What does overpopulating mean?
Overpopulating means causing a place, species, market, or other system to contain more people or entities than it can adequately support. The term is especially common in discussions of population density, urban planning, environmental pressure, and public services. Overpopulating an area may strain housing, transportation, food, water, healthcare, and other resources, while overpopulating a habitat can cause competition for food and disruption of the ecosystem. It can also describe markets crowded with products, users, or businesses, though this use is less common. The word combines the prefix over-, meaning excessively or beyond a normal limit, with populate, meaning to furnish with people or inhabitants. The gerund form overpopulating is frequent in formal reporting, environmental writing, and commentary on population trends.
verbTo cause a population to become too large for the available resources or space. It can also mean to fill an area, system, or market with more people or entities than it can reasonably support.

Where does overpopulating come from?
The word is formed from the prefix over-, meaning excessively or beyond a normal amount, and populate, from Latin populare, meaning to fill with people. The related noun population derives from the same Latin root through French, and popular and populace also reflect that ancestry. Over- has been used with verbs since Middle English to indicate excess, as in overeat and overpower.
