Why the Ocean Is Essential to All Life

1. Oxygen production: Phytoplankton generate >50 % of Earth’s O₂.
2. Climate regulation: Absorbs and redistributes solar heat.
3. Food supply: Fish and seafood feed billions.
4. Energy source: Wave, tidal, and current power.
5. Transportation: Global shipping lanes.
6. Biodiversity: Over 1 million known marine species; likely millions more undiscovered.

Protecting the ocean is critical for planetary health.
