According to the World Population Data sheet, there will be about eight billion people by the year 2020, and this is due to its continuation of growth (Southwick 159). A clear understanding of the causes and what might possibly happen is the first step to dealing with the population crisis. The world s human population has been growing in what has been described as a j-shaped curve. In the early 1900 s, the world s population numbered nearly two billion; it has more than tripled since then (Southwick 159). There are three theories or models for population growth. The Malthusian theory predicts that human misery and eventual catastrophe will be the limiting factors for world population. Logistic theory predicts that there will be some sort of gradual resolution as humans adapt and are able to support a population between eight and ten billion. The domed model of growth predicts that between eight and ten billion will signal overpopulation, so a readjustment of to lower levels would be attained (Southwick 159). These three theories are important because each has different implications for the environment. Most ecologists consider human population growth to be one of the most pressing problems contributing to environmental degradation.
