Population Growth Adam Pierce USH CP-D Mr. Clay Cushman March 22, 2016 Honor Pledge: Adam Pierce Population Growth is an issue that exists in today’s world that needs to be confronted before it becomes out of hand. The population itself has reached overwhelming numbers making it a problem that could turn to be dangerous. The amount of humans that the earth can support or the carrying capacity is slowly rising but at a much slower rate than the population growth rate. The increasing growth rate has its negative effects environmentally, agriculturally, socially, and economically and also has its positive effects nationally, and economically. The government is brainstorming and trying to come up with ways to decrease
Over population is an extremely serious problem facing the world today. According to an article from Newsweek in Oct. 2009 called “Where do babies come from?”, today’s world population has reached over 6.6 billion people. Also the article mentioned that in 2009 57.4% of all new born babies who were born this year came from Asia alone. This is an issue because over population can lead to hasty consumption of resources. China who has one of the largest population in the world with over 1.3 billion people, has taken a stance against over population.
Over the past years, there has been an exceptionally large national increase which has caused several population issues. These issues include: homelessness, deforestation and more fields being used to make space for shops and houses disrupting the biodiversity growth. Problems like this are caused when there is an abnormal increase in the birth rate where more babies are born; this is also known as a ‘baby boom’. This can occur when nations have more children as a whole and events like this normally takes place after an achievement – an example being when we won the World War Two. The country was relieved that the fighting was over so their instantly celebrated which is why more children were born. In the last 50 years alone, the population has doubled showing just how fast the population is actually growing and even though it may seem fortunate that there are less recorded deaths, this makes the Economical
Demographic and Environmental Timeline Demographic transition is the process by which a nation/country moves from high birth rate and high death rates to low birth and low death rates as the growth population in the interim (Weeks, 2005). Some of the nations that have gone through this transitions are; Canada, Germany, United States and England. The demographic transition to an industrialized society is harmful to the environment. Industrialized countries also have the largest ecological and carbon footprint comparative to developing/non-industrialized nations. Nevertheless, demographic transitions have some notable advantages. Countries that have gone through demographic transitions have low birth and death rates. Citizens in
Introduction: The reason I chose this topic is because in my country Ethiopia the rapid growth of population alarmed me, just around the 1965 our population was very low however in the past few years it has tripled form 20 million to over 100 million. This was when my interest in my countries population developed. Population is one of the conversational topics when talking about a countries profile, in view of the fact that it plays a huge role, in a countries work force, consumption and economy. I will be collecting data and modelling them to predict the population for the next 5 to 10 years. I will also be doing this for Kenya to see the relationship between the two countries to prove that this rapid growth of population is happening not only in our country but in our neighboring countries too.
The Demographic Transition Model is a simplification for the conventional process of shifts in population growth in our world’s countries. The Demographic Transition Model, also known as DTM, is derived from Great Britain’s model of their demographic cycle between the 1750s and the 1900s. It consists of five different stages, with the phases being low growth, increasing growth, population explosion, decreasing growth, and declining population. These phases are defined by a triple line graph of the crude birth rate, crude death rate, and the total population per one thousand people. The DTM applies to almost every country, but the different stages of the model the countries fit in varies. There are no countries remaining in Stage 1 anymore. Though, some are making it into Stage 5, and the addition of a Stage 6 is being considered.
According to Kunkel in “Global Aging: Comparative Perspectives on Aging and the Life Course”, the Demographic Transition Theory is a “... set of interrelated social and demographic changes that result in both rapid growth and aging of a population” (Kunkel 77). This theory essentially consists of stages that explain how most, but not all, countries undergo a stage of rapid fertility and death then see a decline in births, thus leading to a growth in the aging population.
The Theory of Demographic Transition Demography is the study of the components of population variation and change. Death rate and birth rate are two determinants of population change. Theory of Demographic Transition is comparatively recent theory that has been accepted by several scholars throughout the world. This theory embraces the observation that all countries in the world go through different stages in the growth of population. A nation's economy and level of development is directly related to that nation's birth and death rates. Population history can be divided into different stages. Some of the scholars have divided it into three and some scholars have divided it into five stages. These stages or classifications demonstrate a
ORLD population growth is facing three major chal- Fig. 1. U.S. Age Pyramid this increase will overload health care systems, significantly affecting the quality of life. Further, current trends in total health care expenditure are expected to reach 20% of the Gross Domestic Product (GDP) in 2022, which is a big threat to the W lenges [1, 2]: demographic peak of baby boomers, US economy. Moreover, the overall health care expenditures in increase of life expectancy leading to aging population and rise in health care costs. In Australia, life expectancy has increased significantly from 70.8 years in 1960 to 81.7 years in 2010 and in the United States from 69.8 years in 1960 to 78.2 years in 2010, an average increase of 13.5%1. Given the U.S. age pyramid2 shown in Fig. 1, the number of adults ranging from 60 to 80 years old in 2050 is expected to be double that of the year 2000 (from 33 million to 81 million people) due to retirement of baby boomers3.

With a growing population in every country comes with challenges and dilemmas. 7.4 billion humans are living on earth today and it is projected to be around 9 billion by the year 2040. Important aspects partake into population growth such as fertility, migration, and mortality. Other aspects greatly effect population growth, however; each country has their own rate of growth. In 20-30 years the world population will grow yet, at grow at a decreasing rate which still raises challenges for the over populated countries. I have great interest in China; I will be explaining and giving an outline on the possible problems that China is currently facing, future dilemmas and advice to advise China with solutions with the it’s challenges.
With the world running out of resources and struggling to sustain the recent boom in world population, governments around the world have been responding by trying to curb population growth with population programmes. Fertility Transition is a process whereby a country changes from a high birth rate to lower birth rate and is measured in terms of number of live births per 1000 women. This process usually occurs when a country is developing. Countries which are undergoing fertility transition in recent years have undergone a much more rapid transformation than when the present day developed economies underwent transition a couple hundred years ago. High fertility is often associated with poverty as there is a lack of education, healthcare and lack of sustainability within a country. The reasons which cause a country to experience fertility transition include; the changing of economy structure or economic growth, investment in education and the provision/subsidisation of contraception.
The other failing of these pessimistic models is in their conclusion that continuing population growth is inevitable. A phenomenon called the demographic transition (5) has been observed to occur as nations develop and standards of living rise. Before a nation develops, birth and death rates are generally steady, with the birthrate slightly higher and a low rate of population growth. As development begins, death rates fall sharply (because of increased health care) but birthrates remain steady, causing increasing population growth rates. During the demographic transition, further development and rising standards of living accompany a declining
Population Growth Over time, human population has increased and unfortunately has caused a lot of problems to the economy as well as to the environment. Many of the issues that population growth has affected are climate changes, consumption and waste, family planning, poverty, food and hunger, and changes to the economy.
The present rate of population growth is one of the most significant environmental issues we as humans are facing. The exponential growth at which the population is moving is having direct impacts on climate, energy, poverty, food, the global economy, and politics (Why Population Matters). The world population is currently 7.3 billion people and there is growing doubt that the planet is able to sustain human needs and resource consumption (Population Concern). The expansion of human population is impacting countries, societies, and cultures around the world differently. These differences can occur due to, environmental, political, and societal factors that can determine the severity of the issue and how the country decides to respond. The population is growing at exponential rates and can be expressed by calculating the double time, which is the number of years it takes for population size to double (Harper, Chapter 5). For developed countries, the calculated double time is longer than that of a developing country (Harper, Chapter 5). The first case study under analysis is that of Rwanda, one of the poorest nations in the world, which therefore has one of the lowest double time growths (Harper, Chapter 5). Food scarcity and violence are the stories of Rwanda’s fate and is outlined in Jared Diamond’s book, “Collapse”. The second case study being examined is China’s human population growth, which is not only negatively impacting its own country, but impacting others at a
