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.

When the coral disappears, so will they

By now, the storyline should be familiar: We humans are burning loads of fossil fuels and chopping down the rainforest, and that’s causing the atmosphere to heat up rapidly. The ocean is storing much of that heat. Beneath the surface, there’s evidence of a mass extinction brewing. Coral are among the silent victims, and the results are undeniable. That’s true regardless of who’s in the White House…

Everglades mangroves might hold billion-dollar fix for climate change

The price of fighting climate change in South Florida has so far focused largely on the billions needed to install pumps, raise roads and retrofit the sprawling infrastructure that keeps the region above sea level. But South Florida might already have a valuable weapon that for ages has been sucking up carbon and keeping the planet cool: mangrove wetlands in the Everglades.

Mangrove protection key to survival for Senegalese community

Senegal has lost 40 percent of its mangroves since the 1970s. Mangroves are being eroded by a combination of factors, including global warming, deforestation, public works, salination of the fresh water river and drought. The establishment of a 174-square-kilometre protected area has had a positive effect on safeguarding the local environment.

Fishing communities in Kenya’s South Coast, net cash and more fish from protecting mangroves

Besides protecting mangrove forests themselves, the effort aims to improve local fisheries, as many fish species breed and raise their young in shoreline mangroves, and build resilience to worsening storm surges and coastal erosion. Mangrove forests can also help regulate coastal rainfall, ensuring supplies of water.

Can killer robots save ocean ecosystems?

Few predators can match the devastating impact of the lion fish. Since arriving in US waters in the 1980s, these fearsome creatures have left a trail of destruction along the Atlantic Coast, from Rhode Island to Venezuela. Lionfish can reduce a flourishing coral reef to barren wasteland in a matter of weeks.
