The Gaia hypothesis ( / ˈɡaɪ.ə / ), also known as the Gaia theory, Gaia paradigm, or the Gaia principle, proposes that living organisms interact with their inorganic surroundings on Earth to form a synergistic and self-regulating, complex system that helps to maintain and perpetuate the conditions for life on the planet.

James Lovelock called his first proposal the Gaia hypothesis. but the term established nowadays is Gaia theory. Lovelock explains that the initial formulation was based on observation, but still lacked a scientific explanation.

Gaia hypothesis
Gaia hypothesis, model of the Earth in which its living and nonliving parts are viewed as a complex interacting system that can be thought of as a single organism. Developed c. 1972 largely by British chemist James E. Lovelock and U.S. biologist Lynn Margulis, the Gaia hypothesis is named for the Greek Earth goddess. It postulates that all living things have a regulatory effect on the Earth ...
Gaia Hypothesis
The Gaia hypothesis postulates that the Earth's surface is maintained in a habitable state by self-regulating feedback mechanisms involving organisms tightly coupled to their environment. The concept is based on several observations: • The atmosphere is in an extreme state of thermodynamic disequilibrium owing to the activities of life, yet aspects of its composition are remarkably stable.
Gaia Hypothesis
Gaia Hypothesis Introduction. The term Gaia hypothesis is based on the Greek word meaning land or earth, and the name of the Greek goddess. The Gaia hypothesis contends that all constituents of Earth, living and nonliving, are part of an interconnected system (the biosphere), and that every living thing can affect Earth's environment.
Climate
Lovelock called his idea the " Gaia Hypothesis " and defined Gaia as. a complex entity involving Earth's biosphere, atmosphere, oceans, and soil; the totality constituting a feedback of cybernetic systems which seeks an optimal physical and chemical environment for life on this planet. The Greek word Gaia, or Gaea, meaning "Mother Earth ...

He may compare it with the cycling of water from the oceans to the land.
Gaia hypothesis
The Gaia hypothesis states that the mean global temperature, the composition of reactive gases in the atmosphere, and the salinity and alkalinity of the oceans all are actively regulated and modulated by the biota (flora, fauna and microbiota) at a planetary level. The chemical reactions of a physiological system, unlike those of a physical ...
Gaia philosophy
Gaia philosophy (named after Gaia, Greek goddess of the Earth) is a broadly inclusive term for relating concepts about, humanity as an effect of the life of this planet.. The Gaia hypothesis holds that all organisms on a life-giving planet regulate the biosphere in such a way as to promote its habitability. Gaia concepts draw a connection between the survivability of a species (hence its ...

Gaia Hypothesis
The Gaia hypothesis is an ecological hypothesis proposing that the biosphere and the physical components of the Earth (atmosphere, cryosphere, hydrosphere and lithosphere) are closely integrated to form a complex interacting system that maintains the climatic and biogeochemical conditions on Earth in a preferred homeostasis. Originally proposed by James Lovelock as the earth feedback ...

Updated 9/30/2017. format for printing. "The Gaia hypothesis says that the temperature, oxidation state, acidity, and certain aspects of the rocks and waters are kept constant, and that this homeostasis is maintained by active feedback processes operated automatically and unconsciously by the biota." - James Lovelock, The Ages of Gaia.
Gaia Hypothesis
Gaia hypothesis. The Gaia (pronounced GAY-ah) hypothesis is the idea that Earth is a living organism and can regulate its own environment. This idea argues that Earth is able to maintain conditions that are favorable for life to survive on it, and that it is the living things on Earth that give the planet this ability.

Daisyworld is a computer model designed to help prove the Gaia hypothesis.

The Daisyworld model shows, for example, how a planet's inhabitants can work to stabilize its temperature, even as the intensity of its ...

The Gaia Hypothesis in Action: Homeostasis and Feedback Mechanisms. A fundamental principle of the Gaia hypothesis is the presence of homeostasis, a state of equilibrium that allows the planet to maintain stable conditions conducive to life. Feedback mechanisms, both positive and negative, play a crucial role in regulating Earth's systems.
