Overpopulation

Definition of overpopulation:

simple:

If the number of people living in an area is greater than the resources available to support the population then it is overpopulated

Overpopulation

  • Definition of overpopulation:

  • complex:

  • Overpopulation is not a function of the size or density of the population.

  • Overpopulation is determined using the ratio of population to available sustainable resources.

Overpopulation

If a given environment has a population of ten, but there is food or drinking water enough for only nine, then that environment is overpopulated; if the population is 100 individuals but there is enough food, shelter, and water for 200 for the indefinite future, then it is not.

Overpopulation

Overpopulation can result from an increase in births, a decline in mortality rates due to medical advances, from an increase in immigration, a decrease in emigration, or from an unsustainable biome and depletion of resources. It is possible for very sparsely-populated areas to be overpopulated, as the area in question may have a very meager or non-existent capability to sustain human life (e.g. the middle of the Sahara desert or Antarctica).
