“The study of human characteristics of human populations” is known as demography which helps depict the progress of nations at many levels (Know, Marston, Imort and Nash, 2011, p. 99). Also it displays information that can relate to the current problems that the nations are facing. The advancement of populations is measured using the demographic transition theory which consists of four main phases, with unique characteristics that countries are grouped within. Studies conducted on these nations are significant as it helps us gain an understanding of the current position the country is in, and how it can develop into an industrialized nation.
According to the population explosion theory, after the start of the Industrial Revolution, the rate of population growth began to increase at an alarming speed. By the end of the century, the world's population was estimated at just under 1 billion. At the turn of the 20th century, the world's population was about 1.6 billion. By 1940, this figure had increased to 2.3 billion. Overpopulation issue has drawn a lot of c...
Overpopulation is a major global crisis because of a number of reasons. Most of the problems we have today, such as ocean depletion, water shortages, water pollution, food shortages, global warming, and air pollution are the effects of overpopulation. The more people there are, the more resources consumed and the more waste created. A child born today in the United States for instance will produce fifty-two tons of garbage and consume 11 million gallons of water by the age of seventy-five. Freshwater, drinkable water is the most critical natural resource to humans. As time goes by, the world’s population expands more rapidly, but there is no more freshwater on the Earth than there was two thousand years ago. Overpopulation has also increased industrial development, which contributes to massive urbanization and rising of living standards. The rising in living standards causes people to consume more, which creates more waste and raises life expectancy, which causes more people to live longer and more people to live in the same place, earth.
1. Briefly describe the factors that lead to population growth and potential stabilization. How does human demographics influence population dynamics in more and less developed nations and what might this mean for future population and economic growth? What do you see as the pros and cons of a large human population (brief)? Are there too many or too few people?
The world’s population increased by about 300 million as of A.D 1 and continued to increase at a moderate
The world’s population has been growing faster and faster, which projects potential problems with maintaining world food and water supply, and altering biodiversity worldwide. Fortunately, there are practical and manageable ways to keep the world’s human population in check to make sure that overpopulation is avoided. According to the population reference bureau the world population is reaching close to 7,200,000,000 people and increasing fast. The University of Washington estimated the world population to reach a massive 11 billion people by 2100; this was even increased from the U.N.’s prediction in 2011 of 10.1 billion. The current rate of population growth could have a crippling impact on the future welfare of the human and the natural world in this century. There are about 78 million more births than deaths each year; this is alarmingly fast, even with most women having 2 or fewer children. That’s equivalent to the entire population of Germany every year.
Population growth affects the earth just as much as it does the people. With the population continuously growing at an alarming rate, earth can’t keep up with the resources needed to survive. Eventually we will run out of oil, land to build houses, and air. The reasoning behind running out of air is if the world is covered in houses, there is no room for trees – which supplies our oxygen. The factors effecting population growth are: fertility rates, life expectancy, migration, and death rates. More and more people are migrating to North America because of the high life expectancy, average fertility rates, low mortality rates, and of course, job opportunity. Even though population growth isn’t as high as it used to be, overpopulation can still
In the eighteenth century, population growth in Europe skyrocketed. Until the 1700s the population was growing gradually at a rate of 0.5 to 1. However, due to famine, epidemic disease, and war in many years, prior to the 1700s, the birth rate was lower than the death rate. The rapid population increase had several different causes; the most influential causes were that more babies were being born, sanitation of water and sewage were better cared for, and less people were.
There are various systems in handling population rates and its various issues that connect with threatening our environment. The population and environment debate will forever be a back and forth problem because there is possibly no way to completely stop carbon emissions but ease its production. To help the environment, we must incorporate all potential solutions in governing population such as family planning and governmental involvement and practice renewable resources and stop on using nonrenewable resources, as well as ways to tackle overconsumption to support our corrupting environment.
Population Growth, Industrialization, and the Environment
Human population growth was relatively slow for most of human history. Within the past 500 years, however, the advances made in the industrial, transportation, economic, medical, and agricultural revolutions have helped foster an exponential, "J-shaped" rise in human population (Southwick, Figure 15.1, p. 160). The statistics associated with this type of growth are particularly striking: "Human beings took more than 3 million years to reach a population of 1 billion people... The second billion came in only 130 years, the third billion in 30 years, the fourth billion in 15 years, the fifth billion in 12 years..." (Southwick, p. 159).
