With the increasing human population on Earth accompanied by an array of factors such as disease, lack of resources, and increasing life spans, it becomes dramatically harder to look into the future and predict that the world is not being overpopulated by humans. However, despite the myriad of overwhelming issues regarding the concern of overpopulation, I posit through several

point of succeeding in protecting the environment. One key element effecting the environment in Georgia is pollution. The population has grown past the means of Georgia’s expectation.

Population Growth and Ecological Footprints The population size (N) of a species at any point in time (t) is determined by its size at (t-1), its per capita birth rate (b), its per capita death rate (d), and immigration and emigration. Each of these values is, in turn, affected by a huge suite of biotic and abiotic conditions. Human populations are governed by these same variables. In this laboratory, you will use models of population growth to understand how population growth
