Air Pollution Essay Example for Free

Air Pollution Essay Air pollution caused by vehicles has been identified as the largest contributor to air pollution in the world. Air pollution caused by vehicles is when the burning of fossil fuels to power our vehicles gives off CO2 emission. This pollution by vehicles also produces toxic substances such as sulfur dioxide and carbon which can be fatal to humans. Air pollution also comes from industry as this source of pollution spews particulate matter and chemicals into the atmosphere. The output from factories includes sulfur dioxide, nitrogen dioxide, carbon monoxide and dioxide. Almost all of Earth’s atmosphere or ecosystem has been altered by the long-term effects of pollution by industries. Power plants are also another reason to blame for air pollution. They spread gases that thickens the atmosphere, causing the heat to be blocked from exiting to space. The gases are heavy, and comes down to the ground causing pollution One of the power plants that gives out the most pollution is the power plant that is fired by coal. Coal burning is a leading cause of smog, acid rain, and toxic air pollution. Not only that, it also causes the greenhouse effect and holes in the ozone layer. Health Effects Air pollution can affect our health in many ways with both short-term and long-term effects. Some individuals are much more sensitive to pollutants than are others. Young children and elderly people often suffer more from the effects of air pollution. Examples of short-term effects include irritation to the eyes, nose and throat, and upper respiratory infections such as bronchitis and pneumonia. Other symptoms can include headaches, nausea, and allergic reactions. Short-term air pollution can aggravate the medical conditions of individuals with asthma and emphysema. Long-term health effects can include chronic respiratory disease, lung cancer, heart disease, and even damage to the brain, nerves, liver, or kidneys. Continual exposure to air pollution affects the lungs of growing children and may aggravate or complicate medical conditions in the elderly. Air pollution also effects the human cardiovascular system as the inhalation of air pollutants eventually leads to their absorption into the bloodstream and transport to the heart. Some pollutants may also directly cause functional alterations that affect the rhythmicity and contractility of the heart. Causes of water pollution. Factories play a major role in pollution the water. Wastes from factories include toxins, such as lead, mercury and other contaminants. These chemicals are very harmful and can lead to serious health hazards. Fertilizers and pesticides used in agricultural farms, homeowners lawns and roadsides are a threat to the natural water source. When the pollutants runoff into local streams or rivers or drained down into groundwater, they contaminate the water completely. Mining is also another reason for water pollution. Heavy metals and sulphur components which are buried in the earth are exposed during mining and during rainfall these toxic chemicals are exposed, which results in acid rain.

Banquo and Macbeth Essay

Banquo’s Ghost appearing at the banquet is a graphic manifestation of the guilt that Macbeth feels. Since, Lady Macbeth needs to make excuses for Macbeth’s interaction with the ghost of Banquo means that the ghost is only visible in Macbeth’s eyes. During Macbeth’s coronation banquet, Lady Macbeth pulls Macbeth asides and asks him the reason behind his inappropriate behavior. Macbeth becomes angry because Lady Macbeth robustly accuses him of lying. When Lady Macbeth calls Macbeth a liar he replies, â€Å"If I stand here, I was him†(3.4.89). Trying to convince Lady Macbeth of what he saw, Macbeth has to prove to himself that he witnessed Banquo interrupt the feast. Baquo’s ghost is a figment of Macbeth’s guilt. Macbeth tries to convince himself that he sees a ghost and is not going mad. After realizing he is truly the only one seeing Banquo’s ghost Macbeth comes to the conclusion that â€Å"This [seeing Banquo’s ghost] is more strange / Than such a murder is†(3.4.98-99). Fear cuts deeper than a sword. Similar to his earlier epiphany, Macbeth accepts the fact that Banquo is dead on Macbeth’s account. When Macbeth returns to the table he proposes a toast that, â€Å"I drink to th’ general joy o’ th’ whole table / And to our dear friend Banquo, whom we miss†(3.4.108-109). Now, in a stage of acceptance, Macbeth is able to tame the million thoughts fighting in his head. Macbeth is in a state of denial. To insure himself that he is not going insane, Macbeth tells Banquo’s Ghost that â€Å"Thy bones are marrowless; thy blood is cold / Thou hast no speculation in those eyes / Which thou dost glare with†(3.4.114-116). Similar to when Macbeth tells his wife he saw a ghost, Macbeth tries to remain sane. We are not exposed to our real personality until something really awful happens. Once something bad happens all of the useless things fall away until we are left with who we really are. Work Cited Shakespeare, William. Macbeth. Ed. Barbara A. Mowat and Paul Werstine. Folger ed.

How to Use Footnotes in Research Papers

A footnote is a reference, explanation, or comment1 placed below the main text on a printed page. Footnotes are identified in the text by a numeral  or a  symbol.  Ã‚   In research papers and reports, footnotes commonly acknowledge the sources of facts and quotations that appear in the text. Footnotes are the mark of a scholar, says Bryan A. Garner. Overabundant, overflowing footnotes are the mark of an insecure scholar — often one who gets lost in the byways of analysis and who wants to show off (Garners Modern American Usage, 2009). Examples and Observations Footnotes: vices. In a work containing many long footnotes, it may be difficult to fit them onto the pages they pertain to, especially in an illustrated work.Content footnotes  supplement or simplify substantive information in the text; they should not include complicated, irrelevant, or nonessential information...Copyright permission footnotes  acknowledge the source of lengthy quotations, scale and test items, and figures and tables that have been reprinted or adapted.Content FootnotesWhat, after all, is a  content footnote  but material that one is either too lazy to integrate into the text or too reverent to discard? Reading a piece of prose that constantly dissolves into extended footnotes is profoundly disheartening. Hence my rule of thumb for footnotes is exactly the same as that for  parentheses. One should regard them as symbols of failure. I hardly  need to add that in this vale of tears failure is sometimes unavoidable.Footnote FormsAll notes have the same gene ral form:1. Adrian Johns. The Nature of the Book: Print and Knowledge in the Making (Chicago: University of Chicago Press, 1998), 623.If you cite the same text again, you can shorten subsequent notes:5. Johns. Nature of the Book, 384-85.The Disadvantages of FootnotesMore than one recent critic has pointed out that footnotes interrupt a narrative. References detract from the illusion of veracity and immediacy . . . . (Noel Coward made the same point more memorably when he remarked that having to read a footnote resembles having to go downstairs to answer the door while in the midst of making love.)Belloc on Footnotes[L]et a man put his foot-notes in very small print indeed at the end of a volume, and, if necessary, let him give specimens rather than a complete list. For instance, let a man who writes history as it should be written — with all the physical details in evidence, the weather, the dress, colors, everything — write on for the pleasure of his reader and not fo r his critic. But let him take sections here and there, and in an appendix show the critic how it is being done. Let him keep his notes and challenge criticism. I think he will be secure. He will not be secure from the anger of those who cannot write clearly, let alone vividly, and who have never in their lives been able to resurrect the past, but he will be secure from their destructive effect.The Lighter Side of FootnotesA footnote is like running downstairs  to answer the doorbell on your wedding night. 1 The footnote has figured prominently in the fictions of such leading contemporary novelists as Nicholson Baker2, David Foster Wallace3, and Dave Eggers. These writers have largely revived the digressive function of the footnote.(L. Douglas and A. George, Sense and Nonsensibility: Lampoons of Learning and Literature. Simon and Schuster, 2004) 2 [T]he great scholarly or anecdotal footnotes of Lecky, Gibbon, or Boswell, written by the author of the book himself to supplement, or even correct over several later editions, what he says in the primary text, are reassurances that the pursuit of truth doesnt have clear outer boundaries: it doesnt end with the book; restatement and self-disagreement and the enveloping sea of referenced authorities all continue. Footnotes are the finer-suckered surfaces that allow tentacular paragraphs to hold fast to the wider reality of the library.(Nicholson Baker, The Mezzanine. Weidenfeld and Nicholson, 1988) 3 One of the odd pleasures in reading the work of the late David Foster Wallace is the opportunity to escape from the main text to explore epic footnotes, always rendered at the bottoms of pages in thickets of tiny type.(Roy Peter Clark, The Glamour of Grammar. Little, Brown, 2010) Sources Hilaire Belloc,  On, 1923Chicago Manual of Style, University of Chicago Press, 2003Anthony Grafton,  The Footnote: A Curious History.
