Great Barrier Reef Corals in Danger

It looks like a surge of shades: red, blue, green, brown and orange corals glow in the daylight, refracted by the petty water of the Pacific Ocean. This place is a haven for countless marine organisms. The Great Barrier Reef is an area of amazing variety and charm.

The world’s biggest active habitat extends 2,000 kilometers (1,200 miles) along Australia’s northeast coastline and carries 1,500 species of fish, 400 kinds of coral, and also 4,000 types of mollusk. It includes billions of dollars annually in travel and leisure income.

But the multi-colored reef remains in threat: Researchers notify that areas of the world heritage site deal with long-term devastation if the existing El Nino, among the most potent in 2 decades, will not lessen this month. The occurrence happens when trade winds that move over seas in the tropical Pacific begin to dilute, and sea surface temperatures increase.

Corals is able to only stay alive within a thin band of ocean heat range. They survive depending on symbiosis with algae that develops within their structure – but as oceans heated, corals discharge this algae, causing coral bleaching and eventually fatality of the coral.

About 5 % of the corals in the Great Barrier Reef have actually paled. Experts worry that some regions of the reef might find the worst bleaching in fifteen years.
