Nature Inc investigates a claim that our coral reefs are worth $30 billion a year. We go diving on the Barrier Reef, the Maldives and to the bottom of the North Sea to find out how coral reefs supply 500 million of us with food and work – but we are destroying the reefs so quickly, they could vanish entirely in less than a hundred years.
