Human Population Growth Factors
The growth in human population has been steadily increasing throughout most of history, but in the last 200 years it has escalated rapidly. There are numerous factors which account for the growth in human population, however those with the greatest influence include fertility and mortality rates, demographics, production of food, diseases and medical advances, economics, to name but a few. In the United States, the population has also expanded, growing from "76 million in 1900 to 304 million in 2008," with one of the largest increases coming in the years 1946 to 1964. (Miller, 2008, p.82) Although the rate of population growth has decreased since 1964, the population of the United States is still growing at a faster rate than any other industrialized nation. And while it is true that as a nation becomes more industrialized its rate of population growth decreases, the growth in population in the U.S. over the next fifty years can potentially lead to many social, economic, and political problems.

The fertility rate can be considered to be the rate at which babies are born in a specific population, while the mortality rate is the rate at which people die. A number of factors can have an influence that rate, specifically the availability of food, for instance, has a direct affect on the fertility and mortality rate; and food production depends upon other factors such as climate and technology. These rates can also be affected by economic factors such the economic resources of parents, the availability of advanced medical care, education and employment opportunities, as well as urbanization and the availability of abortion services. With economic wealth comes better medical care, including preventative medicine, more and better nutritional intake, and the a greater likely an infant will survive childbirth and live a healthier and longer life.
At the current rate of growth the population of the United States will increase to nearly 400 million. ("U.S. Population Growth")…
The modern separation from the means of production does not negate the fact that nearly everything we need to sustain us is provided by the earth, either by natural or artificial means. The earth gives us all the materials we need and many we desire and in turn she is changed. She becomes less able with each passing day and each lost natural acre to continue to provide. Though the
At a most simplistic level, the growth of the human population generates higher levels of consumerism. And the higher levels of consumption place supplementary strains on the already scarce natural resources. Additionally, the incremental levels of consumption translate into higher levels of waste. This waste comes from both individual consumers, as well as from industrial agents and it directly impacts the quality of the water as well as the
Human Population There are two primary biological mechanisms that determine the growth and suspension of species: natality (birth) on the one hand, and mortality (death), on the other. Amongst humans, other factors may intervene in their natality factor and these include economics, migration, physical upkeep, and social forces of various sorts (Pearl, (1927). This is due to the fact that humans have a rational capacity that other organisms lack, hence humans
Communities that understand the toll population growth has on the environment are more likely to take action to protect the environment and conserve natural resources by monitoring population growth and encouraging restoration of the environment rather than encouraging larger families (Mulligan, 2006). Community actions are more likely to be tolerated than mandates that declare population growth must be limited by force (Mulligan, 2006). Evaluate Effects of Human Activities on Ecosystems
Omole-Ohonsi, (2007) in his study of sub-Saharan Africa confirmed these affects by suggesting that overpopulation of a locality not only damages the environment and sustainability but "feeds the cycle of poverty" (20). Thus, from non-renewable resources to social problems, the effects of overpopulation are large and far-reaching, encouraging a cycle of environmental destruction and poverty. Ways to Achieve Sustainability As previously mentioned, overpopulation is a difficult problem to solve because it deals
Human Population in El Paso Population Explosion in El Paso and Juarez Globalization is well in full force. The increasing population explosions in El Paso and Juarez Mexico show that international business and economic developments are encouraging people from the interior of Mexico to flood into border towns and eventually into the United States. What has resulted, however, is chaos partly because the two towns do not have proper legislation or budgeting
