Saving the ocean: 'We have to be optimistic because it's our only planet,' scientist says

One of the world's leading researchers on the state of our oceans has spoken to FRANCE 24 as the UN Ocean Conference got underway in the French Riviera city of Nice. The event is focused on "accelerating action and mobilising all actors to conserve and sustainably use the ocean". We spoke to Chris Bowler, the scientific coordinator of the Tara Ocean Programme – first about that programme and then about his reaction to French President Emmanuel Macron's opening speech at the conference in Nice.
