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 world-famous Australian reef is providing an effective barrier against landslide-induced tsunamis, new research shows.
The aerial roots of the mangroves regulate tides and nurture the silt in the coastal ecosystem thereby sustaining diverse varieties of fish and crops…
Sunscreen contains a chemical – Oxybenzone – that scientists believe is causing massive damage to coral reefs worldwide and threatens their very existence, researchers warn.
Even with relatively low sea-level rises, mangrove forests around the Indo-Pacific region could be submerged by 2070, international research says. However the outlook in other parts of the world, where there are relatively large tidal ranges and/or higher sediment supply, was more positive.
The protest, last summer, was just the latest surrounding a planned development that will “reclaim” 700-plus hectares of land from Benoa Bay, and its adjacent mangrove swamps, at the eastern end of Bali’s international airport, to create a number of Dubai-esque islands, hosting villas, luxury hotels, a golf course, and possibly even an amusement park.
The bleaching of colorful coral is spreading into a worldwide, devastating crisis, scientists say, and they predict it will likely get worse.
An area will be set aside at the Sungei Buloh Wetland Reserve coastal trail, for a living gallery of mangrove trees, comprising about half of the true species in the world, in a move to conserve these plants.
While island societies can do little to control carbon emissions from developed nations, they can manage their local resources to enhance the ecosystem services that coastal habitats, including reefs, provide for people.
Warmer-than-normal ocean temperatures around Hawaii this year will likely lead to the worst coral bleaching the islands have ever seen.
