5. Impacts: Natural Environment Session 7: Coastal Hazards II Coastal Hazards Management Course Slide 7. 4, Environmental Impacts (Courtesy: John Bruno) Natural disturbances from hazards have an effect on coastal ecosystems such as coral reefs and seagrass

6. Session 7: Coastal Hazards II Coastal Hazards Management Course Slide 7. 5, Human Impacts (Courtesy: John Bruno) Sandy beach/barrier island development Impacts: Human Environment Disasters occur when the human built environment meets natural hazards

7. Disasters: Hurricanes Session 7: Coastal Hazards II Coastal Hazards Management Course Slide 7. 6, Human Impacts due to Hurricanes (Courtesy: FEMA) (Courtesy: NOAA Photo Library) On average, hurricanes kill 80 people per year in the US and Hurricane Andrew alone caused more than $25 billion in damages
