Human Population Growth

Human Growth Population
Despite what organism a person discusses, all living things possess the ability to reproduce. This comes in two forms. The first form of population growth is Exponential Population Growth. The second is Logistic Population Growth. Exponential population growth refers to when a population is not subject to any limiting factors, it grows and expands exponentially even past the capacity of the environment to sustain. Rabbits are a good example of this form of population growth, “Thus, the exponential growth model explains how a few dozen rabbits can multiply into millions and overrun a continent.” (Simon, Reece, and Dickey, 2010).

Logistic population growth refers to when a population reaches the capacity of the environment to sustain, the population growth declines. Fur seals of St. Paul Island are a good example of this, “After hunting was controlled, the population increased rapidly until about 1935, when it began to level off and started fluctuating around a population size of about 10,000 bull seals—the carrying capacity for St. Paul Island.” (Simon, Reece, & Dickey, 2010) Humans tend to exhibit exponential forms of population growth. We rapidly reproduce and expand, exceeding the carrying capacity of the environment. This leads to us spreading to other areas and exceeding the carrying capacity there as well.



The scientist that have studied this curve also call this the “S-curve” because it has a strong resemblance to a large capital S when plotted correctly. The population growth rate of humans does have a significance effect on our population. The more people brought into this world the stronger the demand for other resources. The demand for food, shelter, and water will increase, as well as the need for education. Our forest and preserves are at risk due to the sudden need for more housing and land to build to meet the demand for growth. The more land that humans destroy to meet these needs the higher chances they...
