Human overpopulation (or human population overshoot) is the idea that human populations may become too large to be sustained by their environment or resources in the long term. The topic is usually discussed in the context of world population , though it may concern individual nations, regions, and cities.
The Global Footprint Network purports to be able to measure how much the human economy demands against what the Earth can renew. [13] [14] The Optimum Population Trust (now called Population Matters) has listed what they believe is the overshoot (overpopulation) of a number of countries, based on the above. [15]
Overpopulation or overabundance is a state in which the population of a species is larger than the carrying capacity of its environment.This may be caused by increased birth rates, lowered mortality rates, reduced predation or large scale migration, leading to an overabundant species and other animals in the ecosystem competing for food, space, and resources.

Overexploitation of these resources for protracted periods can deplete natural stocks to the point where they are unable to recover within a short time frame. Humans have always harvested food and other resources they need to survive. Human populations, historically, were small, and methods of collection were limited to small quantities.
Graph of human population from 10,000 BC to 2017 AD. It shows the extremely rapid growth in the world population since the eighteenth century. The Population Bomb was written at the suggestion of David Brower, the executive director of the environmentalist Sierra Club, and Ian Ballantine of Ballantine Books following various public appearances Ehrlich had made regarding population issues and ...
Population pressure, a term summarizing the stress brought about by an excessive population density and its consequences, is used both in conjunction with human overpopulation and with other animal populations that suffer from too many individuals per area (or volume in the case of aquatic organisms).
Environment destruction caused by humans is a global, ongoing problem. [4] Water pollution also cause problems to marine life. [5] Some scholars believe that the projected peak global population of roughly 9-10 billion people could live sustainably within the earth's ecosystems if humans worked to live sustainably within planetary boundaries.
