In this day and age where energy is one of the greatest factors in world events, it is unsurprising to see nuclear energy, the bridge between fossil fuels and renewable resources, argued for and against so fiercely. Yet under this umbrella term of “nuclear energy” that people enjoy throwing around, there are two wildly different forms of energy. Things that perhaps shouldn’t be lumped together so haphazardly. Those are Nuclear Fission and Nuclear Fusion.
The general attitude by the public towards nuclear reactors is that of fear or disapproval simply due to its name or the rumors. Nuclear reactors are merely devices that sustain chain reactions, in which only one of the emitted neutrons hits another nucleus to create fission. Though nuclear reactors cannot become a weapon or a bomb, some of the dangers relate to our lives to the extent that we may need to seek alternatives, as demonstrated by the reactors in Three Mile Island and Chernobyl.
In this essay I hope to talk to you about nuclear fusion. I will do this by outlining a few important aspects to take into consideration when talking about nuclear fusion. I hope to tell you what nuclear fusion is and when it was discovered. I hope to talk about the dangers involved with nuclear fusion and will it be controlled. I want to talk a bit about some previous nuclear disasters that humanity has faced in the past. I hope to talk a little bit about nuclear waste. I also hope to talk about some applications of nuclear energy in the 21st century. I hope to talk about some future uses of nuclear fusion that I have thought of. Finally I hope to give a conclusion about nuclear fusion and talk about what I have learned.
When one hears the word Eugenics, one associates it with the terrible actions of Nazi Germany, but Germany was not the only country, which adopted the horrible social movement known as Eugenics. It took place in countries such as Great Britain, Sweden, Australia, USA and many more, all of whom introduced policies and programs such as birth control, marriage restrictions, segregation, forced abortions and sterilization, and worst of all genocide with aims to improve the human race by potentially breeding out undesired traits and ridding society of all those deemed as “unfit”. The idea of breeding out undesirable genes or traits is loaded with problematic value judgments, and the various ways that such ideas have been implemented as policy have scared many people and lead to the deaths of millions of people, therefore it undoubtedly has a bad reputation.
Nuclear energy results from mass-to-energy conversions that occur in the separation of atoms larger than Iron or combining atoms smaller than Iron. The slight amount of mass that is lost from either the separation or combination follows the Einstein’s mass energy relation E=mc2 where m is defined as the mass and c is the speed of light.
The global energy demand is increasing as years go by as there is a rapid growth of population in deed of power. Due to the high demand for energy, many people are opting to replace other forms of energy with nuclear power because of its safety, reliability, and sustainability. In addition, it is one of the cleanest carbon free sources of energy available in the world today. Nuclear power is the use of continuous nuclear fission to produce electricity and heat. However, there are a number of controversies over the use of nuclear energy with some supporting its use while others opposing the use of nuclear energy. Despite the controversy on whether to use nuclear energy as an alternative, nuclear power has proved to be safe, reliable, clean, and inexpensive. Therefore, Nuclear energy should replace other forms of power around the globe because it is more environmentally friendly, cost effective, and safe for use and to exist with human beings compared to other forms of energy being used today.
Are Puppy Mills Bad? A young girl got a puppy for Christmas; weeks later her puppy died. It was ruled that this puppy died from a severe respiratory disease which caused the air passages to become closed resulting in slow suffocation. It was later discovered that this puppy had been raised in a puppy mill. A puppy mill is an inhumane organization that breeds and sells puppies. Puppy mills have been around since before 1970. To this day there are more than 10,000 mills existing in the United States (Humanesociety). These mills are mostly inspected and licensed by the U.S.D.A. (National Puppy Mill Project). It has been estimated that a mill in Iowa brought in $15 million a year (Hesse). There are people who were in need of money who began
Prior to the introduction of nuclear energy, fossil fuel was thought to be the only available source in producing energy. Although fossil fuel, such as coal, petroleum, and natural gas, contains high energy value, it produces too many harmful byproducts that ultimately pollute our environment. With the rising concerns over global warming as more and more greenhouse gases accumulate in our Earth’s atmosphere, many voice such opinions that new alternative, yet sustainable method must be adopted to produce energy. Nuclear energy is one of the several alternative energy sources that have been introduced ever since. Nuclear energy’s various advantages entice many countries to start practicing it. One must consider the amount of energy generated by nuclear fuels, as they are highly-concentrated energy sources. Small uranium pellets, which are the most common form of fuel in generating nuclear energy, can generate as much electricity as a trainload full of coal does. In addition, nuclear power plants do not produce green house gases as byproducts.
In the article, “Welfare concerns associated with pedigree dog breeding in the UK” by Nicola J. Rooney and David R. Sargan, the topic of the welfare for pedigree dogs is discussed. Pedigree dog breeding can be summed up as breeding for certain physical traits the Kennel Clubs look for, specifically in the different breeds of dogs. Rooney (2010) states that, “In the UK, numerous pedigree dogs of many breeds experience compromised welfare due to the direct and indirect effects of selective breeding” (p. 133). People are breeding these dogs for looks and in turn the dog’s health is being compromised. Just like in the article by King, people are selective breeding for physical characteristics and Rooney touches upon the consequences of selective breeding for such characteristics. An in text citation states, “The indirect effects of selective breeding for appearance include very significantly reduced genetic diversity unevenly spread across the genome” (Jones et al 2008, p. 134). Dogs that are selected for looks with their genetics ignored are more likely to develop health issues, such as collie eye anomaly, cardiac problems, and diabetes to name a few. In both articles, King and Rooney discuss the trend of how dogs used to be bred for their working purpose and over time their companionship with humans
One of these fuels is known as the element thorium. Thorium has great potential to be a reactor fuel because it outputs far more energy at the same cost, as well as being a safer material to use in the event of a nuclear meltdown (“Pros and Cons”). Another pro of nuclear energy is its relative safety compared to other sources of energy. Fossil fuel energy comes with a high rate of accidents and death. Mining accidents, oil rig explosions, and illnesses such as lung cancer and other ailments are far more common to occur than issues with nuclear reactors. Nuclear power plants can also be easily controlled and regulated with the right tools, and many safety precautions are taken to prevent
Eugenics is the science of using artificial selection to improve genetic features of the population. It is thought that improvement of the human race can be seen through sterilization of people who exhibit undesirable traits and selective breeding. Often called Social Darwinism, the concept was widely accepted during the time of World War I. It quickly became a taboo after World War II when Nazi Germany used it as an excuse for genocide. The thought of improving the human race by manipulating who is allowed to breed can either be appalling or compelling. There are a few appealing aspects to the act of eugenics. If eugenics were applied, the world could potentially see a decrease in disease, a rise in intelligence, and heightened physical aesthetic in humans. But, ethically it crosses many boundaries that have prevented this idea from going into world-wide effect in the past.
The United States currently possess several valuable capabilities within our intelligence to support our homeland security efforts, but we also face a number of limitations as well. Places like Fusion Centers for example, which are operational and resourceful centers within their appropriated state and major cities, are considered an invaluable resource in the fight against terrorism and other threats. These centers were created with the purpose of sharing intelligence and information among numerous agencies to reorganize operations, optimize our ability to fight crime and terrorism, and increase resources by the integration of data from different sources.
Genetic engineering is the modification of an organism’s genetic composition by artificial means, often involving the transfer of specific traits, or genes, from one organism into a plant or animal of an entirely different species. Human beings ought to consider the pros and cons of genetic engineering before using it. It is a contentious topic because people have different views of weather genetic engineering is safe or not. This essay will look more on the advantages and disadvantages of genetic engineering.
Firstly, nuclear power generation has low greenhouse gas emissions, which make it good for the environment. The actual fission
