Coral reefs disappearing fast

Climate change that makes seas more warmer and more acidic is having devastating effect on coral reefs, and according to marine scientists fifth of world corals is already dead. Marine scientists have warned country representatives at Poznan, Poland that if we do not cut emissions in years to come we could face major coral extinction.

Warmer and acidic seas are the biggest threats for coral population but not the only ones, there are also overfishing, pollution and invasive species, all threatening survival of coral population. Many scientists agree that if we continue with current rise in CO2 emissions there won't be any corals left by the end of this century. Only 45 % of world's corals is in healthy condition while others are affected by different ecological problems.

Coral reefs are disappearing fast. Only 45 % of world's corals is in healthy condition.

However coral reefs can recover, of course if we cut down greenhouse emissions and give not only them but many other species too a decent chance for survival. Our seas and oceans are extremely affected with climate change because they absorb carbon, more carbon means more acidic oceans and this is seriously damaging many marine ecosystems, especially corals and plankton. Corals are not only important as key parts of many marine ecosystems but are very valuable from economic point of view, some reports say about $30bn annually to the global economy through tourism, fisheries and coastal protection.
