Definition of Exponential Population Growth

The population of the Earth has grown dramatically over the centuries, but it has usually been kept in check. If it were not, the population could expand exponentially.

Definition

Exponential population growth is when the birth rate is constant over a period of time and isn't limited by food or disease.

Significance

If this growth were to occur for too long, the species would eventually begin to die off as food and other resources became too scarce to support their numbers.

Effects

A species growing exponentially would also affect other species directly due to competition for food and other resources.

Considerations

If humans continue to reproduce at the current rate, Earth's capacity for the species could be reached, or possibly exceeded.

Reasons for Exponential Growth

Exponential growth can be affected by modern medicine, quality and quantity of food and the overall standard of living for a species.
