But after a lifetime of trying to understand the enormous ecosystems that lie beneath the surface of the ocean, the 73-year-old now becomes a prophet of their extinction.

"It is the beginning of a planetary catastrophe", he tells CNN. "I was too slow to talk about it."

In 2016 and 2017, marine heat waves resulted in mass discoloration due to climate change, killing about half of the corals on the Great Barrier Reef along with many others around the world.

"Somewhere between a quarter and a third of all marine species have a part of their life cycle everywhere in coral reefs," he says. "So, you take away coral reefs and a third to quarter of all species are swept away, now that's ecological chaos, it's ecological collapse."
