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.

Study Uncovers a Predictable Sequence Toward Coral Reef Collapse

Using data from coral reef systems across the western Indian Ocean, researchers identified how overfishing creates a series of at least eight big changes on reefs that precipitate a final collapse. This information can help assessing the health of a reef and tell when to restrict fishing in order to avoid a collapse of the ecosystem and fishery.

Haitian Divers Hope to Aid Ailing Reef

Environmental degradation is rife in Haiti, deforestation, erosion, pollution, and for the most part it is hard to miss. But for decades the country’s marine environment has suffered unseen. Its extensive coral reef system, an attraction to foreign scuba divers in the 1970s and ’80s, has largely died off, partly from sedimentation and climate change, but mostly from overfishing.

Capt. Kidd Shipwreck Site to Be Dedicated Living Museum of the Sea

This unique museum, resting in less than 10 feet of water just 70 feet from Dominican Republic’s shoreline, will give divers the opportunity to see the 17th century ship remains, which rest on the ocean’s floor and will serve as home to sea creatures and protect precious corals and other threatened biodiversity in the surrounding reef systems.

Mangroves excel at storing climate-warming carbon

Mangroves store two to four times the carbon that tropical rainforests do. Part of the reason for mangroves’ efficiency in keeping carbon locked away lies in their location in tidal zones, where their roots are often covered with sea water.
