Scientists attempt to breed 'super coral' to save threatened reefs

Researchers in Hawaii are using an assisted evolution experiment to grow coral that can withstand the hotter and more acidic oceans caused by global warming

Scientists at a research centre on Hawaii's Coconut Island have embarked on an experiment to grow "super coral" that they hope can withstand the hotter and more acidic oceans that are expected with global warming.

The quest to grow the hearty coral comes at a time when researchers are warning about the dire health of the world's reefs, which create habitats for marine life, protect shorelines and drive tourist economies.
