Madagascar's coral reef under threat

Johannesburg - A new survey of coral reefs along Madagascar's southwestern coast found massive damage from coral bleaching caused by rising sea temperatures, researchers said on Thursday.

However, the survey team, funded by Conservation International and led by the conservation groups Blue Ventures and the Wildlife Conservation Society, said scientists also discovered several small reefs with corals that appeared to be resilient to rising sea temperatures and that could be used to reseed damaged reefs.
