, and most importantly, five technical annexes or regulations on 1) oil pollution; 2) control of noxious liquid substances in bulk; 3) harmful substances carried by sea in package forms or in…… [Read More]
US Government and Environmental Ethics
The United States government has had a long history with the environment, beginning with the very beginning of the settlement of the Pilgrims, through the industrialization era, forming the beginning principles of having national parks, and to today with the onset of climate change and the environmental hazards of the 21st century. (National Park Service, 2012) Compared to other countries, the U.S. has had a more favorable view towards the use of the environment for business matters, often leaving entire communities scarred by the unprotected use of machinery and pollution to retrieve coal minerals, build six lane highways through forests, and even building massive subdivisions of buildings so close together that they represent risks of fire and natural disaster. There are several government agencies that have been created through the years to govern the vast territories that have been preserved, but the amount…… [Read More]
" And following that experience the class can discuss what acid rain does to the ecosystem and the teacher can show a video of a forest devastated by acid rain, or just photos of depleted forests and dead fish floating on a stream or lake (waters that have been polluted by acid rain).
About this time, students are asked: "here does the acid rain come from?" Let them guess, and talk about it. Then the teacher shows photos of smokestacks belching out clouds of brown sooty looking pollution and explain that once in the atmosphere, the pollutants (they don't need to know the science of precisely what chemicals bond with condensation but they could certainly relate to dirty polluted particles joining with raindrops) return to earth as acid rain. And as an additional part of this curriculum, students should be shown the various products that are produced in the factories…… [Read More]
Some forms of energy, such as wave and tidal energy and hydrogen fuel cells are still being studied. Another writer states, "Techniques to harness the energy found in the oceans are best developed for tidal power, wave power and ocean thermal energy conversion" (Middleton 52). Many other types of alternative energy, such as solar, wind, biomass, and geothermal energies are all being used where they make sense. Other solutions include nuclear energy, but the problem of disposing of the nuclear waste is a big problem, and so, no new nuclear facilities are being built. Authors Ottinger and Williams continue "Nuclear energy is excluded [...] because of its high capital and operating costs, complex technical requirements for operation and maintenance, and unresolved problems of proliferation and waste disposal" (Ottinger and Williams 331).
None of these solutions are being used enough to remedy the problem, and there are many reasons why they…… [Read More]

Emissions from a new car purchased today are 90% less polluting than a new vehicle purchased in 1970. The Act has been reformed to include a provision that in 2004, all new passenger vehicles, including SUVs, minivans, vans and pick-up trucks, must meet even more stringent tailpipe emission standards. "This marks the first time that light-duty trucks, including SUVs, pickups, and minivans are subject to the same national pollution standards as cars." A common criticism of the Act was that because it had different standards for larger vehicles, a critical component of vehicle-related pollution was being ignored.
One of EPA's earliest accomplishments was the elimination of lead from gasoline. The use of lead-based gasoline had effects beyond that of air quality. "Elevated levels of lead can damage organs and the brain and nervous system, and affect the heart and blood. Adverse health effects range from behavior disorders and anemia…… [Read More]
Many limestone statues and building surfaces have suffered severe damage due to acid rain. Acid-based cleaning chemicals can also etch the limestone. Limestone should only be cleaned with a neutral or a mild alkaline-based cleaner.
Limestone is also used as a frontage on skyscrapers as a thin pate for covering the solid blocks. Limestone is also used in products such as quicklime and slated lime. It sis used for cement and mortar. Limestone can be pulverized and used as a soil conditioner to offset acid soil conditions. Limestone is also crushed and used as a base for roads. Amazingly enough limestone is also used for glass making.
As limestone is valuable natural resources, it is used to make things that we all require, such as concrete and glasses. Limestone was as well admired for building block in the middle ages. Many medieval churches and few other castles in Europe were…… [Read More]
Alberta province of Canada is considered one of the strongest economies in North America, being culturally diverse as well as politically and environmentally stable. Its varied landscape, sunny climate and varied geography make it a most ideal locality and provide its people an excellent quality of life. Alberta is endowed with abundant natural resources, natural sceneries, and capable manpower that altogether make it the perfect place to live and work in. These outstanding features are collectively referred to as the Alberta advantage (Government of Alberta 2002). Its people are vibrant, resourceful and productive entrepreneurs, whose goods and services rank among the most excellent in the world. This level of excellence draws from the inherent pioneering spirit of the earliest settlers of the province. The present principal industries of the province are agriculture and related industries, forestry, telecommunications, oil and gas. Its oil and gas industry, which began in the late…… [Read More]

Climate Change - Carbon Emissions
Climate change poses one of the most difficult questions to the world today. Cities continue to be the main contributors of this challenge. Most of the greenhouse gases are produced by industries, motorized conveyance, domestic fuel, and disposal of waste and are centered in and around cities. The IEA (International Energy Agency) foresees almost three fourths of the carbon emissions coming from urban centers by 2030. It then becomes imperative for the cities to take cognizance of the fact and react to lessen the effect. Creating an inventory of the carbon footprint would then be the logical first step in the process of addressing the issue of climate change effectively. In…… [Read More]
) Hydrochloric acid, formic acid, nitric acid, hexanes, and toluene are all available in ACS grade through Carolina, which, with a bit of imagination, could turn into some spectacular experiments. (Toluene is, of course, a component in the production of TNT -- talk about an exothermic reaction.)
Laboratory equipment is also widely available. A simple search of the popular site Shopwiki.com reveals hundreds of beakers, pipettes, test tubes, alcohol burners, syringes, etc. More advanced items are also available, such as hot plates which automatically stir the contents of a flask placed on them, and a wealth of thermodynamic devices for pressure, temperature, and volume control.

The Leblanc alkali production processes were especially pernicious, but they followed along the lines of previous industrial processes. In other words, the first British environmental legislation was a response not so much to a qualitative change in industrial processes and their environmental impact but more to a quantitative increase in sources of pollution that had up to that point been (if only barely) tolerable.
Legislation Arising From Public Anger
At the center of the first British environmental legislation was the Leblanc process, an industrial process that produced of soda ash (which is chemically sodium carbonate) that came into use in the first decades of the 19th century. Named after its inventor, Nicolas Leblanc, it replaced an older process in which soda ash had been produced from wood ash. However, as the availability of wood ash declined (because of deforestation, a process that was occuring both in Great Britain and across…… [Read More]

The Great Lakes also contain large amounts of 'polychlorinated dibenzo-furans - PCDFs' and 'polychlorinated dibenzo-dioxins -PCDDs' which are a result of the chlorine bleaching process of paper and pulp mills. In a nation wide study conducted for a period of 4 years on samples of fish and shellfish from various freshwater and marine water bodies in Canada, it was found that the fish from the Great Lakes were among the most contaminated samples. (Steinhart; Doyle; Food esearch Institute, Cochrane, 1995) the paper and pulp industry has also grown with the growth of the economy. However, contaminant discharge from this industry still continues despite the various environmental measures taken by the paper and pulp industry of Canada. This industry has also caused disturbance to the huge boreal landscape of Canada. Approximately 50% of Canada's fresh water is located in these boreal forests. Developmental activities have affected these…… [Read More]
The 1980s (the period when onald eagan was the U.S. President) witnessed a series of government measures targeting environmental regulations. This resulted in public outrage against the anti-environmental policies of the government leading to a renewed interest in nature clubs and groups and the formation of radical groups who led strong movements to protect the environment. (vii) the post- eagan resurgence (1990s onwards) - President Bush and President Clinton did not take the radical stance of their predecessor. However, President George W. Bush has taken many measures which have weakened the environmental movement instead of strengthening it. This includes opposing curbs on greenhouse emissions via the Kyoto Protocol, supporting oil drilling in the ANW or Arctic National Wildlife ange, weakening clean air standards and lifting the ban on logging in forests.

EPA established that exposure to indoor NO below the 53 ppb outdoor standard could lead to respiratory symptoms among children with asthma, especially in a multi-family setting (elanger 2006). This effect continues to be a public health issue because of the number of people exposed to the gas. According to the U.S. Census, more than half of all U.S. households use gas. Their primary source of residential NO is a gas-fueled cooking appliance. This was the summary finding of a study conducted with 1,002 participating families in Connecticut and southwestern Massachusetts from 1997 to 1999. It associated indoor NO with increased respiratory symptoms among asthmatic children. At present, there are no U.S. standards for indoor…… [Read More]

An Analysis of the Implications of Technology and the Global Ecosystem
The 21st century promises to usher in innovations in technology that cannot yet be imagined, and the advancements to date have provided many in the world with unprecedented standards of living. Improved methods of transportation and communication, combined with more leisure time than ever in which to spend it has resulted in many people developing a keen appreciation for technology and what it promises for mankind; an unfortunate concomitant of these innovations in many parts of the world, though, has been an intensive assault on the globe's ecosystem in an effort to bring emerging nations into line with the productivity being experienced in the developed nations of the world. As a result, a debate over whether or not technology threatens the integrity of the global ecosystem has emerged in recent years, and pundits warn that…… [Read More]
History Of Climate Change and Potential Impact of Climate Change
HISTOY AND POTENTIAL IMPACT OF CLIMATE CHANGE
History of Climate Change
Climate change can be traced back to the 19th century when ice ages together with different natural changes were first noted, and effect of greenhouse first identified. Most recently, the glaciers are melting. Water levels in the seas are increasing. Evidence of increased temperatures in the atmosphere is evident from these. For the last ten years, rampant cases of tornados, winter freezes, wildfires, tropical cyclones, and floods have been common in the US and across the globe. Besides, environmental temperatures have risen steadily over the past century. Today, human activities have advanced, with their eventual effects resting on the environment (McNall, 2012). The use of nuclear energy is a devastating blow to the sustenance of the natural state of the cosmos. The use of fossil fuels has increased the…… [Read More]
The state has really took out half of the $300 million cost that it took to build the Hudson River Park (150 acres land/400 acres open water) with yearly assumptions that are around $20 million to $25 million. 20 years from now it might be a hard challenge keeping this up with the anticipated climate change.
Climate Change: Precipitation
The third reason why climate change will be affecting America in the next 20 years is because of the local precipitation. In addition to impacts on temperature and wind, the urban heat island affects local precipitation patterns. Both comparatively warmer air and higher attentions of particulates over the cities that can cause little more frequent rain events (Ahrens 2006).
About 20 years from now, this will become an issue because the Human-made modifications of the natural environment are affecting the thermal stratification of the atmosphere that is located above a city…… [Read More]
Deposition occurred over a very long time period. The study found that the sediments separating the two events were characteristic of normal sedimentation, with burrows formed by creatures colonizing the ocean floor, erosion and transportation of sediments, and no evidence of structural disturbance" which means that there is no reason to believe that the asteroid impacted normal life in measurable fashion very quickly, or that fossil evidence of the asteroid's impact had been disrupted (New blow against dinosaur-killing asteroid theory, geologists find, 2009, National Science Foundation).
Even defenders of the asteroid theory think it is unlikely that it was a one-time event that killed most of the life on planet earth, and believe that the asteroids created inhospitable conditions that developed over time. Recent research also indicates that the asteroid "landed in deeper water than previously assumed and therefore released about 6.5 times more water vapor into the atmosphere. The…… [Read More]
(Jordans, 2008) "Europe's unilateral approach will only lead to legal battles and trade wars," Bisignani also stressed. (Jordans, 2008) a hint of this contention occurring in the future was evidenced recently when 27 nations, including the U.S., China and 25 other countries, registered opposition to the EU's attempt to include commercial airlines in its cap-and-trade program by supporting an ICAO-run program. This signal confirmed united opposition to the European Union's intentions to develop a separate, regional emissions trading system. U.S. officials warn that the inclusion of U.S. And other non-European airlines in the EU cap-and-trade program "may break international aviation and trade laws." (Jordans, 2008) Although reasons differ, along with official warnings, scientists raise questions regarding the European program. Airlines, experts basically agree, contribute approximately 2% of man-made emissions of carbon dioxide, a gas reportedly contributing to global warming. Perceptions, nevertheless, differ regarding the impact of other gases aircraft emit,…… [Read More]
" (2007) Recommendations of this report include those as follows:
China should learn from the successes and failure of the U.S. And other developed countries in reducing the influence of energy use on air quality;
Continued dialogue and information exchange among U.S. And Chinese scientists and policy-makers should be promoted through professional organization, government support programs, and the National Academies in both countries to promote joint development of energy and pollution control strategies." (Committee on Energy Futures and Air Pollution in Urban China and the United State, Policy and Global Affairs, 2007)
Other findings of this report include the fact that "an important lesson learned is that air pollution damage imposes major economic costs, through premature mortality, increased sickness and lost productivity, as well as in decreased crops yields and economic impacts."

Although ecologism is rapidly developing into a political ideology in its own right, its widespread acceptance and influence continues to rely on its relationship with other, existing ideologies. One of the most important, and influential, of the 'isms' is Marxism, and the link between it and ecologism is increasingly becoming the subject of academic and political study. This is especially true within the field of environmental sociology, where the Marxist perspective's ability to address the issues of ecologism and sustainability is the root of growing debate and analysis.
Ecologism, which according to Andrew Dobson, "holds that a sustainable and fulfilling existence presupposes radical changes in our relationship with the non-human natural world, and in our mode of social and political life" (2), is a relatively new arrival to the field of environmental politics. Only a few decades ago, environmental and ecological issues, such as global warming, genetically…… [Read More]
Lightweight concrete maintains its large voids and not forming laitance layers or cement films when placed on the wall" (p. 1). As noted at the start of the report, "The Pantheon" in Rome, built more than 18 centuries ago depicts an explemaenary example of the durability of lightweight concrete.
In contemporary construction projects, sructural lightweight concrete proves to be in high because of its lower density. The use of smaller load bearing elements or cross sections results in the builder or designer being abile to construct a smaller foundation. In the journal article, "The effect of high temperature on compressive strength and splitting tensile strength of structural lightweight concrete containing fly ash," Harun Tanyildizi and Ahmet Coskun (2008), both with the Department of construction education, Firat University Elazig, Turkey, identify a number of advantages to using structural lightweight concrete . These include the project possessing increased strength and more flexibility,…… [Read More]
Fewer predators (i.e. fish) without simultaneous declines in reproduction would mean an increase in the number of insects in the area of acidification. This can increase the number of pests in the area, affecting crops. It could also lead to an increase in disease carrying insects, such as mosquitoes, leading to higher disease rates among other animals, including humans. This could affect populations of these other animals, affecting populations of other species that prey on or are preyed upon by these species, and so on.
Ecosystems are incredibly complex things; the interconnections between the disparate elements are so intertwined and so complex that it is almost -- perhaps completely -- impossible to know the effects of changing or removing a single element. Even more complex and unknowable are the indirect effects on portions of an ecosystem from other sources. The acidification of the Hubbard Brook is almost certainly a result…… [Read More]
(A Mosel iesling, 2011)
The region in which German iesling grapes are grown is centered on the valleys of the Mosel iver, especially along two of the Mosel tributaries, the uwer and the Saar. These valleys are far from rolling: The valleys along the Mosel are steep, so much so that they might seem (if they were not already planted with vines) to seem too steep to support viticulture. These hillsides are also relatively steep, which is one of the most important elements in what makes German ieslings acquire their specific identity. The higher altitude at which the grapes are grown translates into a cooler microclimate for the grapes, which lengthens the period that it takes for the grapes to ripen. This is one of the fundamentals of German ieslings (Dawson & Molesworth, 2011).
The soil type in the Mosel Valley also affects the taste of the ieslings produced from…… [Read More]
I was born and raised in Taipei, Taiwan, which is very different than the United States in many ways. Although the country is becoming more advanced, some forms of its culture are still very traditional. Also, the standard of living is much lower than most of America.

A strictly vegetarian diet is best suited to the human body's needs, mankind's ability of survival on earth, and our inherent compassion. Switching to such a diet is fairly simple and creates the opportunity to lead a healthier, happier, and gentler life (Marcus, xi).
For numerous reasons, humanity has been increasingly taking to veganism since the last few years. Some vegan supporters assert their participation in a dietary regimen wherein consuming or utilizing animal products is unethical, according to their religious beliefs or values. Meanwhile, others put forward the argument of animal consciousness's ethicality and the industrial farming process. Those who claim to be vegans most probably do so owing to environmental, animal rights, or personal health concerns, which can alter with time. Several vegans begin as vegetarians, gradually ceasing consumption of milk, eggs and other animal by-products. Meanwhile, others turn purely vegan right from the outset. In…… [Read More]

As to the climate, as a result of huge factory smokestacks belching out black smoke from the burning of coal, the atmosphere slowly began to change and severely affected rainfall patterns and created variations in the temperature of the air. This was the beginning of what we now call acid rain, a combination of water and carbon dioxide which slowly pollutes everything it comes in contact with, such as aboveground water sources (lakes, rivers and wells) and even the land itself in the form of run-off which eventually ends up in agricultural areas where food is grown and harvested.
With earth's landforms, the excavation and removal of coal in such places as England and the Eastern United States greatly devastated the natural landscape by leaving behind immense sections of land stripped bare and left wide open to further erosion by rain and wind. Since iron ore, copper and tin were…… [Read More]
7 times as dense as lead, and when the shell hits the target, it burns and releases uranium oxide into the air (Eco pp). "The poisonous and radioactive uranium is most dangerous when inhaled into the body, where it will release radiation during the life of the person who inhaled it" (Eco pp). According to Robert Fisk, "there is evidence that the depleted uranium residue left in Iraq is responsible for a large increase in stillbirths, children born with defects, childhood leukemia and other cancers in southern Iraq near Basra" (Eco pp). A study on the long-term effect of DU on the Iraqi environment found the presence of isotopes of U-238 series in over a third of the collected plant samples, with some wild plant samples possessing concentrations of radioactive elements up to three times the natural background (Impact pp).

Wicked Problem: oyal Dutch Shell and Its esponse to the Nigerian Oil Spill
Major oil companies such as oyal Dutch Shell are responsible for hundreds of oil spills every year that cumulatively involve millions of barrels of oil. The harmful effects of such oil spills on the environment is well documented of course, but less well documented are the different types and levels of responses that are used in response to oil spills in developing nations and those used in affluent nations. While oil spills such as British Petroleum's recent rupture of its Macondo well offshore United States are the focus of a massive and expensive coordinated response, far less attention is paid to oil spills that affect emerging nations such as Nigeria. This is not to say, of course, that all major oil companies -- including oyal Dutch Shell -- are completely abrogating their corporate responsibilities for oil spill…… [Read More]
Through research on the risks that come with uranium and coal for energy plants, there can be determination of which among the two is better for human sustainability.
Green house gases
Electricity plants that use coal for electricity production release large amounts of greenhouse gases and other pollutants that are harmful to the environment, bearing that coal is packed with high levels of hydrocarbons. Among these gases is sulfur dioxide that results in acid rain formation and consequent depletion of environment and even property that is reactive to sulfuric acid. Nitrogen oxides are also produced and together with VOCS result to smog formation. Mercury is also produced alongside Carbon dioxide which are direct contributors to negative climate change (Matthews, 2012).
On the other hand, in the nuclear power plants there is no production of gases such as nitrogen oxides, sulfur oxides, carbon dioxide, mercury or such other toxic gases. If…… [Read More]
8% as compared to the dollar in the start of the last year to January this year. The value of Yuan has improved even with the fall of other emerging economies. The loss of competitiveness that resulted can be best demonstrated by a ratio that has been calculated by the Hong Kong Monetary Authority, which makes a comparison of Yuan with the currency of the other emerging markets that are in competition with China. It is important to note here that the competitors of China are the countries that trade against it, and not necessarily the countries that trade with it. The index calculated by the authority demonstrates that Yuan has been rising over 13% in the year to January. As for January alone, the value of the Chinese currency has risen by 2.6%.
The authorities of China have not said that they had made a move in to weaken…… [Read More]
Sustainability More About Politics Than Science?
The environment is a word which refers to the natural effects around us including the atmosphere, seas and oceans, rocks and mountains, plants, ice formations, human beings, stars and several others. These effects are best left in their natural state because when they get disturbed, they could have serious consequences on the atmosphere, electricity, water, weather, fire and the earth's magnetism. Sadly, this is the situation of things now and these consequences are real. Several problems are facing the environment causing global adverse effects and putting the people in it at risk. This research studies these problems and determines if the scientific and political measures put in place are effective in mitigating them
Environmental issues facing the world
The disturbances in the environment have brought about noticeable changes in climate and high frequencies of natural disasters. Take for example; the problem of global warming…… [Read More]
Economic entities can be influenced by the area they are located in, with the entities positioned in the vicinity of economic blocks like NAFTA or the European Union being advantaged and thus more likely to engage in trade. People in North America and those in Western Europe are advantaged because of their position, meaning that the trade business they get involved in is normally more intense in comparison to the trade performed by economic entities that reside further away from economic blocks.
Security has always been a crucial matter when it came to freight transportation. However, this topic has not been given special attention until the 9/11 events, which marked the beginning of great changes in transportation policies. It previously seemed perfectly normal to check freights for illegal substances, undocumented immigrants, and piracy. Even with that, the World Trade Center events brought forward a new set of security concerns. The…… [Read More]
These types of trips accounted for 33% in 2004, a major increase since 2002, when they only accounted for 17% in all international trips. Finally, the third most common stimulus for trips abroad was that of visiting family and friends. In 2002, the rate of these trips was of 28%, but by 2004 it had declined to 22%.
Another trend obvious in the past recent years is that of Polish tourists visiting destinations considered untraditional so far. This is generally the result of intensified marketing efforts and the most relevant example in this sense is the still growing number of Polish individuals traveling to the African countries, namely Kenya. Also, the results are due to a long historical relationship between Poland and Kenya, basically the fact that Poland has offered scholarships to the Kenyan students and that they have also helped defend the British territories in Kenya against Germany, during…… [Read More]
Deforestation can also lead to soil erosion, and more silt in rivers, streams, and behind dams throughout the deforested area. Biological diversity, including many unique species and ecosystems are lost, as well.
IN order to stop deforestation, people must be more aware of the problem and stop using products made from wood, such as paper, cardboard, and other products. We also need to find alternatives for wood products, such as the recycling of paper and wood products, and building materials such as steel, and products like Trex, which is a non-wooden material used for outdoor decks and such. To stop deforestation, we have to stop cutting down trees. eplanting deforested areas does not help, because it takes too long for the trees to grow, and the damage cannot quickly be repaired.

However, there simply does not seem to be sufficient evidence for the disease hypothesis. First, there has been no evidence of disease found. Next, even extremely virulent diseases, like the plague or West Nile Virus, do not have the kill rates necessary to cause the extinction of an entire species. In addition, one has to realize that the extinction of large mammals coincided with the extinction of other animals, like birds, marsupials, placentals, testudines, and crocodilians. It is unlikely that a disease would be lethal in such a wide-variety of animal populations, especially when it did not destroy all species of certain animal genus.
The final theory is that a meteor killed the large mammals. There is evidence that meteor impacts caused earlier extinctions like the Permian-Triassic extinction and the extinction of the dinosaurs. Meteor impacts can interfere with food sources, because the resulting dust in the air interferes with…… [Read More]
Of course, the 2007 pet food scandal is also a result of this same lack of regulation and inspection in China. Pet food manufactured here in the United States and in Canada contained melamine, an ingredient used in the manufacture of plastic dinnerware, but also a key ingredient in many fertilizers. It sickened thousands of dogs and cats, and hundreds died as a result of eating the tainted pet food. This incident helped bring the dangers of Chinese imported food and other products into focus, and made it much more real for many Americans. As a result, many people are becoming more vigilant about Chinese products, and some Congressmen have called for bans on all Chinese foods that are not inspected, but that has not occurred.
Clearly, this poses a danger to American consumers, and it is one reason that Chinese imports are the biggest threat to America.
However, Chinese…… [Read More]
Such things, however, do not appear impossible given the state of science today.
There is one area of concern that science cannot totally resolve, unless it builds a time machine and can go into the future. That is, what are the total ramifications that result from science's wonders? Albert Einstein did not consider nuclear bombs when coming up with the equation of E=mc2
He considered himself a pacifist, yet encouraged the building of the bomb for fear that the Germans would create it first. He was looking toward the future. As he wrote to physicist Niels Bohr in December 1944, "When the war is over, then there will be in all countries a pursuit of secret war preparations with technological means, which will lead inevitably to preventative wars and to destruction even more terrible than the present destruction of life" (Clark, 2007, pg. 698). Then, close to death he stated:…… [Read More]
Some companies, perhaps sensing a business opportunity, have tried to use the green textile movement to their advantage. DuPont and other chemical companies have targeted a potentially hopeful resource for the future in the form of enzymes, which can be very effective in fiber preparation, pre-treatment and value-added finishing as catalysts. Because enzymes work "even under mild conditions and do not require the high energy input often associated with chemical processes," they offer a more ecologically friendly way to treat fabrics than harsh formaldehyde or chlorine ("Textiles and leather," Industrial Sustainability, 2007).
It may sound paradoxical that enzymatic chemicals can make the industry more sustainable. Another paradox of the industry is that natural fibers such as cotton and hemp may not be as eco-friendly as one might expect. For example, in the United States, about a third of a pound of synthetic fertilizers and pesticides are required for the process…… [Read More]
Firstly, it is crucial to raise awareness and to actually make people listen, care and then act accordingly. verybody needs to understand that the environment should be everyone's concern because it truly affects all of us as we are all inhabitants of the same planet. This is achieved through information which in turn, is achieved through long-term campaigns which have the mission to reach as many people as possible. This is where the civil society needs to really step in and help improve the quality of information as not everything we hear or see on television is actually scientific information. In fact, spreading untrue or simply unscientific information can be very harmful to society and its attitude towards the environment because people do not know what to believe. On the other hand, there is the danger of over exposing a certain topic, in this case environmental issues, which leads to…… [Read More]
Repatriation of profits have proven to be a problem as well. Fourth, as stated by Staff (2004) is the challenge presented by poor training in the sector which is stated to be "...weak both at a practical level as well as at a higher strategic level" and the problem has only been exaggerated due to the government and other regulatory authorities in China to promote logistics programs." (Staff, 2004) the fifth challenge stated is in relation to "information and communications technology" in China characterized by a: "...lack of it standards and poor systems integration and equipment. At a very basic level, the consistent supply of energy is also problematic leading to interruptions to communications through power outage." (Staff, 2004) Sixth presenting in the way of a challenge is the "undeveloped domestic industry" due to fragmentation of the logistics sector in China that is: "...dominated by commoditized and low quality transport…… [Read More]
Whether it is solar power, used vegetable oil, turds, wood, or hydrogen research and experimentation is the way forward. These cheap resources have already been proven effective in various ways and manners. The need of the day is to develop new energy technologies and apply them in the most useful and practical way possible. If we want global economic stability then eco energy sector requires due attention. We have witnessed crises situations in the past. The rising demand for oil, its increasing prices and possible depletion of oil resources demand a way out. Alternative energy sources in this scenario give us a flicker of hope. U.S. government is also pushing the agenda and so should other individuals and organizations also look in this direction for the economic betterment of their counties and the world with the use eco-fuels. The change cannot be brought about by government alone, will and…… [Read More]
e like to make believe in some kind of happy ending, even to an overwhelmingly gloomy story. Even the hero of Miller's The Dark Night Returns is hardly the hero that any of us would want to follow. Miller's Batman is an unapologetic reactionary who in the process of an interrogation of a prisoner, he threatened a man he had put in a neck brace and crutches and mocked him when he claimed, "I got rights (Miller 45)." The new Batman seems to be an even bigger reactionary than the person who trained him (ibid 199). The darkness of the Bat Cave brings the tale full circle as the heroes have become like what they are fighting, dark and corrupt without any inherent light. Only outside and artificial light illuminates imaginary Gotham of Miller's dark knight as it does the New York City of Spiegelman's mouse man as he sees…… [Read More]
law help protect the environment and what steps can citizens take to ensure that the law accomplishes this goal?
Protection of the environment is important for our health, but humans affect the system through various means such as through polluting water and atmosphere with toxic gasses, with oil, with car fuels, and with debris that is plunked into the waters as well as depleting the fisheries and filling the air with smog and the earth with pollution.
It is for this reason that legislation is put into effect to curb our destruction and to teach us how to look after the environment in better ways. The state employs its own regulations, but it needs a synthesis of both state, business and citizen involvement to safeguard the environment, and motivation from both business and citizen is not always forthcoming. The following essay discusses policies that have been implemented to help protect…… [Read More]

How does the concept of product life cycle apply to egal Marine products?
The concept of the life cycle applies to egal marine in several ways. First, this company appears to be in the maturity phase. There are discussions in the article that explain the different methods that they have utilized to stay cutting edge and with supply and demand. As the years passed, they would create bigger and better boats that would in fact cost more and make more money. egal was in the growth stage when they were getting new suppliers while they continued to make updates and innovations to their product. Penfield (2009), explain that companies that can implement effective waste-recovery systems will have a competitive advantage over other businesses. They further explain that in the current economic environment companies need to look at waste as an opportunity we cannot afford to squander.…… [Read More]
imagery in the movies Chinatown and Blade unner and compare the film-noir type of imagery against the actual statistics available in the latest Census results from Los Angeles that characterize the complexion of Los Angeles in 2010. In all three arenas, we see a Los Angeles area that is multi-ethnic, grime and dirt included. In many ways, while the movie imagery is different, in many ways all three characterizations have more in common than have differences. In all three portraits, the dirty, gritty and repressive city scape has the potential to swallow up the inhabitants in the Los Angeles darkness that is almost as thick as palpable as the ninth Egyptian plague of darkness. The films accurately and effectively discuss the "feel" of the city and the city's neighborhoods. The author will provide examples from the films to illustrate this, as well as the similarities and differences.

Commerce and Its Demographics
The diffusion of ideas and technological impacts that have taken place globally.
Globalization as a phenomenon of economic and cultural connectivity has been growing for centuries, but the current form is of a fundamentally different order (Smith and Doyle 2002). The speed of communication, the complexity and size of the networks involved and the huge volume of trade, interaction and risks involved make up the current and peculiar form. The diffusion of ideas, practices and technologies that occurs within is more than internationalization, universalization, modernization and westernization. Anthony Giddens (1990 as qtd in Smith and Doyle) described today's globalization as "the intensification of worldwide social relations, which link distant localities in such a way that local happenings are shaped by events occurring many miles away and vice versa." It has changed the way geography has been traditionally understood and how localness has been experienced. The new…… [Read More]
