Finally some good news for corals: reefs can be rehabilitated - life science news

Researchers have attached coral fragment to hexagonal structures called “spiders” in the center of Indonesia’s Coral Triangle to test whether it is possible to restore coral reefs. Indeed, live coral cover increased from less than 10% to more than 60%, at a cost of about $25 per square meter. Importantly, while massive coral bleaching occurred between 2014 and 2016, bleaching in the rehabilitation area was less than 5%, despite warm water conditions known to stress corals. Thus, this technique protects and rehabilitates coral reefs, giving the reefs a chance to adapt to worsening ocean conditions.
