The breath of Earth — 78% of the atmosphere is nitrogen. With every breath you draw it in, pure air in elemental form. And bound, that same substance sits in every protein, every strand of DNA.
Made in stellar CNO cycles in stars heavier than the Sun. Released to the cosmos when those stars die.
Lab note · 3% of your body, ≈1.8 kg. Every amino acid contains nitrogen — without it, no proteins, no enzymes, no thought.
