Sunlight's Fine-Tuned Spectrum
- The sun emits an extraordinary range of electromagnetic radiation, but only a tiny band is suitable for photosynthesis and life.
- It's amazing that the sun's output is finely tuned to produce mostly visual and infrared light allowing complex life to thrive.
Water Enables Warm-Blooded Life
- Water's unique thermal properties enable warm-blooded organisms to regulate body temperature efficiently.
- Its high evaporative cooling and low viscosity support circulatory systems essential for complex multicellular life.
Water's Role in Earth's Renewal
- Water facilitates plate tectonics and the recycling of Earth's crust essential for refreshing the planet's chemicals.
- Its cycle distributes life-giving water to land, sustaining terrestrial life forms like humans.
