In biology, the carrying capacity of an environment is the number of organisms of a particular species that can live there without harming the environment. If too many organisms live in an environment, it is called overpopulation.
The carrying capacity of an environment can change, and humans can have an effect on the carrying capacity. For example, agriculture and irrigation allow feeding more people; meaning human carrying capacity is increased.
