Overpopulation

Human overpopulation  refers to a human population that is too large to be sustained by its environment in the long term. The idea is usually discussed in the context of world population, though it may also concern regions. Human population growth has in recent centuries become exponential due to changes in technology that reduce mortality. Experts concerned by this trend argue that it results in a level of resource consumption which exceeds the environment's carrying capacity, leading to population overshoot. The subject is often discussed in relation to other population concerns such as demographic push, depopulation, ecological or social collapse  and human extinction.
