Global Warming Report Essay Example for Free

Global Warming Report Essay Over the past few decades scientist have been observing a warming trend in the over all temperature of the earth. Although the earth has been known to go through warm and cold periods, it seems that we humans are causing the earth to heat up this time. The greenhouse effect is causing the earth to go through this warming trend that we call global warming. The greenhouse effect is caused when the infrared radiation from the sun is absorbed in atmospheric gasses such as water vapor, carbon dioxide, ozone, and methane. All of these gasses escape slowly from the atmosphere, therefore the heat stays here longer in a short of warm airy blanket. Without the occurrence of the greenhouse effect scientist say that the earths average temperature would be around 30 degrees C. or 50 degrees F. There are many greenhouse gasses that can trap the infrared rays of the sun. Carbon dioxide can be released into the atmosphere in several ways, the bulk of it is produced by car exhaust, deforestation, and the burning of fossil fuels. It is a colorless, odorless, non flammable gas, and it is also the most prominent greenhouse gas in earths atmosphere. CO2 is recycled through the earths atmosphere using the process photosynthesis, which makes most life on earth possible. Another greenhouse gas is methane and it is one of the most common gasses in the universe. methane is colorless odorless gas that is lighter than air and is produced by organic decay. Deposits of methane can usually be found in areas where lots of natural decay takes place, such as swamps, and land fills. Each year we add 350-500 million tons of methane to the atmosphere through mining, raising livestock, rice cultivation, and landfills. In fact a cow can release up to a half pound of methane into the air everyday. Nitrous oxide is another colorless and greenhouse gas, however it does smell sweet. It is mostly used medically because it deadens pain, because of this it is called laughing gas. It is released naturally from oceans and by bacteria is soil. It is important to reduce our emissions because nitrous oxide we release today will still be trapped in the atmosphere 100 years from now. The set of greenhouse gasses are fluorocarbons, that is a general term for any group of synthetic organic compounds that have fluorine and carbon. These can be found in aerosol cans, refrigerators, and air conditioners. When fluorocarbons are released into the atmosphere they breakdown molecules of the earths ozone layer. The effects of global warming are also good for human beings, because it could increase food production. The most important factor in crop production is climate, and global warming would facilitate a better climate for the growth of more crops. It would also create much more space for businesses were there was once ice and harsh climate. Also without global warming the earth temperature would be about 30 degrees F. n average. With global warming there would be far fewer deaths from cold exposer. If global warming caused enough arctic melt then shippers would have many new shortcut routes to take from place to place. After glacier melt we would have access to many new mining areas. However global warming will also have some large negative effects. Such as health concerns, scientist predict that there will be ma ny more deaths from diseases that are irritated by heat, including heart attacks and heatstroke. Another downside to global warming is the amount of flooding that will occur with coastal cities. Scientist have predicted that about a sixth of the country will be under water after global warming has taken full effect. The Maldive Islands are a nation of 1190 islands that are home to over 200,000 people. These islands are only 1. 5 meters above sea level and if global warming occurs then all of those people will have to be relocated. There are many things that we as human beings can do to help prevent global warming from happening. We can start to take advantage of all the different types of renewable energy instead of burning fossil fuels that pollute the atmosphere in multiple ways. There are many types of clean, efficient, renewable energy sources. There are many energy sources that the earth has provided for us that we need to take advantage of. We need to build more wind turbines, hydro electric plants, and solar power plants. Another way of producing clean energy include using fission through nuclear power to create a clean renewable energy source. Government can also be doing there part by funding research about global warming and raising awareness about how individuals can be doing there part to reduce pollution. In conclusion, Global warming is a very serious thing, it can affect the orld in many different ways. We just need to decide which effects help or harm the world the most and then make an educated choice as to which ones the earth can handle while taking the least amount of stress, and having the best long term effect.

Essay example --

Most of Australians are affected by housing loans. 70% of homeowners buy a house in Australian through the housing mortgage loan. Due to the optimistic attitude of the general public about the economic situation, a lot of people buy houses for renting out to obtain stable income. In 2010, the Australian Government authorized the Australian Securities and Investment Commission (ASIC) to regulate exit fees that banks were seeking to impose. The exit fee is the payment that banks require customers to pay for permission to transfer their home loan to another bank, which considers the housing loan being one of the most important factors in exit fees or "terminate†. In an article of The Times, it was reported that an exit fee of $5,178 was charged if a loan of $300,000 was borrowed for 25 years and terminated within 3 years (Martin, 2010). Such an expensive exit fee makes high switching cost for the house loan takers, through which the bank may gain market forces. This article will discuss the switching costs in Australian home loan market and analyze how these switching costs may increase market forces of suppliers in these markets. In addition, this article tries to find out that after exit fees is changed according to the new regulations, what the changes of supplier cost will be and whether their profits will increase or decrease. Switching costs in Australian home loan market â€Å"Switching costs "was first presented by Michael †¢ Porter in 1980, referring to the one-off cost generated in the course of consumers transferring from one provider to another product or service provider. This cost includes not only economy expenses, but also time, energy and emotion, being an important factor of constituting barriers to enterpri... ...lly, the equilibrium is at point A (Q1, P1). With more rivalry and competition between suppliers, S1L shifts to the rights of S2L. The equilibrium point moves from point A to point B (Q2,P2) . As a result, loans price (interest rates) fall from Q1 to Q2 according to Graph 1. Profit is equal to total revenue of minus cost. While total revenue is equal to the price multiplied by the quantityï ¼Ë†price is decreaseï ¼â€°. It can be concluded that the Australian government to develop policies to protect the interests of local people through the intervention of good housing loan market. The Australian government's move to provide a variety of options for Australians, they can freely choose, while reducing the financial risks, the government provides loans to low-income persons through banks at below market rates, and they encourage healthy competition wwithin the home loan market.

I. INTEGRATED SCIENCE(Interaction: Environment and organism) II. COURSE PAPER: CASE STUDY Bacteria constitute a large domain of prokaryotic microorganisms. Typically a few micrometres in length, bacteria have a wide range of shapes, ranging from spheres to rods and spirals. Bacteria were among the first life forms to appear onEarth, and are present in most habitats on the planet, growing in soil, water, acidic hot springs, radioactive waste, and deep in the Earth’s crust, as well as in organic matter and the live bodies of plants and animals, providing outstanding examples of mutualism in the digestive tracts of humans, termites and cockroaches. On February 6, 2013, scientists reported that bacteria were found living in the cold and dark in a lake buried a half-mile deep under the ice in Antarctica. There are typically 40 million bacterial cells in a gram of soil and a million bacterial cells in a millilitre of fresh water; in all, there are approximately five nonillion (5Ãâ€"1030) bacteria on Earth, forming a biomass that exceeds that of all plants and animals. Bacteria are vital in recycling nutrients, with many steps in nutrient cycles depending on these organisms, such as the fixation of nitrogen from the atmosphere andputrefaction. In the biological communities surrounding hydrothermal vents and cold seeps, bacteria provide the nutrients needed to sustain life by converting dissolved compounds such as hydrogen sulphide and methane. Most bacteria have not been characterised, and only about half of the phyla of bacteria have species that can be grown in the laboratory. The study of bacteria is known as bacteriology, a branch ofmicrobiology. Most bacteria secrete a covering for themselves which we call a cell wall, However, bacterial cell walls are a totally different thing than the cell walls we talk about plants having. Bacterial cell walls do NOT contain cellulose like plant cell walls do. Bacterial cell walls are made mostly of a chemical called peptidoglycan (made of polypeptides bonded to modified sugars), but the amount and location of the peptidoglycan are different in the two possible types of cell walls, depending on the species of bacterium. Some antibiotics, like penicillin, inhibit the formation of the chemical cross linkages needed to make peptidoglycan. These antibiotics don’t outright kill the bacteria, but just stop them from being able to make more cell wall so they can grow. That’s why antibiotics must typically be taken for ten days until the bacteria, unable to grow, die of â€Å"old age†. If a person stops taking the antibiotic sooner, any living bacteria could start making peptidoglycan, grow, and reproduce. Bacteria were the most prominent creatures in the early stages of life’s history almost 4000 million years until 600 million years ago. Fossils called stromatolites can still be found and were made by Cyanobacteria. III.

CONTENT A. BRIEF PRESENTATION OF THE CASE Endogenous endophthalmitis is a potentially blinding ocular infection resulting from hematogenous spread from a remote primary source. The condition is relatively rare but may become more common as the number of chronically debilitated patients and the use of invasive procedures increase. Many etiologic organisms (gram-positive, gram-negative and fungal) have been reported to cause endogenous endophthalmitis. Risk factors are well defined and include most reasons for immune suppression. A high clinical suspicion is needed for early diagnosis and treatment. Early intravenous antibiotic therapy remains the cornerstone of treatment. The roles of intravitreal antibiotics and vitrectomy are evolving and may become more widely accepted as therapeutic modalities. The authors report a case of endogenous endophthalmitis and provide a brief review of the literature. Endogenous endophthalmitis is defined as an intraocular infection resulting from hematogenous bacterial spread. It is relatively rare, accounting for 2 to 8 percent of all cases of endophthalmitis, and is associated with immunocompromised states, debilitating diseases and invasive procedures.1 Because of the rapid advance of medical technology, a longer life span of patients with chronic diseases and a rising prevalence of long-term intravenous access, the disease may become more common in clinical practice. It is important that the family physician be aware of endogenous endophthalmitis because early diagnosis and prompt aggressive treatment are imperative if vision loss is to be avoided. B. POINT OF VIEW Banana bacterial (Xanthomonas) wilt, first detected in Uganda in 2001, has since spread rapidly. Approximately one third of Uganda’s banana growing land is now affected by the disease, which renders fruit inedible and ultimately kills the plant. The Ugandan government has been praised for its promptness in attempting to control the spread, but despite these efforts, and the encouraging success of control in some areas, the risk of further spread, both within and beyond Uganda, remains. Strengthening and refining the control effort is now clearly essential, but how should this be done, where are the research priorities, and what action should be taken by Uganda’s neighbours? In July this year an expert consultation of senior stakeholders from policy, research and disease control, was convened at the UK’s Central Science Laboratory near York. They offered New Agriculturist their points of view on the current status of the disease and the ways forward for control.

What the World Eats, by Peter Menzel - 1750 Words

Four people sit kneeling around a small table in a small room laden with food. A room where a serious man in a black box holds out a can of something altered and edible, and a young girl perched near her mother clutches a bag of potato chips to her chest as if claiming it as solely her own. This is the scene depicted in a photograph of the Ukita family in Kodaira City, Japan as part of a series taken by Peter Menzel for the book â€Å"What the World Eats†. This series of photographs illustrates not only what people eat in different parts of the world, but also how their families, and lives as fellow humans can so closely resemble our own. The Ukita family is kneeling around a small table in a small room. The extent of the food they’ve†¦show more content†¦But the presence of these foods is not necessarily the entire point of the image. It is true that Japan is currently the second largest packaged food market behind the United States, and is the third largest market for U.S. exports of food products such as red meats, processed fruits and vegetables, and snack foods (Japan country profile, 2011); however it is also true that Japan continues to be among the top ten countries with the lowest obesity rates with only 3.1% of people with a BMI over 30. Comparing this to the current obesity rate in the United States at 33.9% tells us that even if there has been an apparent increase of the consumption of junk food in Japan, the country is still not anywhere near partaking in the level of unhealthy eating seen in the U.S. (A spotlight on world obesity rates, 2013). As said by Naomichi Ishige in The Cambridge W orld History of Food, â€Å"Although there has been a rapid increase in the consumption of previously rare foods, such as meat, eggs, dairy products, and fats, the consumption of traditional foods, like fish and vegetables, has also increased.†(V.B.4-Japan, 2000). This is evident in the photograph of the Ukita family. Although there is a presence of unhealthy food in the form of the family’s chips and cake they are placed on the far edges of the image whereas the abundance of the family’s fish and vegetables areShow MoreRelatedWhat Families East in â€Å"Hungry Planet: What the World Eats.by Peter Menzel and Faith DAlusio1161 Words   |  5 PagesPeter Menzel and Faith D’Alusio conducted a photographic study of what families around the world eat during the course of one week.
