Can we save the world's coral?

Corals protect humans and sustain 25% of all marine life. But
reefs are under threat from climate change, and mass bleaching
events mean that some scientists estimate they could disappear by
2100.


In this episode, Graihagh Jackson is joined by BBC CrowdScience
presenter, Caroline Steel. We go to Puerto Rico to see how
self-duplicating, carnivorous coral could be the solution. We
also speak to the scientist who helped discover what was causing
coral bleaching in the first place - back when climate change was
commonly denied.


Guests: Dr Ove Hoegh-Guldberg, Professor of Marine Studies at the
University of Queensland in Brisbane Dr Stacey Williams,
Executive Director at the Institute for Socio Ecological Research
