Divers destroying reef system in The Maldives. This has to stop! Are you...

Maldivian waters are home to several ecosystems, including a variety, 187 species, of vibrant coral reefs. This area of the Indian Ocean, alone, houses 1100 species of fish, 5 species of sea turtles, 21 species of whales and dolphins, 400 species of molluscs, and 83 species of echinoderms. The area is also populated by a number of crustacean species: 120 copepod, 15 amphipod, as well as more than 145 crab and 48 shrimp species.
Among the many marine families represented are Pufferfish, Fusiliers, Jackfish, Lionfish, Oriental Sweetlips, reef sharks, Groupers, Eels, Snappers, Bannerfish, Batfish, Humphead Wrasse, Spotted Eagle Rays, Scorpionfish, Lobsters, Nudibranches, Angelfish, Butterflyfish, Squirrelfish, Soldierfish, Glassfish, Surgeonfish, Unicornfish, Triggerfish, Napoleon wrasses, and Barracudas.
These coral reefs are home to a variety of marine ecosystems that vary from planktonic organisms to whale sharks. Sponges have gained importance as five species have displayed anti-tumor and anti-cancer properties.
In 1998, sea-temperature warming of as much as 5 °C (9.0 °F) due to a single El Niño phenomenon event caused coral bleaching, killing two thirds of the nation's coral reefs.
In an effort to induce the regrowth of the reefs, scientists placed electrified cones anywhere from 20–60 feet (6.1–18.3 m) below the surface to provide a substrate for larval coral attachment. In 2004, scientists witnessed corals regenerating. Corals began to eject pink-orange eggs and sperm. The growth of these electrified corals was five times faster than untreated corals.
Scientist Azeez Hakim stated,
"Before 1998, we never thought that this reef would die. We had always taken for granted that these animals would be there, that this reef would be there forever. El Niño gave us a wake-up call that these things are not going to be there for ever. Not only this, they also act as a natural barrier against the tropical storms, floods and tsunamis. Seaweeds grow on the skeletons of dead coral."
Again, in 2016, the coral reefs of the Maldives experienced a severe bleaching incident. Over 95% of coral around the islands died, and, even after six months, 100% of young coral transplants had died. The surface water temperatures reached an all-time high in 2016, at 31 degrees Celsius in May.
Recent scientific studies suggest that the faunistic composition can vary greatly between neighbour atolls, especially in terms of benthic fauna. Differences in terms of fishing pressure (including poaching) could be the cause.
