...RAPID INCREASE POPULATION INTRODUCTION: It is often suggested that rapid population growth, especially in developing countries, correspondingly intensifies environmental degradation, which must therefore be mitigated by reducing the rate of population growth. The validity of this assumption can be tested by means of an algebraic identity that relates the amount of a pollutant introduced into the environment to the product of three factors: population, "affluence" (the amount of goods produced per capita), and "technology" (the ratio of pollution generated to goods produced). For several forms of pollution that have a known origin in a specific production process (electricity production, use of motor vehicles, and consumption of inorganic nitrogen fertilizer), it is possible to compare the inferred rate of increase in pollution levels with the rate of population growth in developing countries. The results show that the rate of increase in pollution is largely determined by the technology factor, which governs the amount of pollution generated per unit of goods produced or consumed. This observation extends earlier evidence that both the increasing levels of pollution observed in developed countries and the results of efforts to reduce them support the view that the decisive factor determining environmental quality is the nature of the technology of production, rather than the size of the population.

What would you include in a brief summary on the history of the modern environmental movement, from the 1960s to the present? The desire to make profits have grown astronomically from the 60s’ until now. Earth’s resources are now being used as cheaper way to supply the population with certain needs that may be taking away from the natures Forrest and water supply. These resources are not being replaced with other natural resources in fact businessman and corporations with the greed for profits create pollutants which are dumped into the earths rivers and atmosphere. The cutting down of trees from the earth’s forrest are leaving animals without homes and removes natures own oxygen for our own selfish pleasures.Fresh water resources like certain streams and rivers are now being polluted with our human waste. The pollution of none natural resources are covering certain beaches of the earth today. The creation of these non natural resources leave smog in the earth’s atmosphere today. 2. Explain the primary concern over exponential population growth. What promotes exponential population growth? What constrains exponential population growth? The primary concern of exponential growth,would be that as years continue on the earth so does the human population increasing accumulation. With this...

...worldwide estimated human population at this point in time is 6,798,328,762 people (U.S. Census Bureau, 2009). This number constantly changes due the birth or reproduction of human life. Another contributing factor to human population changes is the death rate. Looking more closely at what sparks birth and death rates to change, we find that different eras or historical events lead to changes in the human population. One event that generated large a large death toll was the Black Plague (Lewis, 2004). A more recent event that could potentially spark a decrease in population would be the Pandemic Flu. An example of a historical event that contributes to increases in human population is the Industrial Revolution. The industrial revolution created a higher demand on products and services which called for families to expand in order to cover the needs. Another example is the creation of medications that cured illnesses that were considered incurable in past years. One such medication is the antibiotic. When the antibiotic was invented, it cured ailments and illnesses that had at one time been considered terminal. It also prolonged the life of many individuals, which ultimately led to less death. Other contributions included enhancements to sanitation, and agriculture (Lewis, 2004). These enhancements helped by preventing infection and increasing the health of the population. Both of these enhancements assisted in increasing the lifespan of humans. The human population growth issue will...

...AUSTRALIAN ENDANGERED ANIMALS – CAUSED BY HUMAN IMPACT The Department of Sustainability, Environment, Water, Population and Communities (2009) asserts that Australia has 143 endangered animals, several of them are rare and only found in this part of the world. There is a serious concern about this endangerment because a number of these animals could be at a high risk to become extinct. It could cause loss of biodiversity, misbalance in food chains, and irreversible changes to environment. As long as some suggest that this issue could be a natural process, there are many who maintain that human impact is more responsible for increasing the number of endangered animals. There are many convincing arguments that the human impact has intensified the endangerment of animals. First of all, the introduction of invasive and feral animals produces harmful consequences in native species due to predation, rivalry for food and shelter, and transmission of diseases (The Department of Sustainability, Environment, Water, Population and Communities 2011). The endemic Numbat have been hunted and killed by red foxes brought from Europe, as a result Numbat population is reduced significantly. Nowadays, they are found only in South Western Australia. Furthermore, the habitat destruction has increased the rate of endangerment. It can occur because of reduction in the space availability for native species. Changes in the original habitat especially by agricultural practices and logging are held...

...Demographics – Impact of the Aging Population Your Name Here University of Phoenix HCS/490 Health Care Consumer – Trends and Marketing Demographics Demographics is the study of the population as it pertains to particular geographic areas concerning age, sex, race, income, disability, and a host of other determining factors. Demographics of a population can be obtained through various means, the of the most reliable is that obtained through the government census. As instructed in Article 1, section 2 of the Constitution of the United States, the Constitution requires a census of the population every 10 years. The purpose of this is to obtain a correct count of the population for determining the number of representatives for each state to seat in Congress. The government also uses the collected information and breaks the demographics down according to state, counties, cities and towns for a true picture of the population of these areas. With this being known, the government uses this information for the distribution of monies for the various demographic needs of the population. Each individual of every age, sex, race, income, and disability has different needs, and as a result affects each geographic location differently. The Demographics of Monroe County, Michigan Monroe County, Michigan has a population of 152,949 as of the 2008 population estimate (U.S. Census). This reflects an estimated population increase of 4.8% from the 2000 census...

...economic tools and concepts that relate to the health care field. When discussing the current nursing shortage, and the nursing shortage that will continue through the future, scarcity, supply, and demand are just a few of the important concepts to address. According to Explorehealthcareers.org (2012), “The United States has a serious shortage of practicing nurses” and “demand for frontline workers is expected to increase 50% over the next five years.” This paper will explore scarcity, supply, and demand and how these relate to the current and future nursing shortage. Scarcity Scarcity exists when the infinite human wants outweighs the limited amount of resources available ("The Problems of Health Care", n.d.). Scarcity exists within the health care field when discussing the nurses, the need for nurses, and the amount of nurses that are available to fill the number of positions available. There are many reasons that have led to the scarcity of the nursing resource. The amount of nursing schools and nursing instructors are not able to keep up with the amount of potential students, nor the need for more nurses; there are greater opportunities for nurses to expand their careers and move out of hands on nursing; there are more people entering the health care arena who will need health care and nurses to provide that care (American Nurses Association, 2014). The nursing shortage can lead to a decline in quality of care as well. According to American Nurses Association (2014)...

...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 we...

...Ecology and Population Growth University of Phoenix Natasha Griffin SCI/230/Christine Rogers February 10, 2012 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. According to the U.S. Census Bureau (2006), the current human population worldwide is “6,783,673,491 as of June 1, 2009 8:50 a.m.” In the 1960’s the population was growing at a staggering rate as a result of new medicinal resources, as well agricultural development (Nova, n.d.). The population grew to around three billion people. In just 14 years the population grew by another one million people. Recently the trend in population growth has been increasing by one billion people every year. According to Nova (n.d.), “Over the next half century, our numbers will increase again, likely to a staggering nine billion people”. Describe how the human population growth issue has and will impact the ecosystem. Looking at the graph it seems as if the rate of human’s growth is decreasing dramatically. Figure 1 World Population Growth Rates: 1950-2050 Source: U.S. Census Bureau, 2006. The reason for the dramatic decrease in the world population is in part an effect of natural disasters (U.S. Census Burearu, 2006). Currently the human population is straining the use of our natural resources. Americans use the highest numbers in comparison to Europeans (Nova Global...

World population growth is increasing,and is already causing many problems. It is projected to continue growing in some parts of the world whilst others stabilise, with some estimates putting the final population of the world as high as 12 billion (it is currently half that). Copyright S-cool Managing population growth Population growth brings with it many pressures. The environmental impacts are discussed below, however, there are many other effects of this rapid growth. The main areas of rapid population growth are: Asia, Africa and Latin America. These developing areas are moving through the demographic transition model from stage 2 to stage 3. In other words, during the second half of the 20th century their death rates fell, whilst the birth rates continued to be high. This was due to improving health care and sanitary conditions. As a result of the BR being so much higher than the DR, the population of these areas has exploded. This population growth in the LEDC's could lead to a range of problems, which are listed below: Urban areas will become increasingly overcrowded...

...the past have to say of our increasing population. One of the famous population theorists of that time is Thomas Malthus. In 1798, Malthus proposes his own theory about population. According to him, human populations grow exponentially while food production grows at an arithmetic rate. Thus, if the increase in our population is not controlled properly, then the number of the people would increase faster than the food supply. He stated that if this growth rate is allowed to continue, it would lead to a food shortage. To solve this problem, he proposed three solutions. The first one is positive check. This method increases death rates due to wars, famines, disease, and natural disasters. Preventive or negative check is the other one. It lowers the birth rate which is accomplished through abortion, birth control, and celibacy. The last one is moral restraint which is refraining from marriage until the time when a person is capable of supporting a family. This two hundred-year-old theory is now happening these days. It predicted the problems of food shortage that the world is experiencing today because of the uncontrolled increase in population. Still, I cannot fully agree with Malthus because there are things that he forgot to take into consideration when he formulated this theory. One is the ability of man to increase the food production as stated by Marx. He failed to recognize man’s ability to use science and technology to solve these population problems like the possible...

...zombies are no longer only killing the humans at a rate of 5 per day. According to the UN press conference, the new rate of change of the human population can be modelled with the following equation. This equation shows that the rate of change of the human population can be expressed by minus the population of zombies. Consequently, this new model predicts that the zombie population will grow exponentially. It is possible to use this equation to find out how quickly the human population is changing for any number of zombies. For example, if there are 50 zombies, the rate of...

...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 early...

...Expert Views on Increasing Population World’s population growth is close to seven billion, the rapid growth is raising concerns with many experts. Experts today are arguing their views on the issue of population growth. While both Alon Tal the author of “Overpopulation Is Still the Problem” and Robert Walker the writer of “Overpopulation Is Not the Problem? Really?” state that population growth is a problem, the author of “The overpopulation myth” Fred Pearce and the author of “Overpopulation Isn’t The Problem: It’s Too Few Babies” Joel Kotkin disagree. This paper will examine the work of these four writers to analyze their perspective whether population growth has negative or positive consequences. Lack of food, reduction in living organisms, ecological and environmental problems as claimed by Tal are the outcomes of population surplus. He asserts that deterioration of China’s natural capital was part cause of China’s food crisis during 1958 and 1961 that resulted in more than twenty million people staving; as many died due to lack of food. China’s food crisis should teach the world a lesson states Tal that the outcome of taking no notice to the lack of natural resources and growing population is severe. He agrees that China’s one-child policy was not popular with the china’s people, however, it prevented many deaths caused by starvation. Tal goes on to explains that in the developing regions of the world one in eight people suffer from continues undernourishment...

...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 you...
