World leaders began gathering in Nice on the French Riviera on Sunday ahead of a United Nations summit to tackle a deepening crisis in the oceans driven by overfishing, climate change and pollution. Ahead of the opening, French President Emmanuel Macron told a blue finance forum in Monaco that the world has "a duty to mobilise".
The United Nations says oceans face an "emergency" and leaders gathering in Nice will be under pressure to commit much-needed money and stronger protections for the ailing seas and the people that depend on them.
