‘Beyond Comprehension’: In Just Two Years, Half of All Corals in ‘Forever Damaged’ Great Barrier Reef Have Died
Global warming, researchers warn, “is rapidly emerging as a universal threat to ecological integrity and function.”
Global warming transforms coral reef assemblages
There are more than 11 billion pieces of plastic debris on coral reefs across the Asia-Pacific, according to our new research, which also found that contact with plastic can make corals more than 20 times more susceptible to disease.
In our study, published today in Science, we examined more than 124,000 reef-building corals and found that 89% of corals with trapped plastic had visual signs of disease – a marked increase from the 4% chance of a coral having disease without plastic.
Globally, more than 275 million people live within 30km of coral reefs, relying on them for food, coastal protection, tourism income, and cultural value.
With coral reefs already under pressure from climate change and mass bleaching events, our findings reveal another significant threat to the world’s corals and the ecosystems and livelihoods they support.
