Led by scientists at the Zoological Society of London, the Edge Coral Reefs project has identified 10 coral species in most urgent risk of becoming extinct.The scientists say that reefs are under pressure from a variety of threats including rising sea temperatures due to climatic instability, increased acidity(酸性), overfishing and pollution.
The Edge plan, which focuses on the most evolutionarily distinct and globally endangered species , will take a regional approach to conservation.This means focusing on the "coral triangle" around the Philippines, the West Indian Ocean around the Mozambique channel, and in the Caribbean channel.
"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.
