Professor Emeritus of Cornell University David Pimentel remarks, “with the imbalance growing between population numbers and vital life sustaining resources, humans must actively conserve cropland, freshwater, energy, and biological resources…Humans everywhere must understand that rapid population growth damages the Earth’s resources and diminishes human well-being.” The term overpopulation refers to the human population exceeding the maximum population the Earth can sustain indefinitely, given habitat, water, food, and other necessities. It should be noted that overpopulation does not relate to population density or numeric size, but the ratio between humans and available resources. As an environmental issue, overpopulation is associated with topics like agricultural run-off, land use, habitat destruction, fragmentation, climate change, and disease prevalence. In this article, I will explore the last, and in my opinion, most significant issue surrounding overpopulation disease prevalence and transmission. A significant determinant of the quality of human life, disease transmission has affected the ecological relationship between human, microbes, and the environment. A relatively modern concern, overpopulation was not an acknowledged issue until the late 1880s, and was first addressed by the influential English scholar Thomas Malthus. Originating the idea of carrying capacity, the number of individuals in a given place that can be supported by their environment, Malthus believed the human population would eventually exceed carrying capacity and lead to a global catastrophe. Though not necessarily accurate in all his theories, overpopulation has been the culprit of many of the world’s emerging environmental issues. Having increased since the Bubonic Plague the world’s population reached 1 billion at the onset of the 19th century and as of 2011 has reached a
