1. April 2012 TEN THREATS TO OCEAN HEALTH

2. GLOBAL CLIMATE CHANGE Sea levels rise Temperature rises Storms, floods, weather Current patterns Coral bleaching

3. Caused by increasing man-made carbon dioxide emissions Makes the ocean more acidic Changes the chemistry of the sea and is harmful for many forms of marine life OCEAN ACIDIFICATION & CLIMATE CHANGE

4. Swaths of ocean that don't support life due to a lack of oxygen Growing at an alarming rate Over 400 known to exist Thought to be caused by global climate change and fertilizer/pesticide runoff DEAD ZONES

5. Over 80% of marine pollution comes from land-based activities Oil Spills Production waste Marine Debris GPGP Shipping POLLUTION

6. When the amount of fish caught is more than the amount of fish needed to sustain fish stocks in a given region Disrupts the food chain Bycatch – unintentional captures OVERFISHING

7. Supposed to respond to overfishing Poorly managed operations Nutrient and chemical pollution released into environment Accidental release of farmed fish is also damaging Unregulated IRRESPONSIBLE FISH FARMING

8. From: Illegal Aquarium trade Irresponsible aquarium owners Release of foreign bait Traveling Ships Displace native species Diminishes biodiversity INVASIVE SPECIES

9. Offshore drilling Chemicals like mercury, arsenic, and lead also come up with the oil Seismic waves used harm marine life Infrastructure erodes coastline Mangrove destruction Habitat loss 25% of all species may be extinct by 2050 Tourism RESOURCE EXTRACTION & COASTAL DEVELOPMENT

10. Affects everything 50-100 million killed each year Bycatch Hunted When finned sharks are thrown back still alive and bleed to death They reproduce too slowly for populations to recover SHARK FINNING/WHALING

11. Coal plants Ends up in the food we eat Already contaminated water in all 50 states Biomagnification Tuna MERCURY POISONING
