Human Population Growth
Humans have occupied and survived most conditions on Earth. Humans have expanded to all regions on Earth and continue to survive comfortably in most areas. In fact, some areas have become unsuitable for living due to the overwhelming population of humans and their impact on the environment. However, in some areas on Earth human population is dwindling due to the environment. This paper will discuss human population and the environmental impact of human population on Earth.
You have already read that humans populate many areas on Earth, but how is human population information sorted? Ecologists have created two mathematical models to determine human population, environmental impact of humans in an area, as well as the impact subjected to humans by the environment. The Exponential population growth model is used to determine what population growth would be like in an unlimited environment. “Exponential population growth describes the expansion of a population in an ideal, unlimited environment” (Simon, E. J., Reece, J. B., & Dickey, J. L., 2010). This would mean that the model doesn’t reflect environmental impacts such as disease, catastrophes, or the exhaustion of resources in an environment. However, the Logistic population growth model does reflect environmental factors such as those described. “In logistic population growth, the growth rate decreases as the population size approaches carrying capacity” (Simon, E. J., Reece, J. B., & Dickey, J. L., 2010).
Now that we’ve covered the two types of population growth, we can determine what type of growth humans exhibit. Exponential growth is the category that humans fall under due to the steady population growth throughout the years. The death rate for humans is much lower than birth rate due to the innovation of technology in the medical field coupled with better understanding of the human body.
According to Simon (2010), “the human population is expected to continue increasing for at least the next several decades”. This means that human population will incline for several more…
