There is clear trend in population growth over the past two centuries. This has been a period of fast growth in the population. The one billion population point was reached only in 1800. It means before that period the population was very low. That could be explained by high death rates. However, from 1800 to about 1900 the population grew to 3 billion people. That is a big jump. This can be explained by better life expectancy, enhanced by good health care and the effects of industrialization. The population however kept increasing. This year 2012, the population has reached 8 billion. This newer growth rate was made possible by the decline in death rate, and increased life expectancy. This is still despite the low birth rates that has been necessitated by family planning measures. It is expected that within the next 12 years the population would reach the 9 billion mark. From there, the population is expected to stabilize. Firstly, family planning has managed to reduce the birth rates; however it triggered a longer life expectancy. This means there has been a huge decrease in death rate.
When people have few children, they can meet their health needs better than if the families were big. With medical care afforded to people, it means people live long periods of time. Many generations of people live at one time. With fewer children, the parents can invest their money in medical aids; they can afford good education for their children. The parents may also afford to invest more money hence leading to poverty reduction. With fewer children the parents save money to look after themselves in their old ages. That ensures that they live longer than previously done. So, family planning has brought about a reproductive revolution. If the population is big, there is likelihood of poverty, because there are many more people per fewer

Global Population Growth

...Global Population Growth Accordance to the United Nations demographers, global population already passed 6.9 billion in mid-2010. Also, population life expectancy is consistently rising decline (Engelman, 2010). Many industrial countries are now experiencing either slow population growth or completely. However, a lot of developing countries still continue to grow rapidly their populations to have large proportions of young people for working. Thus, 95 percents of population growth is appears in the developing nations today. Population growth has resulted in overpopulation on a national and world's level. It may limit future economic growth in high-fertility nations while population aging may do so in low-fertility ones. The population growth accelerates continuously increased demand for food, water, shelter, energy, health care, commodities, and careers. The most rapid rates of population increase often in countries where basic necessities are already scarce and that are least economically productivities and least ability to afford imports. Meanwhile, in many industrial and some rapidly developing nations, labor supplies are start to decline proportionally and sometimes completely decline. Many industrial and some developing nations have higher proportions of elderly unprecedented in demographic history, such as Japan which is 23 percents of current 127 million population being older than 64. Even if the life expectancies are expanding, there is no guarantee this phenomenon...

Global Warming and Population Growth

...Does global warming explain the relationship between the growing U.S. population and the rising average temperature in the U.S.? Purpose Statement The purpose of this study is to test the theory of global warming that relates the U.S. population growth to the average temperature increase in the U.S. The independent variable will be the rapidly growing U.S. population. The dependent variable will be the average climate increase in the U.S. The populations will be broken down into each individual state. Average temperature will be broken down into each individual state to get a clearer picture, since each state can have varying results with their relationships between population and temperature. This research project hopes to explain the growing U.S. population as the primary cause of the rising average temperature in the U.S. through the theories of global warming. Statement of the Problem or Research Question(s) Does global warming explain the relationship between the growing U.S. Population and the rising average temperature in the U.S.? The rising average temperature in the U.S. is becoming problematic. Global warming is taking its effect on this developed country. Letting global warming continue to run rampant without mitigation can be disastrous for the U.S. So questions need to be asked about what the main factors are, that are contributing to global warming in the U.S. Is there a direct correlation between the growing U.S. population and...

The usual caveat applies. _______________ This is a longer version of the paper prepared for IMRC 2006 conference on Global Competitiveness through Outsourcing: Implications for Services & Manufacturing, Indian Institute of Management (IIM), Bangalore, July 13-15, 2006. Abstract This paper analyses the implications of differing global demographic trends for India’s competitiveness in outsourcing and offshoring. It also briefly notes the implications of differing demographic trends among the Indian states. The paper argues that demographic complementarities with high-income countries provide India with one-time opportunity to sustain its growth rate and occupy all segments of global outsourcing and offshoring activities. India has used the labor cost advantage to gain reasonable market share in these activities. It however faces serious internal and external challenges in sustaining its international competitiveness, particularly with respect to labor cost. With sustained focus on human resource development, diversification and upgradation policies India can continue to atleast maintain its global market share, and help nurture globally competitive companies.

...two eats a species which eats plankton. Watson and Pauly explains that this indicator is more applicable than comparing global landings, which are declining at a moderate rate, as global landings do not account for illegal and unreported catches, the increase in fishing efficiency due to technology, and importantly, the changing composition of the catch due to sever depletion in stocks of large fish such as tuna and cod. Declining trophic level is an indicator of a significant structural change in food webs, and loss and degradation biodiversity, especially of stocks of larger fish. The findings are significant, indicating a severe decrease in the mean trophic level of global catch over the last half century. Watson and Pauly’s findings are summarized in Table 1, in which he contrasts global freshwater with marine fisheries and aquaculture, and shows a general...

...The current state of the biosphere shows unsettling trends. There is a need to meet these challenges, pursue more knowledge, and work as individuals and as a society toward long-term sustainability. Recent research has sent a message that global warming may not be a hypothetical threat, but a current issue warranting immediate action (Krogh, 2009). Global Warming There is a steady rise in carbon dioxide in the atmosphere. It is estimated that the average carbon dioxide concentration in the atmosphere has increased approximately 17% in the past 45 years (Campbell, Reece, & Simon, 2007). It is estimated that 20% of the excess carbon dioxide released into the atmosphere can be attributed to the burning of trees after deforestation. The burning of fossil fuel accounts for another 70-80% of carbon dioxide released into the atmosphere. Global temperatures are concurrently on the rise. Carbon dioxide lets radiation through the atmosphere, but retains some of the heat it generates (greenhouse effect). When carbon dioxide increases in the atmosphere, this greenhouse effect is enhanced, and too much heat from the sun is retained in the atmosphere. Some scientists, therefore, believe that elevated atmospheric carbon dioxide levels are responsible for global warming. Increased temperatures, in turn, may have deleterious effects on various species (Issues, 2009). Harlequin Frogs and Global Warming In 2006, the effect of global warming came sharply into focus.

Making Sense of Migration

...Migration Research Paper Name of Institution Name of Student Introduction Global economy as well as how society relates is greatly influenced by migration. Throughout history migration has facilitated human interaction which has led to the spread and advancement of humanity as a whole. Migration facilitates the movement of labour, the transfer of ideas, diffusion of new technology and interaction of various cultures. It is therefore important to understand the trends in migration and the factors causing migration. Migration trends also need to be understood in terms of the characteristics of immigrating groups. In so doing the cause behind the migration of these groups becomes evident. This research tackles the factors causing immigration whilst paying special attention to the role played by government policy and state action. This is mainly because emigration and immigration have, over the years, become state affairs transcending the personal requirements of individuals. Countries have adopted strict laws, policies and protocols that guide the emigration and immigration processes. The paper established a deep correlation between these laws, policies and protocols and the migration patterns. This was after analysis of available migration statistics as well as government policy and state action. The latter was found to have a rooted influence on the former either directly or indirectly. In the direct influence, government policy presents a push or pull factor that necessitated...

U.S. Education Today & Tomorrow

...U.S. Education Today & Tomorrow This paper reviews four important trends in our educational system today across America and discusses the impact of these trends on our future educational system. We live in an ever evolving world with constant changes that are affecting every aspect of our lives daily. Our educational system has not been immune to these changes and shouldn’t be since these changes and our ability to adapt to these changes will determine our future academic success and our place in a global society. Trend 1: Diverse & Older Population America has always been a melting pot of diversity, but current statistics show that in the near future minorities will become the majority percentage of the population (Pearson, 2010). Immigration, legal and illegal, have been substantial for a long time now and is changing the needs that educational systems have to address. For example, the need for qualified and minority teachers who can teach English as a second language will and does continue to grow (Pearson, 2010). Educators will have to adapt to this also by being more sensitive to various cultures and perhaps re-evaluate the current curriculum to promote multicultural literacy. Furthermore, the number of people that will retire will be doubled by the year 2050 and there will be fewer people of working age paying into the tax system that helps support education and elder services (Pearson, 2010). Because of this, financial constraints most...

One of the factors that concern the HRM area is the workforce demographics. In 1980s, baby boomers enter the workforce and started to operate in the job market. This boosts influence not only the organization, but also a country’s economy. Today, most countries in the world are facing population ageing due to the fact that now those baby boomers are approaching their golden age. In Wikipedia, population ageing is defined as a phenomenon that occurs when the median age of a country or region rises due to rising life expectancy and/or declining of birth rates. These occurs because of several factors such as reduction in the mortality and fertility rates, increased in life expectancy, migration of foreigners to a country and most of the time because demographically the population shifted towards aged population. This phenomenon will not only bring major implications to the social, economy and financial but also affect the HR function in a country(in general) and in an organisation (in specific).

Southwest Case Study

...Strategic Management Case Analysis: Southwest Airlines Southwest Airlines Co. (Southwest) is often cited as a success story in terms of strategic management. Southwest is a passenger airline that provides scheduled air transportation in the United States. Primarily, the company offers passengers low-fare, point-to-point air transport services in 72 cities in 37 states all throughout America (MarketLine, 2012). Southwest is headquartered in Dallas, Texas, and has about 45,392 employees as of FY2011. For FY2011, the company generated revenues of $15.658 billion, increasing by 29.4% over FY2010 (MarketLine, 2012). Southwest reported net profit of $178 million in FY2011. It must be noted that the airline industry is famed for its cut-throat competitiveness. However, since its inception in 1971, Southwest has been able to steadily rise to the top of airline rankings due to its Low Cost Leadership strategy (Muduli & Kaura, 2011); Box & Byus, 2009). Southwest also consistently offers on-time arrival that, combined with low-priced fares, makes it highly favorable for passengers. Southwest is able to achieve its strategy by using a linear, point-to-point network and does not have an airport hub (Tierney & Kuby, 2008). As a result, the company’s aircraft are seldom idle while its competitors spend prolonged idle time while passengers switch planes at the hub (Tierney & Kuby, 2008). Because of the impact of this strategy on passengers and the industry as a whole, competitors tend to...

...Global Over Population Introduction Global population has soared past 7 billion. Every second of every day, our global population grows by three people. In 2010 the average person lived 69 years, whereas in 1960 the average life expectancy was 51. Each year there are more than 1.43 million unplanned births in the U.S. At the current rate, the population of the least-developed countries will double in the next 31 years. Today about 783 million people lack access to improved drinking water: that's about a tenth of our world's population. Overpopulation is beginning to degrade the quality of life for many, and is significantly depleting precious natural resources that we need to survive. The first billion took from the dawn of humanity until 1830. The second billion took only 100 years -- from 1830 to 1930. Three billion more arrived in the next 60 years. The next billion will take only 13 years unless there is a tremendous effort to slow world birthrates. The ideal population of the United States was what it was around 1950, when factors like housing, jobs, and pace of life, crime, and pollution were at comfortable levels. Some say there is a connection between runaway population growth and human suffering. It has been said that while recent environmental victories are very important, they will become meaningless if demand on the earth's resources continues to escalate as it has in the last century. In this essay we will cover concerns such as 1. The human footprint...

Global trends will be a major consideration when forming our strategic HRM policies for the next 10-15 years. The NIC’s treatment of demography identifies four trends that its authors argue will substantially influence the future of international relations – to 2030 and beyond: * Aging, which they call “a tectonic shift” for developed countries but also increasingly many developing; * Youthful Societies and States, which they note is a shrinking but still-significant number; * Migration, which is expected to be more cross-border and increasingly common; and * Urbanization, which is a continued trend that will accelerate and take center stage as its side-effects impact Africa and parts of Asia. * Changing Age Structures By 2030, nearly all of Europe, South Korea, Japan, and Taiwan will have a median age of 45 or older, compared to just Japan and Germany today. This “pensioner bulge” will create labor and health system challenges and has also been cause for concern for some national security watchers. But the NIC points out that these predictions are “speculative,” since the trend is unprecedented and advances in healthcare may play a mitigating role. On the flip...

...at around US$2.4 trillion. Whilst most of us cannot visualise such huge amounts, it does serve to give some indication of the scale of international trade today. This global marketplace consists of a population of 6.6 billion people which is expected to reach 10 billion by 2050 according to the latest projections prepared by the United Nations. Global wealth is increasing and this is reflected in higher demand. Increasing affluence and commercial dynamism has seen nations across Asia, Central and Eastern Europe emerge as high growth economies. Increasing affluence and demand simply means that consumers will actively seek choice, with the result that globally competition is intensifying as companies compete to win the battle for disposable income. Population growth and increased affluence together have helped create a ‘global youth culture’ – teenagers now account for 30 per cent of the population globally. In many countries, more than half the population is pre-adult, creating one of the world’s biggest single markets, the youth market. Everywhere adolescents project worldwide cultural icons, Nike, Coke, Gap and Sony Walkman, as well as Sega, Nintendo and the Sony Playstation. When ‘virtual reality’ is commonplace, the one-world youth culture market will exceed all others as a premier global market segment. Parochial, local and ethnic growth products may face difficult times. Older consumers are also increasingly non-national in their identity, if not in their...
