Mangrove & Coral Destruction

Widespread destruction of mangroves (Bahamas, Australia) and Coral Reefs (Caribbean, Red Sea) has resulted in the loss of some of the worlds most diverse ecosystems. As a side effect, this has greatly increased shoreline hazards and beach erosion rates. The greatest benefit of mangroves is their ability to reduce storm surge. This benefit is long-term and requires no maintenance. The 1999 super typhoon, Orissa, killed over 10,000 people in India drowning many with its powerful storm surge. This number could have been lower if the mangroves had been retained. Mangroves are lost because of clearing for development, logging, and shrimp farming. Coral reefs are lost by mining (Bali, Indonesia), sedimentation from agriculture on the upland (St. Croix, Virgin Islands), bad fishing techniques that kill corals (Pacific Islands), sedimentation from nourished beaches (Waikiki) and a host of other natural and global warming-related causes. Dubai is perhaps the single greatest example of coral reef destruction. The artificial islands built there buried vast coral reefs. Mangroves and coral reefs often provide protection for nearby beaches. Their destruction harms the beach as well.

Living Cold-Water Coral Reef Discovered Off Greenland

By sheer coincidence, Canadian researchers have discovered a reef of living cold-water corals in southern Greenland. There are several species of coral in Greenland, but this is the first time that an actual reef has been found.

Safety In Numbers? Not So For Corals

A new study revealed that global changes in climate and ocean chemistry affect corals whether scare or abundant, and often it is the dominant, abundant corals with wide distributions that are affected the most.

3D-Printed Artificial Reefs Bring Back Sea Life in Persian Gulf

Reef Arabia, a team of artificial reef designers that includes reef experts from Bahrain as well as members from Australia’s Sustainable Oceans International, has started 3D printing reef formations and sinking them off Bahrain’s coast, where overfishing has had a major impact on the health of marine life there.

Cuba’s Mangroves Dying of Thirst

In the 1960s, the Cuban government declared that storage of fresh water for times of drought or hurricanes was a matter of national security, and it began to dam up the country’s rivers. But that policy has claimed an unforeseen victim: mangroves.
