Johanna Johnson, a marine scientist, tells us the changes she has witnessed in coral reefs these last years.
She says: 'I have been diving on the Great Barrier Reef for 15 years and I have dived in all sorts of different reefs and I have seen how beautiful reefs can be. And since about 2002 I have started to see coral bleaching.'
