When does overpopulation occur?

Overpopulation occurs when the birth rate exceeds the death rate. This imbalance leads to an increase in population numbers that surpasses the capacity of the environment to support that population sustainably. When more individuals are born than can be adequately supported by available resources such as food, water, and shelter, it can result in strain on those resources, environmental degradation, and various socio-economic issues.

The scenario where birth rates are higher than death rates creates a situation where the population continues to grow, leading to overpopulation. This concept is crucial in understanding human impact on the environment and the necessity for sustainable practices to ensure that population growth does not exceed the ecological carrying capacity.
