The Great Barrier Reef is the world’s largest coral reef system and the world’s largest single structure made from living organisms, stretching over 2,300 km, so big that it can be seen from outer space. In 1981 the reef was named a natural World Heritage Area for its ‘outstanding universal value’ but now thanks to climate change it is under threat. In this episode, host Lottie Dalziel speak to Theresa Fyffe from The Great Barrier Reef Foundation about the health of our reef and what’s been done to protect it.
