All over the world, the human population fluctuates throughout each country due to several different factors. Some of the factors that can lead to an increase or decrease in population include industrialization, economic instability, poverty, laws, disease, resource destruction, sanitation, natural disasters, birth control, and access to education (Class notes). Although population decline is possible and relevant in some countries, the more important issue facing many countries today is overpopulation. Some over population problems include decreases in food sources, housing needs, land, increase in distribution problems, decrease in job availability, and poor health care environment (HowMany.org, 2014). One important question related to controlling
Overpopulation, pollution, global warming, climate change, genetic modification, ocean acidification, water/soil pollution, deforestation, acid rain, and ozone depletion are among some of the main factors that have a negative impact on the planet. Overpopulation is one the most concerning environmental issues currently. Overpopulation is defined as the human population of a specific area exceeding the carrying capacity. Overpopulation can occur from an increase in births mainly or a decline in deaths. Also, other factors that affect overpopulation can be an increase in immigration or a depletion of resources. It was stated by the United Nations that the worth has a total carrying capacity of somewhere between 4 and 16 billion. Currently we hold over 7 billion humans on Earth. As of 2017 the UN has increased their population predictions to 9.8 billion by 2050 and up to 15 billion by 2100. Pollution we hear about every day.

Growing advances in technology with each coming year has affected humanity in many ways. Technology has given us the ability to save lives and create better medical treatment for all. A direct result of this has been increased lifespan and the growth of the population. In the past fifty or so years, the growth of population has increased rapidly and has turned into overpopulation. Developing countries face the problem of overpopulation more than developed countries, but it affects most of the Earth as of now. World population growth is causing many alarming problems. The population will continue growing in some parts of the world whilst others stabilize, with some estimates putting the final population of the world as high as 12 billion.
The topic of overpopulation has different perspectives regarding whether or not it is happening as well as its apparent effects of both the environment and its inhabitants. The idea of human overpopulation being a problem most clearly begins around the time of Thomas Robert Malthus’ publishing of An Essay on the Principle of Population as It Affects the Future Improvement of Society, with Remarks on the Speculations of Mr. Godwin, M. Condorcet, and Other Writers. In his writing, Malthus describes how the growth of the human population will always outgrow the resources required to maintain it. “The increase of population will take place, if unchecked, in a geometric progression, while the means of subsistence will increase in only an
Population Growth is an issue that exists in today’s world that needs to be confronted before it becomes out of hand. The population itself has reached overwhelming numbers making it a problem that could turn to be dangerous. The amount of humans that the earth can support or the carrying capacity is slowly rising but at a much slower rate than the population growth rate. The increasing growth rate has its negative effects environmentally, agriculturally, socially, and economically and also has its positive effects nationally, and economically. The government is brainstorming and trying to come up with ways to decrease
Thesis: The topic of human population growth is an important issue due to its impacts upon people in developing countries, economics, religion, food production, and the environment; without any limitations, population growth can lead to negative consequences, such as famine and environmental destruction, or even positive outcomes, such as potential economic growth.
As the human race continues to grow older the population starts to grow. Population growth is a change in the size of a population over time, depending on the balance of births and deaths over a period of time. For the world, population grows when the amount of births exceeds the amount of deaths. As shown in figure 1, the world’s population grew very slowly until about 1750 that is when the population growth started to increase rapidly. Figure 2 shows the growth of the global population from 1950 onwards, it also shows the projected population growth up to 2050. The global population is estimated to rise to approximately 9 billion people by 2050.
In recent years, Earth’s issues have become increasingly politicized, publicized, and economically important. When you examine how the environment affects us and how we affect it, it’s easy to see that overpopulation is one of earths most pressing environmental issues.
growth rate in the United States is approximately 2.2%. This means by 2050 the population could reach 438 million people (“World Bank Group”) Many citizens do not see any danger of the population rise in the United States. Unawareness might be the biggest factor in why they believe this; however, overpopulation can destroy the environment, including food and water sources, while also raising unemployment rates and the risk of disease.
While it may be observed that the exponential rate of growth is slowing, the world population is still growing rapidly. Perhaps the biggest concern is not the actual population increase but the distribution of the growth (Wilson, Population).
There are many articles and newspapers about how bad the world is becoming overpopulated. The overpopulation of humans and animals is a constant threat to people way of life on earth. Monbiot states, “The growth in human numbers, they say, is our foremost environmental threat” (Monbiot 1). Suggestions for extending women’s reproductive choices should be made, and the world population would drop dramatically because of this. George states, “If this need were answered, the impact of population growth would be significant, though not decisive: the annual growth rate of 83 million would be reduced to 62 million” (Monbiot 1). Because the population of the world is increasing drastically, many problems are created and produces many effects.
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.
In 1810, the world’s population was 1 billion; 200 years later, it is over 7 billion. What caused this tremendous jump in population growth? Better healthcare caused death rates to plummet, and caused successful birthrates to soar. Population growth rate is calculated with a simple formula (Birth rate – Death rate = Growth rate). The human population increases by about 80 million per year; and that number is actually increasing steadily. In another 140 years, the population could be close to 27 billion.
