What Policies Can Be Implemented to Reduce Human Population Growth? Essay Example Paper What Policies Can Be Implemented to Reduce Human Population Growth Essay Introduction The global rate of human population growth peaked during 1963. The number of people living on Earth, who are currently sharing limited resources, such as water and food, has amplified by more than two-thirds since 1963! Astonishingly, the world population is a bit over 6. 6 billion today. Human population is anticipated to exceed 9 billion by 2050. A majority of Environmentalists agree that most, if not all environmental problems will arise, such as climate change, species extinction, and overzealous resource extraction. According to Population Connection, the increase of human population since the 1950’s resulted to the clearing of 80% of rain forests, the loss of thousands of plant and wildlife species, a rise in greenhouse gas emissions, and the commercialization of half of the Earth’s surface land. Environmentalist distress that in during the approaching decades half of the world’s population will be exposed to water-scarce conditions, which are expected to d eepen the difficulties of meeting the consumption levels, and cause devastating effects on our delicately balanced ecosystems. To allow the people of the world to enjoy a decent living without draining natural resources and causing severe climate change, demographic trends must be reversed and a balance must be achieved between population and resources. A number of countries are already aware that their population growth rate is too high and some, (such as China) have taken actions to decrease birthrates, which is the best way to check population growth and relieve pressure on the planet’s environment. Most developed countries objective is to reduce the world’s population down to 4 Billion during or hopefully earlier 2100. What Policies Can Be Implemented to Reduce Human Population Growth? Essay Body Paragraphs This objective can be reached by establishing a Restricted Family Policy, meaning a maximum of 2 children per-family in all countries with high population densities. This would lead to a fertility rate of less than 2. 1, the level required for population replacement. It would be a good idea to take advantage of China’s experience over the past 30 years, despite the bad press China’s single child policy has gained, it has resulted in the avoidance of around 400 million births and the fertility rate has fallen from 5. 4 in 1971 to 1. 8 during 2005. The goal of the Restricted Family Policy is to reduce the fertility rate as rapidly as possible to 1. 5 in all countries that have over 10 million inhabitants. Why did scientists set the target rate at 1. 5? Simply, because it is urgent that we decrease the number of consumers so the world total population doesn’t reach 9 billion by 2050. If we want to dodge resource depletion and intolerable environmental deterioration the Restricted Family Policy must be carried threw efficiently. According to the Intergovernmental Panel on Climate Change (IPCC), â€Å"World greenhouse gas emissions attributable to human activities have grown since the preindustrial era. Between 1970 and 2004, the increase was 70%. † Most importantly during this process developed countries have an obligation to help decrease human population since they are the largest consumers and polluters in the world. As one may see below, policies in a number of developed countries to encourage large families must be abolished and increased immigration quotas encouraged, as they do not lead to an increased world population. 2006) Fertility rates and total population Country or Region Total Population (million) Fertility Rate China 1,313 1. 73 India 1,134 2. 81 Africa 922 4. 67 South America Caribbean 558 2. 7 United States 300 2. 05 Indonesia 226 2. 18 Pakistan 158 3. 52 Bangladesh 153 2. 83 Egypt 73 2. 9 France 61 1. 89 United Kingd om 60 1. 82 Therefore, one can see that much remains to be done to decrease the fertility rate to 1. 5. Once the balance between population and resources has been reached, the fertility rate can be allowed to increase to 2. 1 to ensure population replacement, this is why the Restricted Family Policy (which is known worldwide) is very important. The United Stated has also taken action by increasing education, especially considering environmental issues (since studies have shown that affluent families have fewer babies), strong availability of birth control, less restriction on abortion, charging for kids medical care, and hopefully during the near future limiting the number of births per-family. The already difficult task of reducing poverty and bringing about sustainable development in the developing world will, be made even harder, because of the predicted addition of several billions of people by the middle of the next century. Efforts to slow this population expansion have to foc us on reducing fertility. There are action and policies of reducing unwanted fertility and the unmet need for contraception by enforcing family planning programs. Roughly one in four births in the developing world (disregarding China) are unwanted, meaning a larger proportion of births are unexpected, this is mostly because of lack of education, and this is why family planning programs are necessary. In addition, an anticipated 25 million abortions are presented each year in less developed countries. One may ask, â€Å"Why do individuals fail to practice contraception? † The answer is a result of a mixture of social and health service related reasons. Such as lack of access to services or information was and remains a key obstacle. In addition, other factors such as fear of side effects of contraceptive methods and overt or suspected disapproval of husbands and other family members—are significant barriers to use in many societies. To be effective, programs must theref ore go beyond the simple establishment of services, and address social and health concerns as well. In the 20th century, population control proponents have drawn from the insights of Thomas Malthus, a British clergyman and economist who published An Essay on the Principle of Population in 1798. Malthus argued outlined the idea of positive checks and preventative checks are factors that Malthus considered to increase the death rate, and decrease birthrates. His theories is what created many policies. Preventative checks† were factors that Malthus believed to affect the birth rate such as moral restraint, abstinence and birth control, in many countries it has become a policy for the government to provide birth control pills, and educated teens on the consequences of pregnancy in order to lower birth rates (for example, in the United States many teens between the ages of 14 and 18 get pregnant). He predicted that â€Å"positive checks† save humanity from itself. Malthus we nt on to explain why he believed that this misery affected the poor in a disproportionate manner. Finally, Malthus supported the right for lower class people to be educated in order for them to be aware of how they impact the environment and the importance of moral limitations; this resulted to another policy, where every human being has the right to be educated, and government schools were established where lectures about the dangers of human population increasing, and pregnancy were given. Finally, Eco-scientists discuss many policies that can implement and reduce human population growth. Legalizing â€Å"compulsory abortions,† and forced abortions to be carried out against the will women who have already given birth to 1 or 2 children, this is very common in China. Babies who are born out of wedlock or to teenage mothers to be forcibly taken away from their mother by the government and put up for adoption, its believed that this will result to mothers demonstrating to the government that they can take care of a child, scientists believe this will result to a policy, where one must have a licensing to take care of a child. Implementing a system of â€Å"involuntary birth control,† where both men and women would be mandated to have an infertility device implanted into their body at puberty and only have it removed temporarily if they received permission from the government to have a baby. Permanently sterilizing people who the authorities deem have already had too many children. Supposedly, in the future all these policies would be overseen by a transnational and centralized â€Å"planetary regime† that would utilize a â€Å"global police force† to enforce the measures outlined above. In general, if the world does not take action in reducing human population, it will result to the depletion of resources. Earths life support system will all be under stress due to more people consuming more resources and numerous of organisms will be extinct. Scientific solutions that can help improve the environment will not be practiced until rules or laws are imposed and enforced. By decreasing population renewable resources will not be exploited beyond their sustainable yield; this will insure a sustainable lifestyle. Population control has been a major issue for years, and it is time to enforce policies to insure a sustainable lifestyle for the long-term future. A wise man once stated: â€Å"Instead of controlling the environment for the benefit of the population, maybe we should control the population to ensure the survival of our environment. † ~ Sir David Attenborough We will write a custom essay sample on What Policies Can Be Implemented to Reduce Human Population Growth?

A Genetics Definition of Homologous Chromosomes

A Genetics Definition of Homologous Chromosomes Homologous chromosomes are chromosome pairs (one from each parent) that are similar in length, gene position, and centromere location. The position of the genes on each homologous chromosome is the same. However, the genes may contain different alleles. Chromosomes are important molecules, as they contain DNA and the genetic instructions for the direction of all cell activity. They also carry genes that determine individual traits. Homologous Chromosomes Example A human karyotype shows the complete set of human chromosomes. Human cells contain 23 pairs of chromosomes, for a total of 46. Each chromosome pair represents a set of homologous chromosomes. One chromosome in each pair is donated from the mother and the other from the father during sexual reproduction. In a karyotype, there are 22 pairs of autosomes (non-sex chromosomes) and one pair of sex chromosomes. In males, the X and Y sex chromosomes are homologs. In females, both X chromosomes are homologs. Mitosis The purpose of mitosis (nuclear division) and cell division is to replicate cells for repair and growth. Before mitosis begins, chromosomes must be replicated to ensure that each cell retains the correct number of chromosomes after cell division. Homologous chromosomes replicate forming sister chromatids (identical copies of a replicated chromosome that are attached). After replication, the single-stranded DNA becomes double-stranded and has the familiar X shape. As the cell progresses through the stages of mitosis, sister chromatids are eventually separated by spindle fibers and divided between two daughter cells. Each separated chromatid is considered a full single-stranded chromosome. Interphase: Homologous chromosomes replicate forming sister chromatidsProphase: Sister chromatids move toward the center of the cellMetaphase: Sister chromatids align along the metaphase plate at the cells centerAnaphase: Sister chromatids are separated and pulled toward opposite cell polesTelophase: Chromosomes are separated into distinct nuclei After the cytoplasm is divided during cytokinesis, two new daughter cells are formed with the same number of chromosomes in each cell. Mitosis preserves the homologous chromosome number. Meiosis Meiosis is the mechanism for gamete formation and involves a two-stage division process. Prior to meiosis, homologous chromosomes replicate forming sister chromatids. In prophase I, sister chromatids pair up forming what is called a tetrad. While in close proximity, homologous chromosomes sometimes exchange sections of DNA. This is known as genetic recombination. Homologous chromosomes separate during the first meiotic division and sister chromatids separate during the second division. At the end of meiosis, four daughter cells are produced. Each cell is haploid and contains half the number of chromosomes as the original cell. Each chromosome has the appropriate number of genes, however, the alleles for the genes are different. The swapping of genes during homologous chromosome recombination produces genetic variation in organisms that reproduce sexually. Upon fertilization, haploid gametes become a diploid organism. Nondisjunction and Mutations Occasionally, problems arise in cell division that cause cells to divide improperly. Failure of chromosomes to separate correctly in mitosis or meiosis is called nondisjunction. Should nondisjunction occur in the first meiotic division, homologous chromosomes remain paired. This results in two daughter cells with an extra set of chromosomes and two daughter cells with no chromosomes. Nondisjunction may also occur in meiosis II when sister chromatids fail to separate prior to cell division. Fertilization of these gametes produces individuals with either too many or not enough chromosomes. Nondisjunction is often fatal or may produce chromosomal anomalies resulting in birth defects. In trisomy nondisjunction, cells contain an extra chromosome. In humans, this means that there are 47 total chromosomes instead of 46. Trisomy is seen in Down syndrome where chromosome 21 has an additional or partial chromosome. Nondisjunction may also produce abnormalities in sex chromosomes. Monosomy is a type of nondisjunction in which only one chromosome is present. Females with Turner syndrome have only one X sex chromosome. Males with XYY syndrome have an extra Y sex chromosome. Nondisjunction in sex chromosomes typically has less severe consequences than nondisjunction in autosomal chromosomes (non-sex chromosomes). Chromosome mutations can impact both homologous chromosomes and non-homologous chromosomes. A translocation mutation is a type of mutation in which a piece of one chromosome breaks off and is joined to another chromosome. This type of mutation occurs more often between non-homologous chromosomes and can be reciprocal (gene exchange between two chromosomes) or non-reciprocal (only one chromosome receives a new gene segment).

Application of Discounted Cash Flow

As per the ratio analysis determined from the financial statements of TNO Limited, it can be said that the net profit ratio of the company declined in the current unaudited period compared to that of the previous year by around 9%. Similarly, return on assets of the company also declined by around 10%, which indicates that the capacity to generate revenue from the assets is not sufficient. Working capital ratio of the company reflected 1.91, which was higher in the previous audited financial year indicating that the value of assets has been declined in the current year to meet the current liabilities. According to the financial statements of the company, it can be said that the net income reflected declining trend in the current financial year. It has been observed that the revenue of the company also reflected 58% decline compared to that of the previous year 2009 indicating reduction in the overall expected rate of return. During the current financial year, it has been noticed that the solvency ratio of the company declined in the current year, which was 0.50 in the previous audited period that may lower the return on investment and increase the cost of capital structure (Knechel & Salterio, 2016). On the contrary, liquidity ratio of the company reflected increased value in the current financial year, which reflects the ability of the company to convert resources in cash within short- term period (Lu, Wu & Yu, 2017). Considering the non- current assets of the company, it can be said that the value of investments has been increased in the current year. Increase in value of investments has been measured through properties, which was valued by directors as per the basis of financial year 2010 (Kou, Peng & Wang, 2014). Accordingly, it can be said that the investment valuation of the company reflected risk of decline in market value that may affect the true and fair view of the assets value. In addition, the account of intangible asset valuation reflects significant risk of correct valuation, appropriate amortization charges and value as per the current and fair market rates (Uechi et al., 2015). While planning and performing analytical procedures, it is essential to measure the significant risk present in the financial statements to assess the materiality and relevance of the financial performance of the company. In the present case, the areas that have been considered for significant risks are investments and intangible assets other than overall income statement and balance sheet. The investment account has been identified for significant risk since it covers a significant area of company’s asset and overall financial position. It is essential for a company to measure the appropriate and correct value of investments in accordance with the fair market value (Delen, Kuzey & Uyar, 2013). In case of TNO Limited, investment of surplus funds and property market is principal business activities therefore it is essential to conduct appropriate audit test on the value of investments. It is important to conduct detailed valuation of the investment together with the current mar ket value as well as interest rates along with the verification of accounting records of investment. On the other hand, valuation of intangible assets has been considered since it involves a significant area in the company’s overall asset resources. Since, TNO limited has been involved in research and development of technologies, it is essential to consider appropriate value of intangible assets as per the current market structure.

Response Paper 5 Essay Example | Topics and Well Written Essays - 500 words

Response Paper 5 - Essay Example The third chapter does not have ways gentle methods of controlling children in their â€Å"middle years,† but measures of living and comprehending a teenager’s way of thinking and behavior (Boston Womens Health Book Collective, 1978). This way, parents can assist their children in becoming the best of themselves. Bell emphasizes that this should not be achieved through fear or looking for approval, but through freewill. The authors’ guidance eases parenting by eliminating the struggling aspect. The third chapter entails real stories by parents and children, which frequently move the reader in terms of joy and pain. The emotional rollercoaster of the examples used eventually lead readers, especially parents, to learn that there is a kinder method of dealing with children in their middle years. The entire reading presents a communication formula for parents with children of all ages. This formula offers a combination of communication and behavioral learning skills and tools for parents. The tools allow parents to go further than their original fruitless response to a response that links and empowers children and parents (Boston Womens Health Book Collective, 1978). The problems children face during their middle years are not for them alone to deal with. This lesson pervades all through the reading. The authors emphasize the parent’s role in assisting his or her child in dealing with their problem. To handle this problem, the parent must first communicate with the child to learn about its source and effect on him or her. Acquiring problematic information from the child should certainly include realizations on the parent’s side regarding the child’s entrance into the public world. In addition, changing physically contributes to the effect or source of these problems. To help the child with them, the parent should consider

How Has Hooliganism (Spectator Violence) Permeated The World Of Essay

How Has Hooliganism (Spectator Violence) Permeated The World Of English Soccer - Essay Example The activities or manner is now known as soccer hooliganism which began in England near the beginning of 1950's (Giulanotti, 1994, Pp 12-13). In other European countries, parallel models of behaviour appeared about fifteen or twenty years later, near the beginning of 1970's. Italian fans fashioned a mainly obsessive variety of football support known as Ultras, who are now a chief force in the Italian sport and are widespread in a some other EU states. Football hooliganism is extremely complicated to describe, mostly for the reason that the media have been tremendously supple and undefined in assigning the "hooligan" tag to diverse occasions. The majority to mean disarray or confusion concerning football enthusiasts sees football hooliganism. Frequently this engages illegal actions and in the majority - but surely not all - cases takes place either at or just earlier than or after a football contest. Much football-throng chaos is impulsive, but a lot is set by bunch of criminals or gangsters who connect themselves to football societies and assemble to meet, and clash, from other societies (Crawford, 2004, Pp 42-43). It is frequently stated that hooliganism at football competitions turn out to be much more widespread in the 1970's and 1980's, with extra details of range of violence at contests. Nevertheless, yet again it is hard to know whether the quantity of chaos amplified or whether the rising media attention in, and exposure of, throng's chaos has destined it is reported faraway more often. Fundamental Problems Of Hooliganism Hypothetical explanations of football spectator hostility dwell in four different categories. First, there is the early on approach which accentuates that hooligan activities is a representative effort by blue-collar fans to reinstate some power over a game which they feel gradually more estranged from. Second, there is the ethogenic approach, which sees football watchers fighting as a custom appearance of mannish violent behavior. A third clarification, the planned segmentation approach focuses the implication of lower working class group arrangements and premature socialization as the key to perceptive the models of violent behavior shown by football hooligans. A concluding group of approaches see football viewer's chaos as a way of recompensing for the defeat of society sourced by post-war business and municipal expansion. This analytical research supplies a critical evaluation of some key features of the outcomes of comebacks to racism within British football. Other three features are recognized as: the conflation of racism with hooliganism'; the responsibility of antiracist operations within the sport; and the refutation of the trouble of racism within football sport. It is disputed that even as some of these interferences are praiseworthy, a common flaw is a malfunction to understand the environment and forcefulness of diverse racisms. This worry reflects more universal debates about the need to theories the intricacy and variety of the notion of racism and to recognize its opposing temperament. Writers in the past have stressed out the significance of touching away from extraordinary outsets of

The Adaptive Parasite Essay -- Viruses Virus Essays

The Adaptive Parasite Viruses are molecular sharks, a motive without a mind. They have sorted themselves into tribes, and they infect everything that lives. . . . Unknown viruses are coming out of the equatorial wildernesses of the earth and discovering the human race. . . . You might call AIDS the revenge of the rainforest. (Preston 160-61) After reading Richard Preston's ominous and threatening portrayal of viruses in his article "Crisis In The Hot Zone," one may be alarmed enough to invest in surgical scrubs and a space suit to wear as a permanent precaution against these evidently vengeful creatures. In truth, there are lethal viruses that exist for which there is currently no vaccine or cure, and there are various emerging viruses that are infectious to humans. However, despite this unfortunate and frightening reality, Richard Preston and other creative writers may be presenting a misleading depiction of a virus' actual niche within the global ecosystem, modes of infection, and relationship with humans. Science fiction novels and movies like "Outbreak" encourage the public to view viruses as microscopic monsters that exist to ultimately put an end to the human population, but viruses are not motivated by either logic or instinct to kill. In fact, viruses are not motivated at all. They have merely evolved to surv ive by utilizing the raw materials that the ecosystem provides. Viral pathogens have developed, through the selective process of evolution, to exist as parasites, and the inevitable ecological interaction between organisms, the ignorance and negligence of human behavior, and the cultural habits and customs of humanity has enabled a multitude of viruses to emerge and thrive within our population. V... ...S, we cannot expect to eliminate promiscuity or drug use; however, we can encourage protected sex and the use of clean needles. In addition, it would not be wise to eliminate the scientific advances provided by laboratory research on various animals or the benefits of constructing a dam or canal. However, we could, for example, take measures to control the massive propagation of mosquitoes in the event of the construction of a dam or canal. This relatively simple precaution will reduce the occurrence of diseases, such as Rift Valley fever and Yellow Fever, and may save thousands of lives. Although it is virtually impossible to completely prevent viruses from infecting humans, humanity's best defense against viral invasion is communication, education, and awareness to promote cautious behavior and to reduce the number of further outbreaks of deadly viruses.
