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.

The lionfish, believed to have been introduced to the Atlantic coast by aquarium lovers in the 1980s, will likely wipe out most Caribbean reef fish in a decade or two. As a result, many corals that depend on herbivore fish will die and eventually turn to rubble, making shorelines more vulnerable to waves just as global warming is lifting sea levels.
In the clear waters off the coast of Peru, researchers have found a stunning new red coral species that was not previously described by scientists.
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.
Fewer deep freezes, attributable to Earth’s warming climate, have caused mangrove forests to expand northward in Florida over the past three decades, new research suggests.
The health of coral reefs offshore depend on the protection of forests near the sea, according to a new study by the Wildlife Conservation Society that outlines the importance of terrestrial protected areas to coastal biodiversity.
Seedlings of mangroves do not have an easy time to get established. Many forces of nature work against their anchorage in the soil.
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.
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.
Approximately 90 percent of Guyana’s population lives on a narrow coastline strip a half to one metre below sea level…
