Planting diverse corals under the sea could help save threatened coral reef ecosystems, according to a new study published in the journal Science Advances on October 13. The study, conducted by Cody Clements and Mark Hay of the Georgia Institute of Technology, found that increasing coral reefs’ richness by ‘outplanting’ diverse species of corals could improve coral reef growth and survival. The findings come at a time when coral reefs are facing serious threats globally.
