Foreword
Overpopulation takes place when the population of a living species exceeds the carrying capacity of its environmental place. In general dialect, this word usually refers to the relationship between the human population, its environment, and Earth.
Overpopulation is not a purpose of the figure or density of the persons, but somewhat the number of individuals compared to the resources they need to survive. Hence, it is a ratio of population over resources. If a certain environment has a population of 10, but there is food and drinking water enough for only 9 people, then that environment is overpopulated, whereas if the population is 100 persons but there are food and water sufficient for 200, then it is not overpopulated.
Overpopulation can result from increases in births, a rejection in humanity rates, which is related to increases in life expectancy, or from an invalid use and exhaustion of resources. Advances in technology can reduce the threat of overpopulation by making new resources obtainable, or by increasing the output of existing resources. Resources should be taken into account when estimating if an environmental position is overpopulated include clean water and air, food, shelter, warmth, or other issues related to endurance. In human beings, there are others for example arable land and, for all but tribes with archaic lifestyles, lesser resources for example employment, money or other economic resources, education, fuel, electrical energy, healthcare, proper sewage management and waste management, and transportation.
In the environment of human civilizations, overpopulation takes place when the population density is so huge as to in fact cause an impaired quality of life, environmental degradation, or long-term shortages of vital goods and services. Overpopulation is not just an imbalance among the number of persons compared to the resources they need to survive, or a relation of population over resources......................
