UPSC 2022: "Biorock technology" is talked about in which one of the following situations ?
(a)Restoration of damaged coral reefs
(b)Development of building materials using plant residues
(c)Identification of areas for exploration/extraction of shale gas
(d)Providing salt licks for wild animals in forests/protected areas
Attempt This Question
Not attemptedCorrect Answer: (a) Restoration of damaged coral reefs
Biorock (Mineral Accretion) technology passes a low-voltage electric current through submerged metal frameworks, causing calcium carbonate to precipitate and providing a substrate on which broken coral fragments grow several times faster, so it is specifically used for restoring damaged coral reefs. It is unrelated to building materials from plant waste, shale-gas exploration, or wildlife salt licks.
