Carrying Capacity - Humans

Humans

Several estimates of the carrying capacity have been made with a wide range of population numbers. A 2001 UN report said that two-thirds of the estimates fall in the range of 4 billion to 16 billion (with unspecified standard errors), with a median of about 10 billion. More recent estimates are much lower, particularly if resource depletion is considered.

The application of the concept of carrying capacity for the human population has been criticized for not successfully capturing the multi-layered processes between humans and the environment, which have a nature of fluidity and non-equilibrium, and that it often has a blame-the-victim framework.

Supporters of the concept argue that the idea of a finite carrying capacity is just as valid when applied to humans as when applied to any other species. Animal population size, living standards, and resource depletion vary, but the concept of carrying capacity still applies. The carrying capacity of Earth has been studied by computer simulation models like World3.

Famous quotes containing the word humans:

    To not be afraid in our world is the message that doesn’t derive from reason, but maybe from this mysterious capacity given to humans which we call—not without a little embarrassment—faith.
    Friedrich Dürrenmatt (1921–1990)

    Here we also see: what this divinity lacks is not only a sense of shame—and there are also other reasons for conjecturing that in several respects all of the gods could learn from us humans. We humans are—more humane.
    Friedrich Nietzsche (1844–1900)

    The difference between humans and wild animals is that humans pray before they commit murder.
    Friedrich Dürrenmatt (1921–1990)
