Conditions at one of the seven natural wonders of the world,
Australia’s Great Barrier Reef, is declining, and coral bleaching caused by climate change is to blame. The world’s largest coral reef, where 400 types of coral as well as about 10 percent of the world’s fish live, has gone from “poor” to “very poor.”

The Great Barrier Reef Marine Park Authority (GBRMPA) that manages the reef released a five-year study of the reef and stated, “Significant global action to address climate change is critical to slowing the deterioration of the reef’s ecosystem and heritage values and supporting recovery.”

Located off the northeastern Australian coast, the reef is a major tourist attraction, bringing in around AU$5-6 billion (about $3.3-4 billion USD) yearly to the country’s economy. But if things don’t improve, the reef might not be around to enjoy for much longer.

While coral bleaching and climate change are the main concerns, the report suggested the 1,400-mile reef has “multiple, cumulative and increasing” problems including run-off from agriculture, coastal land clearing and crown-of-thorns starfish that eat the coral.

Another possible factor hindering the reef’s growth could be the increased use of coal mining in Australia. Statistics show that Australia’s greenhouse gas emissions have been on an upward climb for four years and counting.

As reported by Deutsche Welle, a 2012 study said that since 1985, the Great Barrier Reef has lost more than half its coral cover. Five years later, the journal Nature said 91 percent had been bleached at least once in the last 20 years.

Those concerned by the GBRMPA report have gone as far as asking UNESCO to quash the reef’s standing as a World Heritage site, which could humiliate the Australian government. In early 2019, the government did say it would spend AU$380 million to try and reproduce stronger coral.
