On Feb. 2, 2007, the United Nations scientific panel studying climate change declared that the evidence of a warming trend is "unequivocal," and that human activity has "very likely" been the driving force in that change over the last 50 years. The last report by the group, the Intergovernmental Panel on Climate Change, in 2001, had found that humanity had "likely" played a role." (Science, 5 December 2008).
Ozone and Earth's Homeostasis
The homeostasis on the earth is maintained by the presence of ozone, ozone makes a layer in the stratosphere which is roughly about 10-15 kilometers from the earth's surface. Ozone is formed when O2 and Oxygen atom O. collide with each other. When this reaction takes place the molecule O3 contains excessive energy, after the formation of the molecule becomes unstable, the excessive energy is discarded by colliding with another atom and the energy is transferred in the…… [Read More]
His government wanted HCFCs to replace CFCs. HCFCs are far less damaging to the ozone layer. They are used in refrigeration. He proposed that the deadlines for the cessation of the use of CFCs be advanced by a decade. The global agreement was to phase out CFCs among industrialized countries by 2030 and among developing countries by 2040. It was also later discovered that HCFCs warm up the earth a lot faster than carbon dioxide (Lean). HCFCs were first assumed to be beneficial alternatives to CFCs (aker 2000). These chemicals were found to be potent greenhouse gases, which heat up the earth up to 4,000 times more than carbon dioxide (Lean).
The Montreal Protocol was successful in immediately phasing out ozone-depleting chemicals, such as CFCs, by replacing them with less damaging alternatives (Sengupta 2005). Manufacturers of fire extinguishers and refrigerators could be commended for their response. ut the real effects…… [Read More]
Ozone and Global Warming
Globalism was one of the predominant changes made in the late 20th century. It combines economics, politics, and cultural movements that through the increased use of technology move the world closer together. If, in the modern world, actions are tied together, globalism should work because it delineates cause and effect in every area of the world. For instance, globalism has increased manufacturing and trade. Because of this, more pollutants are being placed into the atmosphere causing a number of controversial theories.
Global warming is the idea that there has been a gradual increase in earth's median temperature for surface air and oceans, based on the increase in greenhouse cases produced globally. Temperature variations have a dramatic effect on the globe due to the synergy between weather patterns, temperature, agriculture, and economics. Extreme weather patterns (e.g. dramatic changes in rainfall, freezing temperatures, storm systems, heat waves, etc.),…… [Read More]
Due to the Montreal Protocol signed in 1987 in which 160 of the world's nations joined together in banning CFCs and in an initiative to try to off-set any further effects due to emissions of gases that deplete the Ozone there are many recent reports that the hole in the Ozone layer is becoming smaller.
The "impressive global response to ozone layer destruction," were sung praises of the Secretary-General but also cautioned that it is not a time for complacency. There were minimum effects of decreasing to the ozone levels in the Antarctic during the decade of the 1990's. During 2000 and 2003 the hole extended over 10.8 million square miles or an area larger than the North American Continent.
All damages to the Ozone layer are not of the manmade type. It is known that volcanoes emit sulfuric acid droplets during the course of an eruption. Although it is…… [Read More]
2009). Though innovative, this use of the model appears to be highly reliable and appropriate given the context of the study. At the same time, very little direct observation is utilized for correlation to this data, and retroactive predictions are not presented to demonstrate the model's efficacy, raising some doubt.
Though the system of ozone depletion and recovery was thought to be fairly well understood given the decades of research on the subject, emerging data regarding significant influential issues that had previously gone unaccounted for have suggested that this understanding is not as complete or as accurate as was previously thought. Climate change is suggested in many of the studies to have a significant impact on the rates of stratospheric ozone depletion and recovery, which in turn is seen as having an effect on climate change in other studies. This potentially cyclical interaction gives rise to complexities that are…… [Read More]
A found this article particularly shocking for the immense figures suggested by the number of babies born daily. Such statistics opened my eyes to the core of the problem. Not only are we destroying the planet through our overindulgent, selfish and unsustainable habits, but also by the sheer number of us doing the same thing. No wonder studies such as the one in the first article found very little positive change in the environment around us. It is, as Connor says, time to raise our heads from the sand and face the core of our environmental problems. From the basis of sustainable population numbers, we can then create sustainable energy sources.

A study performed by Sarah Kang and Lorenzo M. Polvani from the Columbia University claims the Earth's ozone layer hole has affected atmospheric circulation in the Southern hemisphere all the way to the equator, leading to increased rainfall in the subtropics (Kang, 2011). Previous work showed the ozone caused a dominant westerly jet stream in the mid-latitudes to move toward the pole with accompanying shifts in precipitation patterns. This study used different computerized climate models in the effort to identify the impact of the ozone depletion compared to other factors. The experiment found moistening in high latitudes, drying in mid-latitudes, and moistening in the subtropics. etween fifteen and thirty five degrees south, the researchers saw about a ten percent increase in precipitation. The depletion of the ozone layer, from 8 to 25 miles up, has caused severe cooling in the stratosphere, expanding to the troposphere, and altering in…… [Read More]
The plan would be the result of the scientific method, through which the impacts and causes of the current environmental problems would be addressed. Additionally, the scientific method would sit at the basis of the future actions to be taken. These would traditionally include:
The search for alternative sources of energy
The search for renewable sources of energy
The creation of an infrastructure which allowed the propagation and populous use of alternative energies
The education of the population to reduce their levels of consumerism to life necessities
The implementation of stricter regulations which punish economic agents who pollute waters or cut the forests in an unsustainable manner
eplant forests, clean waters and support the sustainable life of the endangered species.
At a smaller size and specific level, the alternative and immediate action to be taken is that of reducing the harvesting of krill by commercial fishermen. This would be achieved…… [Read More]
Because of this discovery, scientists and politicians across the world have banded together in order to fight emissions and the use of products that contain CFCs. Most are aware of the grim forecast that awaits humankind if action is not taken -- a world consumed by ocean. Still, some do not believe that human behavior plays a role in global warming. hatever one's opinion, one can be sure that the worldwide attempts to implement responsible human interaction with the environment has a favorable political outcome -- globalization and the banding together of the world. In the future, history may write that chemistry was at the heart of a global political peace.

At the same time, research on ozone depletion showed the dire situation and helped support pushes for reform and regulation of harmful chemicals being used in such a vulnerable context as in our atmosphere. Many Western nations have passed legislation limiting the types of chemicals and levels which are acceptable, for example the Air Pollution Act in the United States (U.S. Environmental Protection Agency 2010).
With this growing amount of data, it is clear that stricter regulation will be necessary to curb future ozone and water pollution as a result of the growth of the aviation industry. We cannot completely ban airline travel, and so resources need to be implemented in finding safer alternatives for the harmful chemicals necessary in massive airline travel.

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]

Educational institutions have also taken an interest in the matter. Stanford University for instance has been engaged in promoting responsible behavior of the consumers. They have also conducted studies to reveal the impact of global warming and the performances achieved in reducing its negative effects. They have also promoted the sources of alternative energy (Stanford University, 1995).
The governments in several American states have also formed alliances to fight off the malign effects of global warming. "As more and more states band together to fight global warming, their efforts are moving beyond mere symbolism and becoming big enough to make a real dent in the problem [...] More than half of the nation's 50 states -- including populous California, Texas and New York -- have joined together in regional coalitions aimed at reducing greenhouse gas emissions from power plants, boosting the use of…… [Read More]
Americans will face important decisions as consumers, voters, and global citizens.
We need to understand that global warming has to be treated as a problem for all in order to properly solve it. If we continue to see it as a political issue as we sometimes do, it will never be fully resolved. Earth has to be made livable for everyone. It is not a place for first world or third world countries. It is a place for every human being and all life present here. Thus the issue must be seen clearly and humanitarianly instead of turning into another senseless political debate.

International egulation of Tourism in Antarctica
Since the mid-1980s, Antarctica has been an increasingly popular tourist destination, despite the relative danger of visiting the largest, least explored -- and arguably least understood -- continent on earth. Beginning with the 1959 treaty establishing Antarctica as an international zone free of claims of sovereignty by nation's that had been instrumental in establishing research stations there, there has been almost constant negotiation about how to administer regulations pertaining to the preservation of life forms on the continent, what those regulations should be, and what sanctions should be applied and by whom.
To understand the depths of the negotiations, and the potential for discord, it is necessary to understand what the continent offer the 65% of global nations that are party to the 1959 and all subsequent treaties. To understand the possible future of Antarctica, it is necessary to outline treaty attempts to minimize…… [Read More]
The former had been neglected. This was a very serious kind of neglect, she said. She concluded that unless the nitrogen problem was confronted and adequately contained, climate change would not be solved (ohan).
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]
One should always think of safety first when deciding to ride a bicycle, especially in a heavily congested area such as New York City.
Many cyclists will explain that the main reason they do not wear protective bicycle gear is because it is uncomfortable. No one likes to be covered up a lot while they are riding down the street. They claim that it interferes with their ability to properly maneuver the bicycle and could cause them to wreck the bicycle. Other cyclists will explain that the reason they do not use the protective equipment when they ride a bike is because they cannot afford them. Some cyclists even claim that they do not have time to be bothered by putting on and taking off protective equipment. Life is a very fast and busy in New York City and most people do not have time to be bothered by protective…… [Read More]
This is true regardless of your belief on this particular issue.
In the last work to be discussed in this document "Global arming and Ozone Layer Depletion: STS Issues for Social Studies Classrooms" there is a cry, by educators to come to terms with the facts about global warming and get a sense of how to teach these facts to educators and students. The information being given to educators is depressing, as one student educator stated and figuring out a way to teach the issues is difficult. ithout the development of a greater understanding of the "butterfly effect" of technology there will likely not be a more responsible humankind.
If the global warming trend continues, the results could be depressing indeed: melting polar ice along with thermal expansion of the oceans could raise the sea level, flooding coastal cities, and many agricultural landscapes could dry out, becoming deserts. And yet,…… [Read More]
technology for hybrid vehicles is proven to work, we as a nation should only build and sell hybrid vehicles to help reduce the damage done to the nation's air quality. Hybrid Electric Vehicles (HEVs) have reached the point that they are affordable for most drivers, they use less energy, and they are cleaner than gasoline and diesel powered vehicles. These vehicles make sense for today and for the future, and Americans need to recognize the importance of saving the environment over their attachment to large, fuel inefficient vehicles. As a nation, the people should support and demand that automakers only build and sell HEVs. It is time to take the nation's air quality into our own hands, and demand carmakers take responsibility for the decrease in air quality standards in America today.
Hybrid electric vehicles have been talked about for many years. It is only in the last decade that…… [Read More]
Environmental Hazards as a Consequence of Crude Oil/Natural Gas Exploration, Transportation, Refining and Storage
Ever since crude oil was first successfully drilled in the U.S. In Titusville, Pennsylvania, in 1859, the demand for oil has only been increasing over the years in countries all over the world. (Camden, 1883) Crude oil, from which various petroleum products are obtained, is a naturally occurring hydrocarbon component found trapped in rocks below the earth. The word "petroleum" means "rock oil" or "oil from the earth." Natural gas is another form of hydrocarbon that is also found in nature. oth crude oil and natural gas have excellent combustibility and are good sources of energy. Crude oil is not used in the extracted form; but it is refined to obtained products such as gasoline, liquefied petroleum gas (LPG), naphtha, kerosene, gas-oil and fuel oil. Secondary products during the purification of crude oil are obtained are…… [Read More]
Environmental egulations in Public Transit
The negative effects of air pollution are that it can force illness on us. It can produce burning eyes and nose and an itchy, irritated throat, in addition to difficulty in breathing. The cause for certain diseases like cancer, birth defects, brain and nerve injury and long-standing wound to the lungs and breathing passages is found to be some chemicals in polluted air. Severe injury or even death can happen if some hazardous air pollutants are released by mistake. Air pollution affects environment. Air pollution also affects trees, lakes and animals. Air pollutants are contracting the shielding ozone layers above the Earth. This loss of ozone can lead to alterations in the environment in addition to more skin cancer and cataracts in people. By soiling buildings and other structures, air pollution spoils properties like home, offices, etc. Damages to stone-based structures like buildings, monuments and…… [Read More]
Noncoding DNA, also known as "junk DNA" describes portions of the DNA sequence that do not appear to have any presentable use -- they do not encode for proteins, etc. In fact, in a most eukaryote cells, a rather large percentage of the total genome is noncoding DNA, but this varies between species. However, it is now a misnomer to call this material "junk," because the more sophisticated we become at biochemistry, we find that many do have subtle biological functions, including the transcriptional and translational regulation of certain protein-coding sequences. esearchers also belive that other noncoding sequences have a likely, but unconfirmed function, as an inference from high levels of inherited tratis and natural selection processes (Masters, 2005, 163-5).
esearchers know that the amount of genomic DNA varies widely between organisms, as does the proportion of coding and non-coding DNA within these genomes. For instance, 98% of the human…… [Read More]
Air We Breath
Contrary to the popular phrase "I'll go out for some fresh air," one might ask is the present air that we are breathing is still fresh? Or, has this phrase become irrelevant the present day world. Air pollution has been very evident ever since history entered industrial revolution. By the time we step our foot on our doorstep, the moment we open the doors of our car, the very first instance that we pull up the drapes and open our window, we are experiencing air pollution at its finest ....so to speak. Smoke billowing from a factory chimney, fly-ash generated by thermal power plants, and speeding cars causing dust to rise from the roads, smokes from cigarettes, and the list would go on and on. If there is a drawback when we speak of modern day technology it is the pollution it emits into the very air…… [Read More]

Ocean current is a problem because it has an effect on the greenhouse. Also, ocean currents are something that has been able to move vast amounts of all heat all over the planet. Also, winds are what push horizontally towards the sea surface and then also drive the ocean current patterns. There are as well interactions among the ocean and atmosphere can likewise create phenomena for instance El Nino which happens every 2 to 6 years.

Global Warming Trends and Impact
Global warming refers to the warming of the earth's temperature, in particular oceans and the layer of the atmosphere closest to the planet (Thompson, Lonnie & Gioietta 114). Thus far, the total temperature increase is documented at only about one degree (Weart 43). However, even this seemingly minor change can create ripple effects that present challenges for earth and mankind. Global warming and other climate change issues are thought to be the result of both natural phenomenon and man-made activity. In order to sustain life as we know it, the earth must maintain a consistent temperature. The rapid elevation in temperature has created an imbalance making it evident that the phenomenon of global warming is real.

Currently, the cytotoxicity of chrysotile, which is a type of asbestos, as well as Rockwool along with other man-made vitreous fibers (MMVFs) have been evaluated by cell magnetometry. This method established cytoskeleton-dependent functions of macrophages, which contribute to a significant role in phagocytosis, and is used to assess the degree of harm caused on macrophages (Kudo, Kotani, Tomita and Aizawa, 2009).
Biological consequences of MMVFs have to be looked at not only at the cell level but also in the lung. To date there have been no studies done to look at the safety of Rockwool by way of lung magnetometry. In a study done by Kudo, Kotani, Tomita and Aizawa, 2009, rats were forced to inhale Rockwood a nose-only inhalation exposure system, and then looked at by lung magnetometry, a biopersistence test and pathological examination. The well-being features and safe utilization of mineral wools have been looked at for…… [Read More]

Plastic is a non-biodegradable waste that has low recycling margin. Unfortunately, plastic is widely used in everyday products is heavily present in the municipal waste. The environmental threat posed by the presence of plastic in municipal waste is another major issue. Major plastic types that are commonly found in UK municipal waste include PET, high density polyethylene, polyvinyl chloride, low density polyethylene, polypropylene, polystyrene, and other plastics such as melamine. Major source of these types of plastic are fizzy drink bottles, bottles of detergents and washing liquids, plastic plates cups and spoons, bin bags,…… [Read More]

As scientist come up with new technology for the welfare of mankind in this world they end up producing luxuries. The attitude of the people towards the environment is changing due to the fact that they need more and more luxuries and this makes them destroy the environment, and this make environment to be polluted in different forms.
In the act of mankind living luxuriously, they sometime use instruments such as air conditioners, fridges and others that do release C.F.Cs in the environment leading to deplete of the ozone layer, Paul Kennard (2006). According to researches the depletion of ozone layer during 19th century when there was no much use of such things, is compared with for 20th century, it has been found that there is 50% increase of the depletion. Deforestation uncontrollable for the purpose of building with the aim of accommodation tends to raise the content of…… [Read More]
Greenhouse gases thicken the Earth's atmosphere trapping solar light waves that reach the Earth as a form of radiation. The solar rays are typically good for the planet as it keeps Earth's temperature habitable for life, but the extra levels of heat are warming up the planet. The heighten temperature is causing catastrophes on a global scale. The heat is sucking the moisture out of the land, causing desertification in certain regions, particularly Africa. Other places are experiencing higher levels of moisture and storms; a result of this is Hurricane Katrina.
The Montreal Protocol is treaty that is meant to protect the ozone layer by eliminating chemicals responsible for depleting the ozone layer. It was successful by helping to significantly reduce levels of chlorofluorocarbons and other harmful substances. It is a good example of how the nations of the world can unite for a common goal and institute…… [Read More]
Technology and Global Ecosystem
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]
tension between businesses interests in maximizing profits and the public's interest in receiving complete, truthful, and non-misleading information about products that they purchase.
The dangers against greenwashing are that consumers will have no confidence in the products or services they are buying. This means that they will not purchase specific items. As they feel they are being deceived and cheated through false labeling / misrepresentation. At the same time, there is the possibility that a firm could face penalties from government regulators who feel that they are engaging in false advertising. This will have a negative impact on the image of the organization and their ability to address the needs of customers in the future. ("Six Sins of Greenwashing," 2007)

There is money in recycling waste. Within BC, homes, hospitals and many other institutions there are bound to be some items that are left to lie without use for years. These might just one day end up in the dumpsites. Cell phones, ink cartridges, broken refrigerators, broken down cars etc. could earn one money if taken for recycling (Midwest Fiber, 2009).
ecycling also creates jobs. There are many stages through which an aluminum can will go through. From collection from the recycle bins in BC, the driver, the carriers, the off loaders, the recycle plant operators, etc. all benefit from the recycling process. So as the environment will be conserved, there will be no loss of jobs at the same time.

Additionally, Bollier further states the contrail emissions to cause warmer weather.
The duration of contrails in the atmosphere can last for days, according to (Harris, Kuper, Lebel, 2010). Trails may last for days and spread over hundreds of miles. According to Patrick Minnis, senior research scientist at NASA's Langley esearch Center in Virginia, "It helped us get a very good handle on the relationship between natural cirrus clouds and contrails, and separate the two effects. We estimate that contrails have an overall warming effect which is at least the same as aircraft CO2 exhaust, if not more." (Harris, Kuper, Lebel, 2010)
The white streaks (Murray, 2006), which characterize the contrail left by a flying aircraft is suggested by Murray to be removed as a contaminant by lowering the altitude of the aircraft during flight. Additionally, "because contrails are released at high altitudes, have a more potent effect on the environment…… [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.

Environmental Stewardship Project Proposal
What is Environmental Stewardship?
What are the problems?
Why do we need to be concerned about Air Pollution?
A proposed Innovative Strategy for Pollution Awareness
Today Environmental stewardship is on the rise and really needed in the community. This is because an increasing amount of people are out there making knowledgeable choices in their what they do every day, such as in the work places, and communities. These choices are considered to be good for the environment, for their finances, and for complete quality of life. By most, these actions are probably looked at as being inspiring because it shows and evidence of a developing societal commitment to environmental stewardship.
This report gives an outline of what I believe is the next step in a continuing evolution of policy objectives from pollution control to pollution sustainability and prevention. It likewise gives a reflection on the important…… [Read More]
The materials that are collected in them are solids from the various gases (which cooled inside these clouds). The gravity from the sun pulled them closer towards each other. This contributed to the formation of the planets and asteroids. ("Summary," 2007) (Williams, 2010)
Once a star is finished developing, is when solar winds will blow rock and debris away from the sun. This forms the Kuiper Belt and Oort Clouds, which is where the smaller debris is collected near the orbit of the outer body planets. These are the remains of the rubble that was used to create the solar system billions of years ago.
However, there is an exception to this pattern. In research that was conducted on distant galaxies, scientists discovered that there are not large outer planets with asteroid belts (i.e. Jupiter). This led to theories that much warmer Jupiter like bodies could exist closer to these…… [Read More]
European Union a state, or what else distinguishes it from other International Organizations
The primary question concerning global organizations as a medium of global governance relates towards the quantity and excellence of this governance within an era where we now have an overdeveloped global economy as well as an under-developed global polity (Ougaard and Higgott, 2002). There's a powerful disconnect amid governance, being an efficient and effective collective solution-seeking process within a given problem-area, and governance being the democratic legitimacy of policy formation. It has made possible the debate regarding 'legitimacy shortfalls' in main global organizations. Furthermore, governance has turned into a hosting analogy determining non-traditional performers (non-condition performers for example NGOs and their local and international associations) that participate as portable agents extending and expanding policy understanding, which is far more advanced and sophisticated than the traditional, elitist, government activities. The interest in global (as well as the regional)…… [Read More]
MacDougall may point out these facts but whilst doing so he refrains from the typical alarmism that often accompanies these tracts. It is unlikely that Earth will be (as per many of the alarmists) transformed into another melting Venus, and the oceans can still absorb much of the CO2 that we are creating, although MacDougall does admit that we are destroying hordes of the marine population at the same time. He also says that our ability to release carbon emission into the atmosphere will decrease with time since our known oil deposits are rapidly dwindling.
Earth has already experienced one interglacial warming period; the extra carbon in the atmosphere aggravates the situation. Earth too is impeded form reflecting the sun's energy back into space due to the constant melting of the polar ice caps and other glaciers, thus the warming is accelerated and intensified.

Fire Suppression Systems
Fire results when fuel, oxidant, and sufficient heat combine in time and place (New Zealand Institute of Chemistry, n.d.). The fuel is typically a carbon-based material like paper, wood, oil, or gas, while ambient air typically provides the oxidant in the form of oxygen. Other oxidants include nitrates, chlorates, and peroxides and therefore should never be stored alongside fuel materials. For combustion to occur the heat must sufficient to ignite the fuel. Once ignited the chemical reaction is typically extremely exothermic and becomes self-perpetuating in the presence of fuel and oxidant. If heat accumulates faster than it can be dissipated to the surrounding environment an explosion will occur.
The three ways in which heat can be dissipated is through conduction along a temperature gradient, convection due to movement of the gaseous fire matter, and radiation to other surfaces (New Zealand Institute of Chemistry, n.d.). The primary method…… [Read More]
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]
Over last five years, the government has begun to change focus in regards to its policies towards the Amazon. Where, it has designated a number of different areas as protected national parks. Currently, there are nearly 201 million hectares that are protected from development. Then, in 2006, a law was passed creating an agency to manage the forests and protect them. With the law stating, that all protected forests should remain public land and that these areas should maintain their forest cover. This is significant because it would reduce the total amounts of destruction that was occurring. A good example of this can be seen by looking no further than the State Acre. Where, deforestation decreased by over 50% since 1998. The main reason for the drop was: the enforcement of the new laws by razilian official and increased funding for social development in the area. According to the state's…… [Read More]
This is important, because physics has allowed the combustible engine to provide the world with a cost effective solution for traveling long distance. Sadly, the electric car can only be used for short to medium distances. Then, there is another potential problem that could be developing with the lithium batteries that are used, where China control 95% to 100% the resources for these batteries (lithium). This is problematic because they could restrict how much they are exporting (which they already have) to ensure that there is enough supply for the country to meet its own internal demand. (ryce 2010)
Despite this dire news, there are increased effort within the industry to support the use and development of such new technologies, to work in conjunction with the combustible engine. An example of this support for such technologies can be seen by the fact several oil companies hold the patents on several…… [Read More]
(Homer, 2007, pp. 37 -- 59) at the same time, many critics will find anomalies, highlighting how the opposite of warming trends may be occurring. Evidence of this can be seen by looking no further than, the blizzard that would blanket the Eastern United States in February 2010. As critics would claim that if global warming was such a problem, why is the nation experiencing unusual cold fronts during the winter. A good example of this can be seen with comments from a former climate change expert at the Energy Department Joseph Romm who wrote, "Ideologues in the Senate keep pushing the anti-scientific disinformation that big snowstorms are evidence against human-caused global warming." (roder, 2007) This is important, because it shows how many critics will often point to the information that is being presented as flawed. Where, they will find examples to highlight how the opposite trend could be occurring.…… [Read More]
This is a pertinent observation and one that is possibly central to understanding the problem of environmental ethics today.
Bugeja goes on to state that "…the new technologies that now keep us constantly connected also keep us constantly distracted" (Bugeja, 2008). He also makes the important point that, "Digital distractions now keep us from addressing the real issues of the day. Each of us daily consumes an average of nine hours of media through myriad technological platforms…" (Bugeja, 2008). In other words, we have become distracted from the holistic view of reality by modern communications technology to the extent that we are out of contact with the environmental issues that surround us.
Bugeja is also of the opinion that this situation has deprived us of the important aspect of critical thought. Critical thinking is defined as "… the ability to engage in reflective and independent thinking, and being able to…… [Read More]
As of May 2, 2009, CNN has reported there are 160 confirmed cases of swine flu across the United States of America and about 108 cases throughout the rest of the world.
Although the swine flu (H1N1) strain's discovery in the 1930s has shown not so much an aggressive spread of the disease through the years worldwide, a flaccid approach to the prevention and eradication of any communicable pathogen could result into a catastrophe worldwide, as transmission methods are numerous and casual like mere sneezing, coughing, and usual human activities, like handshakes, kissing and talking with an infected or healthy pathogen carrier.
Preventive measures include keeping one's self healthy by having a well-balanced diet, taking in ample or optimal amounts of water (8 glasses of water for normal individuals) to keep one normally hydrated, getting enough quality sleep and rest (normally 8 hours of sleep) with some stress relieving naps,…… [Read More]
A reduction in farm subsidies is stated to be necessary in order to improve access to market along with Common Agricultural Policy reforms, which should be "de-linked from production." Finally, stated as a requirement is that of a commitment for a 20% reduction in greenhouse gas emissions, which may be achieved "through market mechanisms..." (OECD, 2007) the OECD additionally states that structural reforms are required in addressing the challenges that the EU faces and while there is an improvement in terms of the economic prospects of the EU, "there is no room for complacency." (OECD, 2007) the OECD survey relates that the EU has the potential to play a critical role in the provision of solid conditional framework and the ongoing enhancement of the internal market in the EU.
The provision of the single market includes the wider range of goods access for consumers as well as a wider range…… [Read More]
While global warming may be of concern to the planet, the peak oil problem is of equal concern to the human element. Without the technologies we currently enjoy, lives across country boarders will be forever changed. Most scientists have already concluded that oil has reached its peak and can only decline until it has run dry. While drilling in the Middle East and Alaska holds some promise, it is only a temporary solution to the problem. If this peak oil problem continues to persist without significant fuel usage reduction or alternative fuel development, the future will quickly become oil depleted. Not only will the "me" of the future be unable to enjoy a quick trip to the supermarket or video store in a car or on a motorcycle, but also technological and medical innovations will cease, and research into the arts will be replaced by an overwhelming need for one…… [Read More]
hile hard facts, such as Venus' circumference, diameter, and distance from the sun are relatively easy to determine, historical and future implications of the planet and its study are not as simple to calculate. Two of the most important facts that we don't yet know about the planet Venus are the significance of its historical positioning and its implications for earth's atmospheric problems.
According to Ev Cochrane's study into the ancient solar system, the regularity with which the system now moves around the sun is a "recent development." In the ancient world, instead, Cochrane suggests that observers noted a different type of solar system. The discrepancies between the two solar systems has largely to do with the planet Venus. According to Cochrane, Venus' movement into its current orbit was recent, and this movement created solar side effects that may be important to the current development of the solar system. hile…… [Read More]
This would require the full support of government and state authorities to punish those who break the rules. For instance, officers should patrol the forests and severely fine the tourists who leave trash in the nature. Also, a radical change should come from the multinationals, which should respect stricter environment protection rules and should pay drastically when breaking these rules. The first point in this direction would be achieved once the population has an environment education and would then punish and ban the organizations which break these rules. With a damaged reputation and customers refusing to purchase their products, the corporations would have to reconsider their actions. Then, the second direction would appeal to the good will of the people and would state that the good deeds relative to the natural habitats are a social duty of each and every one of us. Therefore, if these two courses of action…… [Read More]
Rather, he believes that sometimes human beings have to go against nature to survive and to preserve their culture. However, some of the attempts he chronicles seem so quixotic, like an attempt in Iceland to cool the magma of an erupting volcano, the hubris of humankind borders on the ridiculous.
Many of McPhee's examples, like the potential for natural disasters in California, specifically the attempts of the Los Angeles County Flood Control District against avalanches in the San Andreas, seem prophetic. But ideologically, one substantial lacking is the book's refusal to reflect more seriously on how nature sustains human life, as well as threatens it. The threat of greenhouse gases show how, even in an era where technology seems to allow us to circumvent the pressure of nature -- from the need to be in darkness, to remain in one place, or to eat limited foodstuffs -- nature's demands will…… [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]
" (Capital, p. 915)
Ecological damage is grounded in resource depletion and density of population. You can have 10,000 over a 1000 acre land and this might not hurt the ecological balance but when you have the same number of people on 10 acre land, the balance is seriously disturbed as water, minerals, and other resources of a very small area are constantly being used up. This is what happened during the colonization process. Only some nations were constantly being robbed of their natural resources while nothing was coming from European countries. It must always be a two-way flow of resources because when its one-way, it leads to multifarious environmental and ecological problems. It is for this reason that Accion Ecologica argues "it's time to shut off the tap" to stem the "unjust flow of energy, natural resources, food, cheap labour and financial resources from the South to the North."…… [Read More]
Hybrid cars generally run quieter that the traditional IC engine cars. (Keelan, 2004) the very design of operation of the hybrid cars ensures that the engine turn off when stationary and start up on electric power and then switch to gas. This design could be risky to people who do not pay attention to the road and blind pedestrians. It is presumptuous to state that this is a negative for the hybrid cars. Any change in technology is always viewed with skepticism.
For instance, when cars with glass on all four sides were introduced, people were afraid to ride in them. This was due to the concern that they had regarding the safety of the vehicle if it met with an accident and the glass broke. (PBS, 2007) it took some time and observation of the benefits such as protection from the elements that convinced people that it was safe…… [Read More]
light does not turn on one must take several considerations in determining the cause of the situation. In order to figure out why the light is not turning on, analysis of the situation through the scientific method may be utilized. The first step is to pose the question of why the light does not turn on. esearch must then be undertaken to determine the cause. In this instance, there are three different approaches that can be undertaken. The first is to determine if the light does not turn on simply because the light bulb has burned out; the second is to determine if the light does not turn on because there is no power in the house, and if there is no power in the house, is the outage contained solely to the house or is it there an outage on a larger scale, perhaps citywide.
The first hypothesis to…… [Read More]
Ethics and the Environment
One of the most eminent challenges societies around the world is to find practical and economic ways to bring the benefits of economic growth to the developing world without damaging the environment. Whereas Beijing is the number one in the least of air polluters, Mexico City, the world's second largest city ranks on place four of the megacities with the most polluted air of any major metropolitan area in the world. There should be a combined consecutive approach of scientists and politicians guided by principles of ethics in government to make to transform the recommendations the scientific world operative.
I have chosen to review the following articles: Platt, Holden K. (9 July 2009) on "Chinese Air Pollution Deadliest in World." Platt wrote this article for the "National Geographic News" which is a magazine published by the National Geographic Society, based in Washington, D.C., USA. Existing since…… [Read More]
Political Issue and Tourism
Over the years, there has been concern over the fats shifting weather pattern occasioned by the global warming. Extreme and erratic weather conditions have been experienced in almost every part of the world. This essay will review the literature that is available on the definition of Global warming, the causes of global warming, effects of global warming on the community and nations, what the government is doing to stop global warming, as well as what Non-Governmental Organizations or Non-State Organizations are doing to stop global warming and finally what should be done to stop global warming.
The essay will also review the impact of global warming and community of Nations on tourism and how the changing weather patterns have impacted on the tourism trends from the human perspective as well as from the flora and fauna perspective. This will show how global warming has affected the…… [Read More]

For many the ability of a client to participate in pleading insanity is controversial. Many contend that this ability shows that the person is rational and should be punished accordingly. While others argue that, the ability of a person to know that they are insane does not make them sane. In either case, the insanity plea remains as a controversial subject.
Within the realm of psychology, the issue of insanity has always been a topic of interest. Psychologists have long asserted that there are various mental conditions that render individuals insane. These conditions include schizophrenia, bipolar disorder and even certain forms of depression. Psychologists contend that these conditions can make an individual unable to rationalize.
A book entitled Court-Ordered Insanity: Interpretive Practice and Involuntary Commitment explains that many cases involve the hospitalization or commitment of the client. In these cases, the book explains that the client mental…… [Read More]
United States is a large nation that is presently facing a multitude of problems. For many Americans the most important of these problems is the plight of the workforce and the unemployment rate among that workforce. The importance of this problem is reflected through the result of opinion polls conducted by a number of the country's leading pollsters. Displacing concerns with the economy as the nation's number one problem, the fact that unemployment now ranks as the primary concern highlights how serious unemployment has become in the United States. It indicates that the American workforce is eager to get back to work.
The unfortunate thing about the present unemployment figures is that they do not reflect the seriousness of the present situation. The figures do not reflect those who have ceased seeking employment, those working in positions below their capabilities, and those working two or three part-time jobs in order…… [Read More]
Marketing (Water Fans, India)
The market in India for water fans or misting fans as they are also called is problematical at best. Without doubt, the climate (except in the northern mountains) is hot; the problem is, it is also quite humid. Still, the Indian people have been looking for ways to stay cool for centuries. It was India that gave the world the slatted shutter; when air comes in through small spaces (as in shutters, adopted in the American South before air conditioning, or in lattice-work walls as in parts of India), it is cooled. Still, they did not develop a cooling system like that of that ancient omans, which did use water running through channels to create condensation. The reason, of course, is the problem of water quality. While industrial pollution has now added immeasurably to the water quality problems in India, the sluggish flow of…… [Read More]
Increased agriculture, deforestation, landfills, industrial production, and mining also contribute a significant share of emissions. In 1997, the United States emitted about one-fifth of total global greenhouse gases.
Global average surface temperatures have increased 0.5-1.0°F since the late 19th century. The 20th century's 10 warmest years all occurred in the last 15 years of the century. Of these, 1998 was the warmest year on record. Snow cover in the Northern Hemisphere and floating ice in the Arctic Ocean have decreased. Globally, sea level has risen 4-8 inches over the past century. Worldwide precipitation over land has increased by about one percent. The frequency of extreme rainfall events has increased throughout much of the United States. Scientists expect that the average global surface temperature could rise 1-4.5°F (0.6-2.5°C) in the next fifty years, and 2.2-10°F (1.4-5.8°C) in the next century. Evaporation will increase as the climate warms, which will…… [Read More]
