Great Barrier Reef Has Lost Half of Its Coral in the Last 27 Years

The Great Barrier Reef has lost half of its coral in the last 27 years. The reason for the dramatic decline of the coral population in the southern portion of the great barrier reef is because of the intense cyclones that cause sickening surfs and current which kills the coral. Bleaching also impacts the population but only about ten percent. The bleaching of the corals is from the water being too hot for the corals to live and this has to do with global warming. Lastly the population growth of the coral eating crown-of-thorns starfish plays a major role in the population decline because the starfish are reproducing like crazy and are eating corals left and right as if their is a shortage of corals in the great barrier reef. Scientists at AMS says, “We can’t stop the storms, and ocean warming (the primary cause of coral bleaching) but we can act to reduce the impact of crown of thorns.” If they can come up with a way to get rid of the starfish then the corals will be on a steady increase of regeneration and growth of about 0.89% per year which is better than losing corals. This article is very important because it shows that coral reefs won’t be around much longer if we keep on destroying the earth and the ecosystems.
