THE WITCHES COVE Essays - , Term Papers, Research Papers
THE WITCHES' COVE It was a dark, foggy night. Nothing was stirring, not even a bat. As I walked down the dark street to my friend's house, I saw the old broken-down, tattered Nelson mansion. As I passed the spooky old house, it seemed like a silence fell over the little town of Hallowville. A bone-chilling wave of cold passed through me as I noticed there was a single light burning in the attic of the abandoned house. As my eyes were glued to the glowing attic window, a dark figure passed by the dirty, cracked window. I shivered and begain to walk faster. Suddenly, a ghose-like figure jumped from the bushes and clamped an icy hand over my trembling mouth. The deformed figure roughly began dragging my body, paralyzed with fear, through the wet grass and mud towards the old house. When we reached the front porch, the old wooden stairs squeaked under us and I detected a bitter stench coming from beneath the broken planks of wood. As the front door was pushed open, it creaked on the rusty hinges and I immediately heard moaning voices coming from inside. As my limp body was dragged down a hallway, a musty smell seeped into my nostrils. Suddenly I was dropped on the floor and found myself alone in the dark. I cautiously got to my feet, tested out my wobbling legs and started to inch down the long, dark passage. Suddenly a screeching creature appeared in the air from nowhere, wrapped itself around my face and bared it's sharp fangs at my terrified eyes. I threw it off and ran blindly down the corridor. In the darkness, I did not see the wall that I plunged into face first. As I leaned against the wall, it began to turn, taking me with it int o the darkness. A chilly breeze passed over me and I shivered in the cold. As my eyes adapted to the darkness, I could see a white figure in the corner of the room. I slowly inched my way towards it. Suddenly the white figure lunged towards me, with it's mouth wide open. I clawed at the head of the object and as I made contact with it's face, it disappeared into the darkness. Several moaning voices suddenly encircled me, coming closer and closer until they were joined by the deafening sound of a chain saw engine. Having regained my senses and filled with the determination to escape, I looked wildly around the room. I spotted a faint light in the direction of the moving wall. I screamed at the top of my lungs and lunged toward the light, entering the narrow passage I had come through earlier. I again felt the cold rush of icy air as I passed through the exit and as I ran down the corridor, the smell of musty dirt penetrated my lungs. I reached the front door, flew down the broken front stairs and out into the night. I was finally free! I didn't stop running until I reached the corner where I found my friend standing. She had seen my escape from the house and questioned what I had been doing there. As we walked, she told me all the legends about the Witches' Cove house. I didn't share my entire story with her that night and don't plan to ever reveal everything that went on in the house. Still to this day, I can't be sure if what happened was real, but I will keep my secret and make sure I never pass by that house again.

Inbreeding Depression
Inbreeding Depression Free Online Research Papers There is currently 1.5 to 1.8 million species in the world that have been successfully named and classified. Of this number a vast amount already has, or is in the process of extinction. Loss of habitat, over-exploitation of wildlife for commercial purposes, the introduction of harmful exotic species, environmental pollution, and the spread of diseases pose serious threats to the worldââ¬â¢s biological heritage. This is of key concern as the removal of a single species can set off a chain reaction in the ecosystem affecting many others. This is especially true for keystone species, whose loss can transform or undermine the ecological processes or fundamentally change the species composition of the wildlife community. (U.S Fish And WildLife Service, 2005)Is there a method in which these species can be saved from extinction and reintroduced into the wildlife? A zoological garden shortened to zoo, is an institution in which animals are exhibited in captivity. In addition to providing visitors with an entertaining spectacle, modern zoos are also involved with conservation biology (PA, 2005). Conservation biology is the scientific study of the nature and status of the earthââ¬â¢s biodiversity with the aim of protecting species, their habitats, and ecosystems from excessive rates of extinction (Soule, 1986). Zoos meet there conservation role through captive breeding, the process of raising plants or animals in controlled conditions to produce stock for release into the wild, education, research, animal welfare, environmental enrichment, reintroduction and support for in situ conservation of species (F, 2008). Despite many efforts being made into conserving species, there are however some major cons traints faced by zoos in meeting their conservation role while at the same time providing opportunities for the public to learn more about and enjoy nature in artificial forms. One major constraint faced by zoos, is the cost and time to conserve some species. Large species breed at a much slower rates than other species and undergo seasonal breeding and require extensive fostering. An average cost of 1 million dollars in the USA is needed per year/per zoo. Therefore zoos require continued funds by tourism, and other methods in order to keep these species conserved. Other consequences arise within species themselves. Species that are kept conserved in zoos for a long period of time, result in a loss of behaviour in the wildlife, and essentially the species become adapted to zoo life. Species that have been kept in zoos for a long period of time, are in the habit of extensive care and nourishment, and therefore become adapted to living in a predator free environment. However, when let out into the wild, these species have no experience in searching for food and avoiding predators therefore natural selection will select for these traits that are advantageous in captivity, but deleterious in the wild population. A major approach that is taken to conserve an endangered species is inbreeding, which is breeding between closely related species, most often a result of population bottleneck. This is a major comeback for conservation as inbreeding often results to -inbreeding depression which is a reduction in the species fitness, and eventually leads to reductions in genetic variability. In a population where inbreeding occurs most offsprings will have recessive deleterious traits and these traits will be masked by heterozygosity, and so natural selection will select against heterozygoteââ¬â¢s. (Lynch, 2005) Inbreeding depression is a major consequence of captive breeding, as seen in species such as Lion population, South China Tiger, and the California Condor. These are just a few out of the numerous numbers of endangered species, which have undergone captive breeding and have been made an attempt at to keep conserved in the wildlife population. In order to illustrate the detrimental effects of Inbreeding depression, Packer et al, 1990 examined the declining lion population in Ngorongoro Crater which is an extinct volcanic caldera located at the western edge of the Gregory Rift. The lion population estimated to be at about 60 to 75 individuals over the period 1957-1961. In 1962 however, the lion population suffered an extraordinary outbreak of Stomoxys calcitrans biting flies that reduced the population to about nine females and one male. (C.Packer, 1991) Because of the drastic reduction in population size, there was extensive inbreeding amongst the survivor species. As examined by Packer et al, 1990 Ngorongoro Crater was largely repopulated by descendents of a group of four females. Each successive cohort of cubs belonging to these four females subsequently became established breeders and mated with only seven breeding males that immigrated to the Crater all during the period shortly after the outbreak. However once the sur viving females had bred successfully, the large coalitions of males prevented any further immigration which further increased inbreeding and therefore levels of heterozygosity subsequently declined by 10 percent. With a decline in levels of heterozygosity there is evidence that shows impaired reproduction in the Crater lions and higher proportion of abnormal sperm, which reduces sperm quality such that it penetrates female eggs at a very low rate. As a result productivity of the Crate population has declined since the 1970ââ¬â¢s and as predicted the average levels of heterozygosity in this population will continue to decline in the future in the absence of any male immigration. A similar study of a lion species named Panthera Leo, abundant in Africa suffered population bottle neck due to loss of habitat. (Bjorklund, 2003) And this resulted in reduced genetic diversity which is correlated with reduction in survival. This results in a higher population decline and can increase the rate of extinction. Therefore, as demonstrated by Packer et al, and Bjorklund et al, reduction in population size of a species promotes inbreeding which causes a decline in genetic diversity, and ultimately has detrimental effects on the species. Inbreeding depression has also been observed in the South China tiger, by study done by (Y.C. et al, 2007). The South China Tiger (Panthera Tigris Amoyensis) is a subspecies of tiger native to forests of southern China. Of the currently present 5 tiger species, the South China Tiger is the rarest and the most critically endangered due to factors including hunting, poaching and habitat loss. However one of the most serious threats to tigerââ¬â¢s survival is the use of tiger products in traditional Chinese medicines. The tiger bone is considered to be one of the most valued as a treatment to various conditions. (Tilson, 1997) Due to these factors the individuals declined from a reputed number of 4000 species in 1950ââ¬â¢s and continued to decline until the mid 1990ââ¬â¢s when the number of free ranging species was estimated to be fewer than 20 individuals(Gilson et al.2004). In the 1950ââ¬â¢s however four females and two males were captured from the wild and were used to fo und a captive population. (Y.C.Xu, 2007). Because of the vast decrease in population number, the 6 founder population were enforced to inbreed in the 1970ââ¬â¢s and continues to inbreed because of comeback such as their mating behaviour. Female tigers can only mate when they reach maturity at 3 years of age and only in temperate climates seasonally. Because of this only a small number of tigers are able to breed in each generation which lead to inbreeding depression in 1972. As observed by (Y.C.XU et al, 2007) inbreeding depression in the population shows low level of juvenile survivorship due to the loss of genetic variation and because of this infants were not able to adjust to the changing environmental conditions. Also because of low fertility and fecundity, reproductive difficulties were observed amongst the species. As a result the small number of founders and inbreeding depression contribute to a major challenge of conserving the South China Tiger. Inbreeding depression has also occurred in the wild population of the California Condor that ranged from British Columbia to Baja California in the 19th century (Vickey, 2000). During that time period, the species faced dramatic population decline caused by high mortality rates due to exploitation, habitat destruction and the most prominent factor lead poisoning. It wasnââ¬â¢t until the 1987, that all the remaining population of 27 individuals of which 14 were males and 13 are females were captured and brought into captivity. (Phillip, 1995) Due to the small population size, there was extensive inbreeding which led to the loss of genetic variation and changes in allele frequency. The population also harvested a vast amount of deleterious recessive alleles, which are usually depleted of the population by natural selection. Before the decline in the Condor population there is much genetic variability, and therefore recessive deleterious alleles are hidden from natural selection by d ominant alleles. However when the population declined, and inbreeding was enforced, close relatives that mate one another likely carry the same recessive deleterious alleles. Accordingly when relatives mate the offspring may inherit two copies of the same recessive deleterious allele expressing it. According to the study conducted by (Ralls et al. 1999), captive flocks had produced five deformed embryos that exhibited Chondrodystrophy, and died near the time of hatching. Chondrodystrophy, a recessive deleterious allele in chickens, is a condition where the abnormal development of cartilage affects bone growth before birth, and eventually leads to dwarfism. Chondrodystrophy in birds can be caused by a variety of factors such as mycoplasma infections and dietary deficiencies, particularly of manganese. (Ralls et al. 1999). Therefore inbreeding depression exposes Chondrodystrophy in offsprings, which results in a high mortality rate and ultimately reduction in population and stability of species extinction. Other species that are affected by recessive deleterious alleles caused by inbreeding are Golden Lion Tamarinââ¬â¢s (Leontopithecus rosalia rosalia). According to study done by (Bush et al. 1996), Golden Lion Tamarinââ¬â¢s are native to the forests of Brazil and are widely endangered with a captive population originating in 1982 due to extensive deforestation. The current captive population of 494 individuals underwent inbreeding, which resulted Diaphragmatic defects, a disease caused by recessive deleterious alleles. A diaphragmatic defect is a rare syndrome characterized mainly by a defect in the diaphragm that allows some of the abdominal organs to move into the chest cavity, and involved missing or formation of abnormal bones in the arms or legs. (M., 1980) Therefore inbreeding depression was observable in the Lion population and posed major consequences. As seen in the California Condor and Golden Lion Tamarin, low genetic diversity caused by reduction in population will result in inbreeding depression. This will unmask of recessive deleterious alleles in the offsprings of the parental generation, and will result in the depletion of these individuals due to natural selection. Today, more species are alive on the planet than ever before. Estimates place the number of species between 10 to 100 million, with only 1.5 to 1.8 million identified with Latin names (Lacy, 1997). Of this number studies indicate that 2 to 3 species are going extinct yearly due to a wide number of reasons such as exploitation, habitat destruction, pollution, global warming, introduction of exotic species, and the spread of diseases. Why should we initially care about species going extinct? Major concern isnââ¬â¢t about extinction of a single species, but rather the ecosystem it belongs to, and the interaction with other species. Some species play a vital role in there ecosystem, that if lost due to extinction, it could affect a numerous number of species. Zoos across the world now hold a major role in conserving these species. Species that are headed towards extinction are captured from the wild and placed in zoos in which they are provided an artificial habitat much like their ow n. With the rather small population of species, professionals employ captive breeding amongst them. It is the process of capturing animals from the wild and mating them in captivity in order to increase the number of species under protected conditions. (Waugh, 1988) Despite many species that have been reintroduced into the wild as a result of captive breeding, there is a downfall. Firstly, captive breeding programs focuses only on a few charismatic endangered species, and neglects the numerous number of other species that are in the process of extinction. It is also very costly to train individuals to capture species from the wild, and provide them with their mimicry habitat and other resources they require. A major consequence faced by conservation however, is inbreeding depression seen in species that mate relatives, or siblings. Major consequences of Inbreeding depression are seen in the Lion population, South China Tiger, and California Condor. Because of their relatively small population due to factors such as habitat destruction, these species were captured from the wild, and had gone through inbreeding. A major consequence of inbreeding is the reduction in fitness and the loss of genetic diversity. As the closely related species kept on inbreeding within themselves, it was only those alleles that were being expressed. With a loss of genetic diversity, offsprings of those individuals are not able to withstand the changing environment. Other consequences of inbreeding seen in California Condor, is the expressivity of a recessive deleterious allele. The offsprings exhibited diseases caused by these recessive alleles. Hence, when a population undergoes a bottleneck affect, most zoos try a technique commonly knows as inbreeding to try and preserve a species. Inbreeding also has its consequences as it is apparent in the three species discussed above. The most direct effect of inbreeding is inbreeding depression as it causes a reduction in population number.

Baggie Chemistry Experiments
Baggie Chemistry Experiments Overview An ordinary ziploc bag can unlock a world of interest in chemistry and in the reactions within and around us. In this project, safe materials are mixed to change colors and produce bubbles, heat, gas, and odor. Explore endothermic and exothermic chemical reactions and help students develop skills in observation, experimentation, and inference. These activities are targeted for students in grade 3, 4, and 5, although they may also be used for higher grade levels. Objectives The purpose is to generate student interest in chemistry. Students will observe, experiment, and learn to draw inferences. Materials These quantities are suitable for a group of 30 students to perform each activity 2-3 times: 5-6 plastic ziploc-style bags per lab group5-6 clear plastic vials or test tubes (may be used instead of baggies)1 gallon bromothymol blue indicator 10-ml graduated cylinders, one per lab groupteaspoons, 1-2 per lab group3 pounds calcium chloride (CaCl2, from chemical supply house or from store selling this type of road salt or laundry aid)1-1/2 pounds sodium bicarbonate (NaHCO3, baking soda) Activities Explain to the students that they will be performing chemical reactions, making observations about the results of these reactions, and then designing their own experiments to explain their observations and test hypotheses that they develop. It may be helpful to review the steps of the scientific method. First, direct the students to spend 5-10 minutes exploring the lab materials using all of their senses except taste. Have them write down their observations regarding the way the chemicals look and smell and feel, etc.Have the students explore what happens when the chemicals are mixed in baggies or test tubes. Demonstrate how to level a teaspoon and measure using a graduated cylinder so that students can record how much of a substance is used. For example, a student could mix a teaspoon of sodium bicarbonate with 10 ml of bromothymol blue solution. What happens? How does this compare with the results of mixing a teaspoon of calcium chloride with 10 ml of indicator? What if a teaspoon of each solid and the indicator are mixed? Students should record what they mixed, including quantities, the time involved to see a reaction (warn them that everything will happen very fast!), the color, temperature, odor, or bubbles involved... anything they can record. There should be observations such as:Gets hot Gets coldTurns yellowTurns greenTurns blueProduces gasShow students how these observations can be written down to describe rudimentary chemical reactions. For example, calcium chloride bromothymol blue indicator heat. Have the students write out reactions for their mixtures.Next, students can design experiments to test hypotheses they develop. What do they expect to happen when quantities are changed? What would happen if two components are mixed before a third is added? Ask them to use their imagination.Discuss what happened and go over the meanings of the results.

A New Empirical Model for Predicting the Sound Absorption of Polyfelt Article
A New Empirical Model for Predicting the Sound Absorption of Polyfelt Fibrous Materials for Acoustical Applications - Article Example Empirical models do not require detailed knowledge of the internal structure of the material nor are they derived from theoretical considerations. Delany and Bazley [1] showed that the values of the characteristic acoustic impedance and propagation coefficient for a range of fibrous materials, normalized as a function of frequency divided by flow resistivity could be presented as simple power law functions. Model for Impedance The model is based on numerous impedance tube measurements and is good for determining the bulk acoustic properties at frequencies higher than 250 Hz, but not at low frequencies [2,3]. The validity of this model for lower and higher frequencies was further extended by Bies and Hansen [4].Dunn and Davern [5] calculated new regression coefficients between characteristic acoustic impedance and propagation coefficient for low airflow resistivity values of polyurethane foams and multilayer absorbers. To that effect, engineers can obtain the absorption coefficient of sound at normal incidence by using the equation below: ZR = P0 * C0 (1 + C1 ((P0f)/r)-c2) The final model which comes as a derivative of the first model is Zt = (ZR + iZl)[coth(a + iB) * l] Zt = ZIR + iZIl Qunli [6] later extended this work to cover a wider range of flow resistivity values by considering porous plastic open-cell foams.Miki [7, 8] generalized the empirical models developed by Delany and Bazley for the characteristics acoustic impedance and propagation coefficient of porous materials with respect to the porosity, tortuosity, and the pore shape factor ratio. Moreover, he showed that the real part of surface impedance computed by the Delanyââ¬â¢s model converges to negative values at low frequencies. Therefore, he modified the model to give it real positive values even in wider frequency ranges. Other empirical models include those of Allard and Champoux [9]. These models are based on the assumption that the thermal effects are dependent on frequency. The models wor k well for low frequencies. The Voronina model [10] is another simple model that is based on the porosity of a material. This model uses the average pore diameter, frequency and porosity of the material for defining the acoustical characteristics of the material. Voronina [11] further extended the empirical model developed for porous materials with rigid frame and high porosity, and compared it with that of Attenborough's theory. A significant agreement was found between their empirical model and Attenborough's theoretical model. Recently, Gardner et al. [12] implemented a specific empirical model using neural networks for polyurethane foams with easily measured airflow resistivity. The algorithm embedded in the neural networks substitutes the usual power-law relations. The phenomenological models are based on the essential physics of acoustic propagation in a porous medium such as their universal features and how these can be captured in a model [13]. Biot [14] established the theo retical explanation of saturated porous materials as equivalent homogeneous materials. His model is believed to be the most accurate and detailed description till now. Among the significant refinement made to Biot theory, Johnson et al. [15] gave an interpolation formula for ââ¬Å"Dynamic tortuosityâ⬠of the medium based on limiting behavior at zero and infinite frequency. The dynamic tortuosity employed by Johnson et al. is equivalent to the structure factor introduced by Zwikker and Kosten [16] and therefore

Discuss the Careers of Teaching and Car Salesman Research Paper
Discuss the Careers of Teaching and Car Salesman - Research Paper Example I do have the panache to learn about the unique features of each model and brand I come across (Witkin 152). Should I be a car salesman, I will definitely be one who is quiet well informed about cars. Every good vocation begins with a deep interest, isnââ¬â¢t it (Bloom 26)? Besides, I am a very authentic talker and I do believe that anybody who comes to me with the intention of buying a car will certainly end up buying one (Andrews 247). I believe that sincerity and frankness are the ultimate credentials that make a good salesman (Shetty & Buehler 63). The other thing is that I am really good with numbers; however I really donââ¬â¢t know whether I will be able to convert my deftness and finesse with numbers into actual sales. One enticing factor is that if I end up being a great car salesman, at a later stage I can start my own car dealership. Pecuniary benefits do constitute an integral component of a great career. Well, one cannot expect to be a premium salesman right from th e start. Or perhaps, considering my astute skills and communication expertise, I can later on move to a career in real estate. Actually, the thing is that the more I ponder about a career in auto sales, the less convinced I feel about joining this profession. I should listen to my heart also. I think a career as a teacher will be the one that will do ample justice to my academic achievements and personal temperament. I do have the dedication to pursue a discipline with sincerity and dedication. One cannot teach what one does not know. In teaching a person needs to be proficient in the subject one teaches (Stronge 66). Besides, I have an academic bent of mind which continually nudges me to build on the understanding of the subjects I like (Aylett 75). Teaching will be a really suitable outlet for such academic dedication and sincerity. The other great personal attribute that supports my choice of teaching as a

Causes And Effects Of Deforestation In Myanmar Environmental Sciences Essay
Causes And Effects Of Deforestation In Myanmar Environmental Sciences Essay According to the Food and Agriculture Organization of the United Nations U.N.FAO, there are about 31,773,000 ha hectares or 48.3 of forests in Myanmar. An average of 372,250 ha or 0.95% of forest have been lost annually between 1990 and 2010. The organization states that within the period of 20 years (1990-2010), around 7,445,000 ha or 19.0% of the total forest has been cleared in Myanmar. Myanmar is one of the top ten countries that are happening highest deforestation rate in the world, and its rank is seven. The Rangoon-based Biodiversity and Nature Conservation Association (BANCA) alerts that Myanmar is meeting a deforestation crisis because of natural disasters (hurricanes, floods, drought and fires), human activities (logging, slash-and-burn agriculture, cutting trees for fuel, mining operations, dam building, clearing land for livestock grazing and oil extraction) and overpopulation. If deforestation cannot be controlled by government, the result could be very disastrous. It has negative impacts on environmental degradation and direct biodiversity loss. Exporting timber and human population are the main causes of deforestation in Myanmar. The Global Witness Non-Governmental Organization (NGO) manipulated that Myanmar shipped at least one million cubic meters of timber into China in 2002. Between 2010 and 2011, government exported 864,000 metric tons of timber and got US$600 million from it. Moreover, according to the UN FAO report that Burmas rural populations of around 70% or at least 30 million rely on forests for their basic needs in 2009. Government and people do not aware if they cut a lot of trees for their profits; it will affect on ecosystem and happen a lot of natural disaster in Myanmar. The purpose of this paper is to show causes and effects of deforestation in Myanmar. In particular, the impact of climate changes is very serious problem in Myanmar due to deforestation. This paper will discuss the plans of government to solve these problems ,and it will also provide some possible suggestions to protect the forests. 1.0 Causes The meaning of deforestation is cutting, clearing and removing of trees for various reasons such as logging, slashing-and-burning agriculture, clearing land for livestock, building dam. Sometimes, natural disasters can extremely destruct forests. For instance, Cyclone Nargis destroyed a lot of trees in Myanmar on 2 and 3 May 2008. Myanmar is developing country, so the government and people are extremely depend on forests. They cut down a lot of trees for various reasons, but the main point is for short-term economic benefits (Putatunda, 2011). Deforestation can be caused not only human activities, but also natural disasters. In Myanmar, government exports a lot of natural resources to other countries, but they got more money by exporting timber. According to the parliamentary Natural Resources and Environment Conservation Committee, Myanmar exports a lot of teaks by legal or illegal. The London-based Environment Investigation Agency claims that Myanmar exported 1.6 million tones of teak per annually to neighboring countries such as India, China, Bangladesh, Thailand and Malaysia. http://www.itto.int/files/user/mis/mis%20charts%20homepage/snap20111201.gif The agency states Myanmar got $5.7 billion by exporting 18 million cubic meters of wood log between 2000 and 2010. According to statistics, Myanmar has more than 16.32 million hectares of forest, and the area of teak is 24,300 hectares while the area of hardwood is 324,000 hectares. In Myanmar almost 1.98 million cubic meters of hardwood and 283,000 cubic meters of teak are used in Myanmar per annual. As a result, cutting a lot of trees for exporting is threatening Myanmar forests. Overpopulation affect on forests because they destroy a lot of trees for their profit. In Myanmar, the population is increased approximately one million annually. The population Myanmar is 54,584,650 in 2012 .According to UNFAO, 70 percent of the Myanmar people live in rural area, and they rely on forests for their basic needs and sustenance and income. Similar to Indonesia, people who get less than US$ 1 cut trees to get a few income for short-term (Stolle, 2008). Deforestation can be caused by not only man-made, but also natural disasters. In Myanmar, forest fire is one of the main problems to destroy forests. Myanmar lost up to 10 tons of forest fuel because of forest fire. As a result, every 30 to 70 tons of top forest soil are destroyed in Myanmar. Myanmar is facing natural disasters such as cyclones, landslides, earthquakes, tsunami, fire and drought. They are also real threats to Myanmars environment. Effects Burning trees and clearing forest extremely affect on environment. A lot of greenhouse gases including carbon dioxide are emitted from deforestation. Hence, the temperature of global is rising, so climate changes and soil erosion happen in Myanmar. 2.1 Climate Changes A lot of natural disasters are threatening Myanmars forest such as cyclones, earthquakes and floods (Moe, 2009). Cyclone Nargis destroyed trees and livelihood of people more than earthquake and floods. Cyclone Nargis was the top deadliest and most caustic tropical cyclones to ever strike Myanmar (The New York Time, 2012). The cyclone notably affected a total of 37 townships. The UN predicts more than 2.4 million people were affected by Cyclone. According to official figures, 53,800 were missing, and 84,500 people were killed. It also destroyed a million acres of rice paddies, trees and killed three-fourths of the livestock with its seawater surges. 2.2 Soil erosion and soil fertility loss In Myanmar, soil erosion is one of the most serious problems, and government cannot be controlled until now, so the agricultural products of Myanmar are falling. The fertility of the soil will reduce if the surface soil is eroded, and it can turn agricultural land into desert land. To prevent soil erosion, Myanmar should preserve forests and grasslands. If soil erosion cannot be preserved, it will lead to flooding. Weather and agricultural experts argue that they get 4 inches of rain from the flood areas, but flooding problems never happen with this amount of rainfall in the past. Not only nutrient depletion but also ecological, social and economic problem can be happened because of soil erosion. Solutions A lot of natural disasters are threatening people in Myanmar. Most disasters are caused by deforestation. So, the government are trying to reduce deforestation. They have three plans for that. First of all, they will completely ban exporting timber to other countries in 2014 (William Boot, 2012). However, it is difficult to stop illegal logging and exporting to China. The reason is Chinas border is very close with northern part of Myanmar. Most poor indigenous people are relying on forest for their basic need. Although the government does not allow to cut trees, they may do continue, but their strategic is a few positive effects on stopping illegal logging and exporting to not only China but also other countries. The second is reforestation. Every June or July, the government order to plant trees in the whole country. Moreover, the government has dictated its citizen between the ages of 11 and 60 must plant five trees per annually in China. The government mentions that the result of their program is they have been planted at least one billion trees since 1982. Although the government of Chinas plan succeed, in Myanmar, their programme failed since after planting trees, nobody care about them. In the peoples mind, their responsibility is just planting trees. The last strategy is collaboration with UN organization . It established The National Commission for Environment Affairs(NCEA) which purpose is to support the environmental protection and reduce the environmental degradation. The government expects this collaboration can prevent deforestation in Myanmar. The best solution is giving job to poor people. If they have enough money for their basic need, they will not destroy the forests. They will not care how many disasters happen and the government announces the rules because money is more important than retaining the environment for them. Furthermore, recycling and reusing items are also the best solution. For example, industries are using a lot of bamboo to produce paper. If people and students reuse the recycling paper, they may reduce using bamboo. These solutions may decline deforestation in Myanmar. Conclusion In conclusion, Myanmar was covered a lot of forests in the past, but nowadays, the coverage of forests decreased significanly in Myanmar. Exporting teaks and overpopulation are the main causes to be facing deforestation in Myanmar. Myanmar is poor country, so government budget depend on exporting teaks to other countries. Nearly 283,000 cubic meters of teak and 1,98 0,000 cubic meters of hardwood are used for exporting in Myanmar per year. Increasing population is also the main problem. Approximately one million people are incresing per annually. Most of them are poor, so they rely on forests for their basic needs. The result of destroying forests is emitting a lot of greenhouse gases. As a result the temperature is rising, and it affects on climate and soil of Myanmar. By changing climate, a lot of natural disasters are happening in Myanmar such as Cyclone Nargis, earthquakes, floods and drought. Cyclone Nargis destroyed a lot of trees and affected more than 2.4 million people, and it was nightmare for people. Myanmar has no many good place for agriculture due to deforestation. Government tried to solve deforestation , but it did not affect on the problem. Reducing unemployments and recycling items may prevent destroying the forests. If the government cannot control deforestaionthe, a lot of extreme natural disasters will occur in Myanmar. If there is no enough trees, the temperature will be higher and higher, and the death rate of people will sharply increase in hot season. Health problems and economy problems will also happen.
