Population Growth And Its Impact On The Environment

The first period was a very long period of time where the rate of population growth was very low. The second period was a shorter period of time that lasted up until about 1962 and it had a large increase in population growth. Finally the third period is the current period and it is where the population growth rate starts to decrease. The decrease in the population growth rate is due to the improving living and health conditions. Another reason for the growth rate going down is that parents, families, and other people are becoming more aware of the increasing population and the dangers or hazards that it will bring.

8) Developing methods of improved birth control affected women greatly. It allowed women more involvement transforming the way people procreate. Some countries feel strongly about keeping their procreating customs due to their important cultural traditions such as India’s Hindu tradition. Countries that changed during industrialism adopted the utilization of birth controls. However, they were not significantly affected compared to those countries that did not adopt such methods resulted in the populated increase.

Jack Goldstone’s New Population Bomb: The Four Megatrends that Will Change the World establishes the four megatrends that population growth will have in the world’s development. He established that the change in the current economic status quo that will be shifting from developed countries to developing countries, all this due to the uneven increasing of the world’s population. He argued that the trend of industrialized countries on population growth is decreasing compared to developing countries which would cause a drop in their working-age population (Goldstone, 2010).

Barry Commoner in “Poverty Breeds ‘Overpopulation’” begins his argument by stating that the population is clearly growing, but the resources we have are limited. Demographic transition is a characteristic found in Western states. If there is an increase in the standard of living than a population balance will occur, but this is not the case because of the death rates, birth rates, and infant mortality rates in poorer countries. These countries cannot afford education and new technologies that will help with this problem such as birth control. However, the increased standard of living is the first stage of the demographic transition.

Beyond a doubt we urgently need to address the devastating global issue of population growth in the United States America before we destroy our planet. We are facing many devastating economic problems, such as pollution, global warming, education, but the most critical is overconsumption. Overpopulation is a huge problem in the United States of America, which is causing us to run out of natural resources. The human race is already too large and is destroying the natural systems that support us. There are many solutions to this problem, but the common factor is controlling the human race. What can we do as a society to help contribute to controlling the population growth? “The United States is the most overpopulated country in the world” (Ehrlich).

The demographic transition model is a picture of population change over a period. In 1929 American demographer, Warren Thompson, observes the changes or shifts in birth and death rates in industrialized societies over a 200 year period. There are four stages of the Demographic Transition Model; Stage One (Pre-Modern) or High Flunctuating, up through the 18th Century and mostly agricultural, Crude Birth Rates (CBR) and Crude Birth Rates (CDR) are both high (30-50 per thousand). The population growth is slow and fluctuating. Infectious diseases and poor hygienic behaviors and not having clean drinking water mean few children nor adults can survive if there is little or no access to medicine. In Stage Two, Early Expanding, there is a rising population rate (CBR) increase and a (CDR) decline. High birth rates and low death rates mean life longer expectancy of a population resulting in population growth. It also means better sanitation conditions, better food quality and having the necessary medicine to combat illnesses. Transitioning to Stage Three, Late Expanding there is a decline in CDR and CBR. The population rises and birth rate fall. Living standards and income levels change for the better. Women have fewer children, become players in the workforce and seek higher educational levels along with their male counterparts. In Stage Four or Low Fluctuating , the human population stabilizes due to little CDR but more

It is a widely known fact that the population of the world increases by a great factor every year. However, not many people know what exactly is causing this upsurge. In the past century, the population has radically grown. The main things increasing the world’s population are medical care and infant mortality rates because both have changed drastically over the past century.

The population of the modern day society is in its most developed state, but the environment is in its worst. By continuing at such a rate, the planet would eventually become unable to support life for the future generations.

Demographic transition is a model based on birth rate and death rate in a populace. As indicated by this theory, each nation progresses through three distinct phases of population development. In the first stage, the birth rate and the death rate are high and the growth rate of population is low. In the second stage, the birth rate remains steady but the death rate decreases swiftly. Therefore, the growth rate of the population rises rapidly. In the last stage, the birth rate begins falling and tends to parallel the death rate. The growth rate of population is lingering.

With the introduction of agricultural and the rise of the Industrial Revolution, living standards have been elevated, while epidemics and famine have been diminished (prb.org). Ever since the 18th century, the human race has only continued to make improvements. For example, in the medical field. The creation of vaccines, medicine, and an increased knowledge of the spread of diseases have all helped to eliminate common causes of death, leading to overpopulation. Not only is overpopulation caused by an accelerated number of births, but it is also due to a decrease in the number of deaths, with 360,000 people are being born every day and only 151,600 deaths a day

Population growth has impacted the environment in my community because some of the farmland has had to been converted into residential areas, this would overall effect the amount of crops that this area of Iowa would be able to produce. Technological advances have impacted the environment the development of better farm tools has enabled farmers to grow more crops in a smaller area.

In ancient times up until today humans were still in stage one though now no country is any longer in that stage, as every nation has now moved at least to stage two and has therefore experienced many changes in their population according to().usually during the first stage people used to live on hunting and gathering to get food and when there was enough food for everyone population used to increase on the other hand if food was hard to find they usually saw a decline in their population. Whereas stage two it’s a stage of high growth which means there is a rapid decline in death rate yet having a rapid growth in the population, therefore having a high natural increase, this is mainly because of improvements in medicine or access to cleaner and healthier life. Usually, countries that experience an improvement in their standard of living for example because of industrial revolutions they tend to enter such a stage, such countries that entered this stage were North America and Europe. Then comes the third stage is known as the stage of decreasing growth whereby BR declines while DR stays declining and according to () NIR begins to moderate. In this stage, there still is growth though slower than stage two a society enters this stage when people decide to have fewer children which goes back to access to contraception and a better economic condition. Usually developed countries with a good job and standard of living are in such stages which according to () that their economic conditions encourage them to have fewer children. Finally stage four the stage of low growth in which there’s a very low BR and CR and the possibility of even a low NIR, A country reaches such a stage when CBR is equal to CDR and the NIR is almost zero. This happens because women enter the labor force and people will have a

The first stage is the pre-industrial stage that was seen before the industrial revolution. In the first stage the birth and death rates are high until the country goes to the next stage called the transitional stage. In this stage the birth rates stay high but the death rates decrease. This causes large population growth from having a higher life expectancy and technology improvements. The third stage is the industrial stage where the birth rate begins to lower closer to the death rate and population growth subsides(The Demographic Transition). This stage occurs when employment opportunities are increased for women to work outside of home, which makes children put off to focus on career(Brennan, Withgott 211). Also, having access to contraception and education make women less likely to have a lot of children, or have them earlier.The fourth and final stage is the post-industrial stage, where birth and death rates meet at low levels and stays stable(Brennan, Withgott 211). Stage one and four are both stable at rates of birth and death, however the difference between them is that in stage four the population has expanded, life expectancy is higher, and both rates are low(The Demographic

This decline in birth rates seems to be the result of adults starting to control their family size or even government action. With the implementation of urban societies and an industrialized culture, the want and need for many children had become less evident as children are seen as a hassle than a benefit. Urbanization and industrialization are more common with more developed countries so these countries have the ability to provide opportunities that are more attracting than raising children. These countries have the money to invest in controlling birth rates, unlike poorer countries that can't afford to help their people as much. It seems to be a pattern, that developed countries has already gone through each stage because of their power to shape and implement technology into their people daily lives, but it has lowered birth rates severely as well. The Demographic Transition model will end with the fourth and final stage, which is characterized by low birth rates and low death rates. This accounts for a very small increase in population and will add up to possibly over a thousand years of doubling time to replace the current

An increase in human population can influence our economy. Some of the factors that are affected are unemployment, poverty and the restriction of economic expansion. When the population increases, the cost of health, education,
