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.
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
Population growth has been running rampant in developing countries for the past century due to a lack of education, medical care, and gender equality. According to Jonathon Porrit, a British environmentalist and writer, “The combined population of the four countries [Ethiopia, Uganda, Somalia and Kenya] was 40 million in 1960. Now it is nearly 170 million [in late 2011].” “Overall, the human population has quadrupled in the twentieth century”(Cromwell 167) alone due to technological and medical advancements of the industrial revolution Because of the Industrial revolution, there have been many advancements in medicine, leading to lower morality rates in developed and developing countries alike. Developing countries lack the education and family planning that they need in order to maintain a stable and healthy population. Family planning is the act of” anticipate and attain their desired number of children and the spacing and timing of their births. It is achieved through use of contraceptive methods and the
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,
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 human population has been growing rapidly for centuries. What is happening and, most important, what will happen to all of us and our planet if this continues? One of the most important properties of living things is that their abundances change over time and space. This is as true for our own species as it is for all others, including those that directly or indirectly affect our lives. for example, when providing our food, or materials for our shelter, or causing diseases and other problems. It is safe to say that human populations, like that of the United States, grow at an exponential rate, which means that the annual growth rate is a constant percentage of the population. The danger that the human population poses to the environment
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
The expansion and development in all of the earth’s climate zones and habitats, as well as modern agriculture’s ability to grow more food for each unit of farmed land, play an important role in the population growth. Socioeconomic factors such as, healthcare, culture, family structure, marriage and social status also influences population growth, are contributors to population size increases through birth rate, as well as, decreases through the death rate. This imbalance of population equilibrium is a result of improved sanitation and health care, and the development of antibiotics and vaccines for the control of infectious diseases ultimately resulting in population death rates dropping.
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.
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
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 earth as we know it is spiraling towards extinction and the main enemy is overpopulation. Because of the increase in humans and their innate ability to destroy what its’ resources we could possibly lose our world as we know it. The balance in our living systems versus the population is not equal. We in America tend to live for right now, with little or no regard for our future. Can we change? What must we do to change? Let us
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
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.
