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 die. The difference between the two is called the rate of natural increase” (Stefoff, 1993). The rate of natural increase accelerated over the centuries due to industrialization that improved health care and food supplies in developing nations, therefore the birth rates increased in these nations while their death rates decreased. The demographic transition model proposes that birthrates will

The Social-Economic, Political, and Environmental Impacts of Unregulated Population Growth

...Anthony Mitchell Hessler 5/8/12 The Social-Economic, Political, and Environmental Impacts of Unregulated Population Growth Ladies and gentlemen of the Senate Select Committee on Intelligence, mankind is well on its way to answering a seldom asked yet vitally important question pertaining to its sustainability. "How many people can inhabit this planet sustainably?" This is a question that should have been looked into decades ago, yet the answer is still unclear. With no regards to what the answer may be mankind persists in rapidly escalating its population as if the worlds sustainable population capacity is limitless. With the numerous problems that currently plague mankind, overpopulation is perhaps the most threatening and overlooked issue. If current population trends continue there will undoubtedly be terrible repercussion to face in the future. Problems arising from overpopulation will eventually have a grim impact on the socio-economic systems and political systems of the world along with the environment as a whole, the worst of which could lead to the annihilation of the human race. This is why population growth should be a global concern that should be recognized, examined, and dealt with immediately. To understand the impacts of overpopulation one must first understand the concept of overpopulation. Overpopulation is a state wherein the population density of an area has grown large enough to exceed what would be the natural sustainable inhabitant capacity...

Human Population Growth

...Running Head: HUMAN POPULATION GROWTH Human Population Growth [Name] [Course] [Professor] Assignment • What is the current estimate of the worldwide human population at this moment? • Describe how this number is changing moment-to-moment, day-to-day, and from one year to the next. • Describe how the human population growth issue has and will impact the ecosystem. • Cite all references in APA format Human Population Growth There are several different estimates of the current world population, which vary slightly based on some assumptions about population estimates in different countries. 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. Thirteen minutes later, at 17:18 GMT (EST+5) Feb 13, 2009, the Census Bureau’s world population estimate was 6,760,298,598. That means, that in just 13 minutes, according to the US Census Bureau, about 1,005 more people existed on Planet Earth, or births outnumbered...

Social Change in Britain 1625-1688

...How far do you agree that population growth was the most important factor in causing social change between 1625 and 1688? * Population growth * Colonisation- North America colonies and also The Caribbean * The growth of London and its impact on economic development Throughout the 17th century Britain underwent substantial social change beginning most prominently under the Stuart monarchs Charles the 1st and 2nd. Many things changed drastically in and around this period which lead to drastic social change for example firstly there was a big spurt in population going from around 2 million inhabitants in Britain in the 15th century to around 5 million in the 16th, Britain’s great colonisation successes in the North Americas and the Caribbean building its economy and strength as a world power competitively and finally the growth of London and the impact it had on the rest of the country and Europe as it emerged as the no1 trading centre in the whole of Europe eventually which bettered the lives of many. I believe that population growth was by far the most significant factor in causing social change between 1625-1688; this is mainly because this was in a way a catalyst for change as the economy and infrastructure had to cope with the ever-growing and demanding population of Britain. For example the development of the national markets in the country only came about after the much smaller and local markets which existed where becoming too small, so this here lead to...

Human Population

...functioned to keep our population growth in check. However, since the last century, the human population had grown exponentially. Our survival is no longer threatened by other species and harsh environmental conditions. In fact, there is a new concern for the modern society—overpopulation. According to The American Heritage Science Dictionary, overpopulation is “The population of an environment by a particular species in excess of the environment's carrying capacity”. In addition, “the effects of overpopulation can include the depletion of resources, environmental deterioration, and the prevalence of famine and disease”. In the case of human overpopulation, human is the species that is in excess of the Earth’s carrying capacity. If human overpopulation is in fact a legit concern, then the effects mentioned in the definition above would most likely follow in the distant future. In order to prevent the negative consequences of overpopulation, humans must understand what specifically caused the population growth, how does population growth affect the world, what are the implications of overpopulation, and how to mitigate the effects of overpopulation. Although our population is a huge number compared to what it was in the past, we cannot conclude that we are overpopulated based on that comparison. In order to determine whether or not Earth is overpopulated with humans, we use a formula to calculate human’s impact on the earth. The equation is I=PAT, impact is equivalent to the product...

The Economic Impact of the One-Child Policy in China

...The Economic Impact of the One-Child Policy in China John F. Rodis EMBA International Economics Professor Jim Stodder October 15, 2014 The Economic Impact of the Single-Child Policy in China Thesis Statement: The single-child policy implemented in China more than thirty years ago to slow the rate of population growth, not only had a marginal effect on the growth of the population, but also had the unintended consequence of a long-lasting negative impact on the Chinese economy. Abstract: The Chinese government imposed a single-child policy 34 years ago in response to a rapidly increasing population that was determined to be unsustainable. Last November, the government ended the policy. A careful review of the literature regarding the efficacy of the policy as well as examination of other factors that could have affected population growth was conducted. The result of this review confirmed that the policy—in and of itself--had only a marginal impact on the growth of the Chinese population. However, the policy resulted in a significant change in the demographics of the Chinese population, with the result of China having a significantly older population than many developed nations, but one that aged at a much faster rate. However, unlike these developed nations, neither the Chinese people nor their government is adequately prepared for this rapidly aged population. As a consequence, there will be significant long-lasting negative consequences on the Chinese economy,...

Finch

...The purpose of this experiment is to test the hypothesis that small bird’s physical characteristics can greatly impact their species population growth over time. Using the Finch as a test subject for multiple trial runs on a simulated computer system we can alter the characteristics of the finch and run diagnostics for two completely different locations and set of experiments. This simultaneous testing and comparison will either prove or disprove the hypothesis that small bird’s physical characteristics can greatly impact their population growth. The base line for this comparison will be two islands labeled island A and B with population A1 of finches on island A and a population of B1 finches on island B. There will be two time allotments used to factor in the population growth for each sets of populations on both islands: beginning with a 100 year scenario and then followed by a 200 year scenario. Using extended timelines will reflect accuracy in the initial 100 year reading and or show that physical characteristics of finch birds only impacts population growth for a specific time period. Each island A and B will be of the same size and offer the same vegetation amount and size. However, the physical characteristics of each population will be altered to population A1 with a beak length of 14 mm and population B1 with a beak length of 11 mm. Given the consistency and amount of controls, compared to the one and only variable being a major physical characteristic of the...

World Population

...World Population The human population growth of the last century has been truly phenomenal. The world population passed 6 billion just before the end if the 20th century. Each year, about 90 million new people join the human race. This is roughly equivalent to adding three Canada’s or another Mexico to the world annually, a rate of growth that will swell human numbers from today’s 5.6 billion to about 8.5 billion by 2025. These figures represent the fastest growth in human numbers ever recorded and raise many vital economic and environmental questions. Is our species reproducing so quickly that we are outpacing the Earth's ability to house and feed us? Is our demand for natural resources destroying the habitats that give us life? If 40 million acres of tropical forest—an area equivalent to twice the size of Austria—are being destroyed or grossly degraded every year, as satellite maps show, how will that affect us? If 27,000 species become extinct yearly because of human development, as some scientists believe, what will that mean for us? If nearly 2 billion people already lack adequate drinking water, a number likely to increase to 3.6 billion by the year 2000, how can all of us hope to survive? answers are hardly easy and go beyond simple demographics, since population works in conjunction with other factors to determine our total impact on resources. Modern technologies and improved efficiency in the use of resources can help to stretch the availability of...

...Human Population Growth Concerns about Human Population Growth Population growth in India has grown significantly. According to Nova, “ In 1953, India was the first country in the world to launch a mass media campaign to spread the concept of family planning in response to population growth.” This step was aimed at an attempt to control and make the population understand the importance of not over populating as there was a significant rise in the population. Relationship between Population Growth and Environmental Impact As the population grows more and more, it impacts the environment with pollution such as garbage, waste and gases, the over use of resources, the constant use of farm land which takes nutrient out the soil, polluted water. These factors make the people of India prone to many diseases and sometimes fatality occurs as these factors are a result of population growth. How the human population is changing The human population in India is dramatically changing. According to About.Geography.com, “With 1.21 billion people, India is currently the world’s second largest country… Experts expect India to surpass the population of China, currently the most populous country in the world, by 2010.” So from this information, we can see that the human population is greatly increasing in India and over populating is and will pose very serious repercussions.
