Answer:

A population decline (sometimes underpopulation or depopulation) in humans is a reduction in a human population size caused by short term events such as pandemics, wars, famines or other catastrophes, or by long-term demographic trends, as in sub-replacement fertility rate, or persistent emigration

Explanation:

Overpopulation or overabundance occurs when a species' population becomes so excessive that people deem it must be managed. It can result from an increase in births (fertility rate), a decline in the mortality rate, an increase in immigration, or a depletion of resources
