About Coral reefs Video



Posted on 21 February 2006  | 
Coral reefs are one of the oldest types of living systems on Earth and the variety of life they support rivals that of the tropical forests of the Amazon or New Guinea. In the tropical Pacific, for example, reefs may be home to more than 1,300 species of fish.

Nurseries for biodiversity

Coral reefs are a critical habitat along with related systems such as mangroves and sea grass beds - that serves as a nursery for much of the biodiversity of the entire oceanic system.

These biological wonders have survived tens of thousands of years of natural change, but many of them may not be able to survive the havoc wrought by humankind.

People and corals
This biodiversity of coral reefs translates directly into food security, income, coastal protection and a multitude of other benefits to people. As thousands of communities across the world will tell you, corals are essential not only to ocean health, but also to human health and well-being.
