Ozone depletion, greenhouse effect, acid rain essays

Ozone depletion, greenhouse effect, acid rain essays Everyone knows that the atmosphere and the pollution in the world is very dangerous to everything and everyone. But how bad are these different things that affect us and everything around us? This paper will specifically look at the effects, global effect and the treatment on acid rain, the greenhouse effect and the ozone depletion. Acid rain has been around for a long time. It was first noticed around the 17 century during the industrialization period. Scientists have been paying attention to acid rain since that time and the effects it has had on the plants, animals, humans etc. Acid rain is very dangerous as most people know. First off the term is not totally correct and scientists prefer the terminology acid depositions. The reason these scientists believe that it is called acid depositions instead of acid rain is simply because the acid which was formed by pollution can in fact return to the earth as either solid or a gas and not only in the form of rain. Acid depositions can come in rain, fog or even snow. Industries, factories, vehicles, aerosol cans, etc are all causes for acid rain. This is because all of these things increase the level of sulphur dioxide and nitrogen in the air we breathe in. These chemicals will later transform into sulphuric acid as well as nitric acid which in the long run will co me down in the form of acid rain. Electric companies have to burn a lot of coal, which contains a very low amount of sulphur, in a days time which will increase the level of sulphur dioxide in the atmosphere. But the electric companies are not the only ones to blame; a lot of other companies and industries have to process raw ore (a mineral or a numerous amount of minerals which a valuable or constituent can be profitably mined or extracted) so they can obtain copper, zinc, and nickel. The problem with that is that copper, zinc, and nickel are also causes of acid rain. Most poll...

Brett Dennen - Ain't No Reason writing about the song and the video Essay

Brett Dennen - Ain't No Reason writing about the song and the video - Essay Example Speakers use what they know to find their attitudes on a subject and their understanding of a reader (Lamb 4). Summary of the text The song â€Å"ain’t no reason† by Brett Dennen talks about how things like ignorance, priviledge, and life’s daily routine get in the way not just of addressing but also recognizing the suffering around us. He talks about how many lives are been irreparably changed and hurt and the way our world has been destroyed and hence the future generation tends to have a bleak outlook. The reasons for this he explains are because of poverty, war, violence, hatred, genocide, environmental degradation, oppression and most importantly because we are unable to see the suffering that surround and end up working against it. This text can trigger the audience to debate about what it really means to be conscious of suffering and the moral obligations we have to make in order to effect change. Bretten stresses that we should passively understand that t he answer to all this is love. He describes it as a practice of kindness, compassion and respect among all the living things our planet included. He is strongly against the idea of living a disconnected life. Aristotle argued that it is possible to connect to your audience logically emotionally and ethically. These three forms what is referred to as the rhetorical triangle (Lutze 1). ETHOS (WRITER) LOGOS (TEXT) PATHOS (READER) (Henggeler 2). These three appeals in the triangle form a balance of what the writer should use to be able to form an effective argument. Each appeal is important to be able to produce a well balanced argument as they directly affect each other. Rhetorical appeals (ethos, pathos, logos) Ethos Ethos refers to character of a writer. This explores the ability to deal with a topic. (Metzeger 7). The writer or singer Brett Dennen is well conversant with the way people are living around him. This is evidenced by the way he refers to the way people are living around him. We are made aware of that by the fact that he says he does not understand or neither explains why they live the way they live yet they do it everyday.’ I can't explain why we live this way. We do it every day (Dennen n. p.)’. The writer is also able to explore the issue of politics of lies and also the deception used by those in power. Pathos Pathos refers to the arguments or rather the appeals to emotions. This can be viewed a show well the writer is able to draw the audience’s emotions and tap in to them. It is the role of the audience in the argument (Henggeler 1). The song artist Brett Dennen is able to draw the listeners emotions in his song ‘Ain’t No Reason’ and thereby has effectively used pathos to connect to his listeners. He is able to draw the emotions of confusion when he points out that he can’t explain why they live that way yet they continue to do it every day. ‘I can't explain why we live this way. We do it e very day (Dennen).’ The song artist’ is also able to explore the emotion of bitterness and also expresses the continuity of their suffering. The writer states, ’I gotta a basket full of lemons and they all taste the same’ shows of the continuous bitterness. This can also suggest that there is recurrence of the same things over and over again till they start getting used to the feeling of being bitter with the occurrences. Brett Dennen

The Boston Molasses Disaster Essay Example | Topics and Well Written Essays - 2500 words

The Boston Molasses Disaster - Essay Example A lawsuit was filed against the company and a bitter legal battle ensued after the disaster. Negligence and errors in design were finally proved to be the most obvious reasons explaining the tank failure. This event raised public morale to combat high handed corporates who did not pay much attention to environmental issues and public safety. And the technical aspects of the disaster are also extremely vital. A simple and stationary storage tank had behaved in a strange manner. This signals poor understanding of chemical engineering. Designing a storage tank is not just a mechanical engineering topic. Chemistry of the material to be stored in the tank is highly important. Continual research on the Boston Molasses Disaster can help the engineering community to learn from past mistakes and understand the importance of industrial safety in the context of holistic disaster management preparedness. Background The Boston Molasses Disaster: What happened? The Center for Chemical Process Safety or CCPS has furnished a very concise but informative description of the Boston Molasses Disaster. On 15th January 1919 morning, a large storage tank in northern Boston blasted releasing tons of molasses. The steel tank was 50 ft or 15 m high. It had a diameter of 90 ft or 27 m containing nearly 2.3 million US gallons of molasses. All the rivets sealing the tank walls were spattered in the manner of machine gun firing, and chunks of steel were hurled across the area. Consequently, a wave or molasses rising above 15 ft or 5m began to surge ahead from the site of the blast. The wave had a speed of about 60 km/hr and traveled across two bocks of the Boston city with great momentum. Consequently, 21 people were killed, above 150 were injured, several buildings and vehicles were smashed, and the municipal system was completely disrupted. See Figure – 1. (CCPS 2007) Figure 1: Photographs showing the site of disaster before and after the molasses tank failure took place. Source: CCPS (2007) 1.1.2 The technology/engineering involved The CCPS (2007) has utilized a sound technical a pproach to describe the disaster. This approach is contextual with relation to both the old and new paradigms of engineering. The old paradigm of early 20th century engineering technology was devoid of facilities like computer aided design (CAD), industrial control systems, etc. The new paradigm is modern 21st century engineering which has power of new discoveries and superior computing efficacy.

Jet Blue Essay Example for Free

Jet Blue Essay There are a few trends that have come into play over the past few years. These different trends range from pricing for the flight to in flight perks. It seems that the perks and other in flight amenities are what may be what makes the difference and will impact any of the airline company’s strategy. Due to major hikes in fuel costs over the past year the airlines have had no other choice but to start passing this expense on to the flyers. The airlines have been trying to come up with competitive ways to differentiate themselves from the competition. Many of the airlines even charge for you check bags also. According to Ethan Davidoff in his article The Cost Behind Checking Bags most airlines only charge $25 for a bag to be checked but there is Southwest Airlines that allows two bags to be checked before charging. With that said in the above mentioned article one can see that you definitely want to travel light because for more than one bag the prices start to increase all the way up to $600. Although Southwest allows two checked bags there are other airlines that allow one free checked bag and most have a weight limit of 50lbs. If one were to travel internationally it may be cheaper to just purchase brand new clothes when you land. Not to mention the convenience of not checking any bags or having to wait to pick it up when you land, etc. So not only have airlines starting charging to check bags but many have stopped providing food, unless the flight is over a given amount of time and you are usually paying for that snack. The above mentioned change in airline airfares has certainly affected many airlines’ strategies. Also as mentioned above it has affected them most specifically in what type of benefits, perks, or amenities that they are willing to offer their flyers. Jet Blue has certainly followed suite and done various things to try to set themselves apart Discuss Jet Blue’s strategic intent. Jet Blue says that their â€Å"objective is optimize our fare mix to increase our average fare and, in certain markets, utilize our network to maximize connecting opportunities while continuing to provide our customers with competitive fares† (jetblue. om SEC filings, p. 31). Like any other company they are looking to cut costs without hurting any of the aspects of their company that sets them apart (i. e. customer service, tv, radio). Jet Blue airline seems to have set its strategy to take advantage of the charges that other airlines charge. They have set themselves apart by offering things on their flights that other airlines either don’t have or charge for. Jet Blue allows the firs t bag to fly free, the second costs $35, and the third costs $75. Although they do not have wireless broadband yet, unlike some other airlines, they do plan to have it in place 2012, and this is so because all of Jet Blue’s aircrafts are being set up for ViaSat satellite wireless which is new and no other airline has. Jet Blue is testing the service for ViaSat and the FAA for testing to be approved for use on airlines. However on the ground in the terminal it does offer free broadband at most airports (http://www. jetblue. com/flying-on-jetblue/onboard/wifi. asp). A strategy held by Jet Blue like that of any business is to improve its bottom line. Jet Blue wants not only to be profitable while reducing costs but they want their customers to be happy and have a good flying experience. Jet Blue has a saying on their site that says â€Å"our standards beat their extras† (http://www. jetblue. com/flying-on-jetblue/). They aim to provide stellar customer service. As a matter of fact according to ehow. com Jet Blue â€Å"was awarded the Conde Nast Traveler ‘Readers Choice Award’ for best domestic airline† and â€Å"in 2008, it won J. D. Power and Associates ‘Highest Customer Satisfaction Among Low Cost Carriers in North America’ award (ehow. com). More specifically they also state on their website that they have † ranked ‘Highest in Customer Satisfaction Among Low-Cost Carriers in North America’ by J. D. Power and Associates for five years in a row† (http://www. jetblue. com/about/work/). Jet Blue airlines prides itself on its customer service. As noticed from the previous paragraph they have won awards for their customer service. It is no wonder that the company believes in making their customer’s flight experience a pleasant one since the company was started by â€Å"David Neeleman and a number of Southwest Airlines employees in February 1999† (ehow. om). Outstanding customer service is part of their strategy and it is one of their many features that puts them heads above the competition. Discuss Jet Blue’s financial objectives and whether or not the company has been successful in achieving this objective. Before even getting into the financial objectives of the company just reading the SEC report for 2010 really shows proof that Jet Blue has been an extremely successful company over the past ten years. Since they were incorporated in 1998, flight starting in 2000, they have grown from $38. million in net income in 2001 to net income of $97 million in 2010 (jetblue. com). The aforementioned data shows proof of growth and success in lieu of turbulent financial times with rising fuel costs. Fuel costs dramatically rose over the company’s time in business which could have easily put a company under but they continue to strive. Discuss Jet Blue’s strategic elements of cost, organizational culture, and human resource practices and evaluate whether each element provides the organization with a competitive advantage. Jet Blue continues to be competitive with their ticket and baggage pricing. In their 2010 SEC filing they term themselves a â€Å"value airline – based on service, style, and cost† (p. 4). They go on to discuss in the overview how they feel that they continue to provide â€Å"best coach product† and â€Å"reasonably priced optional upgrades† (http://investor. jetblue. com, p. 4). As for Jet Blue’s organizational culture their web site specifically says â€Å"If youre looking for a job where your career, your passion, and your sense of fun are all important then youve landed at the right place. At JetBlue weve built an award-winning brand based on delivering value, service, style and comfort to our customers — and to our crewmembers. And, by hiring people who share our vision, weve created a place where people enjoy coming to work† (http://www. jetblue. com/about/work/). Jet Blue continues remain un-unionized. Discuss Jet Blue’s strategies for 2008 and beyond and evaluate whether or not Jet Blue will be successful implementing these strategies. Part of their strategy in 2008 has been the same as previous and later years, to remain on time with their flights. They have continued to do well meeting this goal. Jet Blue’s ongoing strategy has been to deliver exceptional customer service and on time direct flights. In 2008 they stated in their SEC filings that they were the â€Å"7th largest passenger carrier† and in their 2010 SEC filings they were the â€Å"6th largest†. Regardless of any strategies that they planned to implement they were obviously successful. The proof lies in their continued recognition by JD Power Assoc, their net income increases, and their growth to 6th largest passenger carrier in the US. While other airlines are folding, being bought out, or merging Jet Blue is continuing to grow. It is no wonder since they offer outstanding customer service as only part of their strategy and it is one of their many features that puts them heads above the competition. Some of their other features that ranks them high with their customers is the fact that they offer 36 tv channels, XM/Sirius radio, and unlimited snacks and beverages to all passengers at no cost. Kudos to a company for keeping its employees (all non-union) and customers happy.

The Environmental Impact of Water Reservoirs Essay -- Environmental Im

[A water reservoir is a human-made lake that is created when a river is dammed to serve one or more purposes, such as to generate hydropower production, provide a water supply for drinking, irrigation, and flood protection] (www.eea.europa.eu). The effects of water reservoirs on the environment have stirred controversy since their introduction. Though water reservoirs can create many sought out improvements for a society it can detrimentally impact natural habitats and spawn a number of environmental complications. The debate on whether water reservoirs are truly beneficial or harmful towards human populations is ongoing as new projects like the Three Gorges in China are concluded. In the following essay I will be giving a critical review on the various negatives that arise from the creation of a water reservoir. The creation of a water reservoir will have a significant impact on the natural habitats that existed prior to its building. The surroundings around the damn will be inundated and reclaimed as part of the newly created water reservoir. The runoff of the initial filling of the reservoir will cause the existing plant life to die and decompose. For the first years stabilization will take place where the rotting plant life releases an abundance of carbon back into the atmosphere. Further on, the decomposing of plant material that settles at the bottom of the reservoir will produce and release large amounts of methane. A weakness to the argument that a water reservoir is green-friendly. Not only does local plant life and animal life suffer from this loss of land, the river itself is affected through vaporization. A water reservoir creates a greater surface area by which more water is evaporated and depleted from the ... ...an produce a pollution factor comparable to that of an oil driven power plant.

Punctuation error in your writing. Essay

Making mistakes in subject-verb agreement has always been my weakness when it comes to the grammar of my writing. I keep on doing the same grammatical lapses again and again. There are several rules regarding subject-verb agreement, of course, and being ignorant of one or two of them is forgivable, but what is unforgivable if you know the rule and yet continue to make the same mistake. The simple rule which I keep slipping n is the agreement of subject and verb in terms of number, especially in a present tense sentence. The rule states that when the subject is singular, the verb should also be singular. Inversely, when the subject is plural, the verb should also be plural. The difference between a singular and a plural verb is one letter â€Å"s† and oftentimes I would omit, usually unknowingly or by carelessness, putting that one letter. I have tried to correct the bad habit by being more conscious about my writing, during and after writing. While writing and every time I am to write an action word, I would constantly remind myself to look back to the subject of the verb. During revision of what I wrote, I would run through the entire piece with the one purpose of looking for subject-verb agreement mistakes. I would check for errors in punctuation, spelling, and style during the first revision, but focus on subject-verb agreement on the second run-through.

Internet shopping is also vulnerable to credit card fraud, from hackers that access credit card details saved to a website. Websites can also sneakily charge you with extra fees without you noticing, and can cost you quite a large amount. Another problem is that websites can usually only be paid with credit cards, not cash. This can be a problem if you are ineligible for a credit card, or do not have one for whatever reason. Retail shopping provides a great experience for the consumer, and can be better than internet shopping in some ways. When retail shopping, you can actually touch the product, and see it with your own eyes. This provides reassurance to the consumer that the product is the quality that they intend to buy, and can trust the store. Normally, if an item is boxed, the store will have a show model that potential buyers can interact with and base their decision of whether to buy it off of the functionality and price of that item. Retail shopping also allows the consumer to pay with cash, an option that internet shopping does not feature. This means that people can only pay for things with the money they have, and avoid credit build up on credit cards. On the other hand, some say retail shopping is not as good as internet shopping.Show MoreRelatedEssay on As Fashion Merchandiser1401 Words   |  6 PagesHow to Draw Strategy from a Comparison Shopping Report Millard’s Mini-Case As an FMM student you have already done lots of shopping reports.
