What Is the Ozone Hype Anyway?
“The ozone is a pale bluish form of oxygen gas with an odor like chlorine, formed by an electrical discharge in the air” (Webster 185).
The first time that I thought about this research narrative was the first time that I read the syllabus for class. My immediate reaction was that I could not believe that we were actually going to write a ten-page narrative. I was never expected to write a paper of this length before and I was unsure if I were going to be able to do so. However, it turned out that it was not that bad, although I did go through many frustrations along the way.
First, I had to come up with a topic. I think that this was the hardest part. In our class, we used one of our textbooks to help with this part of the process for our papers. In exercise 1.1, Ballenger suggests that you make a list under a number of different topics (23). Therefore, I made a list of at least twenty things under each topic that I thought might be a possible topic for my paper. My list ranged from pets all the way to relationships and back to health problems. However, after talking to my professor and my friends, and taking Ballenger’s advice on how to eliminate topics, I decided to go with the ozone layer (25). I had a few different reasons for making this choice. One of them was that this was something that I did not know very much about. In addition, the topic was something that I did want to know more about. Consequently, due to the fact that I did not know much, I would not do my research with a bias and more importantly, I would do the research well because I wanted to know more.
Next, I had to come up with a question that I wanted to know the answer to. Again, Ballenger came with help. In exercise 2.1, Ballenger suggests that you make a list of questions and then have peers add questions also. During this process, I went through so many questions. Why was the ozone layer depleting? What could we do to help? How long has this been going on?
...d for the general public in order to raise social awareness in preventing polluting the world. It is important to raise social awareness on topics of this nature because it is affecting our world. It is important to consider it as every individual problem and concern rather than see it as an external issue. Saukko chose a whole new approach and technique to get into people’s mind. Usually, authors that want to point out and raise social awareness on issues of this nature, tend to be direct and straightforward about it. However, Saukko has taken it to the next level by approaching the readers in a unique way that will catch more of their attention and hopefully move their emotions on the topic.
Bal, Mieke. Narratology: Introduction to the Theory of Narrative. Toronto: University of Toronto Press, 1985.
“Drawing on appropriate theory, deconstruct a narrative to show how it operates on the psychological, cultural and/or ergodic level within the interactive text of your choice.”
I did not read this short narrative just to read it. What I began to do was put myself in the shoes of the student whom
“Environmental Studies” were the most interesting and abstract words I had ever seen preceding “High School”. For this reason and the fact that it was near Central Park, I decided to apply and then attend. Because of the central theme of my classes I have been exposed in the shape of special speakers and class discussions to others who share my fear but not my growing sense of hopelessness. Quite recently, it has become more and more important to me that I am a part of the solution for the problems facing the environment. It is fear that I feel when I allow myself to dwell on the ignored warnings and the very complicated mess of problems and impossibilities that plague this planet. I don’t understand why there is even the possibility that one of the last natural, pristine ecosystem, in North America, namely that of Alaska, is in danger of being ruptured by the ever-powerful oil companies. I don’t understand why the heads of state who are infinitely more knowledgeable than me on the dangers of continued abuse of our gracious home don’t drastically and immediately cause change. I don’t understand why people haven’t listened. I guess it’s because they are not fifteen and scared.
The depletion of the ozone layer has been a trending topic after it was first discovered in 1970. The ozone layer is a portion of the earth’s stratosphere which absorbs most of the sun’s UV rays hence preventing cancer and other fatal illness to the skin. It contains high concentrations of O3 and at a constant rate is being broken down and. Since 1970, it has been discovered that about 4% of the ozone layer wears off every decade and is as a result of day-to-day human activity.
In the simplest form, there is a basic structural pattern to narratives, as expressed through Tzvetan Todorov’s explanation of narrative movement between two equilibriums. A narrative begins in a stable position until something causes disequilibrium, however, by the end of the story, the equilibrium is re-established, though it is different than the beginning (O’Shaughnessy 1999: 268). Joseph Cam...
As with most group projects, I started out with a basic understanding of the issue; essentially pollution and environmental changes humans make impact the environment in very bad ways. I grew up with a family who believes in intelligent design, young earth theory, and they all vehemently deny that anything humans do cause damage to the planet- everything reported in the news or by scientists are part of a larger “Liberal Democrat conspiracy.” Thus, my views had become largely hazy and even though I pride myself on being a Liberal, educated, intelligent young person, sometimes I was unsure what was actually true or what had been dramatized or exaggerated by scientists or the media to actually get people to pay attention. In addition, I also
ATTENTION GETTER: Every day, I see the effects of pollution. From the trash that’s thrown into bushes to the murky lakes to the smog-filled skies, these are examples of the negative human impact on the environment. PURPOSE (state specific purpose, relate topic to audience and establish credibility): The cars we drive every day release toxic exhaust gases into the atmosphere that damage it. We should try to do better to reverse these effects now; otherwise, our world will continue to get filthier and eventually become uninhabitable.
The basic set of reactions that involve this process are: Cl + O3 -->ClO + O2 and ClO + O -->Cl + O2 The net result: O3 + O -->2O2 Chlorine is initially removed in the first equation by the reaction with ozone to form chlorine monoxide. Then it is regenerated through the reaction with monatomic oxygen in the second equation. The net result of the two reactions is the depletion of ozone and atomic oxygen.6 Chlorofluorocarbons (CFCs), halons, and methyl bromide are a few of the ozone depletion substances (ODS) that break down ozone under intense ultraviolet light.
Secondly, before my undergraduate training, I learnt about the heat wave in the summer of 2003 that killed over 35,000 people in Europe. Furthermore, I discovered the growing incidence of health-related events due to global warming and climate change. This prompted me to pursue Environmental Science as my undergraduate programme of study. Eventually, I understood environmental issues and the impact of unsustainable use of the environment. During my course of study, one of many issues that really caught my attent...
The ozone layer is one of the layers of Earth’s stratosphere. The ozone layer absorbs radiation that hits Earth from the sun. Ozone is a good trapper of types of radiations such as ultraviolet radiation or UV light. UV light can penetrate organisms’ protective layers, such as skin, damaging organisms’ DNA molecules. Ozone molecules are made up of three molecules of oxygen atoms and it is always being destroyed and naturally restructured however, chlorofluorocarbons (CFCs), which is a nontoxic, nonflammable chemical that contains atoms of carbon, chlorine and fluorine, is harmful to the ozone layer. Chlorofluorocarbons are used in manufacturing of aerosol sprays, blowing agents for foam, packing materials and refrigerants. Other gasses also affect the ozone layer by causing a hole in the gas layer; this is called the ozone layer depletion. In my view, the ozone layer depletion is hence significant and we as Earth’s residents should prevent the constant expansion of the hole as it results in severe diseases and mutations in organisms.
I decided to assemble a draft copy of the task is was assigned, since I was going to be busy during the next week. I used the many journals sourced by my group members, which was extremely helpful. My task focused on "why DDT should be banned", therefore I based my work on the negative impacts of DDT on the environment and the health of humans. I also focused on past occurrences, which influenced communities. I was thoroughly enjoying this topic, as it included many different types of problems. I also found information on alternatives to DDT, which was less harmful and extremely effective. I was baffled by the production of DDT in the United States, since they banned the use of DDT in their country. I gathered as much information as I could and processed it. I had two other teammates working with me on this task, and it was reassuring, as they could fill in the gaps I had missed out. This topic was not straightforward, as it focused on a variety of aspects, which was informative. I was extremely grateful for our group choosing this topic, since I had already grasped large volumes of new information with respect to this topic, which was
In conclusion, after completing this assignment, I have noticed that writing has come a long way from the beginning of time to now. After doing an analyzation of the two stories, I observed that there were a lot of differences and similarities between the two. Overall, I feel that this project helped me understand what to look for with similarities and differences and weighing them out. After this, I noticed the authors had different writing techniques and realized that not everyone writes the
The people who need it most are destroying the ozone layer. This problem can be traced back to the overwhelming increase in the world’s population. With more people on the planet, there will be use of more automobiles, CFC’s, and refrigerants. In turn, an increase in these products will yield an increase in air pollution.
