In Lisbon, Portugal, hundreds of protesters marched Thursday outside the U.N. Ocean Conference demanding meaningful action to halt pollution, protect marine life and slow the warming of the Earth’s seas. The conference brought together some 7,000 scientists, activists and heads of state. Greenpeace oceans policy adviser Laura Meller spoke at a protest outside the talks.

Laura Meller: “While activists are peacefully — trying to peacefully protest outside the conference venue, the real looters, the ocean destroyers, are out there depleting the oceans as we speak.”
