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.

Study Projects Unprecedented Loss of Corals in Great Barrier Reef Due to Warming

The coverage of living corals on Australia’s Great Barrier Reef could decline to less than 10 percent if ocean warming continues, according to a new study that explores the short- and long-term consequences of environmental changes to the reef.

Hidden Battles on the Reefs

coral-coastal-care

How do you drown a coral reef? The very idea seems unfathomable for animals that spend their entire lives under water. But the deep ocean is actually riddled with “drowned” coral reefs, the remains of ancient reefs that slipped into the dark ocean depths and starved without sunlight.

Coral Reefs Threatened by Changing Ocean Conditions

Erosion rates increase tenfold in areas where corals are also exposed to high levels of nutrients, according to a study published January 2015 in the journal Geology. As sea level rises, these reefs may have a harder time growing toward the ocean surface, where they get sunlight they need to survive.

UN Sends Team to Clean Up Sunderbans Oil Spill in Bangladesh

Acidic Oceans Could Quiet Coral Reefs

Scientists have been monitoring underwater sounds for decades, in part because sound propagates so efficiently underwater. But in the past 10 years, scientists have started exploring how sonic cues influence fish behavior and give a snapshot of reef health and biodiversity.

Oil Spill in Bangladesh’s Unique Mangrove Forest

tiger-mangrove

On December 12, three days after a cargo vessel collided with a tanker, oil coats mangrove trees in the Sundarbans, a delta that forms the world’s largest contiguous tidal mangrove forest—a haven for a spectacular diversity of animals. More than 90,000 gallons of oil have spilled into the rivers and creeks of the region.
