The Disappearing Coral Reef Julie Smith 2008

Healthy Reef : biodiversity, brightly colored healthy coral Dead/Dying Reef : coral bleaching, limited flora and fauna

Carysfort Reef

So, Why Are Reefs Important Densest and most varied ecosystem on Earth Rain Forest of the ocean Home to 25% of all marine life Beginning of the marine food chain Coral Reefs cover only 0.07% - 0.2% of ocean floor

And the Problem Is? 27% have been lost 60% are at serious risk 32% could be lost in next 20 years It’s predicted that in as little as 50 years ALL coral reefs could be dead

Natural Coral Reefs of Florida

Environmental Risk to Natural Reefs

Coral Bleaching

What’s Killing the Coral Natural Stressors Diseases Black Band White Band White Plague Aspergillosis Predators Diadema (urchins) COTs (starfish) Drupella (snail) Weather Events

Localized Anthropogenic Stressors Boating Fishing Overfishing Poisoning/Bombing Collecting Tropical Fish Coral Mining Diving Devastation of Mangrove Forests (That’s things we do)

Global Stressors Silting Fertilizer Run-off Effluent Discharge Industrial Pollution Global Warming Increased sea temperature Increased ocean depth

What’s Being Done on a Global Scale 2008 declared International Year of the Reef 2006 – Bush designated 140,000 Sq Mi off Hawaii as a National Marine Sanctuary International Coral Reef Initiative

What can I do? Educate yourself and your friends Reduce your CO 2 footprint Become an informed consumer Become active in reef protection/restoration organizations
