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.

Last Chance Beach, Battling Erosion in Barbados

Around Barbados, the most serious threat to the beaches is the loss of coral reefs through nearshore pollution, primarily caused by domestic sewage, and physical clearing. As the reefs die, they lose their ability to reduce the energy and erosive force of incoming waves.

Sundarbans’ Tigers Further Pushed Towards Extinction by Rising Sea Levels

An expected sea level rise of 28 cm above 2000 levels may cause the remaining tiger habitat in the Sundarbans to decline by 96 percent, pushing the total population to fewer than 20 breeding tigers, according to a study.

Acid Oceans Demand Greater Reef Care

The more humanity acidifies and warms the world’s oceans with carbon emissions, the harder we will have to work to save our coral reefs.

North Australia set to face more weather extremes, corals show

Like pages in a book, near shore corals can help scientists go back in time by revealing years that were unusually wet or dry, and are providing another piece of evidence that maybe suggests that we are seeing some consequences already of global warming.

18 Diving Sites Closed to Save Coral Reefs, Thailand

More than 80 percent of the corals at 18 dive sites have undergone bleaching, a symptom of severe stress caused by excessively warm water temperatures. Some of Thailand’s most popular diving sites are now off-limits to tourists for up to 14 months to allow damaged coral to recover.

Sea Urchins and Overfishing Impact on Kenya Coast’s Reefs

An 18-year study of Kenya’s coral reefs by the Wildlife Conservation Society and the University of California at Santa Cruz has found that overfished reef systems have more sea urchins, organisms that in turn eat coral algae that build tropical reef systems.

Drawing up a Global “Red List” of Vanishing Ecosystems

Now scientists are figuring out how to catalog and map the world’s most threatened ecosystems, such as mangrove, just like their familiar list of endangered species.
