Pros And Cons Of Mcdonalds Essay -- essays research papers

McDonalds: Welcome sign in the high street or a place to avoid? In this essay I will be discussing the pros and cons of fast foods. Now a day every body will recognize the golden arches of McDonalds, it is hard not to. McDonalds has restaurants everywhere, beside major roads and in almost every high street. Their commercials are on television at least once a day. They became popular within a couple of years. Teenagers especially like McDonalds because of the relaxed atmosphere, cheap prizes and the fact that all over the world you know what you are buying. In restaurants I find that the waiter there look at me and think that I might not be able to pay for the meal. With McDonalds I find that every person is welcome to come in and eat, no matter what you look like or how much money you have. There is also not a certain dress code that you have to oblige to. Fast food is easy to eat food that requires no cutlery. The fast food industry is not only good. The foods contain too much fat, salt and sugars. The food is not always what is said to be and uses a lot of packaging. Packaging that will be thrown on the ground, if the food is not eaten within the restaurant. People usually don’t take the time to throw the packaging in the dustbins. The high streets usually have a whole carpet with litter of fast food restaurants. I think that the restaurants can’t be responsible for the litter but the restaurants can do every thing to make their packaging as environmental friendly. Peo...

Individual Project problem A firm uses three machines in the manufacturing of three products: Each unit of product 1 requires three hours on machine 1, two hours on machine 2 and one hour on machine 3.Each unit of product 2 requires four hours on machine 1, one hour on machine 2 and three hours on machine 3. Each unit of product 3 requires two hours on machine 1, two hours on machine 2 and two hours on machine 3. The contribution margin of the three products is ? 30, ? 40 and ? 35 per unit, respectively. Available for scheduling are: 90 hours of machine 1 time; 54 hours of machine 2 time; and 93 hours of machine 3 time.

Essay on The Gaia Hypothesis - 1960 Words

The Gaia Hypothesis The Gaia Hypothesis is a hypothesis that was developed by James Lovelock and Lynn Margulis in the late 1970s. James Lovelock is a British scientist, an atmospheric chemist, and also an inventor with an education in human physiology. Lynn Margulis was a microbiologist during the 1970s at Boston University. She also originated the theory of the eukaryotic cell arising as a result of endosymbiotic cell capture. This theory is the one that gave her the credibility to advance the Gaia Hypothesis. Since every hypothesis takes the form of an if/then statement, the Gaia Hypothesis namely is an if/then statement. Summarized the Gaia Hypothesis is If life regulates the physical and chemical environment of the†¦show more content†¦This specific metaphor was originated by Lewis Thomas, a medical doctor. (Oceans, p.2). James W. Kirchner, a scientist, believes that this hypothesis can be compared to the writing of Shakespeare. Shakespeare stated that, All the worlds a stage, an d the Gaia Hypothesis states that, All the world is a living organism. (Oceans, p.2). Kirchner believes that metaphors inspire fruitful speculation, but that metaphors themselves are untestable. Lovelock has a separate metaphor for Gaia. Lovelock states that he sees Gaia as being like a tree. A tree that quietly exists, never moving except to sway in the wind, yet endlessly conversing with the sunlight and the soil. Using sunlight and water and nutrient minerals to grow and change. (Charlton, p.2). Another metaphor for Gaia is that it has been seen to be like a California Redwood. The redwoods tissue is 97% dead. The trunk has a thin layer of living organisms spread across its surface, and this is similar to the earths lithosphere. The bark is seen to be like the Earths atmosphere. The atmosphere is the protective coating on the Earth. The atmosphere protects the Earth like the bark protects the tree. The bark, like the atmosphere, allows the transfer of important gas ses, such as oxygen and carbon dioxide. While much of the Earth may be considered non-living, the fact that all of these non-living parts are involved to some extent in livingShow MoreRelatedThe Gaia Hypothesis Essay1295 Words   |  6 PagesThe Gaia Hypothesis In the early 1960s, James Lovelock was invited by NASA to participate in the scientific research for evidence of life on Mars. His job was to design instruments, capable of detecting the presence of life, which could be sent on a spacecraft to Mars. This led him to think about what constitutes life, and how it can be detected. He decided that the most general characteristic of life was that it takes in energy and matter and discards waste productsRead More Gaia: Argument over a single word Essay2082 Words   |  9 PagesGaia: Argument over a single word THESIS: Life on earth has been considered by some as a purposeful interaction tending toward ecological stability. However, when the scientific community led by James Lovelock tried to match this concept with science, it was (and continues to be) a dilemma. Introduction Whenever one hears the word Gaia, he or she will also hear life, goddess, purpose, ecology, and undoubtedly controversy. Not many topics have provoked more controversy among the scientificRead MoreEssay on The Vanishing Face of Gaia3403 Words   |  14 PagesReference: Lovelock, James, The Vanishing Face of Gaia A Final Warning, Allen Lane an imprint of Penguin Books, London, England.2009, 178 pages.

The resilience strategy is to live with not against the natural systems, and to understand the fluctuations of the natural world(Timmerman, n.d). As the Gaia hypothesis suggest, the Earth is a maternal, and self regulating platform, in which organisms function( Timmerman, 2009). In contrast, the Medea hypothesis articulates that the Earth is not as fond of life as Gaiist believe, and that our history is a collection of extinctions and massive ecological disasters on a planetaryRead MoreThe Lively Earth: Important Features Make the Earth Unique2753 Words   |  12 Pagesincoming from the sun. This reduction of solar radiation lowers down the atmospheric temperature dramatically which allows organisms to survive. The Earth would not be so unique among the solar system when missing either one of the systems. The Gaia hypothesis links this concept and indicates the Earth is a giant self-regulating system. The interactions of the organisms with their abiotic environments modified the condition of the Earth such as oxygen content and atmospheric temperature, making theRead MoreEnvironmental Science Worksheet Essay990 Words   |  4 Pages 2011, Ch. 4). 4. How do principles of system theory apply to the Earth as a living system? Explain interactions between humans and natural ecosystems. The system theory and especially the Gaia Hypothesis see the Earth as a living system. According to this hypothesis, life changes the environment for the continuation of life. Hence the conclusion is the Earth can achieve physiological self†regulation. The principles of the system theory can be summed as follows: systems respondRead MoreSecular and Religious Approaches to Environment Issues1949 Words   |  8 Pagesthing to do. However, he does not back this up with his reason. The last of the secular approaches that I am going to use is James Lovelocks’ Gaia Hypothesis. He believed in eco-holism – all ecosystems and living things are interdependent. The Gaia hypothesis challenges the view that humans are the most important species. He looked at the world through Gaia – Earth from space. What he saw was a self-regulating system – almost like a living being.

The result is that more heat is trapped in the system, increasing the global temperature by 1 ° C (about 1.8 ° F). Because the earth is a closed system, these issues are of major concern to environmentalists. As the â€Å"Gaia Hypothesis† states it, we are sustained by a single living system, meaning that we rely on it for our survival, in which all the parts are interconnected and everything we do affects it globally. For instance, as more heat is trapped in the atmosphere,Read MoreRawls Justice Is Fairness1030 Words   |  5 Pagessecond principle gives a reason for this, in that an inequality is permitted if the authorizing society will make this inequality available to everyone.
