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.

Rising Seas Will Drown Mangrove Forests Around the Indo-Pacific Region

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.

Indonesia’s Protest Generation And Biggest Punk Band Are Fighting Land Reclamation

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.
