Acid Rain Essays (1959 words) - Inorganic Solvents, Acid Rain

Acid Rain INTRODUCTION: Acid rain is a great problem in our world. It causes fish and plants to die in our waters. As well it causes harm to our own race as well, because we eat these fish, drink this water and eat these plants. It is a problem that we must all face together and try to get rid of. However acid rain on it's own is not the biggest problem. It cause many other problems such as aluminum poisoning. Acid Rain is deadly. WHAT IS ACID RAIN? Acid rain is all the rain, snow, mist etc that falls from the sky onto our planet that contains an unnatural acidic. It is not to be confused with uncontaminated rain that falls, for that rain is naturally slightly acidic. It is caused by today's industry. When products are manufactured many chemicals are used to create it. However because of the difficulty and cost of properly disposing of these products they are often emitted into the atmosphere with little or no treatment. The term was first considered to be important about 20 years ago when scientists in Sweden and Norway first believed that acidic rain may be causing great ecological damage to the planet. The problem was that by the time that the scientist found the problem it was already very large. Detecting an acid lake is often quite difficult. A lake does not become acid over night. It happens over a period of many years, some times decades. The changes are usually to gradual for them to be noticed early. At the beginning of the 20th century most rivers/lakes like the river Tovdal in Norway had not yet begun to die. However by 1926 local inspectors were noticing that many of the lakes were beginning to show signs of death. Fish were found dead along the banks of many rivers. As the winters ice began to melt off more and more hundreds upon hundreds more dead fish (trout in particular) were being found. It was at this time that scientist began to search for the reason. As the scientists continued to work they found many piles of dead fish, up to 5000 in one pile, further up the river. Divers were sent in to examine the bottom of the rivers. What they found were many more dead fish. Many live and dead specimens were taken back to labs across Norway. When the live specimens were examined they were found to have very little sodium in their blood. This is typical a typical symptom of acid poisoning. The acid had entered the gills of the fish and poisoned them so that they were unable to ext ract salt from the water to maintain their bodies sodium levels. Many scientist said that this acid poising was due to the fact that it was just after the winter and that all the snow and ice was running down into the streams and lakes. They believed that the snow had been exposed to many natural phenomena that gave the snow it's high acid content. Other scientists were not sure that this theory was correct because at the time that the snow was added to the lakes and streams the Ph levels would change from around 5.2 to 4.6. They believed that such a high jump could not be attributed to natural causes. They believed that it was due to air pollution. They were right. Since the beginning of the Industrial revolution in England pollution had been affecting all the trees,soil and rivers in Europe and North America. However until recently the loses of fish was contained to the southern parts of Europe. Because of the constant onslaught of acid rain lakes and rivers began to lose their ability to counter act their affects. Much of the alkaline elements; such as calcium and limestone; in the soil had been washed away. It is these lakes that we must be worried about for they will soon become extinct. A fact that may please fishermen is that in lakes/rivers they tend to catch older and larger fish. This may please them in the short run however they will soon have to change lakes for the fish supply will die quickly in these lakes. The problem is that acid

A Hospitality Operator Might Face - Assignment Example 4.) Factors that contribute to the bleakness and roughness of hospitality laws especially in the past were the small number of inns in which the innkeeper took the advantage of controlling the hospitality business. The hospitality law is considered as the foremost protector of the entire guests in this business (Cournoyer, et al., 2008). At present, there are already several establishments within the industry, and the presence of stiff competition is one determining factor for this occurrence (Cournoyer, et al., 2008). The nature of the hospitality management comprises the inclusion of the provision of services accommodation in the food and beverages business within a wide range of service establishments (Pizam, 2005, p. 53).These establishments include hotels, motels, clubs, casinos, restaurants, fast food outlets, and bars, to name a few. Hospitality management has also started growing inside shipping companies, rails, schools, hospitals, and so on (Pizam, 2005). Tourists are consi dered as the main factor why the hospitality business continues to develop and grow. It must be noted that the hospitality business provides the wider range of employment among people in both the rural and urban areas. 2. Worker Violence as a Legal Problem that a Hospitality Operator Might Face The hospitality operator is never exempted from encountering legal problems in hospitality management. ... Worker violence is identified in this paper as a legal problem that might be faced by the hospitality operator. Homicide appears to be one of the most extreme forms of violence manifested in the hospitality workplace (O’Fallon and Rutherford, 2011). According to US Department of Labor Occupational Safety and Health Administration (1998), homicide is the second cause of death of Americans working in the hospitality management. In 1996, data revealed that 912 workers account to the total work injuries in the US alone, indicating the seriousness of the homicide cases in the hospitality sector. A survey made by the National Crime Victimization of the Department of Justice indicates that there are about one million victims of violent crime at work, spanning from 1987 to 1992. Four categories are included in these data, specifically simple assault (615,160 victims); aggravated assault (264,174 victims); robbery (79,109 victims); and rape (13,068 victims). It appears that 159,000 cas es of victimization are reported annually in the hospitality business (US Department of Labor Occupational Safety and Health Administration, 1998). In 2002, 52 per cent of the service sector in 347 workplaces in the United States hospitality management has been a victim of homicide, according to the department of labor (O’Fallon and Rutherford, 2011, p. 229). Violence in the hospitality workplace is identified in two categories. Explicit violence, in which such violence directly involves the employees of a particular establishment, and implicit violence, in which the violence is specifically directed to the establishment (O’Fallon and Rutherford, 2011). The hospitality operator indeed faces a serious problem with the possibility of workplace violence occurring within his or her

Literature review - Essay Example The health care industry in any given country is as much a system and an industry. In the case of Australia, the health care system is not managed hierarchically. It is not also designed centrally by the government. The participants in the health care in Australia, namely the consumers and the providers, do enjoy a great degree of autonomy and independence. Nonetheless, the health care system occupies an important portion in the Gross Domestic Product (GDP) of Australia—the health care sector currently accounts for 9.7% of this GDP (Podger, 2005, p. 1). In spite of the degree of freedom enjoyed by health care practitioners and recipients, the government still plays a large part in the industry. According to Podger (2005, p. 1-2), the objectives of the health care system are (1) good health for the citizens; (2) health care is equitable, meaning it is available and accessible to all citizens, taking into account their capacity to pay; (3) costs reasonably low; and (4) the satisfaction of consumers and of health care professionals. To meet these objectives, the government, inevitably intervenes. In the interest of promoting equity, the government reallocates its resources to meet the needs of the population. Secondly, health has several features that involve public goods; as such, the government is also involved in the prevention of diseases and the safety of foods and drugs. The role of the government becomes especially important because of market failures as well as the provision of asymmetric or incomplete information. Especially in the case of the health insurance industry, the government steps in to regulate the industry so that the consumers are protected and are given the health care they need at the right cost (Podger, 2005, p. 3). Yet, in order for the health care system to be efficient and for it to become accessible to all sectors, both the public and the
