Five Essential Resources We Harvest from the Ocean

The ocean provides humanity's life support system. Five foundational resource categories:

1. Food — 170M+ tonnes/yr wild capture + aquaculture; 3.3B people rely on fish for 20%+ animal protein; seaweed (35M tonnes) rising.
2. Energy — Oil/gas (30% global production offshore); renewables: wind (fixed + floating), tidal, wave, OTEC, osmotic — vast untapped potential.
3. Minerals — Polymetallic nodules (Mn, Ni, Cu, Co), crusts, sulfides (Cu, Zn, Au, Ag) on seabed; rare earths in deep-sea mud. ISA regulates "Area" beyond jurisdiction.
4. Pharmaceuticals — 20+ marine-derived drugs approved (anticancer, antiviral, pain); 1,000+ candidates in pipeline; sponges, tunicates, microbes, cone snails — chemical novelty unmatched on land.
5. Tourism & Recreation — Coastal tourism = 5% global GDP; coral reefs alone $36B/yr; diving, cruising, fishing, wellness — "blue economy" pillar.

Emerging & Ecosystem Services

• Carbon sequestration (blue carbon: mangroves, seagrass, saltmarsh).
• Coastal protection (reefs, marshes buffer storms).
• Climate regulation (heat uptake, circulation).
• Genetic resources (bioprospecting, Nagoya Protocol).

Sustainable use requires recognizing the ocean as finite, interconnected, and indivisible from human survival.
