Underwater picture showing a time capsule being lowered to the seabed at the North Pole. A “flag for the future” is attached to the glass and titanium time capsule containing the signatures of nearly three million people who wish to protect the Arctic, including actors, musicians, artists and business leaders. Greenpeace is calling for the region, currently under threat from climate change, oil companies, industrial fishing and shipping to be declared a global sanctuary and free from exploitation.
