Cómo hacer una concha marina - ¡Sólo añade agua!

The video explores the magical process by which ocean creatures like algae and snails create shells using calcium and carbonate from seawater. It explains how calcium carbonate forms more easily near the surface but dissolves at greater depths. The video also discusses the role of atmospheric gases, particularly carbon dioxide, in affecting ocean chemistry and shell formation. Feedback loops help stabilize ocean chemistry, but excessive carbon dioxide can disrupt this balance, potentially leading to a barren ocean environment.
