Enviornmental law - Coursework Example The Earth Day 1970 marked a turning point in the Americans’ awareness about the environmental problems. The Congressional enactment of the Clean Air Act that year, just a few months after the Earth Day was a great landmark. These amendments moved the environmental protection concerns to a prominent position on Capitol Hill where it remained to date (Paul, 1990). The fact that the Earth Day and the 1970 amendments took place almost at the same time was no accident. The amendments of this law actually took place as a result of Congress’s response to the long time public concern about the environmental pollution which was symbolized by the Earth Day demonstrations. Through the public pressure, the Congress then went through a rush to come up with the legislation that would ensure protection against pollution. The original version of this Act which was passed by the U.S Congress in 1970 was fairly straightforward. This placed the EPA in charge of monitoring and improving th e nation’s air quality. Under this Act, the EPA had the power to establish research programs, set clean air standards, enforce regulations, and provide technical and financial assistance to state and local government efforts towards reducing air pollution. This Act also directed the EPA to establish the National Ambient Air Quality Standards (NAAQS) that could be useful in controlling emissions of a number of substances that threatened air quality. The NAAQS then divided pollutants into 2 categories, with the first category consisting of those that directly affect human health, and the second category included those that affected human welfare. This Act underwent significant changes and amendments in 1990. The revisions specifically targeted acid rain, with the aim of reducing emissions sulfur dioxide and Nitrogen Oxides by half. There were also new limits to ozone which is the main contributor to smog in urban areas. Some of the benefits associated with this Act include, but not limited to; 160,000 premature deaths avoided, 130,000 heart attack cases avoided, millions of acute respiratory cases avoided and also avoided 86,000 hospital admissions. It prevented 13 million lost workdays, kept kids healthy and in school avoiding 3.2 million lost school days. Between 1970 and 2011, the aggregate emissions of common air pollutants dropped by 68% while at the same time, the U.S gross domestic product grew by 212% (EPA, Benefits and Costs of the Clean Air Act, 2012). This Act has over the years, since it was passed, created a lot of economic impact in the Americans’ society. To begin with, there has been a dramatic reduction in air pollution rates that has protected the health of many American workers and their families. This is evident by fewer premature deaths and illness which shows that Americans experience longer lives, better quality of life, lower medical expenses, reduced school absences, and better work productivity. This means that the Act has been a good investment for Americans. It is evident that since 1970, cleaner air and growing of the economy has gone hand in hand. The pollution has since reduced by up to -72% while the economy has grown up to +219% as shown by the EPA. The data show the tremendous change that has resulted due to the implementation of the Act up to 2012 (EPA, 2012). The graphs were retrieved from the United States Environmental Protection Agency site at http://www.epa.gov/air/caa/ From the data above, one can easily deduce that the Act has greatly

Power and Politics Essay Example | Topics and Well Written Essays - 500 words

Power and Politics - Essay Example Other than being wife of Bill Clinton, Hillary had been a standing Senator for quite a few terms and had created an image of herself throughout the country through her ambitious dream of bringing each and every American under a comprehensive health scheme. Compared to that Obama was a first time Senator who had no political pedigree or lineage as such and above all, he was colored and had a Muslim sounding middle name and spent his childhood in far away Eastern countries. The odds were heavily stacked against Obama and truly nobody was prepared to give him much of a chance in the initial stages. But Obama and his clarion call â€Å"Yes, we can †¦Ã¢â‚¬  struck a chord among the masses, not only the colored ones but the entire American middle class and he created history. He derived his power essentially from referent base. Here was a man, just as ordinary as any American, has good education from Ivy League institutions, has a family just as most Americans have and above all, ha s a dream to change the sorry state of affairs. The combined charm of all these factors was too difficult for average Americans to be indifferent to. And, the fact that he is educated and articulate with a wife who is equally educated and articulate automatically vested in him an expert power that added to the huge faith that Americans reposed on him (Mind Tools 2005).

Professional Capstone Project - Essay Example To address this issue further clinical trials are essential and preventive health strategies addressing the established causative agents should be implemented. Lung cancer often results from the abnormal growth of the cells lining the passageway of the lungs. They can be dangerous as they can spread and invade other tissues of the body. Because of this it is one of the most common causes of cancer death worldwide. The disease has a very low prognosis, with less than 15% of the diagnosed patients surviving 5 years after diagnosis. The clinical signs and symptoms are often vague and non-specific Radiologic tests such as x-ray and CT scan often provides the usual indication of lung cancer. PET scan has been shown to be important in cancer staging. The role of diagnosis on the staging, treatment and management of lung cancer cannot be overemphasized, thus it is essential to understand the contributions and limitations of each diagnostic procedure. The signs and symptoms of lung cancer are often covert or if not, they mimic other respiratory infections. Radiologic techniques, especially X-ray and CT (computerized axial tomography) scan are the most preferred techniques for initial diagnosis, and yet both offer some advantages and drawbacks. X-ray could not determine small tumors, if detected the patient may be in the late stages thus making treatment more difficult and even impossible. CT scan is more sensitive, having the ability to determine even the smaller tumors and yet lacks the ability to resolve whether the tumor is benign or just an inflammation as a result of respiratory infection. Furthermore, CT scan has not reduced the mortality rate of lung cancer. Furthermore, CAT scans have not decreased the incidence of the disease (Spiro, 2007). Proper screening and diagnosis of any type of cancer is important in the staging and treatment.

Effects of Rapid Population Growth Essay Example for Free

Effects of Rapid Population Growth Essay While population growth is at times a beneficial thing for a species, there are many factors that define when growth becomes detrimental. When population growth becomes rapid there is a great chance that the counter-productive level has been reached. The most accurate index is the balance between population and sustainability. 1. Rapid Growth oRapid growth is a quick increase in population. The number concerned when calculating the population is the number of individuals alive. In other words, while some areas may have large numbers of births, they may not realize an increase in their population if the death rate is sufficient to offset the birthrate. These sort of factors can actually contribute to birth rates and the rate of growth. For example, in times when populations have experienced great losses, a rapid increase in population may occur. In these situations this may be termed a correction (this is a statistical concept). The Baby Boom following World War II is an instance of this sort. Causes There can be a variety of causes for rapid population growth. There are circumstances which can create sentiment in the population that will inspire population growth. These are usually immediate, or short lived, occurrences and can cause rapid growth. There are also other conditions which seem inversely related. In areas of poverty and lower living conditions, birth rates are sometimes higher. This can result in birth rates higher than those of industrialized nations where birth control is ubiquitous and pregnancy is put off for some time. Another cause of population growth is older populations living longer while birth rates do not decline. Many nations are experiencing rapid population growth of that sort in numbers that havent existed in the past. Any combination or single factor can cause the population number to increase in the immediate, but some factors are more likely to cause sustained growth. Effects oPopulation growth, even rapid population growth, can be a positive thing. Examples include corrections when the rapid growth may actually supply a population that wouldnt have existed to contribute otherwise. With sustained growth and rapid growth though there is a risk of overpopulation. When the level of overpopulation is reached, a number of negative effects can occur and a number of startling correlations are being discovered. Among the most definite and devastating effects of overpopulation is lack of land. The lack of land results in a number of things which result in negative impact on the population. Waste management of such populations is also difficult to handle effectively and can result in pollution and detriment to the environment. Without adequate land per individual the quality of housing decreases. Another result is insufficient land to produce crops. This results in hunger and ultimately starvation. These can be catastrophic and cause repercussions in the process. One example of these problems was London after the Industrial Revolution. Because of the population explosion in London, living space was minimal, leading to overcrowded conditions. A lack of food caused malnutrition, and poor waste management led to contaminated water supplies, which caused high levels of disease, such as typhoid and cholera. Changes in population sentiment oA newer correlation that has only recently been adequately studied to comment on is the effects on social stability of overpopulation. While it may seem evident that starvation may cause discontent, scientific studies have recently shown correlation between overpopulation and civil unrest. In many areas of unstable populations higher numbers of civil conflict within the area exist. Correlations like these often risk being self-sustaining and can spiral. Looking forward oNo single action is effective against all instances of rapid population or overpopulation. Some instances of rapid population growth may be a healthy response to some new factor. Monitoring populations and helping with the individual causes of unhealthy rapid population growth may help to prevent sustained overpopulation.
