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.

6 fascinating facts about coral reefs

Coral reefs are one of the world’s most colorful and diverse ecosystems, and though they cover only about 1 percent of the ocean floor, they have a huge effect on the health of the rest of the world. Healthy coral reefs mean healthy oceans which means healthy planet.

Historical nautical maps show loss of coral reefs

Scientists have used detailed nautical maps created by British sailors in the 1700s to study more than two centuries of coral loss in the Florida Keys. They found that over the past 240 years, the region has lost more than half of its coral structures, with some areas, particularly closer to shore, either gone completely or having lost up to 90 percent of their extent.

Satellite photos reveal how Mumbai killed its mangrove forests to risk epic floods

Mumbai is essentially a peninsula jutting into the Arabian Sea. Since the 1980s, the city’s population has more than doubled. That’s led to rapid urbanisation of the surrounding areas, as well as encroachment of the mangroves on the city’s edges.

Unique coral reef at risk as oil companies plan to drill near Amazon river mouth

Oil companies planning to drill near a vast coral reef at the mouth of the Amazon river have calculated that the unique ecosystem has a 30% chance of being affected in the event of an oil spill. The unique reef system astonished marine biologists when its existence was widely revealed last year, and is believed it could be the home for dozens of previously unknown species.

Alarm as mangrove forests at the Kenyan Coast rapidly disappear

A recent study carried out at Tudor Creek – the water body separating Mombasa Island from the mainland – shows that more than 80 per cent of mangroves along the Indian Ocean coast in the area have been wiped out.
