Ocean explorer Fabien Cousteau, grandson of Jacques Cousteau, has just resurfaced after spending 31 days living underwater.
He has emerged from the Aquarius Reef Laboratory in Key Largo, Florida where scientists have been studying what effects climate change and pollution are having on a coral reef.
He is now back on dry land in New York and spoke to the BBC.
