<human>:  How does James Lovelock’s The Gaia Hypothesis work?
<bot>: The Gaia Hypothesis is a hypothesis that the Earth is a self-regulating system. It was proposed by the British scientist James Lovelock in the 1970s. Lovelock's hypothesis is that the Earth functions as a single organism, which maintains homeostasis through a complex chemical and physical interaction between the atmosphere, hydrosphere, and lithosphere.
