Examining Deforestation Of The Amazon Rainforest Environmental Sciences Essay

Examining Deforestation Of The Amazon Rainforest Environmental Sciences Essay The amazon Rainforest is one of the richest areas on Earth biodiversity wise and possesses many endemics species of fauna and flora. The Amazon also plays an human population has grown, and demands in soybeans, cattle and wood as increased over time, the Amazon rainforest has been selected for deforestation. Recent concerns have arisen over the last decades emphasizing the problems deforestation causes especially biologically. This problem has been further underlined as concerns over global climate change have arisen. The Amazon forest is the greatest tropical forest in size as it covers an area over seven million square kilometres and is found in ten countries of South America. Motives of deforestation, rates, history Most of the Amazon Basin ( >70%) is found in Brazil ; therefore most of our study will focus on the Brazilian Amazon. Starting in the late 1950s, for the purpose of developing the western and northern parts of Brazil many new roads were constructed which constituted a direct access to the Amazon tropical forest. The construction of these routes along with other incentives ( such as cattle ranching , hydro electric project, timber extraction) was aimed at expanding development and integrating the whole territory into the countrys economy. The program was successful as people moved along these large highways; for example 2 million people moved along the Belem-Brasilia in the first 20 years of its construction. The settlement along the major highways and within the Amazon forest was highly unorganized which led to long term unnoticed deforestation. Overtime the rates of deforestation have increased from the 1970s to the 2003-2004 and since then have decreased. The peak in 2002-2004 was the highest rate of forest clearing for a three year period: 52 670 km ² were cleared. The 2008-2009 area cleared totalizes for 7008 km ². The literature seems to agree on the motives for deforestation although the importance of small farmers in the process is debated . ( K.R Birby , P. Fearnside). The motives for deforestation are multiple: contrarily to common belief, the biggest reason behind clearing in cattle ranching secondly, is small farmer exploitation then, logging, and recently soybean and palm oil plantations have led to deforestation. The reason behind this hierarchy and cattle ranching as being the number one reason behind forest clearing is due to multiple state incentives. These incentives made cattle ranching one of the few profitable product to rise in the Amazon. Under the Brazilian law, clearing the land in order to install pasture is characterised as effective. (K.R Kirby). Cattle ranching is one of the most popular use of land in the Amazon as it is not a labour intensive job , by products can be used ( such as milk) , and it is produces offspring. Compared to crops, the main advantage of cattle ra nching is that cattle ranching are independent of weather conditions. Small farmers also play an important role in the clearing of the land as they apply slash and burn method in order to create fertile land to grow their crops on. As farmers need for more land, they continuously increase their property. K.R Kirby has calculated that on average a small farmer clears 1 ha of forest per year. Furthermore, tropical soils are not fertile and fail at the long term production of crops, thus after 2-3 years the land is unusable and new land has to be slashed and burned. Today as agricultural financing has been more readily available in the Amazon compared to other regions in Brazil, soybeans farmers are pushing to the North. As the price for soybean has increased, it has become one of the most profitable crops to plant in the Amazon. A large part of the soybean production is used for export (as foreign currency) therefore greatly encouraged by the state which even plans on building new roads and infrastructure in order to expand the production. Although not broadly mentioned in the literature, it is important to also underline the logging activities undergoing in the Amazon. JA Foley et al mention that the logging has recently been recognized as one major source of land change in the Amazon. Although selective logging is comparatively not as ecologically destructive as cattle grazing or pasture, it has been shown that logging destroyed the same amount of forest as the area cleared for other activities. Indeed, selective logging leaves behind a fraction of the natural forest and allows some natural regeneration; not completely destroying the ecosystem. Biodiversity effects: The clearing of thousands of km ² of land is not at any cost. The Amazon is one the worlds richest zone in terms of biodiversity and number of endemic species. Being one of the largest forests in the world the tropical Amazon forest constitutes an important carbon sink for the integrity of the planet. Scientists have become aware of the importance of conserving the forest because of the numerous ecosystem services it provides. It is difficult to understand and quantify the ecosystem services provided by an ecosystem. As Fearnside explains, it is complicated to put a value on an ecosystem service. An obvious way of calculating the value of the ecosystem is using the profit of the good produced in the given area. This method does not take into account the future damage that could occur due to the abuse of the ecosystem. Indeed we taking the example of forest clearing , we can use the value of the good which will be produced on the area cleared but on a large scale that value does not take into account the habitat destruction of species. Often times we put a price on ecosystem services in order to emphasize the urgency of taking conservation actions, putting fines on illegal land used. Based on the literature there are many ecosystem services provided by the Amazon rainforest. Namely the most important ecosystem services are carbon sequestering, water flow of the Amazon River, air circulation patterns, the spread of water borne disease , fires , invasion by exotic species and most importantly , and biodiversity loss. The clearing of Amazon might influence the hydrological regime of the area because the forest regulates the quantity of water flowing into the river as well as the nutrient content. The quantity of water increases greatly overall because there is no interception by plants leading to much more surface runoff and less percolation in the soil. Indeed it has been observed in the Tocantins river basin, the changes during the 30 years period (1960-1990) in land cover have led to an approximate 25% increase in the river discharge during the same period although there were no changes in the precipitation regime. Over the long term, scientists are worried that the evaporation budget will change so much as to change global patterns of air circulation. Vector-borne diseases increase due to the loss of vegetation and due to an increase in the number of mosquitoes (which are common vectors of diseases). Forested areas allow for more control of the disease though population control of infected animals, their hosts and intermediate disease vector. In South America, the most important disease transmitted by mosquitoes is malaria. A study in Peru has shown that Anopheles darling mosquito species are more susceptible to biting as the land cover decreases. The study found that when the area is deforestated by more than 20%, mosquitoes have a tendency to bit more than in forested areas. The reason for this increase is due to the preference of mosquitoes to breed in areas with shrubs or grasslands. ( A.M. Vittor) One of the most striking effects on deforestation is the loss of biodiversity. No papers truly estimated the loss of biodiversity due to deforestation. But based on the literature we can estimate the number of species potentially targeted by deforestation. The Brazilian Amazon is classified as one of the five megadiversity countries by the WWF (World Wild Fund) (P.Fearnside). Brazil has over 50  000 angiosperm plant species, over 400 species of mammals, over 1500 species of birds, over 500 species of amphibians, over 400 species of butterfly and over 70 species of reptiles. Deforestation can lead to changes in biodiversitys ecological niches, habitat fragmentation, or even invasion of exotic species. A major concern has arisen amongst ecologists due to the threat of deforestation on biodiversity hotspots. Indeed it has been observed in some cases that biodiversity hotpsots overlap the deforestation hotpsots. These latter are areas where deforestation occurs suddenly, locally and greatly pushed by demographic factors. The danger for the ecosystems when these two hotspots overlap is the extensive loss of habitat for the fauna and flora. Indeed, deforestation hotspots lead to much habitat fragmentation as many harvesters carry on their activity without much knowledge on the ecosystem and the implications of deforesting (Etter et al 2006). Moreover, it has been proven that a threshold exists for a species to survive. Species need enough area in order to reproduce and forage without it a population cannot sustain and is determined to extinguish. Much of the deforestation trends are not managed and very spontaneous, leading to patches of deforested land and often times the minimum thre shold is surpassed threatening the survival of many generations. As underlined in Etter et al., no significant studies have been consolidated in order to better understand the overlapping of deforestation and biodiversity hotspots; suggesting more data to be collected. Indeed without data there cannot be any consensus on the conversation policies to protect the Amazons ecosystem. Another paper also suggests the idea that better inventories should be complied in order to understand the forests composition and to better manage the area based on the species autoecology. Furthermore the paper underlines the importance of thorough and precise data entries with identical quantification measurements. These factors are all very important in the inventory process in order to build credible dataset on which policy makers can rely upon (Biscaia de Lacerda 2010). Deforestation in the context of Global Climate Change A major concern of the 21st century is the increase of carbon dioxide in the atmosphere and the consequences on the worlds biomes. The role of the Amazon forest in the global carbon cycle is storage of organic carbon in the soil or in plants. The process through which plants take in CO2 is photosynthesis storing it afterwards in the biomass under the form of leaves, branches, roots, flowers and other structural tree components. The destruction of the Amazon makes it an emitter of carbon rather than a sink. Indeed because of land cover changes, carbon is no longer stored. Per se, carbon is not emitted from the forest rather carbon is not taken up by the trees anymore resulting in a net surplus of CO2 levels in the atmosphere. Furthermore the necessary machinery used for deforestation as well as the by-products of wood and the processing of trees in factories also contribute to increased levels of carbon dioxide in the atmosphere. Some studies have tried to understand the changes which would occur if CO2 levels increased and deforestated areas kept increasing. The outcome results in many effects linked to changes in surface albedo, leaf area index, and surface roughness and texture (Compounding). In the study, the CO2 levels were doubled, increasing the CO2 concentration to 660 ppm. The IPCCs projection on CO2 levels project that 660 ppm will be reached by the end of the century under the least severe scenario: A1B which predicts: A future world of very rapid economic growth, low population growth and rapid introduction of new and more efficient technology. Major underlying themes are economic and cultural convergence and capacity building, with a substantial reduction in regional differences in per capita income. In this world, people pursue personal wealth rather than environmental quality. ( IPCC http://www.ipcc-data.org/ddc_co2.html). The sole effect of doubling CO2 concentration in the atmosphere results in a 2.6 T °C increase in temperature, increase in precipitation by 9.0 mm per month , and increase in -the net longwave radiation at the landsurface by 4.5 W m ­- ² subsequently increasing the surface evapotranspiration. There is not a great difference for all the factors when studying the present deforestation climate with the future warmed climate combined with deforestation, directly pointing to the fact that deforestation is the main source of deregulation in the climate (Figure 2). Indeed most changes due to increased CO2 levels are felt in the mid-high latitudes. Figure 2( Zhang et al.)

Mad Cow Disease in the United States :: MCD mad Cow disease US Essays

In March of 1996 the British beef industry was dealt an incredible blow when a European Union commission imposed a worldwide ban on the export of UK beef. The ban was imposed after an outbreak of mad cow disease (MCD) in Britain. MCD is the laymen term for Bovine Spongiform Encephalopathy (BSE), a disease that leads to deterioration of the brain tissue in beef and dairy cattle. It is the hypothesized link between MCD and Creutzfeldt Jakob Disease (CJD), the similar condition in humans, which led to the imposition of the export ban on British beef. This ban effectively crippled the UK beef export market in addition to sending a shock throughout Europe concerning beef safety. News of this ban spread throughout the world portraying images of infected cattle stumbling and falling unable to maintain their balance. While the scientific community was, at the time, unsure of the nature of the link between MCD and CJD, if any, the effects of the outbreak may have been much further reaching th an Europe. It is arguable that North America was also impacted to some extent, whether long term or short, by the MCD scares. In the days that followed the ban on UK beef, beef futures in Chicago fluctuated as traders were torn between two economic forces. The first was the expected increase in demand. Markets formerly serviced by UK beef must now be filled with beef from other countries. The second impact deals with the adverse effects the outbreak could have on consumer demand. North American consumers were also exposed to a great deal of media propaganda as most, if not all, North American newspapers and television news broadcasts, national and local, carried stories of the outbreak and the horrific consequences of CJD. If concerns of food safety in the United States and Canada were never of concern there would have been no need for the United States Department of Agriculture and Agriculture and Agri-Food Canada to issue statements testifying to the safety of each of the countries respective beef. This paper looks at the short-term impact of the MCD media propaganda on consumer demand for beef in the United States. Due to the fact that the supply of beef in the United States is completely risk free, or at very most extreme minimal risk, in terms of MCD and the risk to the beef supply, the scientific side of the story need not be considered.

Gun legislation in the United States

Gun legislation in the United States Children in the United States are considered to be endangered as more than 18,000 students under the age of 19 years are shot and killed by use of firearms each year (Lawrence Robert, 2006). These gunshot incidents are caused by family members, strangers, and even peers. It was also noted that thousands of youths and children use guns to commit suicide.Advertising We will write a custom essay sample on Gun legislation in the United States specifically for you for only $16.05 $11/page Learn More This has even proved to be the most successful way to commit suicide compared to other means. For most families, shooting in schools has left them living with fear that their children are no longer safe in the hands of school administration. Late last year, a student by the name Adam Lanza forced his way into an elementary school by the name Sandy Hook. Within five minutes, he had shot 154 bullets leaving 26 people dead by use of a Bushmaster 223- calibre rifle. This left the country so devastated with so many questions being asked by the parents. This led to various demonstrations being held across the United States protesting the burn of firearm use completely. Use of guns for perpetuating violence is not the major problem, violence among the youth is. Guns raise special attention because they are lethal and widely available to the youth thereby worsening youth violence. The major cause of injury and death is gun violence. It has caused serious communal and mental issues on youth, youngsters and even families in the society (Lawrence Robert, 2006). There are various factors that have contributed to gun violence in the United States especially among the youth and children. One such issue is the engagement in drug related issues among the youth. It is not only drug and substance abuse that causes gun violence among the youth in schools and societies at large. The youth are also seen to engage in drug dealings and street drug markets. Most of t hese drug dealings lead to the youths forming cartels that often end up in rivalry among the groups. The youth in these groups end up buying guns from illegal gun markets to be able to control the illegal drug market.Advertising Looking for essay on government? Let's see if we can help you! Get your first paper with 15% OFF Learn More The second factor that contributes to gun violence in the United States is the fact that guns are made available to the youth. Through the illegal gun markets, the youth are able to buy guns and used them anytime they feel threatened by the society around them (Alexander, 2003). Even where adults own guns, they fail to put adequate measures to ensure that the youth under their care are not able to access such lethal weapons. It therefore makes it hard for schools to control such youth as the youth themselves feel like they have overpowered the community around them. Illegal gangs in the United States are not an unfamiliar case. Each year more and more gangs are formed by the youth (Lawrence Robert, 2006). These gangs often cause insecurity in the society as most of them, if not all, possess guns illegally. These gangs often get involved in gun fights amongst themselves leading to serious injuries and even death among the youth. There has always been a public debate about how guns should be used appropriately in the society. The argument has concentrated on situations under which adults ought to own guns overseeing the youth (Stephens Nelson, 2007). The supporters of gun rights insist on the appropriate usage of guns for self-protection and athletic (Holly, 2008). They fail to propose that children and the youth should not access guns whatever the circumstance without the supervision of adults. Youth and children should be treated as a special case when it comes to law and public opinion regarding gun policy (Alexander, 2003). That way there will be a control measure put in place to ensure that there is r eduction in the number of youth able to access guns that cause danger to school children and staff. In order to address the gun violence issues in the United States, there should be strong relationship between levels of government and its branches. This is important for the delivery and administration of education services in the United States. Ministry of education must reduce its levels of bureaucracy by delegating operational aspects that are significant to lower governmental levels such as schools. In order for government’s policies to be effective, both by design and implementation, there should be a strong relationship between levels of government and their branches. Such relation is referred to as intergovernmental relation.Advertising We will write a custom essay sample on Gun legislation in the United States specifically for you for only $16.05 $11/page Learn More In terms of intergovernmental relation aspect, there are various aspects that should be considered in order to address gun violence in schools and communities. One such aspect is the government structure. Most countries hold a unitary form of government whereby the central government makes most decisions relating to its country’s issues (Holly, 2008). This is not a good system of administration as the government at the top does not understand the day to day situations that affect departments under it directly. There should be a decentralised system of government to allow for decision making at schools. This encourages efficiency among schools as it inspires liberal and democratic decisions among schools. Schools will hence be able to stream line their students whenever they are found to be going astray by administering punishment and counselling whenever necessary. In addition, the aspect of capacity that should be considered is building and accountability standards. These standards, especially in examinations, are left in the responsibility of state to determine the average expected standards of passing an examination. These high- stake exams do not consider underinvestment in various schools by the state as it could be a major cause of underperformance by some school. The underperformed schools could be lacking the right amounts of finances to be able to take up disciplinary measures for correcting school children. This is indeed an aspect that should be considered to be able to control the number of school dropouts and even be able to ensure that the school children and the youth are nurtured to produce well behaved persons in the society. Moreover, the aspect of intergovernmental relations and the financing of schools should also be considered. The state should ensure that equal amount of tax money is disbursed to finance the education of children regardless of where he or lives (Stephens Nelson, 2007). This step coupled with decentralization will ensure that schools not only use their funds to improve students’ perf ormance but also come up with programmes that improve the moral state of children and youth going through the education process. Schools will be able to budget effectively and be able to set aside funds for counselling students with special needs.Advertising Looking for essay on government? Let's see if we can help you! Get your first paper with 15% OFF Learn More The finally aspect to be considered is school- linked social- services coordination. Not only children in the United States but also children all over the world are faced by a multitude of contemporary problems. Such problems include; racism, family violence, substance abuse, unaffordable and inadequate housing, sexual promiscuity and child abuse. The services needed to react to these evils are normally fragmented across a number of uncoordinated government ministries and agencies (Stephens Nelson, 2007). It is therefore important for states to adopt policies that ensure external agencies and schools work together to address non-academic issues experienced by children and the youth in schools. Schools should also ensure a coordinated service linked to schools to develop new expectations by introducing new actors in the education system. One thing that generates barriers is the fact that there are professional and organizational variances among numerous government agencies and schoo ls. Such barriers include confidentiality issues, lack of a common outlook and even communication problem. In conclusion, gun legislation and policies must be amended in order to reduce the incidents of gun violence among the youth and children in schools. Very few gun violence prevention programs and policies involving the youth have been taken into consideration up to date (Holly, 2008). Policy makers should be encouraged to think widely as regards to gun policy to ensure that parents and children are no longer prone to dangers associated with gun violence and therefore live without fear. Coming up with the policies is not the only issue. The aspect of intergovernmental relation should also be taken into consideration if such policies are to remain effective in terms of implementation in the future. Without intergovernmental relation, there would be poor coordination and hence poor response in addressing the issues that affect schools and the community at large regarding gun viole nce among the youth and children in the society.

Astronomy and Renaissance essays

Astronomy and Renaissance essays The Renaissance was a time for reform. Renaissance, French for rebirth, describes the intellectual and economic changes that occurred in Europe from the fourteenth through the sixteenth centuries. During this time, Europe emerged from the economic decline of the Middle Ages and experienced a time of financial growth. Most importantly, the Renaissance was an age in which artistic, social, scientific, and political thought revolutionized. In the area of astrology, Renaissance scientists changed the ideas and theories that were familiar in the Middle Ages. Scientists such as Nicholas Copernicus (1473-1543), Tycho Brahe (1546-1601), Johannes Kepler (1571-1630), and Galileo Galilei (1564-1642) made new discoveries, introduced new instruments, and developed ideas that modernized Renaissance beliefs. During the Middle Ages and even going back to early Greek and Roman culture, it was believed that the earth was the center of the universe. The sun, moon, planets, and stars had two functions: first, motion in orbit around the fixed earth, and second, a participation in the daily rotation of the celestial sphere which produced our daily cycle of night and day (Cohen, 37). Before Galileo and Copernicus, there was the theory composed by an astronomer named Claudius Ptolemaeus known as Ptolemy (died 141 or 151 AD). He wrote a book, The Almagest, where he described and summarized most of ancient mans understanding of the universe. In detail, he describes the appearances of the stars and planets, and tried to explain how the universe was constructed and how it worked (Ptolemaic System, 2). This was later known as the Ptolemaic system. However, this system assured that the Earth stood still and was at the center of the universe. Aristotle (384-322 BC) supported the theory of an earth centered universe with laws of physics and philosophy. Aristotle was a student of Plato, founding his own school of Natural Philosoph...

Organizing for uncertainties in a dynamic market Assignment

Organizing for uncertainties in a dynamic market - Assignment Example The author further argues that dynamic environment provide the best opportunistic environment in the corporate world. However, dynamic environments need proper management since they are accompanied by many uncertainties. Many project portfolios fail due to dynamic environment. The article describes how dynamic environments can easily destroy a project portfolio. From the evidence provided in the article, one project out of five ventured in a dynamic environment have failed due to poor management. Coming up with project portfolios require a lot of consideration with the type environment a project location is based. The issue behind dynamic environment is the management of the uncertainties presented by this environment. In words by Yvan (2012) the richness in opportunities the dynamic environment presents are the same uncertainties resented by the same environment. Characteristics in a dynamic environment include high level of profits in one season while the fate of other financial ye ars is unknown. This uncertainty makes it essential to have programs and strategies to manage their project portfolio. To curb this problem the article involves the use of dynamics capabilities frameworks. These frameworks are aimed at studying project portfolios in dynamic environments. ... The dynamic capabilities frameworks are aimed to achieve three prospects: Provision of a better understanding on the management of projects facing uncertainties. Analyzing the relationship between the measures put in place by organizations to minimize the impact caused by uncertainties and the sources of uncertainty in dynamic environments. Provide recommendations and possible improvements in the standards and models of project portfolios. From the author of the article these three objectives can secure an organization’s assets in any case of an occurrence of an uncertainty. If the assets are not completely secured they effects of the uncertainties are also minimized. Project managers are therefore advised on how to ensure a proper implementation of the dynamic capabilities frameworks. In some cases these frameworks only involves means of insurance in any occurrence of risk. In the dynamic environment, the frameworks are more important since projects require total quality mana gement. According to Yvan (2012) the completion of projects depends mainly on the ability of the project manager to foresee the transition from and to each face of the project. This is made easier by the implementation of the dynamic capabilities framework. From the article, there are claims that project management in dynamic environments. Organization and project doing enough to ensure that project portfolio are being managed effectively. This is after many approaches have been developed. Do project managers have the intent of making projects suitable for the dynamic environment? Having successful projects portfolio also includes having proper organizing mechanisms in the organization. Proper organization mechanisms include the methods of

Art 123 Essay Example | Topics and Well Written Essays - 500 words

Art 123 - Essay Example The theme is naturalistic. There is a spirit of expectation. Masaccio modeled his figures as solid as statues to be realistic, by using strong light in particular areas to give shadow effect in his figures, complying with the principle of Renaissance along with naturalism. The featured background is done with linear perspective of mountains and temple structure that is drawn symmetrically. Renaissance artists, writers and thinkers are said to have respect for order, symmetry and proportion. In addition to this are the realistic facial expressions of the figures. For example, the face of St. Peter, in his effort to bend over and take the money away from the fish's mouth, has turned red. At the right side, the tax collector is illustrated with a satisfied expression on his face while St. Peter hands him over the coin. The actions, gestures and expressions here are what real people express in given circumstances. Figures are dressed in Greek's fashion, in line with the biblical description of dress code during the first century, with tunics tied at the waist, and cloaks wrapped over their left shoulder, around the back, and clasped at the front. On the other hand, Caravaggio's The Calling of St. Matthew is a Baroque art, as evident by the visual representation of the painting itself, using exaggerated position of the figures which is a principle of Baroque art.
