Population Growth

Any reproducing organism population and its interaction with its offspring constitutes a Population Growth reinforcing loop. Population Growth is a Reinforcing Loop structure alternate to the Population Decline structure.

Population interacting with birth rate, which is considered to be a constant in this model, produces births. Births are then added to the population making it larger. This larger population will then interact with the birth rate adding even more births.

It should be evident that this is a very naive representation of a population growth cycle. There are numerous additional influences that come into play in any model of a real environment.

This Reinforcing Loop may be virtuous or viscous depending on whether the species multiplying are members of your immediate family or flesh eating bacteria. There is a difference!
