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 will continue. Due to climate change and the risks it affects to global food security, health, and security, leads at least one major potential challenge to falling mortality rates worldwide. In 2005, fertility stopped falling and has risen since then in the population of industrial nations as a whole. However, in most of developing countries, fertility is falling quite slow, and they are…...

Problems with Population Growth

...Problems with population growth For two consecutive years since 2009, the population has grown just 0.7% a year, down from annual increases around 1% in previous years and the lowest since the late 1930s. The U.S. gained 2.2 million people from 2010 to 2011, fewer than the 2.8 million added a decade earlier, reaching a total of 311.6 million. (El Nasser, 2012) The recent rapid increase in human population over the past two centuries has raised concerns that the planet may not be able to sustain present or larger numbers of inhabitants. Steve Jones, head of the biology department at University College London, has said, "Humans are 10,000 times more common than we should be". (Gibbens, 2011) Population growth has caused many environmental problems, such as rising levels of atmospheric carbon dioxide, global warming, and pollution, all aggravated by the population expansion. In 1800 the economy passed one billion inhabitants. But the rising numbers are having some serious effects, population growth has already caused climate change, rising sea levels, extinction of wildlife and expanding deserts. Existence has been fuelled by the depleting resources that are fossil fuels, minerals, groundwater, soil, forests and fisheries rather than natural income. (Martin, 2011). Other problems associated with overpopulation include the increased demand for resources such as fresh water and food, starvation and malnutrition, consumption of natural resources faster than the rate of......

Advantages of Population Growth

...Population growth in Australia Executive Summary According to Treasury's most recent Intergenerational Report, Australia's population should climb from 22.7 to 36 million by 2050 due to a combination of a fairly high birth rate by western standards and significant levels of immigration. (ABC, 2011) Prime Minister Julia Gillard seems to be supportive of this rapidly growing population, as she stated in a recent press conference that ‘population growth is crucial for the economic welfare of our nation’. Economic welfare broadly refers to the level of prosperity and living standards of an individual or group of persons, and Julia Gillard’s statement is very valid in that Australia does heavily rely on an increasing population for economic welfare, in order to maximise the economic welfare of individual’s society. Population growth can introduce numerous benefits in the form of economies of scale, economic growth and a good dependency ratio, and these arguments will be discussed further in order to prove the validity of Julia Gillard’s statement. Economies of scale Economies of scale are the benefits to a firm (decreasing average costs of production) as the firm increases in size. Population growth permits the development of economies of scale for Australian firms because with more people there is more labour for production and more money to spend on production, increasing the quantity produced. This means that the unit cost of production decreases, resulting in more......

Population Growth Research Papers

...------------------------------------------------- Population growth From Wikipedia, the free encyclopedia The estimated size of human population from 10,000 BCE–2000 CE. 'Population growth' refers to the growth in human populations. Global population growth is around 80 million annually, or 1.2% p.a. The global population has grown from 1 billion in 1925 to 7 billion in 2012. It is expected to keep growing to reach 11 billion by the end of the century. Most of the growth occurs in the nations with the most poverty, showing the direct link between high population growth and low standards of living. The nations with high standards of living generally have low or zero rates of population growth. Australia's population growth is around 400,000 annually, or 1.8% p.a., which is nearly double the global average. It is caused mainly by very high immigration of around 200,000 p.a., the highest immigration rate in the world. Australia remains the only nation in the world with both high population growth and high standards of living.

Ecology of Population Growth

...Chapter 2: The Ecology of Population Growth Review Essay by Max Kosusnik Earth’s population has increased by the billions at rates deemed too quick for us to be capable of controlling. We, as a race, grew to our first billion in 1804. In 1927, only 123 years later, we had reached our second billion. To make matters more substantial, it only took 33 years until we had reached our third billion, in the year 1960. The rate would speed up so much that, on average, every 13 years our world’s population would reach another billion, getting us to 7 billion in 2011. This fast paced growth comes with many consequences. Human demands will and possibly already have overrun the amount of our natural support systems, and our food supplies, such as our fisheries, grasslands, forests, soils, and aquifers. If our demands increase over the sustainable output these resources provide for us, then it will result in overfishing, overgrazing, overcutting, overplowing, and overpumping. A recent demographic projection by the U.N. shows that the world’s population will grow to well over 9 billion by 2050. Although many believe this will materialize, it is unlikely due to the hardships we will face increasing the food supply, global warming, and water shortages. Although world population growth has slowed down from the peak of 2.1 percent in 1967 to 1.1 percent in 2011, it is still unclear whether the population growth has slowed due to the shift to smaller families or the opposite, that......

Perspectives on Population Growth

...PERSPECTIVES ON POPULATION GROWTH Based on the current trend, there will be a total to about 9.2 billion people on the earth by mid-century, fuelled by the birth of 220000 children a day and falling mortality rates (Population Institute, 2014).  This estimate raises questions about the future of humanity and the planet we inhabit. The debate about an optimal size for human population is one that has waged over the years. The question is fundamentally about sustainability; whether the resources that drive our lives can be sustained indefinitely can support humanity in the long term. We operate on the assumption that, on a finite planet, nothing physical can grow indefinitely. As our population grows, the fewer resources there are for each of us and members of other species with which we share the planet. Because of the finite nature of the resources and the ability of our planet to provide us infinite resources, we need to, carefully consider some aspects of our existence, like our consumption, acceptable living standards, what technologies make best use of the resources available and explore ways to preserve the ecosystems on which we depend. The primary concern regarding rapid global population growth includes aggravated poverty, starvation, water scarcity, political & social instability and depletion of natural resources. How will we feed 9.2 billion people when high food prices and the global economic recession have pushed 100 million more people than last year......

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......

Population Growth

...Population Growth and Ecological Footprints The population size (N) of a species at any point in time (t) is determined by its size at (t-1), its per capita birth rate (b), its per capita death rate (d), and immigration and emigration. Each of these values is, in turn, affected by a huge suite of biotic and abiotic conditions. Human populations are governed by these same variables. In this laboratory, you will use models of population growth to understand how population growth is affected by changes in b and d, and why the actual values of b and d are important. You will also explore some dimensions of human impacts on the environment. A model is a mathematical description of how one thinks a system works. For a population growing at a constant rate, where b and d never change, an appropriate model for population growth is the exponential growth model: dN/dt = rN where r = b – d, assuming that immigration and emigration are negligible. This is a density-independent model since neither b nor d change with increasing population size. Conversely, the logistic model is a density-dependent model, where b and d change with changes in the population size: dN/dt = rN [(K-N)/K] where K = carrying capacity of the environment. In this lab you will use a simple Excel spreadsheet model to explore how population size (N) changes as b and d change under the two different growth models, exponential and logistic. The spreadsheets have areas that......

The Impacts of Population Growth

...Running Head: THE IMPACTS OF POPULATION GROWTH 1 The Impacts of Population Growth INR2012 THE IMPACTS OF POPULATION GROWTH At the beginning of the first millennium A.D., the world’s population stood at 300 million people. The Industrial Revolution in the 18th century raised living standards and spurred growth; in the year 1800 the world’s population reached one billion. The 20th century was marked by health advances that improved life expectancy and increased the number of children that would reach adulthood and bear their own children; in 1927 the two billionth baby was born, in 1960 the third, in 1974 the fourth, in 1987 the fifth, and in 1999 the sixth. We now stand in the year 2012 with a world population of 7 billion. The exponential rate at which population is increasing is a global concern. Economist and demographer Thomas Malthus voices that population will naturally exceed its resources and then famine, war, and disease will put a check on its growth (Malthus, 1798). In the face of these concerns, various states are formulating and implementing policies to control their population growth in order to achieve socioeconomic sustainability and ensure a better quality of life for future generations. “Population is determined by the interplay of two factors. One is the birth rate, or the number or people being born, and the other is death rate, or the number who......

...Population Tremendously Growing in DFW “Dallas-Fort Worth-Arlington added 108,000 people, the third-largest population increase in the nation behind Houston and New York” (Campbell 1). Population growth is the increase of individuals, which has increased tremendously in the DFW area. As a metroplex we should care about the population increasing because we are running out of resources, we are overcrowding and expansion of diseases. Even though it boosts the income of the economy, the alarming rate of population growth in the DFW area threatens the community. In order to improve the rate of population growth in DFW, the city needs to better Education, women empowerment, and Family planning. DFW has been the most growing metroplex in the country besides New York and Houston. The DFW area is full of attractions and businesses, this area is great for doing businesses. Therefore, people of cities are moving to DFW for their business or the attractions DFW has. “Texas added more than 387,000 residents between July 1, 2012, and July 1, 2013, and more than 1.3 million since April 1, 2010, significantly more than any other state” (Young 1). DFW’s population keeps increasing, therefore, its getting worse and worse for our community. The population is increasing because a lot of immigrants from Mexico are coming our way and increasing our population. The Hispanic population is is getting closer and closer to the non-Hispanic population. “Hispanics made up 38.3 percent......

The Problem of Human Population Growth

...Human Population and Environmental Problems by PAUL R. EHRLICH, Ph.D.(Kansas) Professor of Biology and Director of Graduate Studies, Department of Biological Sciences, Stanford University, Stanford, California 94305, U.S.A. rather small number that are thought of as 'important' forms of wildlife—will have a dramatic negative feedback effect on the capacity of our planet to support human life. This is because, although politicians and laymen tend to focus attention on air pollution and water pollution as the most serious environmental problems, in fact the most devastating of all is the destruction of the life-support systems of our planet. These are the natural ecosystems that provide us with a series of public-service functions without which we cannot persist indefinitely on this Earth—such functions as maintaining the quality of the atmosphere, controlling roughly 99 % of the potential agricultural pests, recycling of our waste products, and many other services that we cannot perform for ourselves (Ehrlich et al., 1973). The third message which I would like to give you is that the time for research as a major approach to the world's problems is long past. If you are trapped in a forest, downwind from a forest fire, and it is raging towards you at ten or more kilometres per hour, you do not immediately convene a committee to study reforestation—you call for water. In human society, calling for water basically consists of promoting......

Global Population

...The videos Global Aging and Census: U.S.'s Aging population gave brief overviews of the global population crisis. By 2050, the population of 60 plus is expected to exceed the population of those under 15. This is uncharted territory, and the implications will be costly. The economic ramifications must be examined, including the use of tax and transfer programs (Medicare, Medicaid, and Social Security). Policy and health reform need to take into account issues of the aging population (International Monetary Fund , 2011; Wall Street Journal, 2014). This problem must be solved now. If we ignore this problem, a crisis is sure to be around the corner. The National Council of Aging (n.d) has been actively lobbying for programs to support the needs of the aging, such as the Supplemental Nutrition Assistance Program and Savvy Saving Seniors. The projected growth for the 60 and over population in Arizona is expected to greatly increase in percentage by 2050. Most alarming to me is the population of adults over 85 is projected to grow from the 2000 census of 68,525 to 265,274 in 2030. This is a staggering statistic. This growth is also apparent in the national dependency ratio, which includes those ages 18 and below and 60 and above. The dependency ratio is projected to increase from 74 to 85 between 2020 and 2050. This places an enormous burden on the working class (Administration for Community Living, n.d.). It addition to this burden, the elderly population has been......

Most census data for various countries is at least two years old (and may be older). Population models have to account for growth since that data was collected. They also have to adjust for some errors in that data (miscounts, birth and death rates, migration, etc.). Given the variability of the base numbers and the differing estimates of errors, it is not unexpected that there are slightly different numbers. According to the US Census Bureau’s International Data Base (IDB) population clocks, at 17:05 GMT (EST+5) Feb 13, 2009, the world population was World 6,760,296,593.

Ecology and Population Growth

...Ecology and Population Growth The growth in human population has affected Earth’s air, forests, land, animal habitats, water, and climate. The change in climate has been caused by the amount of greenhouse gases from the increase in industry, and auto emissions, the amount of energy coming from the sun, and the properties of the Earth’s surface. These factors have a warming effect on the planet, called global warming which acts like a blanket trapping this solar energy, and gasses close to the Earth. This causes river and lake water levels to be lower in arid areas, and glaciers to melt causing floods. With the temperatures predicted to be up one hundred degrees Fahrenheit worldwide over the next one hundred years, threatening extinction for thousands of plant and animal species. Because of agriculture clearing, and aggressive logging over the past 30 years almost half of the world’s forests have disappeared. Land has been altered for forestry, farming, pastures, roads, industry, and houses. The amount of land altered for our use totals half of the world’s total land. Habitats are threatened by human growth, everywhere on Earth oceans are overfished causing extinction for some species already. Rising temperatures has caused Coral Bleaching, coral reefs are home to thousands of species, and protects the shorelines of some islands. Half of the world’s coral reefs and islands whose shorelines they protect will be gone, as will thousands of animal species. The Earth is covered......

Population Growth

...POPULATION GROWTH AND THE PRESSURES IT PLACES ON EARTHS RESOURCES World population has rapidly increased in the last century and has now reached a staggering seven billion, raising alarming concern for the sustainability of our planet. Rapid population growth and economic development are increasing the demands on natural resource stocks (Orimoogunje, 2011). Sub-Saharan Africa is projected to become the primary source of population increase (United, 2002), yet lack of infrastructure represents one of the most significant limitations to economic growth, environment management and achievement of the Millennium Development Goals (Paul M. Pronyk, 2007). Uneven resource consumption is wasteful and contributes to the maldistribution of basic resources in developing countries. Studies show that high income earning countries constitute a smaller number of the population, but consume nature’s resources much faster than developing countries; this adds to the inequality of the world and compromises the stability of our ecosystems to support population growth (Kemp, 2004). The global population is expanding and human resource consumption rates are increasing adding to the environmental problems we face today. During the last century alone, global population in the world has grown from 1.65 billion to 7 billion (World population). In the gap between when my parents were born and I was born the population has roughly doubled from 2.25 billion in the late 1940’s to 4.5 billion in the......
