Coral Reefs Declining Fast

Coral reefs in the Pacific and Indian oceans are disappearing faster than had previously been thought, a scientific study has shown.
Nearly 1,554 sq km (600 sq miles) of reef have disappeared each year since the 1960s - twice the speed at which rainforest is being lost.

The corals are vanishing at a rate of 1% per year, a decline that has begun decades earlier than expected.

Details of the survey appear in the journal Plos One.
