Application of biorock technology for coral reef restoration
Question
"Biorock technology" is talked about in which one of the following situations?
Options
Restoration of damaged coral reefs
Development of building materials using plant residues
Identification of areas for exploration/extraction of shale gas
Providing salt licks for wild animals in forests/protected areas
Explanation
Biorock technology (or mineral accretion) is an innovative method used for the restoration of damaged coral reefs.
