It was Charles Darwin who first realized this about corals.
He noticed that corals rolling around under his ship quickly turned white and died, but by securing the loose coral to a piece of bamboo pounded in the sand they would survive.
For this he is credited with being the first coral restorationist.
The importance of the coral reef
Coral reefs cover only 1% of all the oceans but hosts 25% of the marine life.
It is one of the most important and threatened ecosystem in the world. Why?
Coral reef guarantees biodiversity.
Coral reefs provide shelter, spawning grounds, and protection from predators.
They support organisms at the base of ocean food chains.
Coral reefs absorb wave energy and contribute to the reduction of coastal erosion.
Coral reefs provide shelters for fish communities.
Coral reefs contribute to sustain local fishermen which totally depend on reef communities.
Coral reefs attract millions of tourists every year.
