Human Population Growth Essay
No matter what organism you are talking intimately, all living things possess the ability to reproduce. This comes in two forms. The first form of community growth is Exponential Population Growth. The second is Logistic Population Growth. Exponential population growth refers to when a population is not subject to any hold factors, it will grow and expand exponentially even past the capacitor 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, & 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 sealsthe 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.
