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 loss of Indonesia’s coastal mangrove forests for shrimp farming is a huge source of carbon emissions, writes Prodita Sabarini. But equally, a policy flip to preserve and recreate mangroves offers a major climate win.
North of the Aleutian Islands, submarine canyons in the cold waters of the eastern Bering Sea contain a highly productive “green belt” that is home to deep-water corals as well as a plethora of fish and marine mammals.
Mangrove forests could play a crucial role in protecting coastal areas from sea level rise caused by climate change, according to new research involving the University of Southampton.
Seven such coral reefs are being turned into islands, with harbors and landing strips by the Chinese military, and it is destroying a rich ecological network. “It’s the worst thing that has happened to coral reefs in our lifetime.”
As unusually warm ocean temperatures cover the north Pacific, equatorial Pacific, and western Atlantic oceans, NOAA scientists expect greater bleaching of corals on Northern Hemisphere reefs through October, potentially leading to the death of corals over a wide area and affecting the long-term supply of fish and shellfish.
As the ocean absorbs atmospheric carbon dioxide released by the burning of fossil fuels, its chemistry is changing.
According to a study conducted by Japanese and Filipino scientists, coral cover in Boracay Island declined by about 70.5 percent from 1988 to 2011, and the highest decrease in the 23-year period, was recorded between 2008 and 2011, as tourist arrivals rose by 38.4 percent…
World’s largest coral reef to remain on UN’s watchlist as draft ruling calls on Australia to ‘rigorously’ implement its conservation commitments. Environmental groups consider the reef – regardless of the Unesco ruling in June – technically in danger.
More than half the world’s mangroves have been lost over the last century but all of those surviving in Sri Lanka, one of their most important havens, are now to be protected in an unprecedented operation.
