Effects of Acid Rain on Ecosystems essays

Effects of Acid Rain on Ecosystems essays In the past century, one of the greatest threats to North America's aquatic ecosystem has been the widespread acidification of hundreds of thousands of waterways. Acid rain has effected plant and animal life within aquatic ecosystems, as well as microbiologic activity by affecting the rates of decomposition and the accumulation of organic matter. What causes this poisonous rain, and what can be done to improve North America's water quality and prevent future catastrophes? To answer these questions, we must first examine the cause and formation of acid rain, as well as understand ways to decrease or prevent its formation. Acid deposition, more commonly known as acid rain, occurs when emissions of sulfur dioxide (SO2) and nitrogen oxides (NOx) react in the atmosphere with water, oxygen, and oxidants to form acidic compounds. This mixture forms a mild solution of sulfuric and nitric acid which then falls to the earth in either wet (rain, snow, sleet or fog) or dry (gas and particles) form. Approximately one-half of the atmosphere's acidity falls back to earth through dry deposition in the form of particles and gases, and are then spread hundreds of miles by winds where they settle on surfaces of buildings, cars, homes, and trees. When acid rain falls, the dry deposited gases and particles are sometimes washed from buildings, trees and other surfaces making the runoff water combine with the acid rain more acidic than the falling acid rain alone. This new combination is referred to as acid deposition. Strong prevailing winds and public sewer systems into lakes and streams then transport the runoff water. Although some natural sources such as volcanic eruptions, fire and lightening contribute to the emissions of sulfur dioxide and nitrogen oxides in the atmosphere, more than 90% is the result of human activities such as coal burning, smelting of metals such as zinc, nickel and copper, and the burning of oil, coal and gas in power plants...

Anti-Terror Laws - What Americ essays

Anti-Terror Laws - What Americ essays Anti-Terror Laws - What Americans Should Know Unaware to most people in the US, recently passed laws allow the government to watch them just about as much as they want. After the tragic terrorist attacks of September 11th, 2001 there have been many laws passed to protect our nation from these terrible people. In the process of trying to protect us, the citizens of the United States, they have started to pry into our lives. Making some uncomfortable. Many people believe there are too many flaws and that these new laws can give the government too much access to our lives. The main laws that have passed include the USA Patriot Act, the Homeland Security Act, and a possible Domestic Security Enhancement Act, currently in draft form. I am not saying do away with these laws, but they should be revised, reconsidered, and then put back into place. Initially, the USA Patriot Act was passed by an overwhelming vote by the US Congress on October 26, 2001. This act was passed very quickly after the 9/11 attacks, it is considered a weaker version of the upcoming Homeland Security Act. This law allows the FBI to begin spying on American's that were considered a threat. There was judicial over-sight established in the 70's to stop this. Some of the FBI and CIA monitoring affect a lot of areas of typical American's lives. Internet usage can be spied on if a law enforcement agent believes that surveillance is "relevant" in an ongoing investigation. When a person signs on to the internet they send and receive "packets" of information and that creates what comes up on the screen and this is what a user interacts with. New government software named Carnivore is included in the expanded investigative powers included in this act. This software "sniffs" these packets for key words or e-mail addresses that have become deemed a threat by investigators. FBI now can obtain access to many sensitive documents about a person's life just by sta...

If official corruption is such a problem for the legitimacy of the Essay

If official corruption is such a problem for the legitimacy of the People's Republic of China, then why have the Chinese Commu - Essay Example The main reasons why PRC has waged war against corruption is the fact that it undermines the legitimacy of the Chinese Communist party, it fuels societal unrest, and adds to the economic inequality in the country. If the communist party does not formulate policies that will contain the wide spread corruption in China, then it will be spelling doom for the economic future of the country and the political stability too. Analysis and Causes As pointed out earlier, the major forms of corruption in the PRC are embezzlement of funds, bribery, nepotism, statistical falsification, patronage, backdoor deals, and grafts.All these are common and rampant in power positions. This explains why the standard definition of corruption in China is the use of public authority and resources for personal and private interests. When any state functionary takes advantage of their office and appropriates, steals, or swindles public money, or takes it in to their possession by any other illegal means, then it is said that corruption has occurred. Moreover, when a state functionary extorts money or property from an individual for the benefit of another person or illegally accepts money from a person in order to secure benefits for that individual, or the state functionary misappropriates public funds for either personal use, illegal dealings, or for profit making purposes, then corruption has occurred. If any citizen gives money or property to a state functionary, or introduces a bribe to them for the purpose of securing certain benefits, then the two can be accused of being involved in corrupt dealings. All these occurrences are in accordance with articles 382 and 396 of the criminal law of the People’s Republic of China. Combating corruption has been a main agenda for the Chinese Communist Party (CCP) over the last three decades with every transition of government. During this period, two major anti-corruption campaigns were launched; one in the late 1970’s, and the other in 1989 following the Tiananmen crackdown on the pro-democracy movement. This paper will mainly focus on the 1989 campaign and all other attempted reforms that followed as they fall under the 25 year period that is under study. The efforts of China to eradicate poverty are often frustrated by the enforcement constrains in the country. The CCP employed a strategy dubbed enforcement swapping. This strategy relied on intensive periodic campaigns which were targeted at the big fish. This strategy was credited to have successfully lowered the levels of corruption beyond the tipping point; a point which if surpassed, would have resulted in to a crisis of corruption and overwhelmed the parties enforcement resources (Manion, 2004. P.158). This strategy is said to have been employed out of necessity simply because the CCP lacked enforcement resources and the capacity to wipe out corruption. According to Wedeman, (2004,p.899), the campaign style of enforcement is aimed at controlling corrupt ion rather than eradicating it. This is irrespective of the manner in which it is used; randomized or recreational. This is the very first reason why attempts to eradicate corruption in China by CCP have failed. The communist’s party strategy to eradicate poverty was misguided simply because this strategy is formulated to specifically control corruption, not eradicate it. There is also the probability that the CCP knew exactly what the strategy was

Medical Apartheid Essay Example | Topics and Well Written Essays - 500 words

Medical Apartheid - Essay Example Admittedly, remedial steps are being taken on the government level to counter barriers mentioned above.A study was carried out by the National Institute of Health to recheck why disparity occurred in this drug’s efficacy for blacks and Asians but not whites. This research concluded that this was most likely a result chance. Even if there was a small possibility that this drug actually did hold some hope for HIV patients, especially blacks, it definitely called for further research and testing. The reason mostly given for not carrying out further research is that blacks are resistant to being subjects for testing, especially for HIV. However, many researchers have been successful in recruiting a large number of blacks for their work. This clearly implies that there is need for more trust and empathy for blacks to cooperate. It is the right of the African Americans to have more research conducted into AIDSVAX as they do represent the majority of sufferers of this disease. Furthermore, if this drug does indeed prove to be primarily applicable to blacks, these differences will most likely be environmental; even if the differences are determined to be somewhat racial, one successful drug could be made adaptive to whites with further work. The world indeed sits in wait of a miracle drug that could cure the ‘incurable’ AIDS. So far, AIDSVAX is the only drug that has come closest to being it. Our country has a battle with itself right now of overcoming this discrimination against race and color for common good.

Human Resources Assignment Example | Topics and Well Written Essays - 1500 words

Human Resources - Assignment Example ACAS encourages employees to appeal against unfair dismissals and employers can only lay off workers if there is an existing contractual agreement between he employer and the employer. Accordingly, the redundant temporary employees are entitled to statutory guaranteed payments that include up to five days pay in any three-month period (CIPD 2013). ACAS advocates for an ad-hoc approach, formal policies or formal agreements with trade unions as the possible approaches of implementing redundancies in the organization. The fixed term employment contracts than naturally end will be excluded from the obligations to engage in collective consultations (ACAS 2013). The Chartered Institute of Personnel and Development (CIPD) require fair selection of employees to be put on redundancy and collective consultations before the redundancy (CIPD 2013). According to CIPD, redundancy rights and obligations are governed by the employment rights act 1996, the Trade union and labour relations (consolidat ion) Act 1992, protection of employment regulations 1995, collective redundancies and the transfer of undertaking (amendment) regulations 1999 and finally collective redundancies (amendment) regulations 2006. ... The concerned employees are eligible for certain rights such as redundancy pay, a reasonable notice period, discussions with the employer and some time off to seek alternative employment (Gilmore and Williams 2012). The redundancy must be fair and discriminatory practices such as age, disability or gender cannot be utilized as the criteria for redundancy (Gilmore and Williams 2012). The redundancy entails more than 20 employees thus Dan Findale must adhere to the redundancy procedure outlined in ACAS code of practice on redundancy consultation process. Accordingly, protection of employment Act 1977-2007 requires the employers to enter in to consultations with the employees at least 30 days before the first redundancy occurs. In addition, the employees (provision of information and consultation) Act 2006 requires the employers with at least 50 employees to enter in to consultations with employees before any changes in workplace including the proposals for collective redundancy (ACAS 2 013). According to the case study, Dan Findale intends to make the 23 employees redundant thus, redundancy is just a dismissal that is not related to the individual employee or the capability of the individual employee, but an overall reorganization of the staff without recruiting new staff. Dan will have to justify his intentions of cost reduction in order to ensure the survival of the charity operations. Dan Findale must follow fair criteria in determining the employees to be made redundant. Some common criteria include last in, first out method that aims at preserving knowledge, skills and experience, staff appraisal rankings and asking for volunteers (Gilmore and Williams 2012). Unfair selection methods such as previous participation in industrial activities,
