Seagrass solution theory for endangered coral reefs
Research headed by a Swansea University marine biologist has offered potential solution to endangered coral reefs around the world’s oceans.
Dr Richard Unsworth’s team included scientists from Oxford University and James Cook University in Australia.
They found varieties of seagrass which may reduce the acidity of water around reefs, protecting them from erosion.
Corals are worm-like creatures of around a centimetre length which live in colonies numbering millions.
Calcium carbonate released by the corals forms a protective reef around the entire group.
The survival of these corals has been threatened by carbon dioxide in the atmosphere over the last 40 years, as it has raised the acidity of the oceans, rotting the reefs in the same way as fruit and fizzy drinks can erode tooth enamel.
