World leaders discuss protecting the planet's oceans

World leaders met on France's Atlantic coast Friday to discuss protecting the planet's oceans from threats such as overfishing and plastic pollution, and finding fairer ways to manage the seas.

The One Ocean Summit comes as European authorities are investigating a mass fish dump in the Bay of Biscay that environmental activists call an example of abuses by huge trawlers that disrupt undersea ecosystems.

French President Emmanuel Macron initiated the three-day summit in the port city of Brest with the support of the United Nations. The Brest summit was also meant to set the stage for upcoming international events, including the U.N. Ocean Conference scheduled in June in Lisbon.
