Types of overpopulation - People overpopulation

People overpopulation refers to a situation where there are more people than the supplies of food, water and other vital resources i.e. population growth exceeds the rate of economic growth and people are too poor to grow sufficient food or buy essential commodities. In this type of overpopulation the size of population and the resulting degradation of potentially renewable resources such as soil, grassland, forests, and fisheries tend to be more important in determining the total environmental impact.

In the world's poorest less developed countries people overpopulation results in the premature death of 12-20 million human beings per year due to hunger and nutrition stress and famine induced diseases. Some regions are, stressed by overpopulation, overgrazing, severe soil erosion-are reducing the land's productivity. Thus many subsistence farmers and nomads are losing their means of livelihood and source of food.
