Divers Are Attempting To Regrow Great Barrier Reef With Electricity (newscientist.com)
A trial is underway to restore damaged coral on the Great Barrier Reef using electricity. From a report: The reef has been severely assaulted in recent years by cyclones and back-to-back heatwaves. Nathan Cook at conservation group Reef Ecologic and his colleagues are attempting to regrow surviving coral fragments on steel frames. The frames are placed on damaged parts of the reef and stimulated with electricity to accelerate the coral's growth. Electrified metal frames have previously been used to encourage coral growth on reefs in South-East Asia, the Caribbean and the Indian Ocean. They have been shown to attract mineral deposits that help corals grow 3 to 4 times faster than normal. The technique is being trialed at a section of the reef 100 kilometres north of Cairns that was badly affected by the 2016 and 2017 mass coral bleaching events. Some coral is starting to grow back naturally, but it will take at least a decade for even the fastest-growing species to fully recover.
"Divers" are allowed to zap the Great Barrier reef to keep it alive, but when I taze homeless people to make sure they're still alive, suddenly it's a crime?!?
The process involves a creepy castle laboratory and a thunderstorm.
I'm sure there are others I've missed but these two stood out:
* Netflix has a great documentary called Mission Blue
* National Geographic's Australia's Great Barrier Reef is also good.
