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.

Clues in Coral Bleaching Mystery

Coral reefs are tremendously important for ocean biodiversity, as well as for the economic and aesthetic value they provide to their surrounding communities. Unfortunately they have been in great decline in recent years, much of it due to the effects of global climate change.

‘Street-View’ Comes to the World’s Coral Reefs

Scientists are taking the public with them to study the world’s coral reefs, thanks to 360 degree panoramas from Google’s underwater street-view format. Only 1% of humanity has ever dived on a coral reef and by making the experience easily accessible the survey will help alert millions of people around the world to the plight of coral reefs…

Measuring CO2 in Green Ecosystems of the Mexican Caribbean

Jungles, forests, mangroves, swamps and lagoons are natural carbon storehouses or “sinks” in the Caribbean regions of Mexico. But now studies are being conducted to measure their capacity for absorbing carbon dioxide from the atmosphere.

Report Finds 85% of Reefs in the Coral Triangle Are Threatened: Now Available in Bahasa Indonesian

Indonesia is home to 16% of the world’s coral reefs (second only to Australia in total reef area) and the highest reef-associated population in the world, with nearly 60 million people living on the coast near coral reefs. The bahasa Indonesia edition of this report is intended to inform local and national decision-makers of the status of the country’s coral reefs and support coastal management activities in Indonesia.
