Nuclear Energy Essay -- Renewable Energy

Nuclear Energy Energy consumption has become a necessity and an important part of our daily life in the past 10 years. It seems that the world is looking for an energy source that is cleaner, cheaper and more efficient and since nuclear energy has emerged it has become the forerunner for alternative energy sources. ‘As of 2004, nuclear power provided 6.5% of the world's energy and 15.7% of the world's electricity, with the U.S., France, and Japan together accounting for 57% of nuclear generated electricity’ (‘Nuclear energy facts’ 2007). Nuclear energy can be a doubled edged sword as it can be used for peaceful uses or used to manufacture weapons of mass destruction which can put the world in danger. As more countries begin to use nuclear energy, especially in the Middle East, fears of the countries in the west increases as they cannot be sure if their intentions are for peaceful uses or military uses. Many people argue that the main problem with nuclear power plants is the radioactive waste it leaves behind which have no use. ‘A typical nuclear power plant in a year generates 20 metric tons of used nuclear fuel. The nuclear industry generates a total of about 2,300 metric tons of used fuel per year’ (‘Nuclear Waste: Amounts and On-Site Storage’). There are mainly two types of radioactive wastes, low-level waste and high level waste. Low level wastes are ordinary items that come in contact with some radiation and are generated anywhere radioisotopes are used or produced such as a hospital. High level waste is the actual spent fuel, or the residual waste from reprocessing spent fuel. It takes ten of thousands of year for this for this waste to decay and be harmless to the environment, so it needs professional han... ...in the wrong hands it may lead to wars and disasters. If it is used properly, it can be an efficient source of energy in the future, treat and diagnose diseases and most important of all prevent wars.

Both tasks the two men set out to achieve are things never done before and include overcoming the power of nature. Victor, challenges death, trying to create a new being, and Walton tries to challenge the elements to reach to pole. Victor finds first, that doing this can only bring destruction, ‘the ever varied powers of nature’, a warning that it is too powerful to challenge. This warning, he then passes onto Walton who realises the peril he faces, and abandons his exploration. The â€Å"Ancient Mariner† was a poem written around this time by Coleridge. Coleridge was a Romantic, as was Shelley’s husband, and poems like this one were popular as this portrayed the types of things people were thinking about around that time. Mary Shelley may have been influenced by this poem about the theme of challenging nature as the poem also talks of this. It also included a ‘frightful fiend’ similar to the Frankenstein’s creature. Nature is also linked into another theme of loneliness both of the monster and Victor. The creature tries to tell Victor how he has been rejected and is totally alone saying things such as ‘I see bliss from which I alone am irrevocably excluded’ and ‘alone miserably’. The creature’s isolation could be found as a reason for his crimes as he never had anyone who he could interact with so he has never learnt how to do it, the creature’s isolation therefore leads to destruction. Every time the creature tries to make friends he is pushed further and further into isolation until he is in the most isolated place on earth, the North Pole. Using the vast open snowy mountains as the creature inhabits allows the feeling of only him being there and no one else being anywhere near as the monster describes to his creator that, ‘dreary glaciers are my refuge’. Arguably, Mary Shelley might have been inspired, as she wrote ‘Frankenstein’, while staying in Italy in a remote place in the mountains. Shelley also shows the isolation that Victor forced onto himself, rejecting company. This means there is no one there to make him do the right thing so he continues to make horrific mistakes. The monster and Victor are isolated together at the end and only have each other. When Victor dies, his creation kills himself as the last person who could accept him and give him reason for his existence has died, and he no longer wishes to be lonely. The reason for this loneliness is simply because of the way that he looks, that people are ‘prejudiced against’ him and only ‘behold a detestable monster’. Mary Shelley uses this to make the audience feel sorry for him and to show the reader that he has emotions just like a human. Much of this book criticises man for judging on appearance and shows that appearance and reality can be very different. The creature is ugly and deformed making him seem frightening to people where as all that he really wants is a friend and someone to love him like he describes to the blind man he has ‘no relation or friend upon earth’. On the complete opposite to this Victor Frankenstein is seen as a rational scientist but turns out to be an irrational obsessive. Mary Shelley is trying to get the point across that things are not always as they seem. Another important theme is that of the horror of child birth. In chapter five when Frankenstein gives birth to the creature, he immediately rejects it and is in a sense rejecting his â€Å"baby†. The monster in a sense has lost his â€Å"mother† at child birth and so is lonely. This was a very personal subject that Shelley decided to include within the book as she must have felt similar feeling to the creature after losing her own mother at child birth. She is showing through the creature how lonely it feels not to be loved by a creator or mother. Through the chapters when the monster is recounting his story to his creator he is trying to get Victor to take his responsibilities of creator and love his creation calling Victor his ‘natural lord and king’ The monster also shows the similarities between Victor and God being the creators and himself and Adam the first creations trying to explain this to Frankenstein saying to him, ‘I ought to be thy Adam’ At this point Victor believes in the total opposite, and wants nothing to do with his creation that he now regrets, trying to rid the monster telling him ‘there can be no community between you and me’ ‘we are enemies’ it is only later on when he starts to listen and feel for his creation that he ‘felt what the duties of a creator towards his creature were’ and that he ‘ought to render him’. I think that to many people Frankenstein is one of the most well known horror stories including all of the ingredie nts to frighten the audience. To me, I believe that Frankenstein is much less a horror story as it is a novel that questions our society and the people living in it. The old man tells the monster ‘the hearts of men, when unprejudiced by any obvious self-interest, are full of brotherly love and charity’. Throughout this book this quote is proved untrue. That people are always kind and giving when it does not interfere with their own interests, is shown as wrong. This book criticizes society and man, how prejudiced we are and the greed for fame. Although this book was written nearly 200 years ago the same messages still apply to today’s modern society.

Introduction. Food Security Is A Fundamental And Growing

Introduction Food security is a fundamental and growing problem in Timor-Leste, a nation that has is still rebuilding from their violent struggle for independence. The country’s turbulent and conflict-filled history, as well as a broad range of political and social issues, have greatly influenced the state of the nation today. Timor-Leste has a well-established dependency on agricultural production that, when it fails, sustains some of the highest levels of food insecurity and poverty in the world. However, the agriculture sector also provides Timor-Leste’s most promising opportunity to develop, reinvent, and implement systems that address underlying threats to food security and economic growth. This essay aims to provide some background†¦show more content†¦These weather events highlight one of the greatest threats to food security in Timor-Leste: climate change. With more than 80% of the Timorese population working as subsistence farmers (Williams et al., 2013), many fami lies are at-risk as a result of their reliance on agricultural outputs. Predictions are that by 2050, Timor-Leste’s climate will become approximately 1.5 °C hotter and 10% wetter and that the population is set to triple (Molyneux et al., 2012). This unprecedented increase in population size will place an even greater burden on an already strained food system. The sudden shift in weather patterns will also have an unpredictable impact on climate sensitive and socially essential resources such as soil and water (Barnett et al., 2007), as well as shocking coastal communities that are reliant on aquatic ecosystems (Valmonte-Santos et al., 2016). Since independence, Timor-Leste’s traditional agricultural systems have undergone few significant changes (Molyneux et al., 2012) and evidence has shown that Timor-Leste’s adoption rates of new agricultural technology are relatively low, despite the massive potential for yield improvements that could help to alleviate food insecurity (Jensen et al., 2014). Contemporary cropping technologies and chemical fertilizers cannot be easily accessed or afforded by the majority of subsistence farmers and as such they are rarely utilised.Show MoreRelatedThe Policy Process I : Background Briefing Essay1680 Words   |  7 Pageschallenging sustainable development issue of the twenty first century.
