They thought ending a piece with major was more stable than ending with minor. Raced Dynamics Improvisation Ornamentation Polyphonic texture is emphasized Fugue is king Absolute music is emphasized Contrast highlighted Word painting Castrato Doctrine of Affections-Word Painting Word painting= music mirrors text It was accepted that music ought to arouse the emotions (affections) ex: Joy, anger, love, fear, exaltation An entire piece or movement was built on a single affection= The opening musical idea established the mood of the doctrine of affections piece, which prevailed until the works end.Renaissance = plain, simple Baroque = decorated When composers wrote their music down, they left a great deal up to the performer, who was expected to decorate the piece with ornaments. They were not Mitten down! Performers would improvise and show off their special skills and talents. Some example of ornamentation: rill- rapid movement between two neighboring pitches Tremolo- rapid movement between two far away pitches Grace Note- a very quick note that precedes the main note Strong emotions dramatic way. Contrast was also used to express strong emotions.Music No radios, cassettes, CDC Aristocrats had private concerts played by their own musicians ; Musicians Mere employed, they were servants Composers worked in a Church, or for aristocratic court They kept their Jobs as long as the employers were satisfied Working for the Court Composers at the court had the status similar to that of the head chef.

Acquainted with the Night by Robert Frost PR Essay Example
Acquainted with the Night by Robert Frost PR Essay Example Acquainted with the Night by Robert Frost PR Paper Acquainted with the Night by Robert Frost PR Paper Essay Topic: The Poetry of Robert Frost Hari Jani 2nd Period 10/29/13 Poetry Response The poem Acquainted with the Night by Robert Frost is about a person who feels isolated and depressed in their life but thinks everything is alright. The author discloses the isolation and depression the speaker is facing through the use of figurative language and tone. The title of the poem is an important part of the poem because it is repeated in the poem. The use of refrain in the first and last line notifies the reader of how important the title is to the poem; Acquainted refers to familiarity or experience the speaker has had with the Night or darkness; the speaker probably had an xperience or struggle with some form or darkness in their life. The title as well as words like rain, down, saddest, dropped, and cry impart a downhearted and melancholy tone throughout the poem. The author incorporates oodles of metaphors into the poem to depict the speakers thoughts and feelings. Night is an extended metaphor for the depression the speaker is inflicted with because it is the subject of the rest of the poem. The speaker has outwalked the furthest city light which is also a metaphor for depression and loneliness; the speaker is the cause of his solitariness because he alks into a distance himself, and the further he gets, the less light, or felicity he acquires. The metaphor for distance is also present when the speaker hears a cry from fa r away. The cry he heard from a horizon was not for him, and that brings about even more alienation and dejection. The luminary clock is a metaphor that compares a clock to the moon; the moon is not only the most distal thing in the poem to the speaker but also the radiant thing that reaches him when he is in duskiness. The author uses personification when he expresses time was neither wrong nor right. The time isnt actually right or wrong, but the speaker is in a state of limbo; he is lonely, grief-stricken, and vacuous but doesnt think there is anything amiss. The refrain, l have been one acquainted with the night implies that the speaker has no friends or family, and the have been insinuates that he has experienced this feeling more than once. The authors use of alliteration and rhythm grant the reader a better perception of the speakers actions. The consonant sounds in the line stood still and stooped the sound of feet give off the sound of footsteps; the rhythm of each line like I ight continues to escalate this sound. The rhyme scheme follows a certain pattern: ABA, BCB, CDC, DAD, and DD. This also amplifies the sound of feet walking. I find this poem to be quite depressing and sad. I sympathize with the person who is going through this dilemma, but I admonish them because they keep making the situation worse. If there is a problem, one should fix it instead of ignoring it and thinking nothing is wrong. IVe never been depresses or isolated, but I understand what a person going through that must feel like; the person is walking by themselves t night on a road that doesnt go anyn. vnere. There are probably a lot of people in the world who suffer from loneliness and woefulness. This poem teaches humans what not to do if they are inflicted with this dilemma. They shouldnt outwalk the furthest city light, or pass by the watchman. They should stay in the light to get help from a friend or a family member. This poem isnt nebulous about how the speaker handled this situation; he succumbed to his worriment. This gives people a paradigm of a person who was defeated by their problems, and they should look at this and do the exact opposite.

Effect of the exchange rates and inflation on the investment Statistics Project
Effect of the exchange rates and inflation on the investment - Statistics Project Example Further, the use of PPP will help in determining the effect of inflation rates on exchange rates in each of the two countries. The knowledge about the inflation rate will conclusively lead to comparison of the intensity of investment between the countries. Accessing the relationship between exchange rates, interest rates and inflation is essential in understanding the intensity of investment. The necessity of PPP theory in this project arises because it acknowledges the changing patterns of trade usually witnessed between two countries as the result of the difference in inflation rates. In order to achieve the objective of the project, the baseline is to analyse the change of exchange rates between UK and USA through testing the PPP theory. Data given for the quarter period will be used in performing regression in Minitab thereby giving information on the differences about the exchange rates. Intuitively, the basis of this project is that absolute form of PPP cannot be used because i t does not acknowledge the differences in prices thereby calling for the use of relative form. The project involves testing the relevance of PPP theory through a real life situation comparison of the exchange rate and inflation rate between UK (pound) and US (dollar) for the period of 10 years quarterly (from 2000 to 2009). Success in carrying out this test calls for perusing through the EIU database. In this case, US and UK were selected as the subjects for comparison followed by acknowledging the period of time as from 2000 to 2009.

Transition in Adolescent Development Essay Example | Topics and Well Written Essays - 500 words
Transition in Adolescent Development - Essay Example Many researchers have undoubtedly identified the decisive role of parents in moulding the character of their children during this transitional period. When a child is moving from primary to secondary, this is quite sure that he/she is subjected to various kinds of transitions that may affect him/her all through the life time. Therefore, regarding the parents and the teachers, they should be very vigilant and attentive in observing the transitions occurring to the children, and as such, the study of transition in adolescent development and schooling deserves greater significance. In order to examine adolescence in media, the paper seeks to gather material from Karen Thomasââ¬â¢ online article entitled: 12-14 Year-Olds: Transition in Adolescent Development & Schooling, published on Dec 1, 2010.

The corporation report Essay Example | Topics and Well Written Essays - 1000 words
The corporation report - Essay Example In addition, they have compared corporations to a football team in that all teammates play different parts yet have a similar goal (HAINES, 2007, P 8). Furthermore, corporation has being compared to a family unit and a telephone line. Overall, corporations are greedy and materialistic organizations that do not care about the welfare of the people. Examples of workers being paid slave wages and the use of chemicals to increase milk production at the expense of the animalââ¬â¢s health by Monsanto is proof (YouTube, 2013). Findings Argument for the Film The film talks about the negative side of corporations and produces enough evidence. For example, the Nike shoe company has been accused of hiring child labour in the third world countries. Another corporation is the Coca-Cola Company which continued to manufacture the beverage despite protests of water infections in India. These corporations exploit people (Fisse, & Braithwaite, 1993, P, 1). The child labour in the Nike Company is al so being paid slave wages. Monsanto insisted on the use of BST Posillac, which harms the, cow and the farmer too. Monsanto also polluted Vietnam with toxic herbicide that resulted to death and cancer. The documentary has listed some negativity of corporations. Continuous deceitfulness. Callous unconcern for others. Reckless disregard for safety of others. Failure to conform to social norms with respect to lawful behaviours. Incapacity to endure lasting relationships. Incapacity to experience guilt. Arguments against the Film Even though the documentary has majored on the down sides of corporations it has also shed light on the good sides of some corporations. Billionaires have given out their wealth in support of the environment, for example, Bill Gates and Sir Richard Branson. Monsanto has a number of claims to defend their position. The corporation claims the following. Protecting ecosystems while driving productivity. Innovating to improve lives. Delivering the best seeds for far mers. Looking globally to plant the best locally. In the top 10 of the Worldââ¬â¢s most innovative companies. Nike also claims the following. Providing safe working environments. Usage of ethically sound methods. Socially responsible sourcing practices. Burson-Marsteller corporation claims to aid people achieve good lives by; - Giving people a voice. Set up the national smokerââ¬â¢s alliance. Created BCFA to combat environmental campaigns. Legal Position of a Corporation ââ¬â UK Different countries have different legal positions of a corporation (Rosenau, 1997, P, 200). Companies Act 2006 is laws that restate the greater part of the enactments relating to companies (Degenhardt, 2010, 17). In the UK CA 2006 sets out the rules for reform of companies (Almond, 2013, P 191). In the company acts of the UK legal position states under Salomon v Salomon & Co Ltd [1897] A.C. 22 that a company has a separate legal personality. This means that a corporation Liability for its actions is limited to the company. It can sue and be sued, own property and enter into contracts. The EU transparency directive 2007 in the case of the Cadbury report 1992 and Hampel committee report 1998 addresses corporate fraud and accountability (Fisse, & Braithwaite, 1993, P, 2). Furthermore, it addresses conflict of interest and auditor independence or the white collar crime (Haines, 2007, P 9). Legal Position of a Corporation ââ¬â USA In the USA Corporations are now armed with constitutional

The Plastic Waste And Management Methods Environmental Sciences Essay
The Plastic Waste And Management Methods Environmental Sciences Essay This dissertation contributes new and unique evidence to the debates surrounding plastic waste management options and their effects on the environment. A recurring theme in the debates around plastic waste management system is the extent to that whether the plastic waste disposal options give genuine benefits to the environment. Often, criticizers of the strategy drive towards larger plastic recycling assert that the act of recycling could be in fact has less or no benefit to the environment, consuming extra energy in the collection and transportation of plastic waste to the recycling facilities than is saved by the procedure of recycling. In order to notify this debate in details, this dissertation commissioned a key international LCAs studies. By reviewing considerable international studies, and employing rigorous criteria to filter out those studies that have less robust methodology and assumptions, after the number of studies screened 11 state of the art LCAs were selected for methodical study, including disparate scenarios. The result is more objective oriented analysis of the environmental encounters of different waste management methods for Plastics waste than one single study can deliver. Through the use of past LCAs, it investigates both plastic waste disposal options and environmental effect of the activities of plastic waste management by using meta and statistical analytical methods. Research methodology also considered, setting up a framework to review and selection restricting criteria for LCA studies. In so doing it provides the waste management methods performances with regards to environmental indicators. Persuading plastic methods have been chosen to comparing options :Landfilling, recycling, incineration and pyrolysis performances with regards to perusing environmental impact indicators: climate change, depletion of natural resources, energy demands and water consumption. This dissertation focuses on recycling, incineration, landfilling and pyrolysis that are plastic waste disposal methods and their performance concerning climate change, depletion of natural resources, energy demand, and water consumption that are environmental impacts indicators. By reviewing past LCAs, it investigates plastic waste management options and environmental effect of the activities involved. For selection of LCA studies restricting selection criteria are developed. Meta analytical methods were adapted to synthesize and codify the findings of LCAs. Codified data were statistically analysed to calculate mean size effect. It provides the best, intermediately and the worst option concerning environmental performances of plastic waste management methods. The results are clear that all of the studies prop the following conclusions:. after comparison between of recycling, land filling, incineration and pyrolysis of waste plastic, Recycling appears to be a preferable management option over alternatives. Whereas, pyrolysis method emerged as a promising option for plastic waste disposal. INTRODUCTION This study grew from a meeting of two interests The authors academic interest in the environment and development issues, and work experience in the field of Polyethylene (PET) plastic. The main objective of this dissertation is is to contribute to the debate concerning the causes of environmental impacts of plastic waste management methods The following section introduces the background and significance of choosing this study area and context of the study. It also outlines the aim and objectives of the dissertation. Additionally, organisation of the whole study will be informed. Finally, justification of the undertakings the present study will be given. Plastics waste, need of a better waste management method and sustainability and plastic will be discussed. 1.1 Plastic waste and management methods Plastic is a durable, versatile material and relatively inexpensive. Plastic products have brought benefits to society in many ways such as quality of life, jobs, and economic activities. However, waste plastic also imposes environmental impacts. In view of the fact that plastic is non-biodegradable, it can remain in the atmosphere for a exceedingly long time and so plastic poses risks to the environment and human health, It is also difficult to reuse and/or recycle in practice (European Commission, 2013a). Many countries are trying to incorporate different strategies to increase plastic recycling rates. According to the Environmental agency (UK), statutory recycling targets have been given to all the local authorities in Wales (2012a). Whereas, in Scotland waste regulations operates without statutory recycling targets, and here funds are available for local authorities to help increase recycling rate(2012b). By making recycling mandatory or funding recycling a difference can be made to global environmental issue that exists because of waste. This dissertation focuses on recycling, incineration, landfilling and pyrolysis that are plastic waste disposal methods and their performance concerning climate change, depletion of natural resources, energy demand, and water consumption that are included as environmental impacts indicators. By using past LCAs findings, it investigates plastic waste disposal options and environmental effect of the activities involved in plastic waste management. 1.2 Aim and objectives of the study: The aim of this research dissertation is to identify environmentally sustainable management options for waste plastics. There will be an attempt to achieve the aim of this study by undertaking following three objectives. Objective 1: By reviewing, the relevant literature to address environmental issues related to the recycling, landfilling, pyrolysis and incineration. In addition to environmental indicators that are included in the study: climate change, depletion of natural resources, energy demand, and water consumption evaluating international processes to recommend the best legislation, policies and practices. Objective 2: Objective two is to set up a framework for LCA selections. Once LCA studies are retained Meta analytical methods will be applied to synthesize the findings of selected LCAs. Further, use of Meta synthesis for the codification of the LCA findings. Finally, statistically analysed the data to calculate mean effect size using Microsoft excel tool. In order to assess the environmental viability of recycling, landfilling, pyrolysis and incineration for waste plastics through appraisal of included environmental indicators. Objective 3: The presentation of the codified data sample will take place in this objective. Codified data will be statistically analysed using Microsoft excels (2010). To present in the form of histograms and charts, four management options will be assessed under each environmental indicator based on the results of each selected LCA study. To find out which one of the four waste management methods emerges as the best option regarding each or environmental indicator performances. 1.3 Justification of the study: Plastic waste management and its environmental implications are a majorly important issue and one of the major research topics of many governmental and environmental entities such as NAPCOR, DEFRA, WRAP, Recoup, Environmental Protection Agencies(EPAs) of majorities of countries and United Nation(UN). WRAP (2006) and Villanueva et al (2004). For instance,published a major preliminary environmental impact analysis of a different type of waste materials including plastic and comparison of recycling, incineration and land filling by reviewing international LCAs and the conclusion of that research is recycling offers more environmental benefits than alternatives. This research considered as high quality and information shared by UN and US EPA. However, there have been many waste management option emerged since WRAP report been published such as pyrolysis and gasification, Efw informs Jowit (2010). What is different in this study is the inclusion of pyrolysis, which as a new method was not included in WRAP (2006) and Villanueva et al (2004). Second gap that is addressed is the inclusion of one of the environmental indicators -water consumption in the impact studies, this indicator previously ignored by WRAP (2006) where the concentration is on Climate Change, Energy demand and Depletion of natural resources. To investigate and address these gaps the author will undertake past LCA studies. Findings of LCAs will present this in a new way. Additionally, the decision to use a meta- analysis approach originated from United Nations Development Program (UNDP) report on review of past LCA using Meta analysis (2012).however, LCA selecting criteria were not used in UNDP research, which is otherwise adopted in this present study to ensure quality of the result. This study will also try to find out whether recycling is environmentally, sustainable option for plastic waste as claimed by past studies or will emerging technologies will prove to be a better option. This report will also attempt to identify data gap in the literature review and recommend if there is a need for further research in the specific area for future researchers. 1.4 Organisation of the study: The research structure includes four sections. Firstly, Literature review section that will review the existing literature that is related to four waste management options, continuously building towards the significance of environmental sustainability of plastic waste management methods. Additionally, to give broader understanding of included environmental indicators will be studied. Review of international policies, legislation and measures that are pertaining to plastic waste management methods and environmental indicators.

LiTeRATURE REVIEW This section is an attempt to achieve the objective one. The following section divided into three parts, First section addresses plastic waste management methods: landfilling, recycling, pyrolysis and incineration. Secondly, environmental indicators: climate Change, depletion of natural resources, energy demands and water consumptions that are used in the study as a benchmarking to compare each waste management method performances. Finally, provides an overview of the international strategies and policies applied in practice. Key sources used for this study are reports of Government Agencies: WRAP, DEFRA and EU and internationally United Nations Environment Programme (UNEP) along with published international scientific databases and journals from Springer, International Journal of Life Cycle Assessment and ScienceDirect. This represents a combination of sources including Governmental Agencies and academic authors. In addition, the webpage of the European Commission was searched for studies commissioned as input to EU policies. Plastic waste problem description: Broulidakis Martà nez (2012) noted that waste is not treated as worthless garbage anymore, it is instead believed as a re. Nevertheless, what is happening with the resources? Treating waste sustainably is a crucial issue. Identifying whether or not waste is been managed in a way that is betterment for environment, society and it should be economical as well. This chapter will find an answer to those questions by reviewing already known literature. It will also try to identify which one is the known environmentally sustainable method for plastic waste by reviewing published articles, studies and set of research. It was stated by Tehrani et al., in 2009 that there is no a solitary knowledge of a single technology that can resolve the waste associated issues. In order to provide a broader understanding of this issue, following section will discuss the existing plastic waste management options to gain a better understanding of the processes related to waste management and their environmental effects. 2.1 Waste management methods and their environmental impacts The following section addresses methods that are in use for the management of plastic waste include Landfill, Incineration, Pyrolysis and Recycling along with their environmental impacts are discussed now in details. 2.1.1 Landfill A landfill is a one of the waste management methods in which solid wastes are disposed in a manner that limits their encounter on the environment. According to the Federation of Canadian Municipalities (FCM) Landfilling is the complex system of interrelated material and sub system that act together to break down and stabilize disposed waste overtime (2004). Landfill is extremely old disposal method, but yet one of the utilized one for Municipal Solid Waste (MSW) management. Apart from taking large area of land it also generate odour, bio-aerosols, visual disturbance and lead to the release of hazardous chemicals through the leachate which is the liquid that drains or leaches from a landfill sites. Emission of greenhouse gas through landfill is due to organic breakdown of disposal of biodegradable including bio plastic waste. European Union Low informed in 2008s issue on the management of bio-waste in the EU countries that Landfill of waste usually entails non-recoverable loss of resources and land. Since landfill, sites can normally not be used after closure for scientific engineering and/or health risk reasons and in the medium to long term. This review of literature found that landfilling is not considered a sustainable waste management solution. 2.1.2 Incineration Incineration is a significant method that avoids the problem of landfilling space problems. In this method, thermal waste treatment procedure takes place where raw or unprocessed plastics waste can be utilized as feedstock. Plastic waste is combusted in different temperature according to the type of plastic and in this period plastic waste modified to carbon dioxide, water and non-combustible materials alongside solid residue state leaves incinerator bottom ash (IBA) that always has contain a small amount of carbon residual (DEFRA, 2012). Published report of the Environment Agency (2002) on the safety of incinerator ash confirms that IBA can be safely used as an aggregate in construction as it contains dioxin levels similar to those found in soils. However, friends of earth review reports argued that the government should give guidance on acceptable contamination levels in construction materials (2002). International Journal of Environment in Comparative study of municipal solid wast e treatment technologies using life cycle assessment method stated that incineration as one of the competent strategies to resolve waste association problems (Zaman, 2010) and its ability to generate heat and energy from the plastic waste. However, considering incineration of plastic waste is solely depending on whether or not energy is recovered (Weiss et.al ,2012)along with other aspects such as quality of fuel and efficiency of energy which varies considerably depending on whether incineration plant delivers electricity, heat or both along with the used technology, for instance, higher efficiencies can be achieved in fuel gas condensation method. However, according to the EUs report (2010) on waste management, the environmental impacts of incinerating plastic waste included greenhouse gas emissions. Furthermore, Pilz, et al. (2010) in their report on The impact of plastics on life cycle energy consumption and greenhouse gas emission in Europe informed that in some circumstances, incineration of plastic waste in MSW can result in a net increase in CO2 emissions. It is certain that this process can be helpful in avoided some of the plastic waste problems, but it also has environmental impacts. 2.1.3 Pyrolysis Pyrolysis is an advanced thermal treatment. Interest in pyrolysis has heightened over the past decade, and there is considerable anticipation that this technology will prove to be viable alternatives for dealing with residual fractions municipal waste to assist in compliance with the Landfill diversion elements of the EC Landfill Directive (DEFRA, 2004). Pyrolysis is the thermal degradation of waste in the absence of air to produce gas, diesel like pyrolysis oil) or solid (mainly ash, char, and carbon). Zhiru (2001) pointed out difference in pyrolysis oil and diesel and noted that diesel cannot be assumed compatible with pyrolysis fuels (p.80) and remarkably few reports related to the behaviour of materials in pyrolysis fuels are available. Findings of research by Alston and Arnold (2011) informs that pyrolysis is a strong compromise method as compared to Landfill, Recycling and Incineration with their environmental impact categories. As the gases and oil produced in pyrolysis could be used as fuel and so provides significant resource saving without high impact on climate or landfill space. Additionally, Scheirs and Kaminsky (2006) noted, the main advantage of pyrolysis is that allows process of plastic waste which is otherwise difficult to recycle. This process produces reusable products with unlimited market acceptance (p24). This book is helpful in understanding pyrolysis process. However, does not assess environmental impacts of pyrolysis, nevertheless, it has been noted that unlike incineration, there are no environmentally harmful emissions in pyrolysis process (p.598). 2.1.4 Recycling Recycling is considered as one of the classic goals in sustainable waste management system (Bohma et, al 2010). Collected waste plastic are being sent to various market ,due to growing market for recycled plastics which includes closed loop systems for PET bottles. Plastics are also exported to abroad for recycling purpose (Defra, 2012), but it is argued environmental benefits of export overshadow the impact of transportation. Environmental impacts of transportation involved in exportation are high. Recycling can prevent an enormous amount of virgin production, which leads to saving energy, depletion of raw material, reducing GHG emissions including acidification even after considering transportation. However, WRAP (2006) argued that, The accurate impacts are depending on the virgin material being replaced and life span of replaced product. PET is one of the plastics types which is collected the most for recycling (DEFRA,2011b) this type of plastic is been included in the present stu dy. Recycling protects resources embodied in waste plastic however, it is argued by many about the requirement of energy inputs for the transformation process, this lead to environmental impacts. Besides that, not all of plastic types can be recycled. The PET bottle has strong advantages in recycling, however, complex products like composites, low weight articles or those that are contaminated with other products are less favourable to recycling. 2.2 Health impacts of plastic waste recycling There is a risk involved in plastic waste recycling affecting local populations in countries with less rigorous regulations than in the EU (Mudgal et.al 2010). Wong et.al noted that the majority of the cases companies fail to provide appropriate facilities protecting the environment and human health (2007). Such as chipping and melting of plastics in unventilated areas that are not seen in European practice can have negative consequences on human health. One specific case study showed due to incomplete combustion of Waste Electrical, and Electronic Equipment(WEEE) from plastic materials such as PVC and plastic chips there was higher concentrations of heavy metal found in the air of the China (Guiyu region). The study showed high concentrations of Polybrominated Diphenyl Ethers (PDBEs) in the air, released from the melting of polymers that contain brominated flame-retardants. Admittedly, National Institute of Environmental Health Sciences of America have informed that high exposure to PDBEs, which found in the human body, has been linked to, hormone disruption, thyroid permanent learning and memory impairment, behavioural changes, hearing deficits, fatal malformations and possibly cancer (Herbstman et al., 2010). However, human toxicity issue is ignored by environmental impact studies those are based on qualitative studies and the same confirmed by Wollny and European Environmental Bureau (EEB) Brussels(2013) 2.3 Environmental Impacts Indicators The following table explains each of indicators that are included in this study; it also critically analyse policies and measures taken to prevent environmental impact. Indicator Description of Environmental Indictor Description, impact and related worldwide policies Climate Change Climate change is also addressed as globe warming. Globe warming is the rise in the average temperature of the earth surface, due to a possible rise in the greenhouse impacts, provoked by anthropogenic emissions of greenhouse gases. Research published in the journal PLoS Medicine (2012) informs according to a group of European public health experts that climate change could alter patterns of food availability, physical activity and in some cases might bring direct physical harm. Friends of Earth (2007) reported that waste prevention is the most beneficial option from a climate point of view, followed by reuse and recycling; Warhorse and Watson confirm (2006) landfill and incineration are the worse options (p.6) The United Nations Framework Convention on Climate Change (UNFCC, 2013) an international treaty joined by 195 countries, except America. To follow up from Kyoto protocol green house gas emission is seen as the most crucial issue within the field of climate change policies. BBC informed back in 2009 that The America accounts for almost 25% of the worlds total CO2 emission and have received a large amount of criticism for its stance on climate change. Depletion of natural resources Resource depletion described as the cutting potential of all natural resources. The resources believed in this study are mineral and fossil resources. Plastics are made from oil, coal and gas, which are limited natural resources (Australia EPA,2013).majority of plastic bags are made from polyethylene, made up of natural gas, and Plastic is not biodegradable, so all the plastic that has ever been made is stilexist around us today. Most of it is in landfills, if not then floating in the sea. University of Cambridges report on plastic recycling informed that the production of 1 kg of polyethylene (PET or LDPE), requires the equivalent of 2 kg of oil for energy and raw material. Although plastics only consume around 4% of the worlds oil, supplies are becoming depleted. Once depleted these resources cannot be replaced. The depletion of natural resources is becoming a key focus(Karen,2008) This is evident in the UNs Agenda 21 Section 2 which provides the necessary steps to be taken by all countries to sustain their natural resources (2002) Schilling chiang confirms the depletion of natural resources is a sustainable development issue (2011).furthermore, Salvati and Marco (2008) noted in regards to natural resources, depletion is of concern for sustainability as it poses the ability to degrade current environments(p.218) and potential to impact the needs of future generations(p.523) Energy demand Primary energy is obtainable raw energy in nature and is separated into renewable and nonà ¢Ã¢â ¬Ã renewable primary energies. The non renewable are: atomic energy, usual gas, coal, and oil, Renewable is wind energy, solar, biomass and hydraulic. UK department of Energy and Climate Change (2012) informed that the UK has developed Pathways analysis and calculator tool which will help policy makers. Gervet (2007) in his captivating report on the use of crude oil in plastic making contributing to the global warming pointed out that energy consumption in total worldwide plastic production from 1939 till 2004 is 0.59 10 14 kWh (p.5). Plastics Europe informed in order to produce plastic products, energy resources are consumed(2013). Currently energy resources are majorly obtained from non-renewable sources, and when used; greenhouse gas (GHG) emissions are produced. Nevertheless, it was established in a study undertaken by GUA/denkstatt in 2004/2005 even more energy would be consumed along with more GHG emission, if plastic products were to be substituted by alternative materials. [Pilz et al., 2005]. Water consumption Water consumption symbolizes to the removal of water from the various origins (rivers, seas, and groundwater) for use by humans. This water is not returned to the origins and sources. According to the UN World Development Report, up to 500 Million Tons of wastes accumulate each year from Industry; most of it goes into the fresh water supply. Also informed some of the developing countries dump 70 % of industrial waste into untreated waters where drinking water gets polluted (2013). Professor Grossman noted back in 2004 that Industrial water use is about 22 %. According to Centre for Science and environment- India, countries all over the world set standards and target for water consumption for industries. China, For instance government push companies to save as much as 6 billion cubic meters of water per year informed in China water conservation Agency report in 2005. Proposed and implemented governmental strategies and policies targeting plastic waste will be discussed in details in the following part of this chapter. 2.4 Policies on plastic waste Plastic waste management goes across a numerous policy fields: along with sustainable management of resources and habitat protection, climate change, agriculture, soil protection and energy, biodiversity. Purpose of this section is to provide an overview of measures taken by Government agencies and environmental protection bodies to reduce the environmental impacts of plastic waste.According to Science for environmental policies ,European commission, (2011) Municipal waste collection and separation is a vital part in all waste management methods, for countries such as Germany, Austria and Sweden where waste management systems are more advanced, and source separated collection rates are already high(Waste Management World, 2013 b).waste management world (2013) reported European Union as the most advanced waste management system. The European exports of plastic waste rose by 250%, reaching 2.27 million tonnes approximately 5 million tonnes are annually recycled in Europe. Some selected counters, policies and measures related to the waste management are discussed in following table Country and Government Agency Introduced, Implemented Policies, Legislation and measures Netherlands Dutch Waste Management Association (DWMA) The Netherland recycle no less than 64% of its waste and the remainder are incinerated with generation of electricity, and a small percentage ends up in landfill. This is a country that is practically unique when consider recycling. Separating waste is the popular environmental measure activity among Dutch people that account for more than 90% of Dutch people involved in this sort of activities.

The Great Depression in America Essay -- essays research papers
à à à à à The Great Depression was a huge economic downfall in North America and involved many other industrialized countries of the world. The Depression began in 1929 and lasted for about ten years. Millions of people lost their jobs along with many businesses going bankrupt. The common misconception of the Great Depression is people think that the stock market crash was the main cause for it. There were many causes for the Depression; unequal distribution of money during the 1920ââ¬â¢s was the main cause of the Depression. This unequal distribution happened on many different classes of people. The imbalance of money is what created such an unstable economy. The stock market was doing much worse than people thought during this period. This lead to the biggest stock market crash in our history. The misdistribution of wealth and the stock market crash caused the economy to plummet (Modern). à à à à à The stock market was bigger than ever in the 1920ââ¬â¢s. Prices reached levels that people never dreamed of. At one point when the market was roaring in September 1929 forty percent of stock market values were pure air. This meant that investors thought that the stock market would go up because it had been going up. By 1928 and 1929 the Federal Reserve was worried about the high level that the stock market had reached (Galbraith 116). The Federal Reserve feared that the stock market might burst suddenly. If this did happen investment might fall, parts of the stock market might not be able to pay back debts, and even worse recession might result (Galbraith 118). The Federal Reserve in 1928 tried to make borrowing money for stock speculation more difficult and very costly by raising interest rates. All of the options that the Reserve tried had unfavorable risks associated with them. Many economists believed that the Federal Reserve was responsible for the recessi on. The stock market did crash on October 29 1929. The Federal Reserve tried to do to much to stop the recession and in return brought on the recession that they were trying to stop (America). à à à à à When the stock market crashed in October this day was known as ââ¬Å"Black Tuesday.â⬠On this day Americans saw their stocks lose a tenth of their value. The exact reason for why the stock market busted on this day are unknown (Delong 1). The stock market cras... ...t of 1935, which raised personal income taxes on the highest income levels (America). à à à à à On December 8, 1941 the U.S. Senate issued a declaration of war on Japan. Germany declared war on the United States on December 11, 1941. Industrial factories were at first slow to convert into making military machinery. By 1942, 33 percent of the economy was devoted to the war effort (Modern). This gave society a sense of patriotism and devotion to oneââ¬â¢s country. Between 1941 and 1945 the United States spent about $250 million a day in order to defeat their enemies. Federal spending was more than $320 billion over that period. That was two times as much money as the federal government had spent in its entire history up until that point. This government spending stimulated an industrial boom and stopped unemployment. By the end of the war in 1945, the farmerââ¬â¢s income had more than doubled. Corporate profits rose by 70 percent and the wages of the employees increased by over 50 percent. The most interesting statistic was that the earnings of the botto m fifth of workers rose to 68 percent. The Great Depression soon came to an end being swept away by the war (America).
