So why are reefs important

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

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
