An ultra-fine biodegradable film some 50,000 times thinner than a human hair could be enlisted to protect the Great Barrier Reef from environmental degradation, researchers said Tuesday.
The World Heritage-listed site, which attracts millions of tourists each year, is reeling from significant bouts of coral bleaching due to warming sea temperatures linked to climate change.
Scientists from the Australian Institute of Marine Biology have been buoyed by test results of a floating “sun shield” made of calcium carbonate that has been shown to protect the reef from the effects of bleaching.
