The Era Of Political Structure - 1181 Words

Each era of political structure brings, in its own way, something that our nation needed at that specific point in time. With each need answered comes a needed question, for that which works for one era make have disastrous consequences for the next. Whereas the founding era, or the eighteenth century to the american revolution, questioned the constitution, the time after questioned the union and Lincoln’s words. The questions asked during each era were crucial to the development of our nation and government. Without this chain of events and the specific form of thinking for each era, we would not be where we are today. Perhaps the most important era is the one that continues to this day. For though all of the eras are extremely vital to†¦show more content†¦But in general his new wave of thinking, guided by his extensive education and and influence by German philosophy, paved the way for new ideals. This is turn helped to shape the Progressive Era, whether that is ow ed more to his lengthy education culminating in a Phd and multiple published books or the more European way of thinking that Wilson adapted. The progressives are openly critical of the Declaration of Independence and as a majority, they disagreed and even distrusted the foundation of the American founding. As Wilson was quoted saying in 1911, â€Å"If you want to understand the Declaration of Independence, do not repeat the Preface†. By taking out the preface of the Declaration of Independence, the only part left is the initial complaints agains the Monarch of England. The whole section dictating how to form a government is no longer available. Progressives like Wilson, felt that the only thing the Founders were qualified to put down in writing that would resist the test of time, was their displeasure with England, not how to run a new country. At the time of the writing of the Declaration, the main problem was getting rid of tyranny. Specifically, within the Declaration of Independence, Jefferson explicitly states that the document is â€Å"universal, absolute truth†, meaning that every law set to govern the nation will hold true forever. Even Lincoln believed this was the brilliant move on

Essay on Cause and Effects of Smallpox - 1520 Words

Cause and Effects of Smallpox Smallpox is caused by the variola virus that emerged in human populations thousands of years ago. Smallpox is a specific, infectious, and highly contagious febrile disease known only to be transmitted by humans. It is caused by a virus from air currents which are eventually passed on from person to person. Smallpox varies from a mild form without skin manifestations to a highly fatal hemorrhagic form. Edward Jenner, an English physician, discovered a means of preventing smallpox through vaccination. Gradually mass vaccination programs were introduced in many parts of the world. Smallpox was the first disease conquered by human beings and was eradicated by vaccination. The last known cases of naturally†¦show more content†¦Humans are the natural hosts of smallpox and it is not known to be transmitted by insects or animals. (WHO, 2005) Cause and Effects of Smallpox†¦2 Exposure to the virus is followed by an incubation period which people may not feel any sign of symptoms. The incubation period can range between 7 to 17 days. People are not contagious during this time period. After the incubation period, high fever, chills, severe headache and backache, and general malaise begin to develop. Your body temperature can reach up to 106 degrees Fahrenheit. After 2 to 4 days, a rash emerges first as small red spots on the tongue and in the mouth. The spots develop into sores which spread large amounts of the virus into the mouth and throat. The person becomes most contagious during this phase. Soon after, the smallpox rash appears on exposed portions of the body: the face, forearms, wrists, palms, lower legs, feet, and soles. Usually the rash spreads to all parts of the body within 24 hours. As the rash appears, the fever usually falls and the person may start to feel better. The rash becomes raised bumps on the third day of the rash. The bumps fill with a thick, opaque fluid and often have a depression in the center that looks like a bellybutton. (CDC, 2004). This is a major distinguishing characteristic of smallpox that occurs on the fourth day. Until scabs form over the bumps, fever often will riseShow MoreRelatedThe Eradication of Smallpox Smallpox is a disease that has a very high infection rate within the1300 Words   |  6 Pages The Eradication of Smallpox Smallpox is a disease that has a very high infection rate within the human population.

Changes in Blood Pressure Classification

Question: Discuss about the Changes in Blood Pressure Classification. Answer: Introduction: Hypertension is the most prevalent disease in Australia. Hypertension mainly occurs due to irregular food habit and unhealthy lifestyle. Hypertension can be classified into different categories based on the level of blood pressure. There are varied complications and different treatment options are associated with each category of hypertension. In this essay case of Amanda and Jim is discussed. Amanda and Jim belong to different grades of hypertension. Hence, different goals should be set and different treatment should be given to Amanda and Jim. Educational plan for control of hypertension in case of Amanda and Jim is also discussed. This educational plan should comprise of education for food, physical exercise, smoking and alcohol consumption, psychological and social issues, blood pressure monitoring and medication. Prevalence of hypertension: High blood pressure ( 140/90 mmHg) is the most frequently treated disease in Australia. In Australia, approximately 9 out of 100 patients are hypertensive patients treated at general practitioner. Majority of these patients are with chromic hypertension and only 4.5 % patients are newly diagnosed patients. Prevalence of hypertension is slightly higher in men (34 %) as compared to the women (29 %). 50 % patients of hypertension are generally associated with other heart and cardiovascular complications and approximately 11 % are associated with diabetes. In Australia, it is observed that high blood pressure increases with the age of the person (ABS, 2013). Primary hypertension can be mainly caused due to the smoking, being overweight or obese, alcohol consumption, lack of exercise, unhealthy diet comprising of high salt and saturated fat and family history of high blood pressure. Secondary hypertension can be mainly caused due to kidney disease, endocrine disease and narrowing of aorta. Secondary hypertension can also be caused due to steroidal drugs, contraceptive pill and pregnancy (Harrison et al., 2017). Grading system for hypertension: Blood pressure can be graded in three categories like grade 1 (SBP 140-159 or DBP 90-99), grade 2 (SBP 160-179 7or DBP 100-109) and grade 3 (SBP 180 or DBP 110). Grade 1 hypertension mainly occurs due to circulatory, vascular or renal response to environmental and genetic stimuli. In grade 1 hypertension, there are structural and functional alterations in heart and arteries of the patient. There can be occurrence of more than one risk factors in grade 1 hypertension patients. There would not be target organ damage in patients with grade 1 hypertension. Amanda may be suffering through grade 1 hypertension. Grade 1 hypertension patients should be assessed to identify early stage cardiovascular marker in the patient and identify specific treatment to attenuate these markers (Trana and Giangb, 2014; Kim et al., 2017). Patients of grade 1 hypertension should be traded with antihypertensive drugs like angiotensin converting enzyme inhibitors (ACE inhibitors) or angiotensin II receptor an tagonists. For Amanda also same drug was prescribed. Grade 2 hypertension is considered as the progressive disease. Grade 2 hypertension can occur due to inability of heart and cardiovascular system to control blood pressure. This may occur due to the persistent structural and functional changes in the heart and arteries. Grade 2 hypertension can be associated with the more than two risk factors. If grade 2 hypertension doesnt controlled before certain level it may lead to the target organ damage. This susceptibility of the target organ damage in grade 2 patients should be identified through research studies. This would be helpful to manage the condition effectively and in cost effective manner. Jim might have grade 2 hypertension, because he was diagnosed with type 2 diabetes mellitus and atherosclerosis. In grade 2 hypertensive patients, there is moderate to high rise in blood pressure accompanied by at least two target organ damage. Hence in these patients antihypertensive drugs like ACE inhibitors or angiotensin II receptor blocker s or beta blockers or calcium channel blockers or renin inhibitors can be used (Varounis et a., 2017; Yoon et al., 2015). Along with antihypertensive drugs, there should be administration of medication for target organ pathology. In patients with hypertension associated with atherosclerosis, there should be administration of statins which lowers levels of cholesterol. For Jim also, Lipitor was prescribed. Moreover, there was clear indication of organ damage in Jim. Patients with grade 3 hypertension are apparently associated with the target organ damage. Patients of this category generally exhibit sustained cardiovascular events irrespective of the level of blood pressure. Aging and association of other risk factors generally exaggerate condition of the grade 3 hypertensive patients and it may lead to the morbidity and mortality. Special emphasis should be given for reducing cardiovascular risk factors in grade 3 hypertensive patients. In patients with grade 3 hypertension, emergency antihypertensive drugs like nitrates should be administered along with the other antihypertensive drugs. In addition, medications for other risk factors should be administered in patients with grade 3 hypertension. Modifiable features of hypertension comprises of smoking, physical activity, low density lipoprotein (LDL), triglyceride levels, obesity, body mass index (BMI), diabetes mellitus and psychological stress. Non-modifibale features of hypertension comprises of family history, age, gender and genetic factors (Materson et al., 2014). Nurse should set different goals for Amanda and Jim. Nurse should set goal for Amanda to reduce her blood pressure to SBP 130-149 or DBP 80-89. Nurse should set goal for Jim to reduce his blood pressure to SBP 140-159 7or DBP 90-99. Nurse should set goal for Jim to reduce his cardiovascular complications and manage his type 2 diabetes mellitus condition. Nurse should give special attention for diastolic pressure in case of Jim because there should not be more reduction in diastolic pressure in patients with diabetes. Educational Plan: Food Nurse should educate Amanda and Jim for dietary habit to control hypertension. Nurse should advise them to eat food comprising of fruits, vegetable, whole grains, low-fat dairy products and fish. Nurse should advise them to consume more amount of potassium and fewer amounts of saturated fats. Specifically Jim, should avoid sugar containing products and food containing saturated fatty acids because he was diagnosed with type 2 diabetes mellitus and atherosclerosis. Nurse should prepare diet plan for Amanda and Jim, in consultation with dietician. These products exaggerate blood pressure in hypertension patients. Nurse should advise them to consume not more than 2000 mg per day salt because salt has negative impact on hypertension and its related risks like diabetes and kidney disease (Chen et al., 2014, Khan et al., 2014). Physical exercise Nurse should advise them to keep control on their body weight. Due to increase in body weight, BMI also can increase. Increased BMI is one of the prominent risk factor for the hypertension. Amanda should give special attention to control her body weight because her BMI is 28. BMI in this range indicates, Amanda is overweight. For maintaining optimum body weight both Amanda and Jim should increase their physical activity. Amanda should be very particular about physical activity because she should reduce her body weight. Amanda and Jim should perform approximately 150 minutes aerobic activity per week. Physical activity on the regular basis would be helpful for Amanda and Jim for controlling hypertension, managing stress due to increased blood pressure, reducing risks associated with hypertension and reducing body weight. Nurse should prepare exercise schedule for Amanda and Jim in consultation with exercise physiologist (Lauziere et al., 2013; Zinat Motlagh et al., 2015). Smoking and alcohol consumption Nurse should advise them to avoid alcohol because alcohol can increase blood pressure in normal persons also. Nurse should advise them to avoid smoking because smoking can produce injuries to blood vessels and facilitate hardening of the blood vessels (Lauziere et al., 2013; ; Zinat Motlagh et al., 2015) Psychological education Nurse should advise them to live stress free life. They should practice muscle relaxation and deep breathing for living stress free life. Physical activity and sufficient sleep also would be helpful in reducing stress (Lauziere et al., 2013; ; Zinat Motlagh et al., 2015) Blood pressure monitoring Nurse should teach them to monitor blood pressure at home. She should educate them to check blood pressure prior to and after medications. Nurse should incorporate cardiovascular technologist for teaching them measurement of blood pressure. This would be helpful in assessing effectiveness of medications. Nurse should also advise them to consult doctor immediately, if they observed noteworthy variation in their blood pressure (Lauziere et al., 2013) Social education Both Amanda and Jim should link themselves to the different community healthcare societies. In these societies they can share their experience and gain knowledge about the disease. It would be helpful for them for self management of the disease. It would also be helpful in relieving psychological issues like stress and burden of the disease. They should consult social worker to get link themselves to community healthcare societies (Park et al., 2011). Education about Lipitor and Avapro Nurse should educate Jim for Lipitor consumption. Nurse should advise him to take this drug once daily at the same time every day. Nurse should advise him to take regular blood tests for cholesterol and triglycerides. Nurse should also advise him to take liver function test. Nurse should advise him to inform healthcare provider about Lipitor consumption, if doctor wishes to prescribe him medicines for acute illness. Nurse should inform him that there may be nausea, vomiting and joint pain due to consumption of this medication. Nurse should tell him that, he should report muscle pain, weakness, fever, swelling and change in color of urine during consumption of Lipitor (Barber et al., 2012). Nurse should educate Amanda that she should not consume Avapro, if she has diabetes. Nurse should tell her that she should not use Avapro, if she is dehydrated. Nurse should inform her that she should monitor blood pressure on regular basis during consumption of Avapro. If she didnt find improvemen t in blood pressure, she should consult doctor. She should not stop taking Avapro, even if she found improvement in her blood pressure. She should keep Avapro away from heat and light. Nurse should tell her that she should stop alcohol and potassium supplements while taking Avapro. Both Amanda and Jim should consult pharmacist to get more information about their respective drugs (Barber et al., 2012). Conclusion: In Australia, highest number of treatments at general practitioners is for hypertension. Male are more affected with hypertension as compared to the female. There are different treatment options are available for different grades of hypertension. Along with medications use change in food habit and lifestyle should be incorporated in the management of hypertension. Amanda and Jim are having different grade of hypertension. There should be different goals and education plan for Amanda and Jim in hypertension management. With effective implementation of medical, social, psychological and physical interventions, hypertension in Amanda and Jim can be effectively controlled.

Air Water Soil Noise Pollution Essay Example

Air Water Soil Noise Pollution Paper Then a non-nuclear event, The Great Smog of 1952 in London, killed at least 4000 people. This prompted some of the first major modern environmental legislation, The Clean Air Act Of 1956. Air pollution Air pollution is the introduction of chemicals, particulate matter, or biological materials that cause harm or discomfort to humans or other living organisms, or damages the natural environment into the atmosphere. The atmosphere is a complex dynamic natural gaseous system that is essential to support life on planet Earth. Stratospheric ozone depletion due to air pollution has long been agonized as a threat to human health as well as to the Earths ecosystems. Pollute ants An air pollutant is known as a substance in the air that can cause harm to humans and the environment. Pollutants can be in the form of solid particles, liquid droplets, or gases. In addition, they may be natural or man-made. Pollutants can be classified as either primary or secondary. Usually, primary pollutants are substances directly emitted from a process, such as ash from a volcanic eruption, the carbon monoxide gas from a motor vehicle exhaust or sulfur dioxide released from factories.

Rather, they form in the air when primary pollutants react or interact. An important example of a secondary pollutant is ground level ozone -? one of the many secondary pollutants that make up photochemical smog. Major primary pollutants produced by human activity include: Sulfur oxides (SOX) especially sulfur dioxide, a chemical compound with the formula SIS. SIS is produced by volcanoes and in various industrial processes. Since coal and petroleum often contain sulfur compounds, their combustion generates sulfur dioxide. Further oxidation of SIS, usually in the presence of a catalyst such as NON, forms HOSES, and thus acid rain. [2] This is one of the causes for concern over the environmental impact of the use of these fuels as power sources. Nitrogen oxides (Knox) especially nitrogen dioxide are emitted from high temperature combustion. Can be seen as the brown haze dome above or plume downwind of cities. Nitrogen dioxide is the chemical compound with the formula NON. It is one of the several nitrogen oxides. This reddish-brown toxic gas has a characteristic sharp, biting odor. NON is one of the most prominent air pollutants. Carbon monoxide is a colorless, odorless, non- irritating but very poisonous gas. It is a product by incomplete combustion of fuel such as natural gas, coal or wood. Vehicular exhaust is a major source of carbon monoxide. Carbon dioxide (CO) a greenhouse gas emitted from combustion but is also a gas vital to living organisms. It is a natural gas in the atmosphere. Odors such as from garbage, sewage, and industrial processes Radioactive pollutants produced by nuclear explosions, war explosives, and natural processes such as the radioactive decay of radon. Secondary pollutants include: Particulate matter formed from gaseous primary pollutants and compounds n photochemical smog. Smog is a kind of air pollution; the word smog is a portmanteau of smoke and fog. Classic smog results from large amounts of coal burning in an area caused by a mixture of smoke and sulfur dioxide. Modern smog does not usually come from coal but from vehicular and industrial emissions that are acted on in the atmosphere by sunlight to form secondary pollutants that also combine with the primary emissions to form photochemical smog. Ground level ozone (03) formed from Knox and Voss. Ozone (03) is a key constituent of the troposphere (it is also an important institutes of certain regions of the stratosphere commonly known as the Ozone layer). Photochemical and chemical reactions involving it drive many of the chemical processes that occur in the atmosphere by day and by night. At abnormally high concentrations brought about by human activities (largely the combustion of fossil fuel), it is a pollutant, and a constituent of smog. Approximately nitrate (PAN) similarly formed from Knox and Voss. Minor air pollutants include: A large number of minor hazardous air pollutants. Some of these are regulated in USA under the Clean Air Act and in Europe under the Air Framework Directive. A variety of persistent organic pollutants, which can attach to particulate matter. Persistent organic pollutants (Pops) are organic compounds that are resistant to environmental degradation through chemical, biological, and photolytic processes. Because of this, they have been observed to persist in the environment, to be capable of long-range transport, fasciculate in human and animal tissue, abominating in food chains, and to have potential significant impacts on human health and the environment. Health effects of Air Pollution: The World Health Organization states that 2. 4 million people die each year room causes directly attributable to air pollution, with 1. 5 million Of these deaths attributable to indoor air pollution. Worldwide more deaths per year are linked to air pollution than to automobile accidents. Direct causes of air pollution related deaths include aggravated asthma, bronchitis, emphysema, lung and heart diseases, and respiratory allergies. The worst short term civilian pollution crisis in India was the 1 984 Opal Disaster. Leaked industrial vapors from the union Carbide factory, belonging to Union Carbide, Inc. , U. S. A. , killed more than 2,000 people outright and injured any. Inhere from 50,000 to 600,000 others, some 6,000 of whom would later die from their injuries. The United Kingdom suffered its worst air pollution event when the December 4 Great Smog of 1 952 formed over London. In six days more than 4,000 died, and 8,000 more died within the following months Water pollution Water pollution is the contamination of water bodies (e. G. Lakes, rivers, oceans, groundwater). Water pollution affects plants and organisms living in these bodies of water; and, in almost all cases the effect is damaging not only to individual species and populations, but also to the natural biological communities. Water pollution occurs when pollutants are discharged directly or indirectly into water bodies without adequate treatment to remove harmful compounds. Causes of water pollution The specific contaminants leading to pollution in water include a wide spectrum of chemicals, pathogens, and physical or sensory changes such as elevated temperature and disconsolation. While many of the chemicals and substances that are regulated may be naturally occurring (calcium, sodium, iron, manganese, etc. ) the concentration is often the key in determining what is a natural component of water, and what is a contaminant. Oxygen- depleting substances may be natural materials, such as plant matter (e. G. Leaves and grass) as well as man-made chemicals. Other natural and anthropogenic us absences may cause turbidity (cloudiness) which blocks light and disrupts plant growth, and clogs the gills of some fish species. Many of the chemical substances are toxic. Pathogens can produce waterborne diseases in either human or animal hosts. Effects of Water Pollution Water pollution is a major problem in the global context An estimated 700 million Indians have no access to a proper toilet, and 1,000 Indian children die f diarrhea sickness every day. Some 90% of Chinas cities suffer from some degree of water pollution, and nearly 500 million people lack access to safe drinking water. Chemical and other contaminants Organic water pollutants include: Detergents Disinfection by-products found in chemically disinfected drinking water, such as chloroform Food processing waste, which can include oxygen-demanding substances, fats and grease Insecticides and herbicides, a huge range of organogenesis and other chemical compounds Petroleum hydrocarbons, including fuels (gasoline, diesel fuel, jet fuels, and fuel oil) and lubricants motor oil), and fuel combustion byproducts, from stemware runoff[1 5] Tree and bush debris from logging operations Volatile organic compounds (Voss), such as industrial solvents, from improper storage. Chlorinated solvents, which are dense non-aqueous phase liquids (Donald), may fall to the bottom of reservoirs, since they dont mix well with water and are denser. Various chemical compounds found in personal hygiene and cosmetic products Inorganic water pollutants include: Acidity caused by industrial discharges (especially sulfur dioxide from power plants) Ammonia from food processing waste Chemical waste as industrial by-products Fertilizers containing nutrientsnitrates and phosphates-?which are found in stemware runoff from agriculture, as well as commercial and residential use[1 5] Heavy metals from motor vehicles (via urban Stemware runoff)[1 5]CO 6] and acid mine drainage Silt (sediment) in runoff from construction sites, logging, slash and burn practices or land clearing sites Land pollution Please help improve this article by adding citations to reliable sources. Unsounded material may be challenged and removed. Land pollution is the degradation of Earths land surfaces often caused by human activities and their misuse of land resources. It occurs when waste is not disposed properly. Health hazard disposal of urban and industrial wastes, exploitation of minerals, and improper use of soil by inadequate agricultural practices are a few factors. Arbitration and industrialization are major causes Of land pollution. Increased mechanization The major increase in the concentration of population in cities, along with the internal combustion engine, led to the increased number of roads and all the infra structure that goes with them. Roads cause visual, noise, light, air and water pollution, in addition to land pollution. The visual and noise areas are obvious, however light pollution is becoming more widely recognized as a problem. From outer space, large cities can be picked out at night by the glow of their lighting so city dwellers seldom experience total darkness. As the demand for food has grown very high, there is an increase in field size and mechanization. The increase in field size makes it economically viable for the farmer but results in loss of person and shelter for wildlife, as hedgerows and copses disappear. When crops are harvested, the naked soil is left open to wind after the heavy machinery has compacted it. Another consequence of ore intensive agriculture is the move to monoculture. This is unnatural, it depletes the soil of nutrients, allows diseases and pests to spread and, in short, brings into play the use of chemical substances foreign to the environment. A pesticide is a substance or mixture of substances used to kill a pest. A pesticide may be a chemical substance, biological agent (such as a virus or bacteria), antimicrobial, disinfectant or device used against any pest. Pests include insects, plant pathogens, weeds, mollusks, birds, mammals, fish, nematodes (roundworms) and microbes that compete with humans for food, story property, spread or are a vector for disease or cause a nuisance. Although there are benefits to the use of pesticides, there are also drawbacks, such as potential toxicity to humans and other organisms. Pesticides are used to control organisms which are considered harmful. For example, they are used to kill mosquitoes that can transmit many potentially deadly diseases like west Nile virus, yellow fever, and malaria disease. They can also kill bees, wasps or ants that can cause allergic reactions. Insecticides can protect animals from illnesses that can be caused by parasites such as fleas. Suicides can prevent sickness in humans that could be caused by moldy food or diseased produce. Mining Modern mining projects leave behind disrupted communities, damages landscapes, and polluted water. Mining also affects ground and surface waters, the aquatic life, vegetation, soils, animals, and the human health. Acid mine drainage can cause damage to streams which in return can kill aquatic life. The vast variety of toxic chemicals released by mining activities can harm animals and aquatic life as well as their habitat. The average mine disturbs over a thousand acres Of land. Construction See the bodies of water. Doing this, natural water filters are damaged. Natural water filters help break down many pollutants before they reach other water bodies. Some that may run off with water and sediments from construction sites are oils, debris, and paint. This can cause damage to soil, aquatic life, and promote hazardous chemicals to get into drinking water. Effects A large percentage of material that is dumped into waters not only destroys habitats for animals but for humans as well. Below is a list of some impacts of land pollution. There are some habitats, where aquatic animals feed and live, o there is a risk of destruction of habitat of aquatic animals. Reduced oxygen levels from decomposition of organic material dumped from drains. Reduced light penetration in the water column, from sediments and excessive algal growth, leading to oxygen depleted water. *Massively changed flow regimes, large fast flows can scour existing habitat and wash species downstream. Increased human health risks, from syringes, broken glass and cans washing onto creek banks and beaches. Reduced aesthetic appeal of areas from litter strewn on banks and beaches, thus reducing recreation and tourist appeal. Acid rain damages trees and other plants. Noise pollution Noise pollution (or environmental noise) is displeasing human, animal or machine-created sound that disrupts the activity or balance of human or animal life. The word noise comes from the Latin word nauseas meaning seasickness. The source of most outdoor noise worldwide is mainly construction and transportation systems, including motor vehicle noise, aircraft noise and rail noise. [1][2] Poor urban planning may give rise to noise pollution, since side-by-side industrial and residential buildings can result in noise pollution in the residential area. Indoor and outdoor noise pollution sources include car alarms, emergency service sirens, mechanical equipment, fireworks, compressed air horns, groundskeepers equipment, barking dogs, appliances, lighting hum, audio entertainment systems, electric megaphones, and loud people. Human health effects Noise health effects are both health and behavioral in nature. The unwanted sound is called noise. This unwanted sound can damage physiological and psychological health. Noise pollution can cause annoyance and aggression, hypertension, high stress levels, tinnitus, hearing loss, sleep disturbances, and other harmful effects. Furthermore, stress and hypertension are the leading causes to health problems, whereas tinnitus can lead to forgetfulness, severe depression and at times panic attacks. Environmental effects Noise can a detrimental effect on animals by causing stress, increasing risk of death by changing the delicate balance in predator/prey detection and avoidance, and by interfering with their use Of sounds in communication especially in relation to reproduction and in navigation. Acoustic overexposure can lead to temporary or permanent loss of hearing. An impact of noise on animal life is the reduction of usable habitat that noisy areas may cause, which in the case of endangered species may be part of the path to extinction. Noise pollution has caused the death of certain species of whales that beached themselves after being exposed to the loud sound of military sonar. Pollution control Pollution control is a term used in environmental management. It means the control of emissions and effluents into air, water or soil. Without pollution control, the waste products from consumption, heating, agriculture, mining, manufacturing transportation and other human activities, whether they accumulate or disperse, will degrade the environment.

Caleb’s Crossing by Geraldine Brooks Essay Example

Caleb’s Crossing by Geraldine Brooks Essay Example Caleb’s Crossing by Geraldine Brooks Essay Caleb’s Crossing by Geraldine Brooks Essay Caleb’s Crossing, by Geraldine Brooks, explores the relationship between Bethia Mayfield, the daughter of a Puritan European colonist, and Caleb, the son of a Wompanog chieftain, as well as Caleb’s journey from being a Native American to learning European customs and ultimately getting an education at Harvard. Throughout the novel, Bethia is drawn to Caleb and his native culture, despite being apprehensive at first. This is because it is such an alien world to her and, shown as being a naturally curious person, she wants to learn more. She eventually finds Caleb to be a blank canvas for her to spread her ideals upon and to teach, since he had no prior experience with European customs and religion. Bethia is very drawn to Caleb because European concepts of religion and culture are so new to him. She even describes him as, â€Å"unschooled†1, showing her acknowledgement of his lack of modern education. During the secret times of their friendship, he questions her about her religion, â€Å"Only one god. Strange, that you English, who gather about you so many things, are content with one and only. And so distant, up there in the sky†2. In response to this, Bethia doesn’t say anything, mostly because she, â€Å"hardly knew what to say to one so lost†3. This is the moment that Bethia really realizes how different Caleb’s culture is from hers, and feels the desire to take him under her wing and share with him what education she has managed to attain despite her gender-based setbacks. The next day, Bethia shares one of her favorite books with Caleb, â€Å"He made me smile, opening it upside down and back to front, but he touched the pages with the utmost care the godliest among us did not tough the Bible with such reverence as he showed to that small book†4. This interaction shows how pleased Bethia is with herself for introducing Caleb to this new concept and how amused she is at his lack of European knowledge. It also shows how Caleb is

Nuisance ( torts law) - Essay Example hurt or annoyance of the lands, tenements, or hereditaments of another." The forms of private nuisances are almost countless, thus resulting in the impossibility of any kind of classification (Putney, 1908). A person who owns a proprietorship interest in the land in which nuisance is inflicted can sue and succeed to claims. For instance the person must be an owner or a party, or be in special custody or occupation of it like tenant or under a licence to reside. Exceptions to the above rule may also be present as in the case of Hunter v Canary Wharf.1 The case of Malone v Laskey2 is an exception of the rule that a licensee can sue. In the mentioned case when the wife of the licensee used the toilet a cistern fell on her head due to the trembling of machinery in the nearby property and she was hurt. But when she claimed it failed because her husband was only a licensee and so it could not be proved that she held a proprietary interest in the land herself. But had this case been occurred now she would have succeeded under negligence. But an exception to this is that the wife of a home owner can sue since she also has a beneficial interest in the matrimonial home Hunter v Canary Wharf. Actually according to law jus tertii meaning right of a third person, is not a good defence to sue in a private nuisance. But if a person is in exclusive possession of the land can sue even if title to it cannot be proved Foster v Warblington.3 Till very lately it was resolved, that the complainant must have an interest in the land so that he could sue in private nuisance. But then in the case of Khorasandijian v. Bush4 it was in particular affirmed that it was no longer suitable to restrict the right to sue by indication to proprietary interest in the land. In this case Lord Dillon said the following†¦Ã¢â‚¬ it is ridiculous if in this present age the law that is the making of deliberately harassing and pestering phone calls to a person is only actionable in the civil courts if a
