Causes Of Pollution Essay Example For Students

Causes Of Pollution Essay Pollution is the introduction of harmful substances or products into the environment. It is a major problem in America and as well as the world. Pollution not only damages the environment, but damages us also. It has cause many problems ranging from lung cancer to the greenhouse effect. It is all among us and but we continue to live in our own filth. What is the reason behind this flawed logic? In this paper I will examine the problems and solutions for this issue. Automobiles are undeniable the greatest source of pollution. The noise pollution created by cars is immense. Another polluting effect of cars is the heat it creates. This heat makes it unpleasant to be near the car while its running. And of course the most famous of the automobiles evils is the exhaust. The toxic fumes given off as a byproduct of the combustion engine are slowly deteriorating our lungs and our atmosphere. The exhaust is extremely toxic to human beings. But why do we do continue to drive these walking time bombs. Some people will say it is progress, but the majority drives it for the convenience. Why walk four miles in four hours when you can drive the same miles in four minutes?Another popular source of waste is the post-consumer market. American citizens throw away millions of tons of garbage each year, and this trash has to go somewhere. While there are projects underway to clean and reuse this refuse most of it gets dumped into huge landfills. These landfills are disgusting festering blisters on our countrys landscape. But people continue to consume and throw away more and more in the name of convenience. As they see it, when things get old, throw it away and get a new one. They blame the government for the trash problem, but the truth blame should be placed on themselves. The last great source of pollution lays in the businesses. Although not common, businesses have been known to dump their waste products into streams, lakes, and rivers. This may seem like a relatively small occurrence that really is not your concern, but youre wrong. Each time one of these companies pollutes there are horrible consequences to pay. Mutations, destroyed ecosystems, and human death have all occurred as a direct result of illegal dumping. It contaminates our drinking water and soil. It causes entire communities of humans (not to mention animals) to move on to new places not to return for at least a century. The pollutants dumped by industry are so concentrated that a single barrel can destroy an entire lakes ecosystem. Not only do companies dump chemicals, but also hot water. This hot water kills most life it comes into contact with, but also causes an overgrowth of algae that covers the surface of the lake, or pond, and blocks the light from reaching the bottom. This me ans the plant life cannot grow, which mean the small bacteria and other microorganisms cant grow which means fish cant feed which means the ecosystem dies. Pollution like any other problem can be solved, but this is a long process. Individuals can do their part to save the environment as well as themselves. Instead of driving, carpool, take the bus or any other method of mass transit. This will cut down on pollution made by cars each year, not to mention your gas bill. When it comes to the trash problem, take the time to sort your trash and place it in the appropriate recycling bins. By recycling we reduce the amount of waste piled onto the landfills. As for consumption, pay attention to how the products you buy are manufactured and how they are packaged. Avoid those products made in unfriendly ways towards our mother earth. If a product encourages the destruction of land, or is of completely no use dont buy it. And finally voice your opinion in the polls. If each individual did their part, we will be creating a better world for ourselves as well as our children. .u2248253b209ae49d36e4f7c27c653599 , .u2248253b209ae49d36e4f7c27c653599 .postImageUrl , .u2248253b209ae49d36e4f7c27c653599 .centered-text-area { min-height: 80px; position: relative; } .u2248253b209ae49d36e4f7c27c653599 , .u2248253b209ae49d36e4f7c27c653599:hover , .u2248253b209ae49d36e4f7c27c653599:visited , .u2248253b209ae49d36e4f7c27c653599:active { border:0!important; } .u2248253b209ae49d36e4f7c27c653599 .clearfix:after { content: ""; display: table; clear: both; } .u2248253b209ae49d36e4f7c27c653599 { display: block; transition: background-color 250ms; webkit-transition: background-color 250ms; width: 100%; opacity: 1; transition: opacity 250ms; webkit-transition: opacity 250ms; background-color: #95A5A6; } .u2248253b209ae49d36e4f7c27c653599:active , .u2248253b209ae49d36e4f7c27c653599:hover { opacity: 1; transition: opacity 250ms; webkit-transition: opacity 250ms; background-color: #2C3E50; } .u2248253b209ae49d36e4f7c27c653599 .centered-text-area { width: 100%; position: relative ; } .u2248253b209ae49d36e4f7c27c653599 .ctaText { border-bottom: 0 solid #fff; color: #2980B9; font-size: 16px; font-weight: bold; margin: 0; padding: 0; text-decoration: underline; } .u2248253b209ae49d36e4f7c27c653599 .postTitle { color: #FFFFFF; font-size: 16px; font-weight: 600; margin: 0; padding: 0; width: 100%; } .u2248253b209ae49d36e4f7c27c653599 .ctaButton { background-color: #7F8C8D!important; color: #2980B9; border: none; border-radius: 3px; box-shadow: none; font-size: 14px; font-weight: bold; line-height: 26px; moz-border-radius: 3px; text-align: center; text-decoration: none; text-shadow: none; width: 80px; min-height: 80px; background: url(https://artscolumbia.org/wp-content/plugins/intelly-related-posts/assets/images/simple-arrow.png)no-repeat; position: absolute; right: 0; top: 0; } .u2248253b209ae49d36e4f7c27c653599:hover .ctaButton { background-color: #34495E!important; } .u2248253b209ae49d36e4f7c27c653599 .centered-text { display: table; height: 80px; padding-left : 18px; top: 0; } .u2248253b209ae49d36e4f7c27c653599 .u2248253b209ae49d36e4f7c27c653599-content { display: table-cell; margin: 0; padding: 0; padding-right: 108px; position: relative; vertical-align: middle; width: 100%; } .u2248253b209ae49d36e4f7c27c653599:after { content: ""; display: block; clear: both; } READ: My Last Duchess Analysis EssayBibliography:

Stages of Demographic Transition in Spain Between 1960-2008 free essay sample

This corresponds to the red square stated on the figure showing the demographic transition theory. At the start of the second phase the birth rate and the death rate are still high, but in this phase they will both decline to a lower level. The death rate starts declining earlier and it will decline faster than the birth rate. This will result in a remarkable growth in the population size during the second phase. A important factor for the decline of the death rate is the improvement in the standard of living. Other factors for this decline were improvement in health care and in hygiene. The decline in the birth rate during the second phase of the demographic transition theory is also a result of the improvements in the standard of living and in health care. The increase in prosperity resulted in a decline of the total fertility rate. Children were no longer needed to work in the industrial life to help their parents raise an income, and because of the improvements in health care, children were no longer needed to take care of their parents when they were old.

++i and i++ Increment and Decrement Operators

++i and i++ Increment and Decrement Operators These increment operators and the corresponding decrement operators are perhaps a little confusing to anyone who hasnt come across them before. To start with there are several different ways to add or subtract one. i i 1;i 1;i;i; For subtracting one there are the same four choices with - substituted for each . So why exactly does JavaScript (and other languages) provide so many different ways to do the same thing? Well, for one thing, some of these alternatives are shorter than others and so involve less typing. Using easily allows any number and not just one to be added to a variable without having to enter the variable name twice. That still doesnt explain why both i and i exist since both can only be used to add one and both are the same length. The reason for the two alternatives is that these are not really intended to be used as stand alone statements but are really designed to be able to be incorporated into more complex statements where you actually update more than one variable in the one statement.statements where you actually update more than one variable in the one statement. Probably the simplest such statement is as follows: j i; This statement updates the values of both of the variables i and j in the one statement. The thing is that while i and i do the same thing as far as updating i is concerned they do different things with regard to updating other variables. The above statement can be written as two separate statements like this: j i;i 1; Note that combining them together means we have eight characters instead of 13. Of course, the longer version is much clearer where it comes to working out what value j will have. Now if we look at the alternative: j i; This statement is the equivalent of the following: i 1;j i; This, of course, means that j now has a different value to what it had in the first example. The position of the either before or after the variable name controls whether the variable gets incremented before or after it gets used in the statement that it is used in. Exactly the same applies when you consider the difference between i and i where the position of the determines whether one is subtracted before or after the value is used. So when you use it separately as a single statement it makes no difference whether you place it before or after the variable name (except for a microscopic speed difference that no one will ever notice). It is only once you combine it with another statement that it makes a difference to the value that gets assigned to some other variable or variables.

7 Tips for Editing to Improve Usage

7 Tips for Editing to Improve Usage 7 Tips for Editing to Improve Usage 7 Tips for Editing to Improve Usage By Mark Nichol How do you make sure you’re writing right? Crafting prose is mostly a matter of using the right words for the job. Here are some steps to help you achieve that goal. 1. Look up the definition of an unfamiliar word and be sure you understand the meaning before you use it. It’s easy to deploy a word you’ve just read or heard, mistakenly believing you understand its definition or its connotation, only to confuse or accidentally mislead your readers. Always double-check a term you’ve never used before. (Consider doing the same with words you’ve used before and think you know.) 2. Search a thesaurus or a synonym finder for the precise meaning, taking care to notice the different connotations of similar words. Flag stock words and phrases, and thumb or click through a print or online resource to select a more exact or accurate synonym. But be alert to seemingly similar words with distinct senses. 3. Keep your writing clear and coherent, and avoid pretentious or overly formal language. Write to communicate, not to impress. Say what you mean, and mean what you say. Don’t dumb down, but don’t let your writing get in the way of your message. There’s a fine line between elegance and pomposity. 4. Select the strongest nouns and verbs before you select adjectives and adverbs. Words that modify nouns and verbs can enhance clarity of thought and vividness of imagery, but if they upstage the words they’re supposed to support, strengthen the actor and action words. When you do so, an adjective or adverb may no longer be necessary. 5. Seek opportunities to use repetition for rhetorical effect while, at the same time, you watch for careless redundancy. Take care that you don’t repeat yourself unless you do so to emphasize your point. 6. Read your draft aloud to help you refine grammar and usage. If something doesn’t sound right to you, it probably doesn’t read right to your audience, either. Recitation of your writing is time consuming, but that’s how you find the awkward wording or phrasing you didn’t stumble over in your silent review. 7. Ask someone else to read your writing and critique it. People you draft to read your draft need not offer solutions to problems of grammar, usage, organization, and logic; they can simply highlight problematic words, phrases, sentences, and passages, and offer more detail if necessary while leaving the problem solving to you. This last step isn’t practical for every writing task or assignment, but if a piece of prose is important enough to you, and you have a reliable, word-savvy person on hand, ask to borrow their eyes and the brain attached to them.

Aristotle Assignment Example | Topics and Well Written Essays - 500 words

Aristotle - Assignment Example Nicomachean ethics derives its name from Aristotle’s son, Nicomachus, for whom the books were dedicated. The central point in Nicomachean ethics is the question of the nature of a good life and how best man ought to live a good life on earth (Kraut, 2006). Aristotle’s answer to this was very fundamental in the development of virtue ethics in modern day philosophy. Nicomachean ethics begins by reflecting on whether there is an ultimate goal that all human life aims at. This goal is the ultimate good that all men hope to enjoy in their lifetime. According to Aristotle, such a goal must be complete, self sufficient, final and continuous. Aristotle concluded that the ultimate good upon which all human life should be based in happiness. The main objective of Aristotelian ethics is to find out how best one can achieve happiness. Human beings can achieve happiness when they live a virtuous lifestyle. Aristotle defines virtue as a disposition for one to act in the right way for the right reasons and derive happiness from acting rightly. Virtue is a mean between deficiency and excesses in ones actions. Actions must also be done voluntarily in order for them to be judged to be either good or bad actions. Virtue must emanate from an individual’s conscious choice and must have a purpose. In Nicomachean ethics, Aristotle discusses various virtues including courage, justice, temperance, patience and moderation (Kraut, 2006). Nicomachean ethics discusses various themes such as virtue and happiness, moral education, friendship, and the doctrine of the mean (May, 2010). These themes are spread across all the ten books that make up Nicomachean ethics. Virtue and happiness form the largest part of the discussion on ethics. Virtue leads to attainment of the ultimate goodness of human life, happiness (May, 2010). Another important part of Aristotle’s ethics is moral

Use of PEEP in Ventilation Essay Example | Topics and Well Written Essays - 2000 words

Use of PEEP in Ventilation - Essay Example A ventilator is a mechanism that provides sufficient oxygen to a patient from externally. Normally, during passive exhalation, the alveolar pressure is the same as the atmospheric pressure at the end of exhalation. Positive end expiratory pressure (PEEP) is used mainly to recruit or stabilize lung units and improve oxygenation in patients with hypoxemic respiratory failure thereby the pressure of the alveoli at the end of exhalation is maintained at appropriate level. Measurement of respiratory system mechanics in patients who are subjected to external mechanical ventilation suffering from low tidal volumes is important to assess the status of the ailment and to choose appropriate ventilator settings. (Pilar Saura & Lluis Blanch, 2002). Researches so far carried out have thrown light on the descriptive side of application of PEEP. However no controlled studies have been done to demonstrate the best method of choosing the level of PEEP. In fact most physicians hesitate to use PEEP lev el more than 10cm H2O.(Jesus Villar, 2003,) The primary function of the lungs involves the transfer of oxygen from the inhaled air into the blood and the transfer of carbon dioxide from the blood into the exhaled air. Whenever a patient suffers from the malfunctioning of lungs due to improper gas exchange he is supposed to be within the enclave of respiratory failure. ARDS, the Acute Respiratory Distress Syndrome is often the fertile soil for respiratory failure to get nurtured. In ARDS there is sudden respiratory failure due to the rapid accumulation of fluid in the lungs following an abrupt increase in the permeability of the normal barrier between the capillaries and the alveoli air sacs in the lungs. This damages the capillaries and alveoli air sacs. Leakage of fluid from the damaged capillaries to air sacs causing some sacs to collapse and some sacs filled with the fluid. This makes the lung stiff. Gas exchange is

Using ICT to Communicate Essay This is a 1959 English premier league football results table. The page layout for this is a portrait table. For this particular results table, there are not any images; I think this is because it is a results table for a football league.
