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.

As Disease Ravages Coral Reefs, Scientists Scramble for Solutions

As oceans warm, coral reefs are suffering not only from bleaching but from deadly outbreaks of disease. Researchers are developing remedies, but the key question is whether these solutions can work on a large-enough scale to save vast reef systems from Florida to Australia.

Sunscreen and cosmetics compound may harm coral by altering fatty acids

Researchers say that one such chemical, octocrylene (OC), which is also in some cosmetics and hair products, accumulates in coral as fatty acid esters that could be toxic to the marine organism.

Sprouting Mangroves Restore Hopes in Coastal Myanmar

In most places, mangrove forest’s density is wafer thin thanks to rampant clearing of the mangroves for space to breed shrimps and for firewood etc. According to a recent study, Myanmar loses about 21 square km of its mangrove forests each year. But thanks to restoration efforts, the story is changing.

Managing wastewater to support coral reef health, resilience

Coral reefs provide food and livelihoods for hundreds of millions of people around the world, support more than a quarter of all marine life, and protect communities and coastlines from natural disasters—and if urgent action is not taken, we risk losing them forever.
