Are Zoos Inhumane? Essays -- Animal Cruelty

In the film, Madagascar, zoos are depicted as a sanctuary in which all the exotic animals are kept safe and are open for the public to view. But many would argue that zoos are inhumane, the caging of animals for our personal entertainment is unjustifiable. Those who believe that zoos are wrong and should be destroyed are animal rights activist; they believe that animals should be allowed to choose their own destiny. Those that believe that zoos are an important part of our lives are scientist and zoologist. This debate has gone on for generations and average folk are stuck in the middle, not knowing which side to stand on. The animals being kept in captivity could not be interviewed; their side of the story will be based on interpretation on their movement and interaction with animals in the zoo and in the wild. Are animals better suited to live in the harsh conditions of the wild or are they better suited to live their lives safely in captivity? Many animal rights activist argue that animals should be allowed to live their lives in the wild instead of captivity. That we as humans have no right to neither alter the fate of other species nor use them for our personal benefits. PETA who is well known for their animal rights view argue that â€Å"Captive animals are deprived of everything that is natural and important to them and as a result, they become bored and lonely and many even suffer from a condition called zoochosis.† (PETA 1) Zoochosis is a condition in which the animal wonders back and forth usually in the same position for hours on end. This condition is only seen in the zoos as a result of the animal’s captivity. As a result zoos provide these animals with Prozac, which is a mood-altering drug to help prevent public atte... ... in todays society. But one thing is for sure many would argue that zoos have brought humans and animals closer together for the good and the bad. Works Cited "Zoos." Animal Cruelty -. N.p., n.d. Web. 12 May 2015.

Abstract for Literature review based on Dentists’ Knowledge of Ionising Radiation dental radiography.

Abstract for literature review Despite there is a rapid growth in the technology that has myriad benefits in improving the interventions of dental health, only a fewer dentists are well aware of the risk hazards of some these modern technologies (Praveen, et.al. 2013). Large body of evidence suggests the lack of knowledge in dentists in regards to the risks associated with ionising radiation while giving dental service (Rout and Brown, 2012). More importantly, only a handful of studies have attempted to unveil the facts and current state of knowledge and awareness associated with detrimental effects of ionising radiation in Australian and Jordanian dentists. This study, through questionnaires and interviews, examined the dentists that are giving services in Australia and Jordan and assessed their knowledge of such effects that are linked with ionising radiations. The study was carried through intense literature review was carried out to collect the current background in the subject area and the findings of these s tudies were critically reviewed. Focus of the literature review was based upon the different factors, such as the complications of ionising radiation, complications in different age group people, preventive measures and the current state of knowledge in the dentists all around the globe. Praveen, et.al (2013) suggests that radiation in dentistry is mainly used for diagnostic purposes and in a dental set-up usually the practicing dentist exposes, processes and interprets the radiograph. Although the exposure to such radiation is kept as very less, it is essential to reduce the exposure to the minimum to the dental personnel and patients in order avoid the carcinogenic and organ damaging effects that can be produced by it.. Several radiation protection measures have been advocated to ameliorate these effects. Dose dependent radiation exposure was identified as a one of the key measures in limiting the use of ionising radiation. As suggested by White and Mallya (2012), wise selection of patients to treat with ionising radiation and implement patient-specific reason, which ensures greater benefits than the harms are the two easiest ways to tackle with the risks associated with ionising radiation. However, Ayatollahi et.al (2012) suggests that this practice is not adequately implemented in majority of the dental clinics. Secondly, the review identified children as most susceptible to radiation exposure. Preventive measures such as use of special radiation protection equipments and dose dependent exposure were suggested to be central in minimising the effects of ionising radiation in children in dental clinics. Moreover, it was suggested that knowledge of such risks in dentists can make a significant contribution in the improvement of safe dental practice, ensuring adequate safeguards of both patients and dentists. The literature came up with a conclusion that up to date and evidenced based knowledge is still lacking in dentist regarding the risks of radiation hazard. This will need re-educating and re-training the dentists, make them aware of ionising radiation risks, and make them able to answer any queries from patients about the risks of ionising radiations (Praveen, et.al. 2013). As part of the clinical practice, all dentists are required to undertake radiography as part of the clinical practice in which dentists and members of the dental team, must understand the basic principles of radiation physics, hazards and protection, and should be able to undertake dental radiography safely with the production of high quality, diagnostic images (Rout and Brown, 2012). Although the grey area that was identified was that, dentists are poorly informed on how to use medical imaging tools safely and efficiently. Furthermore, they are found to underestimate the radiation risk and their devastating effec ts in patients’ long term health. In addition, some of the studies revealed that despite some knowledge on the harmful effects of ionising radiation in patients, as well as in their own health, the knowledge of patient’s protection including the exposure distance and prevention of radiation leakage, protection of personnel, i.e. the occupational risk hazards of ionising radiation, dentists were reluctant to employ these safety measures in day to day practice (Rout and Brown, 2012)). Considering the context of this study, no research has evaluated Australian and Jordanian dentists’ knowledge on the risks associated with ionising radiation in the dental clinics; suggesting the importance and need to carry out this study. This puts patients of different age groups in significant risk of developing pathological conditions that are induced by the exposure to ionising radiation. Thus, designing a training module to teach dentists about radiation safety and risk is mandatory for safe dental health practice. This study provides insights into developing new strategies, policies and practices to minimise or even avoid such risks in the future.

My Personal Attitude To Nuclear Energy - Free Essay Example

Sample details Pages: 3 Words: 1023 Downloads: 9 Date added: 2019/08/08 Category Energy Industry Essay Level High school Tags: Nuclear Energy Essay Did you like this example? I dont know why nuclear energy has a bad rap, mainly it is because there are misconceptions about the safety of it and when people are uneducated they tend to fight against what is actually very beneficial. Nuclear energy is energy that is released either by splitting atomic nuclei or by forcing the nuclei of atoms together. Nuclear energy comes from mass-to-energy transitions that occur during atom splitting. This explains the well-known mathematical formula of Albert Einstein E = mc2. The equation says: E [energy] is equal to m [mass] times c2 [c denotes the speed of light]. This means that the mass is multiplied by the square of the speed of light. Don’t waste time! Our writers will create an original "My Personal Attitude To Nuclear Energy" essay for you Create order Nuclear energy is produced by a controlled nuclear chain reaction and creates heat†which is used to boil water, produce steam, and drive a steam turbine. power plants actually produce less green-house gasses than other energy sources.   Nuclear energy has led us, and the United States   to have become a major superpower in the world. The average global efficiency of nuclear power is 92%. Throughout the history of nuclear power, there were only three major natural disasters Three Mile Island, Chernobyl and Fukushima. Over the past 25 years there have been more than 10 large disasters with fossil fuel energy the largest of them reset the BP oil. Nuclear power can come from the fission of uranium, plutonium or thorium or the fusion of hydrogen into helium. Today it is almost all uranium. The basic energy fact is that the fission of an atom of uranium produces 10 million times the energy produced by the combustion of an atom of carbon from coal. So, the real question is why arent we using it more? Its because there are misconceptions about the safety of it and when people are uneducated they tend to fight against what is actually very beneficial. Nuclear energy is energy that is released either by splitting atomic nuclei or by forcing the nuclei of atoms together. Nuclear energy is produced by a controlled nuclear chain reaction and creates heat†which is used to boil water, produce steam, and drive a steam turbine. Nuclear power can come from the fission of uranium, plutonium or thorium or the fusion of hydrogen into helium. Today it is almost all uranium. The basic energy fact is that the fission of an atom of uranium produces 10 million times the energy produced by the combustion of an atom of carbon from coal. Nuclear power plants need less fuel than ones which burn fossil fuels. One ton of uranium produces more energy than is produced by several million tons of coal or several million barrels   So all that we have to decide is what do we want more energy efficiency with minimal risks   or use of   other energy sources that are less efficient like coal or solar.Nuclear power plants can generate up to a million times more energy than coal, of oil. In France, nuclear power is the most widespread, supplying 80 percent of the countrys electricity.   By this we can see that nuclear power is beneficial. A protest movement exists, called Sortir du Nucleaire, or Get Out of Nuclear, but it appears to have made little headway. Nuclear energy was first discovered accidentally by French physicist Henri Becquerel in 1896, when he found that photographic plates stored in the dark near uranium were blackened like X-ray plates, which had been just recently discovered at the time. As of 2004, nuclear power provided 6.5% of the worlds energy and 15.7% of the worlds electricity, with the U.S., France, and Japan together accounting for 57% of nuclear generated electricity. Nuclear energy (nuclear power) accounts for about 19 percent of the total electricity generated in the United States, an amount comparable to all the electricity used in California, Texas and New York, three most populous states. There are 104 commercial nuclear generating units that are fully licensed by the U.S. Nuclear Regulatory Commission (NRC) to operate in the United States. Of these 104 reactors, 69 are categorized a pressurized water reactors (PWRs) totaling 65,100 net megawatts (electric) and 35 units are boiling water reactors (BWR) totaling 32,300 net megawatts (electric). On June 27, 1954, the USSRs Obninsk Nuclear Power Plant became the worlds first nuclear power plant to generate electricity for a power grid, and produced around 5 megawatts electric power. Russia has begun building floating nuclear power plants. The 100 million ($204.9 million, 2 billion  ±) vessel, the Lomonosov, to be completed in 2010, is the first of seven plants that Moscow says will bring vital energy resources to remote Russian regions. The International Nuclear Event Scale (INES), developed by the International Atomic Energy Agency (IAEA), is used to communicate the severity of nuclear accidents on a scale of 0 to 7. The Chernobyl disaster in 1986 at the Chernobyl Nuclear Power Plant in the Ukrainian Soviet Socialist Republic (now Ukraine) was the worst nuclear accident in history and is the only event to receive an INES score of 7. Nuclear energy is released by three exothermic processes:   Radioactive decay, where a proton or neutron in the radioactive nucleus decays spontaneously by emitting a particle Fusion, two atomic nuclei fuse together to form a heavier nucleus Fission, the breaking of heavy nucleus into two nuclei. The sun uses nuclear fusion of hydrogen atoms into helium atoms. This gives off heat and light and other radiation. Nuclear energy is really making a comeback because nuclear energy has virtually none greenhouse gases emission and therefore isnt warming the planet and causing global warming like some other energy sources. Although, i do see the point of the other side when they say that it is hard to dispose of the waste is a problem because you have to deal with the problem of the waste, but with proper regulation of it the benefits out way any negative effects. Nuclear   energy has lead us, the usa   to become the top super power in the world. The global average efficiency of nuclear energy is 92%.In the entire history of nuclear energy production, there have only been 3 major disastersThree Mile Island, Fukushima, and Chernobyl. In the past 25 years, there have been over 10 major disasters with fossil fuel energythe largest of which was the BP oil spill.
