Healthy Reef : biodiversity, brightly colored healthy coral

Dead/Dying Reef : coral bleaching, limited flora and fauna

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
