Causes of Overpopulation Essay

The world population of 7.2 billion in mid-2013 is projected to increase by almost one billion people within the next twelve years. It is projected to reach 8.1 billion in 2025, and to further increase to 9.6 billion in 2050 and 10.9 billion by 2100. This assumes a decline of fertility for countries where large families are still prevalent as well as a slight increase of fertility in several countries with fewer than two children per woman on average.

The human population rate has changed throughout the ages. By looking at the table we were given the human population has increased heaps from 2000 years ago. If we look at our ancestors they lived with a small existence but this has changed as we have developed and there is more agriculture in this world. Population grew very slowly in the 1000 A.D. also decreased after the Black Death causing large numbers of people wiped out. Then in the 1800 A.D. the industrial revolution came, soon living standards were raised and there was food shortage with the population. In 1927 medicine was introduced this meant that there was increased life expectancy, so the human population grew more. There was more advantages from agriculture, medicine and sanitation

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.

There are more than seven billion people on Earth now, and about one in eight of us don’t have enough food to eat. So, with a projected nine billion people by the year 2050, how many people can the Earth support while maintaining a healthy population? Population changes are due to the relationship between births and deaths. If the number of births equals the number of deaths then the world’s population will remain the same, but if births exceed deaths, population growth will occur. Early in history, population was slowly growing because of high death rates related to wars, famines, and poor medical services. With advances in

Compare predictions for human population growth in developed countries versus developing countries. Why is it difficult to predict the growth of Earth’s human population? Why should population growth be predicted?”? What will happen if there is exponential human 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.

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.

In some poor countries, people usually have lots of children in an individual family, and the children can cost a lot of money, due to education, medicine, and nutrition. The family don't have enough money or resources to pay for their children, and then the children can easily become criminals and cause social problems. Overpopulation in a city or a country can cause the people to be unable to find a job and end up unemployed. In the nineteenth or early twentieth century in Europe, people who can not find a good job, went to their colonies such as, America and Asia. Nowadays, the people who are in the poor country can only go to the city. Then huge numbers of people come to the city, and everyone need food, water, and a place that they can live. The needs of the city growing rapidly. However, the natural resources are limited in some countries like China, India, and Pakistan and they do not have enough high-quality resources to support their vast population. As people are using more natural resources, they are also increasing the emission of the pollution. These caused the environmental burden. And the environmental problem is related with the population increasing. As long as the population increases, greater environmental challenges are to

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).

In the world today we have became to known of the upcoming problem;its not only been a problem in the U.S but other counties as well. Today’s population consist of 7,362,302,944 people world wide.Although, growing in population is consistently is a bad thing but it can be a good thing.

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 the late eighteenth century, Reverend Thomas Robert Malthus described how human population, when unchecked, grows exponentially while resources (specifically food) exhibits arithmetical growth (Moseley, Perramond, Hapkie, & Laris, 2014). Malthus primarily blamed the poor for high fertility rates and argued for the abolishment of all welfare, believing that if the poor succumbed to the negative effects of poverty, overpopulation could be stopped. While this may seem a distasteful solution to modern environmentalists, one cannot completely erase population from the environmentalist equation. Despite the technological advances that rendered much of Malthus' musings passé, one cannot ignore the idea that the carrying capacity of earth loom unknown

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.

Since 1914, global population has increased dramatically. Before 1914, there had been about 90 billion people ever born. Since then, the approximate number of people ever born has increased to 100 billion. Life was very short for the first 90 billion people and until World War I, the death rates and birth rates were neck to neck. Eberstadt (2014) believes that the number of humans born over the course of 50,000 years before the 1900’s could not have possibly grown by more than three one hundredths of one percent on average per century. The recurrent disappearance of nations and sometimes even entire civilizations enforced “population balance” for most of history. Around 1900, the human population was at around 1.5 billion and over the course

One of the problems facing our world is population. It began about ten thousand years ago when the humans settled and began farming. The farming provides more food for the people thus making the population grow. Now we are about 6 billion in population and in a few years we will be around 10 to 11 billion. Therefore, our population will
