Which risk predominantly accelerates when coastal kelp forest degrades?

💡 Explanation

Coastal kelp degradation reduces wave energy dissipation near the shore; this exposes sediment to wave action. Wave refraction focuses energy at headlands causing increased Hydrodynamic erosion, because reduced kelp cover decreases drag. Therefore, coastal erosion increases, rather than nutrient changes or pH changes.
