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.

Everglades under threat as Florida’s mangroves face death by rising sea level

Florida’s mangroves have been forced into a hasty retreat by sea level rise and now face being drowned, imperiling coastal communities and the prized Everglades wetlands, researchers have found.

Global warming is transforming the Great Barrier Reef

A new study published online today in Nature shows that corals on the northern Great Barrier Reef experienced a catastrophic die-off following the extended marine heatwave of 2016.

Coral reef experiment shows: acidification from carbon dioxide slows growth

Ocean acidification will severely impair coral reef growth before the end of the century if carbon dioxide emissions continue unchecked, according to new research on Australia’s Great Barrier Reef led by Carnegie’s Ken Caldeira and the California Academy of Sciences’ Rebecca Albright.

Mangroves free of 500 tonne of plastic

Nearly 500 tonne of plastic waste was removed from eight mangrove sites across Mumbai and suburban areas over the last two months. On an average, 70-80 tonne of plastic is removed every week, and 10-15 tonne every day.

Mangroves protect coastlines, store carbon – and are expanding with climate change

Mangroves are providing extremely valuable services and may become even more important as they expand toward the poles. But according to one recent study, many mangrove ecosystems are not building enough new elevation to keep pace with sea level rise.

Scientists Pinpoint How Ocean Acidification Weakens Coral Skeletons

The rising acidity of the oceans threatens coral reefs by making it harder for corals to build their skeletons. A new study identifies the details of how ocean acidification affects coral skeletons, allowing scientists to predict more precisely where corals will be more vulnerable.

2018 International Year of the Reef, UNEP

Over the last three decades, half of the planet’s coral has died under rising water temperatures and ocean acidification. To address this global crisis, global environmental leaders and countries have named this the International Year of the Reef.
