Episode notes
Gaia Hypothesis
- The Gaia Hypothesis proposes that Earth is a self-sustaining, living entity.
- This idea, though initially ridiculed, is being reconsidered by some scientists.
Life as Earth's Extension
- Ferris Jabr argues that life is an extension of Earth, not separate from it.
- Life is made of Earth's materials, just like sandcastles are made of sand.

- Life acts as Earth's anatomy and physiology, enabling energy absorption and gas exchange.
- This is similar to how organisms' cells function, although Earth's system formed differently.
