Two Categories of Ocean Dangers

Natural Hazards

• Severe storms (hurricanes, cyclones, typhoons)
• Earthquakes & tsunamis
• Volcanic eruptions
• Coral bleaching (from warming, pollution, overfishing)

Human-Caused Hazards

• Pollution (sewage, fertilizers, chemicals)
• Oil spills
• Overfishing
• Climate change (warming, acidification)

Both categories threaten marine life and coastal communities.
