[00:00:00]What if I told you that coral reefs are actually keeping a coded diary of Earth's secrets? Each year, corals add a new ring to their skeletons, just like trees do.

[00:00:10]But these rings aren't just pretty patterns. They're full of hidden clues.

Scientists can read these rings to uncover lost chapters of our planet's history. Next time you see a coral, remember, it's not just alive. It's quietly writing the story of our world, one hidden message at a time.
