Single nucleotide polymorphisms and recombination rate in humans :: Biology Genetic Diversity
Humans have many of the same genes but also a lot of genetic variation. Therefore, gene sequencing is different in everyone. This genetic variation determines a person's eye color, hair color, and other traits. However, this is also why some people get diseases and others don't. In a chromosome, the distance from the centromere dictates the rate of recombination. There is less shuffling in the area around the centromere, so that leads to less variation. However, understanding variation is necessary in order to determine abnormal genes. A single gene is the basis for identifying the abnormality. By looking at non-random sites with gene differentiations, one can determine the gene that causes the disease. There is more variation in regions with recombination, which happens in meiosis. The rate at which the crossing over occurs varies, and this affects the variation present. Shuffling is not the only determinant for variation in a gene. Selection also plays a role. For example, A gene is superior to B gene. C gene is connected to A gene through genetic hitchhiking. If A gene is selected over B gene, C gene is also expressed frequently. This is known as genetic hitchhiking. A biological application of this is the malaria gene. The colorblindness gene is hitchhiked onto the malaria resistant gene. Therefore, when a person receives the malaria resistant gene they also receive the colorblindness gene. As a result, colorblindness occurs more frequently in places where malaria is affluent because the people who don't receive the malaria resistant gene die and the people who are resistant and colorblind live and pass on their genes. Implications The main implication of this experiment is that comparing the differences in the various genotypes of humans can illustrate genetic diseases. For example if a subject has a certain genetic disease, this paper states that you could compare the afflicted subject's genome to an unaffiliated person's genome and determine the location of the disease on the chromosome. If the location of genetic diseases are found then it is conceivable to screen fetuses for genetic diseases. This brings up ethical issues, would you want to know if your child has an incurable genetic disease? If genetic diseases are detected in a fetus then it may be possible to someday perform gene therapy. Gene therapy is the treatment of a genetic disease by providing patients with cells containing harmless and functional alleles for genes that are nonfunctional in their bodies.

Sanitation and Housing Conditions Alexandria, Virginia Essay -- Urban
Alexandria is an independent city in the Commonwealth of Virginia and is recognized as one of the best places to live and do business on the east coast. The cityââ¬â¢s urban planning showcases the cityââ¬â¢s vibrant, diverse, historic, and unique neighborhoods. Urban planning began there in the 19th Century. Urban populations rose drastically, and a host of problems came with it: unsanitary conditions, overcrowding, and corruption of government. Economic depressions promoted a climate of social unrest, violence, labor strikes, and disease (Rose, 1997). In the beginning of the 19th century, development of American cities often took a compact, mixed-use form, reminiscent of that found in places like old town Alexandria. By the early 20th century, the focus was on the geography of water supplies, sewage disposal, and urban transportation (Virginia Places, 2010). This paper will discuss the cityââ¬â¢s historical and current sanitation program and housing accommodations for sewage disposal. Before the 19th Century, sewage disposal was virtually unknown until the first American cities were built around the 1700ââ¬â¢s. Human waste was originally disposed of in the woods, but some wealthy Virginians built large houses and used chamber pots to "do their business" indoors, and the contents would be thrown into the back yard. Later, as towns developed, waste was tossed into the streets to decompose or be washed away in the rainstorms (Virginia Places, 2010). Privies or outhouses were also built in back yards and were commonly used to dispose of waste. Toilets, also known as ââ¬Å"water closets,â⬠were put into homes in the mid 19th Century in the United States. The water closet had indoor plumbing where piping was run through the roof, and a gravity ... ...thier ecology ââ¬â making the city easier to sustain into the coming years.

Graduation Speech: The Best Four Years of My Life! :: Graduation Speech, Commencement Address
Hi, my name is Pat and I would like to start today by thanking the seniors of 2012 for choosing me to speak today. It is truly my honor. You know, it is really strange how quickly time passes, after spending my whole childhood wishing I was an adult, now here we are and it's a little hard to grasp. It feels like just yesterday I was standing here in the same position at eighth grade graduation. Ahh, middle school, such a joyous time for all of us, free of maturity and not a care in the world. The biggest decisions I ever had to make then was deciding which group to stand with at passing time and choosing which shirt from my extensive collection of Stussy and No Feat apparel to wear. We were all naive to the danger that lurked just around the corner. We were unaware that the carefree world we lived in was about to come crashing to the ground in a blazing inferno of real school work and responsibility ... otherwise known as high school. I am only kidding. It's just when you're young it is easy to get caught up in the here and now, and hard to look to the future. I thought high school would never end and now here we are on the brink of having to go out into the world and actually support ourselves!? I now feel like I never really appreciated my time here and never realized what a valuable experience it would be for me. I spent so much time complaining about high school, I never really had anytime left over to just enjoy myself. There are so many experiences from high school we will all carry with us through out our whole lives and will ultimately help determine what kind of person we are. By the time the end of my junior year rolled around I was ready to get away, so I enrolled in the Running Start program. I felt I had outgrown all that school activities had to offer and I wanted to just get on with my life. But as many teachers have clearly demonstrated over the last four years; you never get too old or too mature to have a little fun in high school. It took me this year to realize this. It was around homecoming that I started to feel a little left out.

Heroes and villains essay Essay
In todayââ¬â¢s society, one does not need to wear a cape or be able to fly to be a hero. Someone does not need to wear black and have an evil laugh to be a villain either. Today, an ordinary, everyday person can be transformed into a hero or villain almost instantly. A catalyst is definitely needed to perform this transformation. An event usually has to pull out the heroic traits of a person. For instance a person who witnesses a car accident and this person runs to the scene of the burning car and pulls the occupant(s) out risking his own life in doing so. If this accident had not had happened, this person would never have been considered a hero of any sort. Another example of this is Stuart Diver. He was buried in a landslide in 1997. After 3 days and against all odds, Stuart was pulled alive from the ruble. The media labeled him as a hero. One day Stuart was skiing in Threadbo, the next he was fighting for his like under his house and the next he was a household name and a hero. To become a villain there is a different ââ¬Ëprocedureââ¬â¢. A person must perform an evil act to be considered a villain. Suicide bombers are instantly classified as villains the second they detonate their bomb. 2 minutes before the detonation, the bomber was an ordinary person who looked like he was minding his own business, no one could have suspected he was a soon-to-be villain. But people must remember that these are martyrs for their cause. They feel they are doing the right thing by killing people and their people idolize and label them as heroes. Another example of this is ââ¬Ëchopperââ¬â¢ Reed. He went around the streets killing many people who he labeled ââ¬Ëbadââ¬â¢ people (mainly drug dealersâ⬠¦). Chopper thought he was doing the world a favour by killing these people, but as society states ââ¬â anyone who kills is a villain. A person who accidentally releases a poisonous gas and kills many people can also be labeled a villain by definition, but I believe a villain has to have the intention to create havoc and evil. So this is an example of how anà ordinary person can suddenly be called a villain by way of a mistake ââ¬â which acts as the catalyst. So yes, ordinary people can suddenly become villains or heroes at the flick of a switch but there is always going to be a catalyst, an event that will perform the transformation.

Diffusion Of Responsibility Theory
Responsibility theory is like human responsibility, social responsibility and is related to legal responsibility. It is an ethical theory that says, everyone has its responsibility and are accounted to the society whether an individual, a bigger one like a town, a company, or the government. It is of importance to basically magnify its simple principles. Social responsibility is the answer to the inquiries on why people are subjected and often times ending up in to blaming, admonishing, and punishing each other.It is simply voluntary; it is on the subject of giving more than, further than and beyond what is called for by the law or the ââ¬Å"legal responsibilityâ⬠. Wherein you a person is accounted and responsible not because there exist a law, a rule, or an order from a higher being in position. There exists a basis of volunteerism. Diffusion of Responsibility Theory If you have a neighborhood or someone who is in trouble or in a snag and a group of people are standing, watchi ng around, they usually tend to do nothing. This common scenario has been well studied.Distinctively, the idea of diffusion of responsibility is merely cycling in this. The theory here is that responsibility diffuses or disperses across and among the group such that no individual could feel enough and aware himself enough to step forward and get involved. Some analogous situations may also occur like in situations in committees, when a thing has been existing around them waiting to be accomplished yet ignored after sometime, students are subjected to the establishment of blame, admonishment and punishment.And in this case, responsibility theory has some noteworthy advantages. Social responsibility in a huge way is important for it is a principled, moral or ideological theory that a person whether it is an administration, a conglomerate, an organization or an individual has accountability to the society or the general public. This theory is voluntary: it is on the subject of giving m ore than, further than and beyond what is called for by the law. This ââ¬Å"called for by the lawâ⬠is simply the ââ¬Å"legal responsibilityâ⬠and this is somehow not in the boundaries of volunteerism principles.Wherein you a person is accounted and responsible not because there exist a law, a rule, or an order from a higher being in position. In here, a person canââ¬â¢t promise a free accountability for his people. It is out of his deep willingness to do a certain thing and only accounted and responsible when he is obliged by something: for example, it could be a law or a rule. To explain this topic further, let us have this simple basis example. By law, a conglomerateââ¬â¢s or a corporationââ¬â¢s main responsibility is to produce money (income) as much as possible for shareholders and make it a point that they obey the law.Social responsibility even with no contact onto the people involve, accompanies organizations being responsible for the people as well as f or the environment they affect. This organizations or companies have the ethics, moral responsibility to do so with regards to their power and influence. They certainly have this dominance or power to help people or, could be at the least, not harm them. This responsibility theory is a principle of law that connoting every being whether it is a small group like village, town, or the big ones like companies, government or could be just an individual has its own accountability to the society.In this responsibility theory, I couldnââ¬â¢t miss out mentioning these two universal rules because I believe it somehow relates each other and crosses each othersââ¬â¢ principle. First is, The Golden Rule: Do unto others what you want others do unto you. And second, The Utilitarian Principle: here is where you behave in a way that could result in for the benefit of the greatest number and for the greatest good. The connection among them is like this.Letââ¬â¢s say, some people emphasize t hat industries or companies have no responsibility (social responsibility) other than to augment their firms, enlarge returns, and abstain or desist from appealing in deception and fraud. It just means that the more they seek to maximize returns; they almost more often than not incidentally do what is good for the society. Building on the diffusion of the theory of responsibility and added subject matter- volunteerism, one way or another certainly it squabbles that a sense of responsibility originate transversely the personal and social domains of individuals who volunteer.

ââ¬ÅA Study on the Relationship between Overpopulation and Depletion of Natural Resources that Affects the Economic Status of the Philippinesââ¬Â Essay
In the year 1990, there were approximately 60.70 million people living in the Philippines. Population increased from 1990 to 2000 by approximately 15.81 million people. In 2012, the Philippines total reaches 103.78 million compared to the 2000 population of 81.16 million. The size of the human population is changing at an extremely high rate in the last years which makes the state the 12th most overpopulated country in the whole world. According to U.S. Agency for International Development (2000), it is foreseen that in the year 2030, the population growth will be unstoppable and will be doubled. Population matters in countryââ¬â¢s economy. The rapid population growth is revealed to have both affirmative and undesirable impact on economy and financial system of a country depending on how it is utilized. An overpopulated country is said to produce great number in terms of human resources. Villegas (2010) stated that large population is ââ¬Å"both a source of manpower and as a base for a domestic market on which the economic growth of a country can be sustained, despite periodic ups and downs in the global market.â⬠It also points positive impact on economies of scale and specialization, the possible spur to favorable motivation caused by increased dependency. However, overpopulation and rapid population growth hinders economic development. Theoretical analysis contends that high population growth creates pressures on limited natural resources. If population grows at 2% a year, supplies of housing, food and other goods must increase that much just to maintain the current standard of living. Water Resources Water is a basic economic resource which is a natural endowment to man. Nowadays, it is becoming a scarce resource with the ever-growing demand for household and industrial consumption. As an economic resource, pricing of water is largely determined by the cost of extraction from its natural water supply source and the cost of distribution. Water is likewise a basic need for the survival of individuals and family households. Many health and morbidity problems are associated with the quality and availability of water for human consumption. With the ever increasing population, the demand for potable water in urban areas has also increased, while the water sources began to decline over time. Water pollution is a major reason for the decreased availability of and access to clean potable water. This was the observation made by Philippine Institute for Development Studies (PIDS) Senior Research Fellow Dr. Danilo Israel whose review imputes poor management of freshwater water resources, particularly in the area of water pollution. He says that while freshwater is abundant in the country, estimates show that only 39 percent of classified inland surface water bodies are potential water sources for domestic use. Based on further estimates, he also said that only 1,907 cubic meters (the second lowest among Southeast Asian countries) of freshwater are available to every Filipino annually. This predicament, according to Israel, is further exacerbated by water pollution. Access to clean and adequate water remains an acute seasonal problem in urban and coastal areas in the Philippines. The National Capital Region (Metro Manila), Central Luzon, Southern Tagalog, and Central Visayas are the four urban critical regions in terms of water quality and quantity. If this trend continues, more Filipinos will not have enough access to safe-drinking water especially since demand for clean water constantly increases with population growth. As a consequence, the country may not attain the Millennium Development Goal that at least 86.6 percent of the population should have adequate access to potable water by 2015. Cleanfreshwater is a vital natural resource and without its ample supply, the lives and health of people could be put to risk. Specifically, there is a positive relationship between water pollution and water-borne diseases. The World Bank, for instance, has estimated that exposure to water pollution and poor sanitation accounts for one-sixth of reported disease cases, and nearly 6,000 premature deaths per year. Additionally, just over a third or 36 percent of the countryââ¬â¢s river systems are classified as sources of public water supply. Up to 58 percent of groundwater sampled is contaminated with coli form and needs treatment. Land Resources Land resources refer to a delineable area of the earthââ¬â¢s terrestrial surface, encompassing all attributes of the biosphere immediately above or below this surface, including those of the near-surface, climate, the soil and terrain forms, the surface hydrology (including shallow lakes, rivers, marshes and swamps), the near-surface sedimentary layers and associated groundwater and geohydrological reserve, the plant and animal populations, the human settlement pattern and physical results of past and present human activity (terracing, water storage or drainage structures, roads, buildings, etc.) (FAO/UNEP, 1997). Arable land (suitable for growing crops) covers just three percent of the worldââ¬â¢s surface. Based on historical data arable land decreases by 25 million acres annually ââ¬â it is estimated that one hectare (one hectare equals 2.47 acres) of productive land is lost every 7.67 seconds. The greatest causes of lost productive land are desertification and urbanization. New deserts are growing at a rate of 51,800 square kilometers per year. As the dwindling forest cover, logically increases rainfall runoff, which favors the floods, soil erosion and reduces the amount that seeps into the ground to recharge aquifers. Wetlands often disappear in bits and pieces as developers fill in small ponds or parts of swamps and deltas. The cumulative effect, however, can be devastating for wildlife and people. In some states, more than 90 percent of wetlands have vanished. Wetlands not only support wildlife but also filter the drinking supply humans rely on. Half of the planetââ¬â¢s plant and animal species live in rainforests. Less than 2.5 billion acres of tropical forest remain from the four billion acres on Earth just a few hundred years ago. That translates to a huge loss of habitat, and the likely extinction of untold species. Most of the deforestation has occurred in the last few decades. There are many causes of habitat destruction, including logging, mining, oil drilling, and exploiting other natural resources; clearing land for agriculture and cattle ranches; development for residential areas; and roads for people to do all these activities. If the present rate of destruction continues, todayââ¬â¢s forests will be gone by the year 2081. The total land area of the Philippines is about 30 million hectares, half of which is classified as forestlands, 47% as alienable and disposable lands, and the remaining 3% as unclassified forestlands. Logging has seriously depleted forest cover since the early 20th century. And there are more problems arising from the reduction of forest cover, as they will facilitate access to forest roads to pick up lumber, etc., They become drier and more susceptible to fires, which further reduces more wooded area and this, in turn, makes less rainwater to seep into the ground. Agricultural Resources As human population expands, the damaging effects on the environment multiply. Fast depletion of natural resources is just one of the effects of overpopulation. In our relentless effort to quench our never ending needs, we have destroyed the habitat of so many flora and fauna that this planet had nurtured to near perfection, through billions of years of evolution. The central issue for us over the next few decades is not climate change or the global financial crisis ââ¬â it is whether humanity can achieve and sustain the enormous harvest we need from this planet to feed ourselves. The earth is only capable of sustaining a certain amount of life. As the population continues to rise, the supply of food will continue to dwindle. We can only produce a fixed amount of food with the resources we have. The rising number of humans also necessitates further land for them to use as habitation. Therefore, the more land used for us to live on, the fewer land is available for farming. It is a vicious circle which has no end if the population growth is not curbed. The food consumed by human is influenced by wide range of cultural and individual differences, mainly due to ecological as well as personal reasons. The source of much of the food consumed by man is terrestrial agricultural, which represents the most manipulated of all the non-urban ecosystems. There are two main types of agriculture (1) Crop agriculture in which plant production is harvested for use by man and (2) Animal agricultural where a crop from highly manipulated ecosystem is fed to domesticated animals. Food consumption pattern is different in different regions. The most important feature is that rice to the staple food for most Asians. In general a strong and healthy human consumes about 1.4 kg of food every day. Such a food serves as a source of energy and replacement of uses. Statement of the Problem The study focused on the relationship between overpopulation and depletion of natural resources that affects the economic status of the Philippines. Specifically, the study sought to answer the following questions: 1. How does overpopulation affects our natural resources such as: a. Water b. Land; and c. Agriculture 2. How the environmental impacts due to overpopulation do affects the economy of the Philippines? Objectives of the Study The study intended to investigate and to improve the understanding on the relationship between overpopulation and depletion of natural resources that affects the economic status of the Philippines. More specifically, the objectives are: 1. To evaluate the effects of overpopulation on natural resources such as water, land and agriculture. 2. To determine the effects of depletion of natural resources due to overpopulation on economy of the Philippines. Significance of the Study The basic definition of economics is choice under scarcity. Economists like to study how scarcity of resources and the differences in the distribution of these resources affect decisions made by the people. This concept can be applied and is significant to a single person, a family or a country. Natural resources are not only in the Philippines, but also in the whole wide world are limited and scarce. Water, for example, a lot of people need it but there is a limited amount of it, and so they see a market develop for it. In addition there are things like land and labor. If people could all have whatever they wanted, there would be no need to ration or trade, and therefore, there will be no Economics. Another, the management of natural resources is one of the most critical challenges facing the developing countries of today. The exploitation of high-value natural resources, including oil, gas, minerals and timber has often been cited as a key factor in triggering, escalating or sustaining violent conflicts around the globe. Furthermore, increasing competition and conflict for diminishing renewable resources, such as land and water, is on the rise. This is being further aggravated by environmental degradation, population growth and climate change. The mismanagement of natural resources is contributing to new conflicts and obstructing the peaceful resolution of existing ones. This study is substantial to all the sectors of the economy, may it be the government, the private firms or the commoners and the residents of every country. This will give them the proper knowledge about how population affects the limited natural resources. Aside from being an informed citizen, this study aims and is significant to make a difference. This research is a qualitative research and not an action. There will be no particular question to be asked and no certain acts to do. But due to this paper, the readers will think and give ideas within themselves on how to preserve the natural resources and not ruining it. This is important to give standing to the issues concerning different aspects of the economy. Definition of Terms Economics ââ¬â A social science that studies how individuals, governments, firms and nations make choices on allocating scarce resources to satisfy their unlimited wants Macroeconomics ââ¬â concentrates on the behavior of the aggregate economy Microeconomics ââ¬â focuses on individual consumers. Overpopulation ââ¬â is a term that refers to a condition by which the population density enlarges to a limit that provokes the environmental deterioration, a remarkable decline in the quality of life, or a population collapse. Population density ââ¬â denotes the number of inhabitants dwelling in a specific area, for example: 100 inhabitants per square Kilometer. Natural resources ââ¬â is resources occurring in nature that can be used to create wealth. Gross Domestic Product (GDP) ââ¬â is the total market value of all final goods and services produced in a country in a given year, equal to total consumer, investment and government spending, plus the value of exports, minus the value of imports. Gross National Product (GNP) ââ¬â is the total value of all final goods and services produced within a nation in a particular year, plus income earned by its citizens (including income of those located abroad), minus income of non-residents located in that country. Desertification ââ¬â is the conversion of grassland or an already arid land into a desert through indiscriminate human actions magnified by droughts. Resources depletion ââ¬â an economic term referring to the exhaustion of raw materials within a region Chapter II THEORETICAL FRAMEWORK This chapter provides a framework for understanding the relationship between overpopulation and the natural resources. Figure 1.1 The Variable and its Relationship Economics deals with the efficient allocation of limited resources to satisfy the unlimited consumption of the citizens. Governments intervene on balancing scarce resources through mechanisms such us price rationing system. They can facilitate economic activity in certain geographic regions. There is a direct relationship between population and resources. Figure 1.1 shows different variables in the study, population as the independent and natural resources such as land, agriculture and water as dependent variable. This study will provide sufficient knowledge on the effects of great population in the Philippines to the limited and scarce resources that the country is facing. Moreover, it will suggest some solutions on how it will be efficiently allocated to the citizens of the country. Philippines, as one of the developing countries, contributes on the worldly economic activities, thus, making its own economy create a great impact on the economy of the world. Chapter III RELATED STUDIES The Philippines is bounded on the east by the Philippine Sea, on the south by the Sulu and Celebes seas, on the west by the South China Sea, and on the north by Luzon Strait. The Philippine Islands lie off the southeastern coast of the Asian mainland, across the South China Sea from Vietnam and China. The shortest distance to the mainland, from the northern Philippines to Hong Kong, is about 805 km (500 mi). The Philippine Islands extend about 1,850 km (1,150 mi) from north to south (between Taiwan and Borneo Island) and about 1,100 km (700 mi) from east to west. Malaysia and Indonesia, which each hold territory on Borneo, are the republicââ¬â¢s closest political neighbors. The Philippines covers a total area, not including its extensive coastal waters, of 300,000 sq km (116,000 sq mi). More than 7,100 islands and islets are included in the Philippine archipelago. The 11 largest islands make up more than 90 percent of the total area. Only about 460 islands are larger than 2.6 sq km (1 sq mi), and about 1,000 are populated. The Philippines has extensive mineral deposits of copper, gold, silver, nickel, lead, and chromium. Other important, but less plentiful, deposits of zinc, cobalt, and manganese also exist. Copper has been mined extensively and is the leading mineral product, but many of the countryââ¬â¢s mineral resources remain unexploited. The Philippines has limited offshore petroleum and natural gas reserves. About 19 percent of the Philippines is forested. Logging has seriously depleted forest cover since the early 20th century. The Philippine waters are abundant with many varieties of fish, which are an important natural resource as a staple of the Philippine diet and an export commodity. Johnson (2012) stated that one thing all humans on this planet need to survive is resources. Resources like food and water are bare essentials for life. The countries that are experiencing the highest growth rates are all developing countries, with the exception of the United States. This countries lack the technology that other developed countries have and therefore things we consider basic they have never used. We watch our televisions everyday while they may have never seen a TV before. They also lack the basics that we take for granted like indoor plumbing. Some countries water supply is the same as their sewage. India has one of the fastest growing populations in the world and the Ganges River shows their lack of resources available to the people of India. The Ganges is one of the most polluted rivers in the world. It supports over 400 million people with a population density of 1,000 people per square mile. India is an example of developing country that has a rise in its population growth rate. It cannot support its population now; many of the people in India are forced to bathe in the Ganges because they have no access to any other water source. If this population continues to grow the river will continue to get more and more polluted making it unsafe for the millions of people that rely on it. This is not the only place in the world that the larger populations are supported by limited resources. Along with the people in India relying on the Ganges over three fifths of people in developing countries lack basic sanitation, one third have no access to clean water, and a quarter lack adequate housing. More often than not the places where the population growth rates are the highest are the places least able to support the rise in population. Only the United States can continue to support one of the worldââ¬â¢s largest populations because we are a developed country and the increase comes mostly from immigration. These countries that continue to grow, despite being limited in resources, are the biggest areas of deforestation and depletion of natural resources. These areas lack strong government and are unable to enforce the depletion of resources. The United Nations predict that currently 1 billion people lack the basic needs that we take for granted every day. With a lack of technology developing countries will continue to destroy resources at an alarming rate while many struggle to survive every day. Freshwater is the most fundamental of finite resources. It has no substitutes for most uses and is expensive to transport. But freshwater sources are dwindling or becoming contaminated throughout the world. Chronic or acute water shortage is increasingly common in many countries with fast-growing populations, becoming a potential source of conflict. However, existing technologies offer great potential for improving on the efficiency of its use. Based from the study of Walden Bello, the state of the economy, even some of the administrationââ¬â¢s friends have pointed out, is a thin reed on which to rest. In a recent article, Peter Wallace, an influential consultant, deconstructed the 7.3 per cent growth rate recorded for the Philippines in 2007, showing that the figure is actually a statistical fluke that stems from the way the measure Gross Domestic Product (GDP) is computed. The figure actually masks something negative: the fall of imports by 5.4 per cent. ââ¬Å"So because we had less imports, GDP looked good,â⬠Wallace says. ââ¬Å"From where I sit, that does not indicate a strong, growing economy, the best in 31 years.â⬠With no less irony, the World Bank agrees: ââ¬Å"Remarkably, weaker import growth made the largest 1arithmetical contribution to the growth acceleration in 2000-07 compared to 1990-99.â⬠It added that this was not ââ¬Å"consistent with sustained fast growth in the longer term.â⬠The reality, Wallace points out, is indicated by the same brutal numbers: more poor people in 2007 than in 2000, more people without jobs, a real decline in average family income, the shrinking of the middle class as more people jump ship and swim to other shores. ââ¬Å"Notwithstanding higher growth,â⬠the World Bank chimes in, ââ¬Å"the latest official poverty estimates show that between 2003 and 2006, when GDP growth averaged 5.4 per cent, poverty incidence increased from 30.0 to 32.9 per cent. This level of poverty incidence is almost as high as it was in 2000 (33 per cent). Indeed the magnitude of poor Filipinos rose to its highest level in 2006: of a population of 84 million in 2006, 27.6 million Filipinos fell below the national poverty threshold of P15, 057.â⬠If you pop the famous ââ¬Å"Ronald Reaganâ⬠question to most Filipinosââ¬âââ¬Å"Do you feel better off now than four years agoâ⬠ââ¬âthere is no doubt about how they would answer. For many people, the main problem confronting the economy is spelled G-MA. But for those who have spent time studying the Philippine economy, Arroyo is not the problem, but part of a bigger problem that extends far into the recent past. The collective responsibility of the last five administrations for our economic malfunctioning becomes stark when viewed in a comparative context. According to the latest Human Development Report of the United Nations Development Program (UNDP), with the growth in GDP per capita averaging 1.6 per cent per annum in the period 1990 to 2005, the Philippinesââ¬â¢ economic growth record was the worst in Southeast Asia, with even all the so-called lower-tier ASEAN countries significantly to outstripping it. Chapter IV RESULTS AND DISCUSSION The worldââ¬â¢s population reached over 6.60 billion in July 2007 and will reach 6.68 billion by July this year and 7.00 billion by July 2012 (according to CIA estimates). Countries with large populations and few food resources or poor food distribution programs could end up becoming desperate refugees moving to their neighboring countries. One out of every seven people alive, go to bed hungry. Every day, 25,000 people die because of malnutrition and hunger-related diseases. Almost 18,000 of them are children under 5 years old. Figure 4.1 Population in the Philippines The figure above shows the increasing population of the Philippines. From approximately 80 million, the population increases up to 100 million. As population increases, natural resources also get used up faster than they can be replaced. This can result on economic pressure and interrelated web of global environmental problems such as resources depletion. Problem no. 1 How does overpopulation affects our natural resources such as water, land and agriculture. Population and Water Resources Population influences the freshwater resources, its quality and supply, in both rural and urban areas through demands for water and human activities such as irrigation. One major consequence of overpopulation has been the outstanding usage of freshwater, thus leading to a major freshwater crisis that will definitely affect the future of our planet. It is also domineering to see the whole issue in perspective and how the increasing number of people in the surface of the Earth is relative to the amount of waste being produced. Hence, the constant pollution of the environment, along with bodies of water has exponentially decreased the quantity of usable water for the future of our generations. This has critically been an issue because the oceans are mistaken for available water, but in actuality, the Earth has a finite supply of fresh water which in order to be converted from saline water to potable water, the amount of energy needed is prohibited. Thus water has become quite a scare commodity that few countries and civilizations seem to take into consideration. The National Water Resources Board under the Department of Environment and Natural Resources in Philippines is responsible for ensuring the optimum exploitation, utilization, development, conservation and protection of the countryââ¬â¢s water resource, consistent with the principles of Integrated Water Resource Management. The country is endowed with rich natural resources ââ¬â including water ââ¬â which are essential for the countryââ¬â¢s economic development and in meeting its Millennium Development Goals (MDGs). Water resources of the Philippines include inland freshwater (rivers, lakes, and groundwater), and marine (bay, coastal, and oceanic waters). Overall, there is sufficient water but not enough in highly populated areas, especially during dry season. Citing the Environmental Management Bureau (EMB), Israel explains that the number of monitored freshwater bodies which failed the standard in terms of Dissolved Oxygen (DO) and Biological Oxygen Demand (BOD) has been increasing significantly at average annual rates of 22.90 percent and 22.30 percent, respectively, from 2000 to 2007. Likewise, he explains that many freshwater bodies, especially those in urban areas, have been contaminated with suspended solids, heavy metals and other harmful chemicals. Population and Land Resources According to Higgins (1982), carrying capacity presumes that there are critical levels of population that any given land area can support. This level is determined by soil and climatic conditions. The carrying capacity and population has a direct relationship. When population increases in a given area, the increased demand on production can induce stress and consequent degradation of the land resource. As population grows continuously, the space in a given place remains constant, thus, making it limited. Land resources can also be limited because of land problems and imbalance. In the past 100 years the world has lost almost half its forest area. And, as indicated by reports of the FAO (Food and Agriculture) the Earth is losing on net every year 11.2 million hectares of virgin forest. This is reportedly the World Wildlife Fund, mainly due to its use as an energy source (about 2000 million people worldwide depend on wood as fuel) of agricultural and livestock expansion and mining and logging companies activities, often beyond control. Population and Agriculture Some theories propose that population growth would outrun the ability to produce food, thus, leading this to famine, disease, and other disasters. The use of land, specifically in agriculture, is an essential part of humanity. We depend on agriculture to supply us with food, fiber and biofuels. Without a highly efficient, progressive, and productive agricultural system, our society would collapse and cease to function. As the population grows and grows continuously, we are demanding more and more from the agricultural systems, pushing them to their limits. At this rate, we would have to double, or triple the agricultural production in our economy. The rapid increase in population, urbanization, and industrialization has also adversely affected the quality of water, especially in densely populated areas and regions of industrial and agricultural activities. The discharge of domestic and industrial wastewater and agricultural runoff has caused extensive pollution of the receiving water-bodies. Problem no. 2 How the environmental impacts due to overpopulation do affects the economy of the Philippines? As the population grows, it pushes the GDP per capita of a nation down. While the government tries to meet the needs of its people, with increase in population, the demand for resources keeps growing. With not enough food to take care of its men, such countries canââ¬â¢t even think of producing surplus to export and with this starts the vicious cycle of relying on foreign debt. With more people and less resources, there is unemployment that leads to poverty and increased crime rate. Shrinking habitat is giving rise to increased conflict between man and animals. As the borders between forests and human settlements gets blurred by the day, human beings are being exposed to viruses that are carried by wild animals who have the immunity that we lack. This is precipitating in newer and more virulent strains of microorganisms causing serious diseases in human beings. CONCLUSION AND RECOMMENDATION The human population has been increasing at an extremely high rate in the last century and unfortunately, not much has been done to slow down this process. Undoubtedly, overpopulation is a global issue. It is global because it pertains to all of humanity, but global also means that it affects the whole world, i.e. the environment. Almost all human activities impact negatively the environment in one form or another, and as human population expands, the damaging effects on the environment multiply. As the population grows, it pushes the GDP per capita of a nation down. While the government tries to meet the needs of its people, with increase in population, the demand for resources keeps growing. With not enough food to take care of its men, such countries canââ¬â¢t even think of producing surplus to export and with this starts the vicious cycle of relying on foreign debt. This puts the country in debt at stretches the governmentââ¬â¢s already meager resources. Furthermore, when a country is overpopulated, there is a high rate of unemployment because there just arenââ¬â¢t enough jobs to support the population. This results in a high level of crime because the people will need to steal things in order to survive. As natural resources become scarce, the production is bound to decrease. However, in a crowded society, demand remains strong. This causes the prices of goods increase, in order to balance supply and demand. However, a price change cannot suddenly reduce the need for a large population of. Therefore, prices remain high and continue to grow even as people consume expensive products. The depletion of natural resources is one of the most critical problems of the global community is facing, especially after the sharp increase in world population over the last century. Each person has a number of vital (food, drink, clothing) and non-life (education, employment, recreation) needs, which all require the consumption of Earthââ¬â¢s resources. When the number of people applying to these needs becomes extremely high, the shortage becomes a critical problem in extreme cases can cause a ââ¬Å"Malthusian catastropheâ⬠According to the theory of overpopulation advanced by Enlightenment demographer Thomas Robert Malthus, Malthusian catastrophe is an event which results from a period of unchecked population growth. Many determining factors build the success or demise of a country. Our forefathers have created that successful nation with blood and sweat, through trials and tribulations. It is up to this generation to ensure the advantageous outlook of this country for our future offspring. This population difficulty casts an impending downfall for our country and must be stopped. Research and analysis need to be performed, consequently summarizing the most favorable actions to be taken. These actions then need to be embraced by state and federal governments, who in turn need to be aggressive in enacting firm and dynamic policies to thwart this crisis. Food shortage will be prevented or lessened if we quickly stabilize population and find some as-yet-discovered agricultural advancement. Overpopulation causes rural farming people to outgrow their lands, so the grown children move to cities. Urbanization eats up farmland, reducing crop production. Also growing seasons are becoming hotter, so many crops fail due to heat and drought. Overuse of the soils caused by overpopulation leads poor nourishment for crops and eventually desertification. Overpopulation draws on available water to the point that there is not enough to water crops. REFERENCES Herrin, A. Population and Development Research in the Philippines: A Survey.

Drug Testing in a High School Setting: Pros and Cons
Taking steroids to enhance athletic performance has become widespread among athletes worldwide. This practice not only violates athletic regulations and the intent of fair competition but also damages many of the body's major organs. Drug testing has therefore been implemented in many collegiate and professional sports and some high school athletic programs with the goal of maintaining competitive fairness. Drug testing is the method that has been chosen to identify those athletes who use banned drugs to enhance their sports performance at the expense of the athletes who do not take drugs.Almost any athlete competing above the high school level, and increasingly at even high school level too, is subject to drug testing. There are almost as many drugs used by athletes as there are sports. Some athletic performance enhancers are not drugs at all. Some performance-enhancing techniques use human hormones (or synthetic derivates thereof), and other use the athlete's own blood. Some of the se techniques are presently undetectable by urine and blood samples. Drug testing alone will not be enough to stop the use of steroids and other drugs.While drug testing is the first line of defense at the collegiate and professional levels of sport, athletes, parents, and we coaches and trainers must bear the greater responsibility for keeping the playing field level at the junior high and high school levels. The use or possession of alcohol and illegal or controlled substances by students is reaching epidemic proportions. Along with traditional education and drug-resistance programs in the schools and the community, proactive prevention and deterrence measures must be in place and publicized to all students.Drug testing is part of a much wider picture. Curbing drug use and implementing drug testing policies are significant concerns of parents, administrators and us coaches. The important pros of mandatory drug testing within a high school sports setting are:Greater deterrence to d rug use.Promoting fairness in sports competitions.Helping drug users relinquish their drug dependency (punitive aspects need to be minimized)2. A brief history of drug testing Drug testing of humans began in the late 1950s, when, after several European cycling and track races, evidence of drug use was observed.In 1965, procedures were developed which were capable of detecting a number of different stimulants; these were used to test participants of the Tour of Britain Cycle Races. The fist formal testing for nonsteroidal drugs occurred at the 1972 Munich Olympic Games though there still was no official testing for steroids. The development of complex radioimmunoassay (RIA) screening procedures as well as analytical advances in gas chromatography-mass spectrometry (GC-MS) techniques led to the introduction of tests for anabolic steroids at the 1976 Montreal Olympic Games (Yesalis, Cowart 75).The test method of determining whether or not the testosterone in an athlete's body came from illegal use by the athlete was developed by Donike et al. in 1983. In 1992 Barcelona Olympic Games, the IOC laboratory reported the detection of several banned drugs in the participating athletes. High resolution mass spectrometry (HRMS) analysis was introduced in the 1996 Atlanta Sumer Olympic Games. In recent years, Liquid chromatography-mass spectrometry (LCMS) is being used in drug testing laboratories because it has several advantages over traditional GCMS technique.In the future, LCMS will become increasingly more important in the drug-testing laboratories because of its ability to confirm the presence of most drugs, including natural hormones (HGH, EPO, etc. ). Isotope Ratio Mass Spectrometry (IRMS) is a relatively new technique that is being proposed for verification of testosterone positives. Three decades have passed since sports drug testing became part of the Olympic Games. Drug testing is now part of professional sports, collegiate sports, and to a smaller extent, high school sports.The technology of drug testing has made significant advances; at the same time, cheating methods have also evolved and grown more sophisticated.3. The efficacy of drug testing in high schools Surveillance for drug use employing a random drug-testing model is currently receiving significant attention and consideration by high school administrators and public officials. In fact, random drug testing has been implemented in a number of school districts for students engaged in extra-curricular activities and is being considered for use with general student bodies.It is understandable that use of drug testing is being considered as a prevention tool with student-athletes since both NCAA and many professional sports employ this methodology. Further, many if not all NCAA Division 1 university athletic programs employ random drug testing at some level in response to concerns about drug use among collegiate athletes and because of potential NCAA sanctions for drug test failures . Hence, high school athletic programs are typically viewed as an aid to deter and to detect use. The efficacy of this tool in curbing drug use has yet to be thoroughly evaluated, however.Results to date have been rather equivocal with assessments both providing modest support for efficacy and indicating no effects. Funded by the National Institute on Drug Abuse, National Institutes of Health, the SATURN (Student Athlete Testing Using Random Notification ) project was designed to evaluate whether a nonpunitive, compulsory, random, suspicionless drug testing policy deterred drug and alcohol use among high school student athletes in two Oregon schools. Participation was required for all students and was a mandatory prerequisite for athletic participation.Results showed that a policy of random drug testing surveillance significantly reduced self-reports of recent performance-enhancing substances and, to a lesser extent, common drugs of abuse but did not produce long-term changes in sub stance use and associated high-risk behaviors use among adolescent athletes. Further, neither tobacco or alcohol use was altered. This result suggests at least limited efficacy when targeting a specific drugs that may be associated with well-documented harm potential to student-athletes.The authors of the investigation caution against over-interpretation of results suggesting efficacy of testing as adequate intervention (OHSU).4. Privacy ââ¬â the fundamental issue At the heart of drug-testing controversy in schools, however, is not efficacy but privacy. Public schools are state actors; thus, the constitutional protections apply with respect to students and employees of public schools systems. As public institutions, public schools must follow the dictates of the Fourth Amendment to the U. S. Constitution as well as any particular provisions form the state constitutions that apply to them.In essence, the Fourth Amendment protects people and their houses, papers and effects agains t unreasonable searches and seizures. Such protection is vital to the privacy protection of all citizens from unacceptable conduct on the part of the government or its officers or agents. If a search is conducted, and a drug test is considered a search, the search must be reasonable and the intrusion of the test on an individual's privacy must be weighed against the government's interest in conducting the test. Reasonableness will depend on the circumstances.However, in most cases, suspicion is not required in order to perform a test. Because the use of certain performance-enhancing drugs is illegal according to federal statutes, many institutions have attempted to implement drug testing policies in order to deter their students from using drugs and also to detect drug use. Such a measure is deemed necessary in order to either provide assistance to those who do no understand the dangers involved in drug use or to provide information to law enforcement official in order that they may become involved to rid the institution of drug users.At the high school sport level, officials realize that drug use can be particularly dangerous to the more susceptible bodies of growing children. However, many times the athletes forced to submit to a drug-testing program do not do so willingly.They feel that the drug test infringes on their privacy rights as protected by the federal constitution and that they should not have to submit to the test. These individuals are typically not drug users; instead they are participants who find that if they do not submit to the testing, they will not be able to continue participating in the sport or activity of their choice.Beginning in the 1980's, these individuals sued the institutions who developed the drug testing policies so that they could avoid being tested as a requirement of participation. Until 1995, institutions who attempted to implement drug-testing policies were often unsure as to whether their policies would be upheld in cour t of law. However, 1995 the U. S. Supreme Court finally dealt with the issue. In the Vernonia School District 47J v. Acton case, the Supreme Court reviewed the constitutionality of a drug testing program applied to student-athletes at the high school level.In the mid 1980s, teachers and administrators in the Vernonia School District, Oregon, noticed a sharp increase in student drug us and an increase in disciplinary problems at the school. The school district also found that student-athletes were both users and leaders of the drug culture (Imber, Geel 159). The district implemented a drug testing policy that applied to all students participating in athletics, requiring each student to sign a form consenting to the random urinalysis testing policy before being allowed to participate in sports.During the test, the student would enter a locker room with an adult monitor who would check the sample produced for temperature and tampering. In 1991, Seventh grader James Acton refused to sig n the consent form and was not allowed to play football. His family sued claiming that the drug testing policy violated the Fourth Amendment. After a long process of examining the case, the court finally ruled that students who are in athletics and other highly visible extracurricular activities have a diminished expectation of privacy.Schools may carry out certain suspicionless searches, such as random drug tests of athletes, the court ruled, because such tests are mandatory only for those who choose to participate in those voluntary activities.While general drug testing can been seen as unreasonable, specific drug testing has to be allowed ââ¬â especially, when it is limited to extracurricular athletics. The Vernonia School offered considerable discretion to school officials in their effort to control student behavior. According to the court ruling, individualized suspicion was not necessary before submitting students to random urinalysis drug testing.The court ruled that scho ol officials exercised their duties as state actors, an authority that was ââ¬Å"custodial and tutelary, permitting a degree of supervision and control that could not be exercised over free adults. â⬠The Supreme Court Justice Antonin Scalie, who wrote the opinion, also said that athletes have less of an expectation of privacy because they change clothes and shower together. The Court also said that since athletes can be role models, it is especially important to be sure that they do not use drugs.The reasoning in Vernonia has been extended to include all other extracurricular activities. Since 1995, numerous other court decisions have ruled in favor of school districts that conduct the random drug testing of student athletes, although the testing of other students is still conditioned on ââ¬Å"reasonable suspicionâ⬠by school administrators.Many developments since 1995 indicate the growing extensiveness of drug testing within the schools of the United States. For instan ce, in 1995 the Dayton County, Ohio, school district implemented a program to conduct random drug testing on student athletes.In September, 1999, the 6th U. S Circuit Court of Appeals affirmed the legality of Knox County, Tennessee, program designed to test teachers, principals, and other school employees. Harlan county, Kentucky, during the 1999-2000 school year, initiated a random drug-testing program for all teachers, principals, and administrators. From time to time, the various attempts of school authorities at implementing drug testing programs are seen as violating students' privacy rights when they require students to submit to blood or urine tests.An Arkansas Court, for example, ruled that there were less obtrusive (and intrusive) ways to determine rule infraction. In another development, a New Jersey school policy was rebuffed. The school board required students to have annual exams that included a urinalysis. If a student tested positive for drugs, then district officials notified the student's parents, hoping that the parents would then get treatment for the student. The court ruled this procedure as unreasonable.And although various school districts across the country are now testing employees and student athletes, a private high school in Memphis, Tennessee, has initiated random drug testing on its entire student body, a program endorsed and financially supported (to the tune of sixty dollars per test) by parents. Students refusing to submit to testing are to be expelled from school. Thus, drug testing on the entire student body may often raise several complicated issues. However, within the context of high school sports competitions, drug testing is very essential to ensure fairness.There are few cons to drug testing in high school sports, as long as such programs are executed in right spirit. The concern for fairness easily overrides the concern for privacy in a sports setting, as the landmark Vernonia case rightly concluded.5. Deterrence, not punishment Several other court cases in the subsequent years brought out the need for and the advantages of drug testing in high schools. In 1998, the Federal Seventh Circuit Court of Appeals upheld an Indiana school's random drug-testing of high school athletes and cheerleaders.In this case, the Court found the school's policy was reasonable under the Fourth Amendment. The school did not require observed specimen collection, a positive test did not result in expulsion, and privacy concerns of students that were required to disclose any medication they were taking were adequately addressed by the school. Additionally, students were give the opportunity to challenge positive test results by taking a conforming test at no expense to the student. Deterrence, safety and the health of students performing in athletic events constituted the basis supporting the courtââ¬â¢s judgment.The Court reasoned that the school system has responsibilities as guardian and tutor of children entrusted in its care and that deterring drug use by students is a compelling interest. The Court also noted that the school's program was designed to deter drug use, not to punish users. As coaches working in school setting, we must always strive to remember to lay stress on deterrence and not on punishment, only then the pros of drug testing can be maximized and cons minimized.The aim of drug testing is not to trap and punish students who use drugs. It is, in fact, counterproductive simply to punish them without trying to alter their behavior. If drug-using students are suspended or expelled without any attempt to change their ways, the community will be faced with drug-using dropouts, an even bigger problem in the long run. The purpose of testing, then, is to prevent drug dependence and to help drug-dependent students become drug free. (Office of National Drug Control Policy 22)
