The Great Barrier Reef is facing the biggest environmental crisis in its history, with the destruction of coral reefs expected to last decades.
The damage to the reef is caused by a combination of human-caused pollution, the release of invasive species and climate change, according to the report.
Key points:The Great Barrier is the largest ecosystem on Earth, covering 2.4 billion square kilometresThe report found the world’s oceans are being destroyed at a rate of nearly 4.3 per cent a yearWhat’s the reef doing?
A report from scientists at the Australian National University (ANU) has found that the world is being destroyed by pollution from industrialised nations and the burning of fossil fuels, and they are not only causing global warming.
The research, titled The Great Australian Reef: A Report on its Status and Future, found that marine ecosystems around the globe are in grave trouble, with an average annual decline of about 4.5 per cent.
In Australia, the Great Barrier reef is the world equivalent of a football field.
The vast expanse of water covers more than 1,000 square kilometres, making it the second-largest marine ecosystem on earth, after the Atlantic Ocean.
“Our findings show that over the past 60 years, the world has lost around 4.7 per cent of the coral cover on our Great Barrier,” Dr Helen O’Sullivan, from the ANU Centre for Ocean and Atmospheric Sciences, said.
“That’s a big loss.
It’s a major blow to the Great Australian ecosystem.”
The report looked at the state of the reef across Australia and around the world.
“It is clear that the Great Barrens have been damaged for a long time and that we have had an incredible recovery,” Dr O’Neill said.
The report is based on modelling and research from the ARC Centre of Excellence for Coral Reef Studies.
“The Great Barrene is an incredibly complex ecosystem, with different species living in very different habitats, and it is a really complicated ecosystem that requires a lot of different tools to work out what is happening,” she said.
Dr O’Neil said the report’s findings highlighted the importance of a holistic approach to managing the Great Northern Reef, which covers around 1.3 million square kilometres.
“There are a number of different indicators, from where people live to how much they contribute to the ecosystem, and so they need to be understood,” she told News Corp.
The Great Northern is home to the largest reef system in the world and is home the largest fish species in the ocean.
“We need to have a better understanding of what’s happening and why,” she added.
The researchers also said the loss of the Great northern’s coral reefs will result in significant impacts on marine biodiversity and the health of the world oceans.
Dr Nick Boles from the Australian Marine Conservation Society (AMCS) said it was important for people to understand the causes of climate change and the consequences of its effects on the oceans.
“They’re not only responsible for the loss and degradation of our oceans but also the pollution that’s causing these problems,” he said.
Mr Boles said it had become “a matter of urgency” to address the reef’s damage.
“People need to understand that these systems are in danger and that’s why we need to do everything we can to protect them,” he told news.com
