3. Renewable Energy: Offshore wind, wave, tidal, and ocean thermal energy conversion (OTEC) offer clean power.
4. Recreation & Tourism: Coastal tourism is a massive economic sector; diving, sailing, beachgoing support wellbeing.
5. Climate Regulation: Absorbs ~25% of CO₂ emissions and >90% of excess heat; drives weather patterns via currents.
