The two great economic revolutions that marked human history up to 1900—the agricultural and industrial revolutions—greatly increased the Earth's human carrying capacity, allowing human population to grow from 5 to 10 million people in 10,000 BCE to 1.5 billion in 1900. [44]
Attempts have been made to estimate the world's carrying capacity for humans; the maximum population the world can host. [131] A 2004 meta-analysis of 69 such studies from 1694 until 2001 found the average predicted maximum number of people the Earth would ever have was 7.7 billion people, with lower and upper meta-bounds at 0.65 and 98 billion ...
An expanding population can be considered as an increase of available human capacity for increasing food production. [37] The static aspect of the Malthusian hypothesis, which is based on the rule of decreasing returns, [38] limits its applicability.
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.
The 1972 book The Limits to Growth discussed the limits to growth of society as a whole. This book included a computer-based model which predicted that the Earth would reach a carrying capacity of ten to fourteen billion people after some two hundred years, after which the human population would collapse.

Harm's Way promoted the album with music videos for "Become a Machine" [7] and "Last Man", [8] and online streams of "Human Carrying Capacity" and "Call My Name". [9] Critics generally gave Posthuman favorable reviews, with several reviewers noticing an increased emphasis on industrial metal and nu metal over previous releases.
The maximum endurable impact is called the carrying capacity. As long as "I" is less than the carrying capacity the associated population, affluence, and technology that make up "I" can be perpetually endured. If "I" exceeds the carrying capacity, then the system is said to be in overshoot, which may only be a temporary state. Overshoot may ...
