Detailed explanation-1: -Overpopulation is the state whereby the human population rises to an extent exceeding the carrying capacity of the ecological setting. In an overpopulated environment, the numbers of people might be more than the available essential materials for survival such as transport, water, shelter, food or social amenities.

Detailed explanation-2: -More people means an increased demand for food, water, housing, energy, healthcare, transportation, and more. And all that consumption contributes to ecological degradation, increased conflicts, and a higher risk of large-scale disasters like pandemics.

Detailed explanation-3: -One of the most common causes of overpopulation is the introduction of foreign species to a new ecological niche for which they have no natural predators. A famous example is the introduction of rabbits to Australia in the 19th century, where they had no natural predators.
