20. Scientists Accelerate Coral Reef Regrowth with Electricity
The conservation group Reef Ecologic is using electrical currents to stimulate regrowth of damaged coral reefs, Alice Klein reported for New Scientist in September 2018. Coral reefs are crucial components of ocean ecosystems around the world, and damage to them from climate change and destructive fishing practices has been widely reported. Damaged coral regrows slowly, and rising ocean temperatures lead to bleaching that can cause entire reef systems to collapse permanently.
