The benefits coral reefs provide are endless. Not only are they the home of up to 9 million species but are a source of food, medicine, cosmetics and tourism. Unfortunately, coral reefs around the world are declining at a rapid rate due to ... human-related factors. In some areas of Florida and the Caribbean, coral cover has declined by 50-80 per cent in just the last three decades. Coral scientists are working hard to restore corals as fast as possible. At the Elizabeth Moore International Center for Coral Reef Research & Restoration they have managed to develop a micro-fragmentation and fusion method to speed the growth of ... important reef-building species [of coral], known for their slow growth in the wild. The fragmentation technique consists of breaking the corals into smaller pieces of 1 to 5 polyps, using a specialised saw. This stimulates the coral tissue to grow ... at 25 to 50 times the normal growth rate. The fragments are then placed in their shallow water tanks. Algal growth and debris are removed regularly. Clone fragments recognise each other so instead of fighting each other for resources [they] fuse together to form larger colonies. After 4- 12 months the fully grown corals are now ready to be planted back into the ocean or fragmented to restart the process. Labs are able to fragment, grow and recombine corals in under 2 years to a size which would normally take 100 years. They have now successfully planted more than 20,000 corals onto depleted reefs in the Florida Keys.
