argumentative essay #2

Generally, junk food is ‘any food that is perceived to be unhealthy and of low nutritional value’ (Family Journal 2005, p. 3). Lin Tran (2005) also agrees with this, stating that consuming junk food such as chocolate bars, potato chips and sweets will raise the kilojoules intake and lead to obesity problem among children. Subsequently, demands that sale of junk food in school should be banned have been increased. Operators of school canteens, however, argue that the ban will erode their profitability as sale of junk food finances most of their income. A statistic released by School News (2005) shows that profit earned by Cook High School has decreased gradually after reducing the sale of junk food. Nonetheless, I strongly believe that sale of junk food in school should be banned because junk food brings health problems, changes children behaviors and leads to litter problem.

Firstly, the unhealthy consequences of consuming junk food are clearly noticed where childhood obesity problem is presenting an epidemic pattern in Australia. The fact that preferences of children toward junk food are increasing has been proven through a survey conducted by Australian Nutritional Journal (2004). The data shows that more than 50% of children consume food containing fat more than recommended intake. Paradoxically, less that 25% consume fruits and vegetables with recommended intake. By selling food that contain a lot sugar and fat, school canteens are obviously causing the increase in weight of youth (Reynolds 2005). Childhood obesity will lead to fatal diseases like heart diseases, osteoarthritis, and cancers in future. Besides, frequent consumption of soft drinks will decline the dental health of children.

Other than that, students’ behaviors tend to worsening due to over consume of junk food. Dr. Cray (2005) in The Food Showa claims that with the ease of availability of junk food in school, children cannot get the daily nutrients needed. This will retard their growth and development as well as their learning potential while triggering behavioral problems. There is no doubt that students’ eating habits on what they like to eat are determined at home. But sale of junk food in school canteens will add insult to injury where students will not be able to improve their habits. Once they can buy junk food easily from school canteens, they will be eating whenever they like without any consideration and it will affect their studies. Cancelling the unhealthy junk food from students’ diets can result in the improvement of their behaviors (Caputo 2005).

Another adverse effect of selling junk food in school is the litter problems generated. Junk food packaging which include cans, crisp packets, cartons and plastic containers will be thrown everywhere in the school by students. This indirectly contributes to the safety hazard of students (Family Journal 2005). It is absolutely true that increased litter problems will cause cleaning costs being pushed up while the image of school also being affected. If the sale of junk food in school is removed, school groundskeepers will be able to save time on cleaning the grounds while having additional time to do other maintenance projects (Green 2005). In short, banning the sale of junk food in school is beneficial as litter problems are solved.

To conclude, sale of junk food in school will bring bad effects to both students and school where it prompts health, behavior as well as litter problems. A sports nutritionist, Adrian Cook (2005) says that junk food can be nutritious if children eat them with moderation. Hence, parents have to cooperate with school authority in educating children to eat and drink moderately. After all, sale of junk food in school ought to be banned.

What are the potential effects of global warming in terms of climate change and how can they be arrested?

29th August 2005, a devastating day for residents of New Orland, U.S as their homeland had been damaged by the evil Hurricane Katrina. This incident, on the other hand, has signalled human that they are receiving the consequences of what they had done to the earth which causes global warming. Generally, global warming is caused by a phenomenon called greenhouse effect. According to scientists, it is good to have greenhouse effect as it helps to keep our earth warm but the industrial development nowadays are gradually increasing the amount of carbon dioxide emitted into the air, causing erratic climate change (Woodford 2006). Certainly, the effects of global warming are unavoidable but immediate actions should be taken to minimize it.

Firstly, the potential effect of global warming in terms of climate change is the rise of sea level. Increase in world temperature warms up the earth and subsequently ocean warms up too causing water to expand. In the end, the ocean water takes up more volume and sea level rises undoubtedly (Woodford 2006). Besides, North and South Poles are also warming dramatically, surging the melting of ice shelves. According to An Inconvenient Truth (2007), the main character, Al Gore says if ices on Greenland melt completely, water will cover the low-lying places. Cities like New York, Calcutta, Beijing and Shanghai will be awash in sea water while Netherland will be demolished entirely. To summarize, global warming is causing rise in sea level and the topographical change of earth.

Another potential effect of global warming will be the damage of natural ecosystem including the loss of human lives and species extinction. Extreme weather which is unpredictable has led to series of mishaps such as tornados, hurricanes and typhoons. These disasters have taken away millions of lives and caused a huge damage of civilian properties. Furthermore, climate change will put plants and animals in jeopardy. For instance, parts of coral reefs have been killed, affecting aquatic animals that depend on them (An Inconvenient Truth 2007). Shorter winters caused by global warming fail to kill insects, prompting the risk of infestation (Riebeek 2007). New-breed vectors of diseases are predicted to spread much further. The fatal diseases such as SARS and Avian Flu have caused chaos on earth (Woodford, 2006). In brief, global warming in terms of climate change has shown disastrous effects on the biological balance of earth.

Al Gore in the film An Inconvenient Truth (2007) said, “Each one of us is the cause of global warming but we can make choices to change that.” Hence, solutions should be implemented in addressing global warming. Prior to that, carbon emission must be reduced by all means. Carbon tax established in some developed countries is a good way to start it. The ways in reducing global warming include using energy efficient appliances, hybrid cars; planting trees; weatherizing houses; practicing recycle and car pulling;. Walk or ride bicycle will be a better way. Woodford (2006) discusses another requirement is to possess political will where government should support the Kyoto Protocol, an international climate-change treaty. Overall, determination is the keyword in heading to the desire outcomes.

In conclusion, rise of sea level, change of global topography, damage of ecosystem and species loss will be deteriorated as long as the problem of global warming exists. Once global warming is not addressed, we will be experiencing the consequences. Therefore, concrete ongoing initiatives are needed in tackling global warming before it goes uncontrollable. “If you believe in prayer, pray that people will find the strength to change,” (An Inconvenient Truth 2007), we should not forget to protect our mother earth just to accumulate wealth as there will not be affluence without earth.
