Essay about Energy and the Environment Fossil Fuels

Energy and the Environment: Fossil Fuels Fossil Fuels are one of the most important things on this planet to the human race. Without fossil fuels we wouldnt have todays current means of transportation, we would have less heating for the general population, energy uses would be more expensive, and overall the economy and the world would not be able to sustain themselves. Even still, the fact that fossil fuels are on this planet will never change, but how we use them and what impacts their use has will always be an issue. Even though fossil fuels provide for the most percentage of energy usage in the world, there is still the issue of pollution and other environmental impacts. Just oil and natural gas alone provide for more than 60†¦show more content†¦Global warming is mainly caused due to carbon dioxide trapping the suns radiation and keeping it within the Earths atmosphere. The fact that burning fossil fuels releases carbon dioxide is why their use has such an impact on global warming. Over the last 150 years, burning fossil fuels has resulted in more than a 25 percent increase in the amount of carbon dioxide in our atmosphere (union of concerned scientists). This statistic gives enough support to the fact that fossil fuels and their use are fueling the global warming situation. Another issue related to the use of fossil fuels is acid rain. Acid rain is caused by sulfur dioxides in the air and has been increasing due to the burning of fossil fuels, especially coal, which ultimately pollutes the waterways. The main fact is that burning coal produces sulfur dioxide, an acidic gas that contributes to the formation of acid rain (Darvill). Coal is used to produce about 30 percent of the energy in the US. With this very large number, it can be seen that the amount of acid rain will be greatly reduced if we can burn less amounts or use cleaner burning methods in order to protect the environment. After learning a great deal about fossil fuels one can see that they are obviously NEEDED by the human population and that their use is inevitable. On the other hand, fossil fuels may lead to substantial, and irreversible,Show MoreRelatedThe Effects Of Fossil Fuel Energy On The Environment And The Pocket987 Words   |  4 PagesIn the last decades energy consumption has come to a time where people started noticing the climate changes and the effect of fossil fuel energy for not only being environmentally destructive, but also causing Global warming (the warming that occurs as a result of increase emissions of greenhouse gases) has become a very big issue worldwide.

Difference Of A Child s Comprehension - 860 Words

Description of the Study The purpose of this study was to examine the difference of a child’s comprehension when being read with a traditional book versus being read to with an electronic book. The independent variable is reading and the dependent variable is the comprehension and learning the child receives from the parent-joint reading. Also, the dependent variable is the background the children come from and the families learning history. In the study, by Marina Krcmar and Drew P. Cingel, there were multiple hypothesis and multiple research questions, but the main one I will be focusing on is hypothesis one. Krcmar and Cingel stated that the children will exhibit higher comprehension when their parents read to them using a traditional book compared to using an electronic book. Seventy parent-child dyads were recruited from child care centers. The children’s ages ranged between 24 and 60 months while the study did not report the age of the parents it did say nearly all of the parents were females. The data was collected with consent forms that the parents filled out before participating and took a brief questionnaire about the child’s reading experience. If the parents were not familiar with the iPad technology, they were trained by someone who was part of the research team. When parents were comfortable, the process of the study began. In the study, the independent variable (reading) was measured in a period of ten minutes. For the ten minutes, the parents would read toShow MoreRelatedTypes Of Learning Disorders And Their Signs Essay1657 Words   |  7 PagesLearning Disorders and Their Signs Could it be that your child struggles with school?

Wildlife Biodiversity and Net Deforestation Rates Free Essays

Around the world, forests are being logged for timber and paper pulp and cleared to grow mono-crops like soy and palm oil while they are deteriorating from the impacts of global warming. Deforestation is a major driver of global warming, responsible for up to 20 per cent of global greenhouse gas emissions–more than all the cars, trucks, planes, boats and trains in the world combined. Deforestation doesn’t just threaten our climate, it threatens the livelihoods of 1. We will write a custom essay sample on Wildlife: Biodiversity and Net Deforestation Rates or any similar topic only for you Order Now 6 Billion people that rely on forests for food and economic activity. Forests also serve as habitats to rare and undiscovered animal and plant species and play a key role in providing water and preventing flooding and erosion. Ending deforestation and protecting forests will not only preserve biodiversity and defend the rights of forest communities, it is also one of the quickest and cost effective ways of curbing global warming. Greenpeace is campaigning for zero deforestation, globally, by 2020. Deforestation,  clearance  or  clearing  is the removal of a forest or stand of trees where the land is thereafter converted to a non-forest use. 1]  Examples of deforestation include conversion of forestland to farms, ranches, or urban use. About half of the world’s original forests had been destroyed by 2011, the majority during the previous 50 years. [citation needed]  Since 1990 half of the world’s  rain forests  have been destroyed. [citation needed]  More than half of the animal and plant species in the world live in trop ical forests. [2] The term  deforestation  is often misused to describe any activity where all trees in an area are removed. not in citation given][neutrality  is  disputed]  However in  temperate climates, the  removal of all trees in an area[not in citation given]—in conformance with  sustainable forestry  practices—is correctly described as  regeneration harvest. [3]  In  temperate mesic climates, natural regeneration of forest stands often will not occur in the absence of disturbance, whether natural or anthropogenic. [4]  Furthermore, biodiversity after regeneration harvest often mimics that found after natural disturbance, including biodiversity loss after naturally occurring rainforest destruction. 5][6] Deforestation occurs for many reasons: trees are cut down to be used or sold as fuel (sometimes in the form of  charcoal) or timber, while cleared land is used as  pasture  for livestock, plantations of commodities and settlements . The removal of trees without sufficient  reforestation  has resulted in damage to  habitat,  biodiversity  loss and  aridity. It has adverse impacts on  biosequestration  of atmospheric  carbon dioxide. Deforestation has also been used in  war  to deprive an enemy of cover for its forces and also vital resources. A modern example of this was the use of  Agent Orangeby the United States military in Vietnam during the  Vietnam War. Deforested regions typically incur significant adverse  soil erosion  and frequently degrade into  wasteland. Disregard or ignorance of intrinsic value, lack of ascribed value, lax forest management and deficient environmental laws are some of the factors that allow deforestation to occur on a large scale. In many countries, deforestation, both naturally occurring and human induced, is an ongoing issue. Deforestation causes  extinction, changes to climatic conditions,  desertification, and displacement of populations as observed by current conditions and in the past through the fossil record. [5] Among countries with a per capita  GDP  of at least US$4,600, net deforestation rates have ceased to increase. [when? ][7][8] ————————————————- Causes According to the United Nations Framework Convention on Climate Change (UNFCCC) secretariat, the overwhelming direct cause of deforestation is agriculture. Subsistence farming  is responsible for 48% of deforestation;  commercial agriculture  is responsible for 32% of deforestation;  logging  is responsible for 14% of deforestation and fuel wood removals make up 5% of deforestation. [9] Experts do not agree on whether industrial logging is an important contributor to global deforestation. [10][11]  Some argue that poor people are more likely to clear forest because they have no alternatives, others that the poor lack the ability to pay for the materials and labour needed to clear forest. 10]  One study found that population increases due to high fertility rates were a primary driver of tropical deforestation in only 8% of cases. [12] Other causes of contemporary deforestation may include  corruption  of government institutions,[13][14]  the  inequitable  distribution of wealth and power,[15]  population growth[16]  andoverpopulation,[17][18]  and  urbanization. [19]  Globalization  is often viewed as another root cause of deforestation,[20][21]  though there are cases in which the impacts of globalization (new ? ws of labor, capital, commodities, and ideas) have promoted localized forest recovery. [22] The last batch of sawnwood from thepeat forest  in Indragiri Hulu, Sumatra,Indonesia. Deforestation for  oil palmplantation. In 2000 the United Nations  Food and Agriculture Organization  (FAO) found that â€Å"the role of population dynamics in a local setting may vary from decisive to negligible,† and that deforestation can result from â€Å"a combination of population pressure and stagnating economic, social and technological conditions. [16] The degradation of forest ecosystems has also been traced to economic incentives that make forest conversion appear more profitable than forest conservation. [23]  Many important forest functions have no markets, and hence, no economic value that is readily apparent to the forests’ owners or the communities that rely on forests for their well-being. [23]  From the perspective of the developing world, the benefits of forest as carbon sinks or biodiversity reserves go primarily to richer developed nations and there is insufficient compensation for these services. Developing countries feel that some countries in the developed world, such as the United States of America, cut down their forests centuries ago and benefited greatly from this deforestation, and that it is hypocritical to deny developing countries the same opportunities: that the poor shouldn’t have to bear the cost of preservation when the rich created the problem. [24] Some commentators have noted a shift in the drivers of deforestation over the past 30 years. 25]  Whereas deforestation was primarily driven by subsistence activities and government-sponsored development projects like  transmigration  in countries like  Indonesia  and  colonization  in  Latin America,India,  Java, and so on, during late 19th century and the earlier half of the 20th century. By the 1990s the majority of deforestation was caused by industrial factors, including extractive industries, large-scale cattle ranching, and extensive agriculture. [26] [edit] Wildlife conservation  i s the practice of protecting  endangered plant and animal species  and their  habitats. Among the goals of wildlife conservation are to ensure that nature will be around for future generations to enjoy and to recognize the importance of  wildlife  and  wilderness  lands to humans. [1]Many nations are  government agencies  dedicated to wildlife conservation, which help to implement policies designed to protect wildlife. Numerous independent  nonprofit organizations  also promote various wildlife conservation causes. [2] Wildlife conservation has become an increasingly important practice due to the negative effects of  human activity  on  wildlife. The science of extinction. An endangered species is defined as a population of a living being that is at the danger of becoming extinct because of several reasons. Either they are few in number or are threatened by the varying environmental or predation parameters. ————————————————- Government involvement The Wildlife Conservation Act was enacted by the Government of India in 1972. Soon after the trend of policy makers enacting regulations on conservation a strategy was developed to allow actors, both government and non-government, to follow a detailed â€Å"framework† to successful conservation. The World Conservation Strategy was developed in 1980 by the â€Å"International Union for Conservation of Nature and Natural Resources â€Å"(IUCN) with advice, cooperation and financial assistance of the United Nations Environment Programme (UNEP) and the World Wildlife Fund and in collaboration with the Food and Agriculture Organization of the United Nations (FAO) and the United Nations Educational, Scientific and Cultural Organization (Unesco)†[9]  The strategy aims to â€Å"provide an intellectual framework and practical guidance for conservation actions. [9]  This thorough guidebook covers everything from the intended â€Å"users† of the strategy to its very priorities and even a map section containing areas that have large seafood consumption therefore endangering the area to over fishing. The main sections are as follows: * The objectives of conservation and requirements for their achievement: 1. Maintenance of essential ecological processes and life-suppo rt systems. 2. Preservation of genetic diversity. 3. Sustainable utilization of species and ecosystems. * Priorities for national action: 1. A framework for national and subnational conservation strategies. . Policy making and the integration of conservation and development. 3. Environmental planning and rational use allocation. * Priorities for international action: 1. International action: law and assistance. 2. Tropical forests and drylands. 3. A global programme for the protection of genetic resource areas. Map sections: 1. Tropical forests 2. Deserts and areas subject to desertification. Importance Of Wildlife 37  Ã‚  6  StumbleUpon4 If you were of the opinion that cultivated plants and domesticated animals is what wildlife consists of, you are mistaken. Wildlife, in fact, comprises of the innumerous varieties of wild plants, animals, fungi and microorganisms that exist on our planet earth, rather than just cultivated plants and domesticated animals. Knowingly or unknowingly, we largely depend on this wildlife for every elementary requirement in our life. The food we eat, the clothes we wear, the medicines we consume, a variety of building materials used for construction, numerous chemicals used for manufacturing our necessities, all are extracted from the wildlife existing around us. A study by the American Association for the Advancement of Science indicates that as many as 40,000 species of plants, animals, fungi and microscopic animals benefit us in some way or the other. To know the various benefits that this wildlife provides us, read on further. Benefits Of Wildlife Benefits To People Wildlife and nature have largely been associated with humans for numerous emotional and social reasons. A simple stroll around the park amidst some birds provides a fresh breath of life and charges our batteries. Apart from bird feeder in the backyard, we can also take up other active pastimes, such as hiking, hunting, canoeing or wildlife photographing to relieve our parched nerves. Since prehistoric times, animals have been highly useful to us in providing food, clothing and source of income. Benefits To Natural Processes Wildlife plays an essential role in the ecological and biological processes that are yet again significant to life. The normal functioning of the biosphere depends on endless interactions amongst animals, plants, and microorganisms. This, in turn, maintains and enhances human life further. To add on, these ecological processes are vital for agriculture, forestry, fisheries and other endeavors that support human life. Besides, there are several biological processes wherein wildlife plays a key role, such as pollinization, germination, seed dispersal, soil generation, nutrient cycling, predation, habitat maintenance, waste breakdown, and pest control. Benefits to Science, Agriculture, Medicine Studies indicate that woodpeckers are capable of destroying 90% of codling moth larvae residing under the bark of trees. This shows the significance of wildlife and wildlife habitat for preserving genetic diversity. Hence, places where agriculture, forests, and fisheries depend on crops or stocks can ensure that such living resources are enough to withstand the ever-increasing list of threats. Further, in medicine, development of new drugs and treatments are largely dependent on wildlife and wildlife habitat. Interestingly, most pharmaceutical products are a result of discovering or developing wildlife species and not discoveries through the traditional chemistry principles. Today, most medicinal remedies contain at least one ingredient derived from a wild plant or animal. How to cite Wildlife: Biodiversity and Net Deforestation Rates, Papers

Advance Pathophysiology for Health Professionals-myassignmenthelp

Question: Discuss about theAdvance Pathophysiology for Health Professionals for Burns. Answer: Thermal injury to the cell, mostly burns injuries have been widely reported in patients that require immediate rehabilitation through systematic interventions. Thermal injuries are common in patients when they come in contact with boiling water, fire and objects with the high thermal capacity to cause burns. The underlying pathophysiology of thermal burns is to be understood for clinical professionals for providing accurate care measures. In case of the first degree and second-degree burns, the cells appear to be red and develop blisters. In addition, there is swelling of the tissues. In case of third-degree burns, the cells are blackened or white in color in addition to a charred condition which appears numb (Stanojcic et al. 2018). The present understanding of the pathophysiology of burn cell injury focuses on three zones of injury; zone of coagulation, the zone of stasis, and zone of hyperemia. The zone of coagulation is the area suffering the most damage due to the injury. This has the zone of stasis surrounding it, indicating low levels of perfusion and increased inflammation. The zone of hyperemia has minimal microvascular perfusion with increased necrosis. Thermal injury to the cells is responsible for inducing an immunosuppressed state predisposing patients to complexities (CopsteadBanasik, 2013). The mechanism of cellular dysfunctioning has been linked with thrombosis of vessels because of vascular damage, up-regulation of inflammatory mediators and proapoptotic factors. The inflammatory action leads to rapid formation of oedema as a result of vasodilation, increased osmotic activity and increased extravascular osmotic activity. Further changes in interstitial tissue hold much importance (Nielson et al., 2017). References Copstead, L. C., Banasik, J. L (2013).Pathophysiology (5th ed.). St Louis, Missouri: Saunders Elsevier.
