Guests use VR headsets during the launch of a new Greenpeace expedition 'Protect the Oceans', and a new report '30x30: A Blueprint for Ocean Protection', in City Hall, London, UK.
Greenpeace launches one of its biggest ever expeditions: an almost year-long pole to pole voyage from the Arctic to the Antarctic, to highlight the many threats facing the oceans and to campaign for a Global Ocean Treaty covering all seas outside of national waters.
The 'Protect the Oceans' expedition will see scientists and campaigners team up to research the threats of climate change, overfishing, plastic pollution, deep sea mining and oil drilling.
