  2. Sustainable population - Wikipedia

    en.wikipedia.org/wiki/Sustainable_population

    Many studies have tried to estimate the world's sustainable population for humans, that is, the maximum population the world can host. [5] 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 9.8 billion people, respectively.

  3. Human overpopulation - Wikipedia

    en.wikipedia.org/wiki/Human_overpopulation

    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.

  4. Carrying capacity - Wikipedia

    en.wikipedia.org/wiki/Carrying_capacity

    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]

  9. Human population projections - Wikipedia

    en.wikipedia.org/wiki/Human_population_projections

    Human population projections are attempts to extrapolate how human populations will change in the future. [1] These projections are an important input to forecasts of the population's impact on this planet and humanity's future well-being. [2] Models of population growth take trends in human development and apply projections into the future. [3]
