"It's full of fish, it's got corals growing on it - it's become one with the ocean."

Coral reefs worldwide have been suffering from a two-year-long global coral bleaching event, due to record high ocean temperatures.

Parts of the Great Barrier Reef have suffered the largest annual decline in coral cover since records began nearly 40 years ago, according to a new report.

While there are some ingredients in suntan lotions - like oxybenzone - that can cause environmental damage to coral reefs, there is not evidence to suggest it poses a risk to humans, Dr McCann says.

It's all part of the fourth global bleaching event, which experts say has affected more than 80% of the world's coral reefs.
