3. Hypothesis: that the entire mass of living matter on Earth (the biosphere) functions as a single and vast superorganism that actively modifies its planet to produce the environment that suits its needs.
Properly defined as "hospitality" as a full homeostasis (ability to self regulate the internal environment)

4. 4 factors that work together
Biosphere
Oceans
Atmosphere
Soil

5. 3 Ways Earth regulates itself
Surface Temperature – has remained constant despite the energy increase by the Sun
Atmospheric Composition – remains constant even though it should be unstable
Ocean Salinity – remains constant despite the fact that river salts should have raised the ocean salinity much higher

6. Daisyworld
Lovelock used this computer simulation to demonstrate the hypothesis
Hypothetical world orbiting a sun whose temperature is slowly increasing in the simulation
Planet has two different species of daisy as its only life form: black daisies and white daisies
