"Coral reefs are threatened with functional extinction in the next 20-50 years, due predominantly to global climatic instability," said Catherine Head, coordinator of the reefs project."In these regions, we'll be supporting and training in-country conservationists to carry out research and implement targeted conservation actions," she said."Their projects will last initially for two years.We provide them with a whole host of tools to carry out their projects including funding and intensive training." She added.
Coral reefs are the planet's most diverse marine ecosystem(生态系统), known as the rainforests of the oceans.Despite taking up under 0.2% of the ocean floor, they provide food and shelter for almost a third of all sea life.If we lose the ecosystems, we lose not only the biodiversity (生物多样性), but we also lose the capability of people to obtain income and food from coral reefs.
Climatic instability, which leads to rising sea temperatures, causes corals to bleach.Bleaching occurs when sea temperatures rise and this causes the coral tissue to expel their symbiotic algae called zooxanthellae - these are what give the coral their colour.Bleached corals often die if the stress continues.Among the 10 species chosen to start the Edge project are the pearl bubble coral, a food source for the hawksbill(玳瑁)turtle, and the Mushroom coral, which supports at least 15 brightly colored fish.
