Leading coral reef scientists say Australia could restore the Great Barrier Reef to its former glory through better policies that focus on science, protection and conservation.
In a paper published in the journal Nature Climate Change, the authors argue that all the stressors on the Reef need to be reduced for it to recover.
An Australian Government report into the state of the Great Barrier Reef found that its condition in 2014 was “poor and expected to further deteriorate in the future.” In the past 40 years, the Reef has lost more than half of its coral cover and there is growing concern about the future impacts of ocean acidification and climate change.
“We need to move beyond the gloom and doom to identify how the decline of the Great Barrier Reef can be turned around,” says co-author Professor Terry Hughes from the ARC Centre of Excellence for Coral Reef Studies at James Cook University (JCU).
“Our paper shows that every major stressor on the Reef has been escalating for decades — more and more fishing, pollution, coastal development, dredging, and now for the past 20 years we’re also seeing the impacts of climate change.”
