Human activities that contribute to harming the earth such as deforestation, and use of harmful chemicals should be stopped. Human Activities Harming the Earth One of the most dangerous environmental hazards is global warming; it is causing a dramatic increase in the temperature around the globe. Some people don’t think that global warming is actually happening and assume that the sun, glaciers and oceans are the only factors that are responsible for regulating the earths temperature and that computer models are not reliable since they are â€Å"guessing† the temperature change that would occur later on and that is true. There are many actions being implemented by humans that  harm the earth and its climate, some of which are deforestation, the use of CFCs and the increase of greenhouse gas emissions. First, deforestation is the removal of trees and plants for building and creating space for development, an ignorant person would think that this is a normal thing while on the other hand removing trees will increase the amount of carbon dioxide in the earth’s atmosphere because their removal would mean that there are le ss plants to photosynthesize. This process is like the breathing process of humans but it takes in carbon dioxide and releases oxygen anyone should at least know that this is a good thing because carbon dioxide is a harmful gas that also traps heat causing the earth’s temperature to increase because nothing is making a good use out of it. This is the cycle of how deforestation increases the temperature of the earth, Plants are removed, consequently Carbon dioxide in the atmosphere increase and causes the temperature in that area and anywhere the carbon dioxide goes to to increase. In addition to deforestation, the use of CFC’s (Chlorofluorocarbons) is also extremely dangerous since they contribute to an increase of cancer casualties. CFCs are most commonly used in fire extinguishers, air conditioners and refrigerators. As El-Hinnawi explains in the book Global Environmental Issues, When these gases are used, they rise to the atmosphere because they are lighter than air and are later on are converted by UV radiation to ozone-destroying catalyst to add on to this issue these gases are extremely stable. (1982, P. 61-63). These gases have been banned of use except in cases of emergencies but they still exist and are being used and they cause the ozone in the earth to deplete. This is caused when CFCs are used these gases are lighter than air; so they travel up the earth reaching the atmosphere that consists of ozone making a chemical reaction that changes ozone to oxygen. The ozone is responsible for blocking UV radiation from entering the atmosphere, but now since we have a â€Å"hole† in the ozone more UV radiation enters the earth this means we are more vulnerable to radiation that is cancer causing. Finally, the emissions of greenhouse gases. These gases are responsible for keeping the earth’s temperature warm and life supporting by trapping heat, but what happens when these gases are being emitted by factories and daily human activities such as transportation, electricity and agriculture the amount of these gases in the atmosphere is increasing and the issue is that these gases trap in heat  radiated by the earth that should instead be reflected out causing the temperature to increase then as a consequence more water vapor that is also a heat trapping gas thus causing a change in rainfall patterns, sea level, temperature and ecological balance. These activities include burning fossil fuels, industrial emissions or industrial processes. This means the more the greenhouse gas emissions the more the temperature would rise. To sum up, the fact that the planet earth is being harmed has to be accepted. Some of the many harmful activities that include but are not limited to deforestation, the use of CFC’s and emissions of greenhouse gases. Many solutions have been given by environmentalists to stop this mayhem and damage some of these are for deforestation is banning the cutting down of trees in specific places, encouraging agriculture and reforestation. For chlorofluorocarbons it is really unfortunate that there is no way for them to be removed except when they degrade after a 100 years or so, a decision to ban them has been taken prior to that (Montrà ©al protocol). Also, for greenhouse gas emissions many solutions are being worked on such as cars that run using electricity and using nuclear power, hydroelectric power and solar power to provide electricity. Human activities nowadays are definitely hurting the earth’s environment and these rules and restrictions have to be implemented. References How we know global warming is real. (2008).

Descriptive Beach Trip Essay

I had five hours until my sister was off work, check in was at three o’ clock and she had to be present to do so anyway, I had to find something to do for those next hours. The Tahoe was roomy and I was exasperated, only running on two hours of sleep, so I climbed to the back and dozed off only to wake up in a cold sweat thirty minutes later; there was no way I was going back to sleep with the bright and early sun beating down on the black truck. I needed to go somewhere I could stay cool and entertained for six hours. But where, I had no idea what there was to do in Orange County let alone how to get anywhere. Then it dawned on me, we drove three hours away from home, I had to be close to some sort of beach. I googled the distance from my destination to the closest beach, only a fifteen minute drive to what I call paradise. I typed New Port beach in the GPS, started the truck, turned up the music, and turned Right onto Mac Arthur Street. After driving for about thirty minutes I heard my GPS robotic voice announce â€Å"you have reached your destination.† Pretty disappointing words to hear when the only water you see is filling the gutters. I turned into a gated community and rolled down my windows to ask directions; instantly knew I was close as the humid, hot, salty air hit my face, and ran through my nostrils. The scent sent a smile from cheek to cheek, enabling me to greet the vale with a pleasant hello. I was directed to take a left at the light and follow the road, â€Å"You’ll know when your there, it’s hard to miss.† I followed the road becoming more irritated with every building I passed. Fed up I came to the conclusion at the next light I will just turn around and find something else to do. At the thought of giving up it came into eyesight, there it was unbelievably blue waters with white waves washing up on the shore. I finally made it to my little piece of heaven. After circling those narrow crowded streets for what seemed like forever, I got lucky with a car leaving right in front of the beach. I slipped on my bathing suit, slapped some sunblock on, grabbed my purse, water, and fruit and was on my way. Less then a minute walk to finally feel the warm sand against the bottom of my bare feet. The only thing between my mini vacation and I was a bike lane, I gent ly kicked off my sandals one by one, smirking as my feet hit the hot concrete and crossed the lanes into the soft, warm, light golden sand. With every step a sense a peace fell over me, taking in every grain of sand between each toe. Settling  for the perfect spot, right next to the hundreds of huge dark brownish red boulders. They provided a walkway about twenty feet into the blue waters. I laughed watching the little kids scream as a wave slammed into the rocks splashing up and over the top of them. I whipped my blanket into place and watched it slowly take form of each crater in the sand, sliding my dress downward, feeling every ray of the sunshine hit every inch of my skin in the most perfect way. I take a seat at the edge of my blanket allowing my feet to explore the roasting sand while my eyes observe every bluish green curl of water spiral over into white splashes, racing up onto the shore line then slip back into the waters just in time to see the next wave fold over into white splashes again. I closed my eyes as I lay back, soaking up the sun taking in every sound, picturing everything going on around me. In the distance I could still hear the joyful screams of the children after the sound of the wave crashing into the rocks. To the right of me I could hear the group of a few teenage boys trying to impress each giggling giddy girl; whatever they were doing was working. Right above me was the sound of about eight or nine gossiping young ladies, a few chuckling as they hit a volleyball back and forth with no net. To left of my feet was the faint unclear chatter of a younger couple, to the right was a mother with her children and her mother, talking to the family next to them about a wagon that had heavy-duty tires. She got it at Costco on sale for 49.99 it was the best thing she had ever invested in. As a bead of sweat ran in between the roots of my thrown up hair I realized how hot I was and how amazing the water would feel against my toasting skin right then, at that thought I heard the sound of eager excited screams from children in the water and popped up to see what all the commotion was about. I look over to see the kids on the rocks jumping up and down pointing to the water with mouth wide-open smile s, then look straight ahead confused at what they were so happy about. I slide my glasses to the top of my head just in time to see a pale-blue dolphin plunge out of the water and drop back in so smoothly, then another and another. The sun reflected on their silky blue skin giving them a shine each time they sprung out of the blue swell. My mouth dropped into an amused smile, I sat and watched them as they disappeared into the depths of the waters. Only 3 more hours to enjoy this amazing place, I wiped the sweat off my forehead and sauntered to the shoreline scanning for any more  wildlife as the water crept up to my feet. I let out a mild squeal when cold dirty white water rushed up mid calf. I began to walk out further as the waves came crashing down around my waist splashing onto my face and chest, causing goose bumps to cascade from my arms down to my legs. Past the tide, I stood still as the water softly sways me from side to side, enjoying the view of the sun shining down on the calm blue waters. I winced at the small knot forming in the pit of my stomach as the thought of sharks cross my mind. I watched the ocean start to shape and create a cerulean blue wave, curling over into a roaring hefty wave. I wait until the very last second to dive in as the white waters swallow me up me, feeling the heavy wave rip right over my body from head to toe. I pop out inhaling while I wipe away the water, with a harsh salty taste left in my mouth, I was ready to do that again. The current was strong I was a bit to close to the rocks so I swam opposite direction, either jumping with motion of the ocean or diving under each flood stream. I stayed out there enjoying every wave for a while. I lost track of how long I was out there but I knew I had to be leaving soon so I rode the waves back until the water was running past my thighs, fighting the waters trying to suck me back in. I got back to my blanket and realized I was only in the water for maybe forty-five minutes, two more hours to appreciate this place. I didn’t have a towel so I went to go air dry out on the rocks. I climbed bare foot and chose each rock carefully but quickly. I hope from rock to rock far enough to a silent spot whe re no one was around. As it got later in the day the waves got stronger, so I sat on the biggest rock amongst the middle to not get wet. I lay down with my shades guarding my eyes, keeping me from squinting and enjoyed the view of the open waters. I looked down and watched as the clear droplets slowly glide down the notably darker skin tone of my thighs. It was a pretty hot day; I dried up hastily and went back to my blanket. Four o clock, only an hour left to cherish this trip. I went back in the water one last time leaving just to feel the waves cascade over my head and leap over each ripple of water. I walked back to my blanket with thirty minutes left; I taste the variety of cold fruit and every so often the crunch of bits of sand. I watch the sun get lower, bitter sweet that I had to leave soon. Much more bitter then sweet in fact lets just say only bitter; I could have stayed forever. Such a sweet escape, with the sand sticking to every wet  portion of skin it comes in contact with, sea creatures popping in and out of water, the exquisite salty blue waters tossing and turning, the sound of children screaming as the tide collides with them. Everything about it is blissful. It was time to go, I picked up my bag, shook off my blanket and started to walk back towards the car. Started to walk back towards reality and further away from the worlds sweetest escape â€Å"At the beach, life is different. A day moves not from hour to hour but leaps from mood to moment. We go with the currents, plan around the tides, follow the sun. We measure happiness by nothing we can hold†¦ nothing we can catch. Everywhere†¦Life is jumping and elusive and momentously momentary. We want to stretch the day, distill the memories, make them last. At the same time, we know that the beauty is in the evanescence.†(Gingras, 24) Cites Gingras, Sandy. How to live at the beach.

Losing Weight Expository Essay

Losing Weight COM/150 Effective Essay Writing (AXIA) Struggling with the issues of weight loss and living a healthier lifestyle. Losing weight could be a short term goal, but the main idea is to eat and maintain a healthier lifestyle. Many Americans struggle with difficulties of weight loss, not only losing the weight but keeping it off. Different methods are used for losing weight, such as, exercise, various types of dieting and some medically needed procedures. Even though weight loss is vital to many people’s careers and futures, it doesn’t mean that it’s easier for these people than it is for you and me. The difference is that most people have a state of mind that they can’t afford to fail. So they are willing to pay thousands of dollars for personal coaching and expensive surgical procedures to lose the weight and keep it off. On a long-term basis, there is only one safe, effective, foolproof way to get down to a lower weight and keep off the extra pounds. That is eating a healthier reduced-calorie diet and getting enough exercise on a daily basis. Many have come to think that eating fewer calories means eating less food. However, it doesn’t mean that you have to walk around in a state of deprivation. A feeling of deprivation is the surest way to make your weight-loss plan fail. Most people find themselves eating more food when they deprive themselves. Most first-time dieters don’t enjoy counting calories because they quickly discover that it is time consuming and can become a complicated chore. Calorie counting goes hand in hand with feeling deprived that sometimes causes a person to back away from their diet. Struggling with weight-loss can be a very serious issue. The quality of your life and how long you live is to a great extent in your own hands. For what you choose to eat largely determines whether your body wards off or becomes vulnerable to a host of life-shortening diseases, such as diabetes, cancer, stroke, hypertension, and heart disease. But changing to healthy eating habits, especially if you have not previously followed the guidelines recommended by nutritionists, can be a challenge. One could have a normal number of calories but have them all from fat, and cause other problems that can lead to heart disease or stroke. Having a similarly unbalanced diet with all the calories coming from carbohydrates can lead to insulin resistance and diabetes, plus it's a really easy way to gain weight as you get older. It also promotes dental problems, especially if it's foods that tend to get caught in your mouth or on your teeth. The easiest way to do that is to avoid or at least severely limit intake of fast foods, candies, snack foods, and sweet desserts. There are all kinds of health issues related to over consumption of sugar. Diabetes would be the number one health concern. But, diabetes is not the only ill effect from over consumption of sugar. Obesity, thyroid dysfunction, kidney malfunction, and intestinal problems can all be directly associated with too much sugar consumption. Once your body has reached the point of unhealthy functioning, or you have placed such a strain on your body from over consumption that one of the related diseases has taken hold, it's almost impossible to correct one problem without creating another. Once you have become a diabetic, there are so many complications; simply choosing dieting and exercise is no longer an option. The health concerns you now have far outweigh the easy solution of diet and exercise. However, high blood pressure is also a known risk factor, for those that are over weight and have lack of physical activity and does not maintain healthy eating habits. The more you weigh the more blood your body needs to supply oxygen and nutrients. As the volume of blood circulated through your blood vessels increases, so does the pressure on your arteries. People who are inactive tend to have higher heart rates. The higher your heart rate, the harder your heart must work with each contraction and the stronger the force on your arteries. Lack of physical activity also increases the risk of being overweight with stress that can lead to temporary high blood pressure. If you try to relax by eating more you may only increase the risk of having hypertension. How to be successful with weight loss for a healthier lifestyle most people start by eating the right foods that can help us avoid certain diseases or recover faster when illnesses occur. These and other important functions are fueled by chemical substances in our food called nutrients. Nutrients are classified as carbohydrates, proteins, fats, vitamins, minerals, and water. Although humans need food to survive, many people eat too much, or choose the wrong foods to eat, which leads to the body putting on weight. When you eat more calories than your daily energy requirements the extra calories are stockpiled as body-fat. Slowly these fat cells keep building up and settle on the hips, waist, thighs, upper arms and back, as well as around the heart, kidneys, liver and other organs. Fortunately body-fat can easily convert into energy; however, you must reduce your fat intake and exercise regularly. If you only reduce your fat and don't exercise, your body will also break down muscle tissue and use them for fuel. Many people struggle to lose weight that is put on and that's where weight loss companies come to the rescue. There are many different ways for weight to be lost, as there are many different sorts of weight loss companies. Firstly there is exercise centers such as gyms and recreation centers which focus on fitness as the key to lose weight, Many varieties of pills, tablets and vitamin supplements are available that claim to make you lose weight. Meal replacement programs are available where the consumer has a liquid drink instead of a meal and this provides them with necessary nutrients. Diet plans are commonly found in magazines as well as the more common weight loss centers which some supply you with foods to eat and others inform you and assist you in making wise food choices. In conclusion, I found in order to be successful with losing weight for a healthier lifestyle you can follow techniques such as, eating more vegetables during meals as water-rich foods like zucchini, tomatoes, and cucumbers reduce your overall calorie consumption. Some other water-rich foods include soups and salads; they are good source of nutrition, take most of the calories before noon because studies tell that the more you eat in the morning, the less you'll eat in the evening. Moreover, you will get more chances to burn off those early-day calories than late-night calories, make water your favorite drink. A person must have a minimum of 8 glasses of water in a day. Avoid taking soft drinks or carbonated beverages; moreover replace them with water. Water helps in reducing weight in the most effective manner. Avoid taking white foods as they contain large amounts of carbohydrates, which may further lead to weight gain. Replace white sugar, white rice, and white flour with whole grain breads and brown rice. Eat fruit rather than drinking fruit juice. Eating whole foods will keep you satisfied for longer period of time than juice. Moreover, fruit juices are very high in calories. Use skimmed milk as it is high in calcium and low in calories. For coffee, use nonfat powdered milk. Don't stuff yourself with food in a single sitting; instead have 5 to 6 small meals or snacks in a day. Eating several small meals helps the body to release less insulin, which keeps blood sugar steady and helps to control hunger. More and more methods develop each day but studies show the most effective method is changing your diet mentally and physically challenging yourself. Picture this: The weight is over. Of course, this essay is not promising you that you will add years to your life, or that a funny and fabulous new personality will emerge. Also, it is not promising that you will become thinner than you’ve ever been when changing your eating habits. What it is promising is that a changed relationship with your eating habits will add benefits to your life even as it subtracts pounds and takes away your fear of regaining weight. Knowledge is power, as the saying goes, and the knowledge you gain from this essay can give you the power you need to change the most constant, necessary, and ongoing relationship that you have, your relationship with food. The knowledge you take from this essay should give you a realistic sense of just what is an appropriate goal for you. Genetic predisposition and even psychological factors can affect your weight. Therefore, for the person you are, there’s an appropriate weight at which you’ll look and feel your best. That’s the goal you want to aim for and maintain.

Operations & Quality Management (Singapore Airlines) Essay

Operations & Quality Management (Singapore Airlines) - Essay Example Singapore Airlines is quite an absurdity. It is the state-run airline for a country that is basically just a city; a nation that has residents of no more than 3 million; and a country that is just 250 kms across with no domestic routes to take over. Regardless of this it has managed to regularly post profits in one of the globe's mainly returning industries. According to higher executives, SIA evidently understands the high directive placed on it by discriminating and increasingly challenging customers. This causes a severe challenge internally in terms of being the finest in all aspect and places massive stress on the leading edge staff. Such high orders and anticipations result in a need to frequently alter and evaluate everything the airline carries out. Leading management is also faced with a continuous effort to form an unvarying service that is also extremely custom-made. SIA strategies all its procedures and sub-procedures in whole, with each getting unremitting concentration for enhancement and interrupted redesign (Heracleous, Wirtz, Johnston, 2004, pp.33-38). With such an international status for service quality, bringing terrific service is a most important challenge for SIA. The key is the company's entire approach - it knows that customers are buying a total bundle of service and that all its components have to do extremely well in every way. Introduction To persist as a service leader in the airline industry SIA makes it targets to create a "wow outcome" and to often blow customers. It does this by paying attention deeply to its customers and continually making out "wow" opportunities, such as not so heavy and more nutritious and hygienic food and an e-mail service within flight. Such new plans are also designed by feedback from staff, information about several other airlines, study of complaints, claims and compliments, and main traveler surveys. SIA's detailed feedback mechanisms gather information from different sources, all of which is analyzed then. Difficulties and faults are publicized internally to the extent that is possible. Quality Customer Service Singapore Airlines (SAI) is a model of constancy. The airline can possess 3 decades of continuing achievement, even affluent during times when the industry as a totality struggled. Its assets of awards include a confounding 67 international honors in 2002 only. How has this height of success been maintained for such a long period By implanting a customer-oriented culture that permeates all the airline's dissimilar operations. Significantly, though, an understanding of the want for cost usefulness grounds client service quality. All workers share this attentiveness. Holistic teaching techniques compel the message home, as does the reality that extra benefits and other incentives are very much reliant upon earnings produced. Not astonishingly, staff at all levels negate of resources being misused. Evidently you don't remain at the peak for 30 years by standing motionless. Modernization is a must and SIA is a sharp operator where this is noticed. The company considers that all improvements have some degree of shelf life and is not scared to break up with those

Jaguar Land Rover Case Study Example | Topics and Well Written Essays - 500 words

Jaguar Land Rover - Case Study Example Having said that different models of Jaguars are manufactured in different areas such as Birmingham, Liverpool and Solihull all in United Kingdom. Being the major wealth generator for UK there were 78 percent of Land Rovers exported to 169 countries and about 70 percent of Jaguars were exported to 63 countries and through importers and franchised dealers sales are being made. Around September of this year when Jaguar Land Rover stopped the operations in one of its two West Midlands plants but still committed to keep the Merseyside plant open. This would mean job losses will only happen to West Midlands. Reason being was to save money and not to create more jobs as the management is trying to avoid any redundancies. Hearing the news on one of the West Midlands plant closing came not a surprise to everyone as this was already anticipated several years back since opening 3 sites on current volume will really cause the Company lose some money due to below capacity operations. However, projections for 2010 chopping of another plant is a work in progress wherein one plant is seeing to shut mid-2010, either Birmingham or Solihull. Moreso, this is one way to cut the cost dramatically.

How do US elections differ from the Russian ones Term Paper

How do US elections differ from the Russian ones - Term Paper Example From this research it is clear that elections in the United States and Russia have their own unique features and characteristics that distinguish them from each other. Even though electoral processes share some similarities and characteristics, most contemporary democracies and jurisdictions have their own unique electoral systems that are protected by their constitutions. Most constitutions have detailed voting systems and arrangements that convert people’s votes into meaningful political decisions. The US has its own unique ways of dealing with election related issues, and, so does Russia. For example, in the United States, when the first round of elections does not produce a winner by absolute majority, the senate is given the power to elect the president. In Russia, when such a case occurs, a second round of elections between the candidates who had the most votes is held so as to determine the ultimate winner of the elections. These differences between elections in the US and Russia shall be the main focus of this research. In the United States, the system of government is the representative democracy, where representatives are elected by citizens to make government decisions on their behalf at different levels. In Russia, the constitution enshrines electoral laws that govern all election processes. The present study would focus on these differences between the elections in the US and Russia.

Financial markets and institutions Essay Example | Topics and Well Written Essays - 1500 words

Financial markets and institutions - Essay Example Any commodity market might be considered to be financial market if trader’s intention is not the immediate consumption of the commodity but as a means of delaying or accelerating consumption over time. Markets work by placing many interested sellers in one place, thus making them easier to find for potential buyers. An economy which relies primarily on connections between buyers and sellers to allot capital is known as a market economy. Financial markets are affected by forces of supply and demand, and allot capital over time through a price device such as the interest rate. Financial market could mean: organizations that facilitate the transaction in financial products, (for example, Stock exchanges facilitate the trade in stocks, bonds and warrants) and the coming together of buyers and sellers to trade financial products such as stocks and shares including: the use of stock exchanges; directly between buyers and sellers. There are different types of financial markets: capital market which provide finance through issuance of shares and bonds, commodity market which facilitate the trading of commodities, money market which arrange short term debt financing and investment, derivatives markets that provide instruments for the management of financial risk, insurance markets, which facilitate to cover of various risks and foreign exchange market which facilitate the trading of foreign exchange (Wikipedia, 2006).
